Description

The present invention relates to an interlocking brake device.

2. Description of the Related Art Some saddle-type vehicles, such as motorcycles, are equipped with an interlocking brake device that includes a front wheel brake operator that operates the front wheel brake device and an interlocking brake operator that operates both the front wheel brake device and the rear wheel brake device.
A known configuration of an interlocking brake device is one in which a knocker is connected to the front wheel brake device via a front wheel brake cable, the knocker passes through the outer side of the pivot shaft of the front wheel brake lever and is pushed by a front wheel brake operator to rotate the front wheel brake device so as to be operable, and the interlocking brake operator is connected to the knocker via a joint and an interlocking brake cable (see, for example, Patent Document 1). Note that the pushing member in Patent Document 1 corresponds to the knocker, and the connecting member corresponds to the joint.

JP 2015-24807 A

However, in the conventional configuration, the knocker passes through the pivot shaft of the front brake lever on the outside of the vehicle body, so there is a risk that the knocker will narrow the operating space of the front brake lever. If the operating space of the front brake lever becomes narrow, it becomes necessary to enlarge the front brake lever on the outside of the vehicle body, which is detrimental to cost reduction and weight reduction.
The present invention has been made in consideration of the above-mentioned circumstances, and aims to make it easier to arrange the surrounding parts of the front wheel brake operator in a compact manner while avoiding enlarging the size of the front wheel brake operator and ensuring operation space for the front wheel brake operator.

The interlocking brake device includes a front wheel brake operator that operates a front wheel brake device and an interlocking brake operator that operates the front wheel brake device and the rear wheel brake device, and a knocker is connected to the front wheel brake device via a front wheel brake cable. The knocker is pushed by the front wheel brake operator to rotate so as to operate the front wheel brake device, and the interlocking brake operator is connected to the knocker via a joint and an interlocking brake cable. In the interlocking brake device, the knocker has a brake holder that rotatably supports the front wheel brake operator, and the knocker passes through the inside of the vehicle body of the rotation shaft of the front wheel brake operator when viewed in the axial direction of the rotation shaft.

This avoids enlarging the size of the front wheel brake operator and ensures sufficient operating space for the front wheel brake operator, while making it easier to compactly arrange the surrounding components of the front wheel brake operator.

FIG. FIG. 2 is a diagram showing the positions of a front wheel brake lever and a knocker together with the surrounding configuration.

Below, an embodiment of the present invention will be described with reference to the drawings. In the description, directions such as front, back, left, right, and up and down are the same as directions relative to the vehicle body unless otherwise specified. In addition, the symbol FR in each figure indicates the front of the vehicle body, the symbol UP indicates the upper part of the vehicle body, and the symbol LH indicates the left side of the vehicle body.

FIG. 1 is a diagram showing an interlocking brake device according to an embodiment of the present invention.
1 shows a front wheel 2a, a rear wheel 2b, and a handlebar 3 of a saddle-ride type vehicle 1 having this interlocking brake device 10. The saddle-ride type vehicle 1 is, for example, a motorcycle. The interlocking brake device 10 includes a front wheel brake lever 11 and an interlocking brake lever 12 attached to the handlebar 3, a front wheel brake device 13 that brakes the front wheel 2a, and a rear wheel brake device 14 that brakes the rear wheel 2b.

The front wheel brake lever 11 is supported on the right side of the handlebar 3 via a brake holder 21 and is a front wheel brake operator operated by the right hand of a driver (passenger) of the saddle-type vehicle. The front wheel brake lever 11 is also called a right brake lever.
The front wheel brake lever 11 is rotatable in the front-rear direction about a rotation shaft 22a that is aligned in the up-down direction. The rotation shaft 22a is also called a lever pivot. When the front wheel brake lever 11 is operated toward the handlebar 3, a front wheel brake cable 31 is pulled, and the front wheel brake device 13 is actuated. The front wheel brake device 13 is a mechanical brake device, such as a drum brake.

The interlocking brake lever 12 is supported on the left side of the handlebar 3 and is an operator that is operated with the left hand of the driver of the saddle-ride type vehicle 1. The interlocking brake lever 12 is also called the left brake lever. The interlocking brake lever 12 is freely rotatable in the front-rear direction based on a rotation shaft 22b that is aligned in the up-down direction.
A CBS (Combined Brake System) module 41 is connected to the interlocking brake lever 12. The CBS module 41 distributes the operating force of the interlocking brake lever 12 to an interlocking brake cable 32 and a rear wheel brake cable 33. The rear wheel brake cable 33 is a cable connected to the rear wheel brake device 14, and activates the rear wheel brake device 14 in response to the operation of the interlocking brake lever 12. The interlocking brake cable 32 is a cable that extends to the front wheel brake lever 11 side, and activates the front wheel brake device 13 in response to the operation of the interlocking brake lever 12.

In other words, when the interlocking brake lever 12 is operated, the rear wheel brake device 14 and the front wheel brake device 13 operate in conjunction with each other. In this case, the ratio of the braking force of the rear wheel brake device 14 to the braking force of the front wheel brake device 13 is adjusted by the CBS module 41. The rear wheel brake device 14 is a mechanical brake device, for example a drum brake.

Fig. 2 is a front oblique view of the front wheel brake lever 11 together with the handlebar 3 etc. In Fig. 2, a front wheel brake cable 31 connected to the front wheel brake device 13 and an interlocking brake cable 32 are respectively indicated by dashed lines.
An accelerator grip portion 3r that is gripped by the rider's right hand is provided at the right end of the handlebar 3. A front wheel brake lever 11 is supported in front of the accelerator grip portion 3r via a brake holder 21. The brake holder 21 integrally includes a holder base portion 21a that is fixed to the handlebar 3 and a holder protrusion portion 21b that extends from the holder base portion 21a in the direction opposite to the handlebar 3 (forward).

The holder base 21a is located on the inner side of the accelerator grip portion 3r in the vehicle width direction (corresponding to the inside of the vehicle body), and the rotating shaft 22a is inserted through the holder base 21a. The holder protrusion 21b is disposed on the inner side of the rotating shaft 22a in the vehicle width direction so as not to enter the movable range of the front wheel brake lever 11. The holder protrusion 21b is provided with a through hole 21c through which the front wheel brake cable 31 passes.
The accelerator grip portion 3r is an operator with which the driver operates the throttle. Two throttle cables 34 for transmitting the throttle operation by the driver extend to the outside from the accelerator grip portion 3r. The throttle cables 34 extend below the handlebar 3 along the handlebar 3 toward the inside of the vehicle body.

The front wheel brake lever 11 comprises a base 11a that is rotatably supported on a holder base 21a of the brake holder 21 via a pivot shaft 22a, and a lever body 11b that extends from the base 11a outward in the vehicle width direction (corresponding to the outer side of the vehicle body) in front of the accelerator grip portion 3r.
A knocker 51 to which the front wheel brake cable 31 is attached is disposed below the base 11a of the front wheel brake lever 11 and below the brake holder 21. The knocker 51 is supported by the holder base 21a so as to be rotatable about the rotation shaft 22a. The front wheel brake device 13 can be actuated by the rotation of the knocker 51. The knocker 51 is a member that is pushed by the front wheel brake device 13, and is therefore also referred to as a pushing member.

A joint 61 to which the interlocking brake cable 32 is attached is provided below the handlebar 3. The joint 61 is connected to the knocker 51, and functions as a connection part that connects the knocker 51 and the interlocking brake cable 32. When the interlocking brake lever 12 is operated, the knocker 51 rotates via an interlocking mechanism consisting of the CBS module 41, the interlocking brake cable 32, and the joint 61, and the front wheel brake device 13 can be operated. The joint 61 is also referred to as a connection member, as it is a member that connects the knocker 51 and the interlocking brake cable 32.

Next, the knocker 51 and its surrounding structure will be described in detail.
Fig. 3 is a diagram showing the knocker 51 together with the surrounding structure from the front of the vehicle body, and Fig. 4 is a diagram showing the knocker 51 and the joint 61 together with the surrounding structure from below. Both Fig. 3 and Fig. 4 show the case where the front wheel brake lever 11 is in a non-operated state.
As shown in Figure 3, the knocker 51 is integrally provided with a pivot shaft insertion portion 51a through which the pivot shaft 22a of the front wheel brake lever 11 is inserted, a cable attachment portion 51b to which the front wheel brake cable 31 is attached, and an extension portion 51c extending from the cable attachment portion 51b to a position where it is connected to the joint 61.
The pivot shaft insertion portion 51a is located below the base portion 11a of the front wheel brake lever 11 and is supported so as to be rotatable about the pivot shaft 22a. This allows the knocker 51 to be rotatable about the pivot shaft 22a. The front wheel brake lever 11 and the knocker 51 are each independently rotatable about the pivot shaft 22a.

As shown in Figures 3 and 4, the cable attachment portion 51b is located below the base 11a of the front wheel brake lever 11. The cable attachment portion 51b has a cable locking hole 51h, which locks the end of the front wheel brake cable 31, at a position shifted from the pivot shaft insertion portion 51a to the radial outside of the pivot shaft 22a (in this embodiment, in front of the pivot shaft 22a). This allows the front wheel brake cable 31 to move to the side that activates the front wheel brake device 13 when the knocker 51 rotates with the pivot shaft 22a as a reference.

3, the pivot shaft insertion portion 51a and the cable attachment portion 51b are provided at positions overlapping the brake holder 21 in the vehicle width direction. Since the vehicle width direction corresponds to a direction perpendicular to the pivot shaft 22a, the pivot shaft insertion portion 51a and the cable attachment portion 51b overlap the brake holder 21 in a direction perpendicular to the axial direction of the pivot shaft 22a. Note that "the vehicle width direction corresponds to a direction perpendicular to the pivot shaft 22a" is not limited to the case where the vehicle width direction coincides with the direction perpendicular to the pivot shaft 22a, but also includes a mode in which the vehicle width direction is a direction close to the direction perpendicular to the pivot shaft 22a.
Furthermore, it is only necessary that the rotating shaft insertion portion 51a and part or all of the cable attachment portion 51b overlap with the brake holder 21 in a direction perpendicular to the axial direction of the rotating shaft 22a.

The cable attachment portion 51b has a push-down portion 51p that protrudes from the cable locking hole 51h to the outside of the vehicle body (corresponding to the outside in the vehicle width direction). The push-down portion 51p is a portion that is pushed down by a knocker movable portion 11k provided on the front wheel brake lever 11.
Here, the knocker movable part 11k is located between the lever body 11b and the base part 11a, and forward of the pivot shaft 22a and outboard in the vehicle width direction. The knocker movable part 11k has a shape that protrudes forward and downward from the lever body 11b, and when the lever body 11b is operated toward the accelerator grip part 3r, it presses the push-down part 51p toward the accelerator grip part 3r. This causes the cable attachment part 51b to rotate in the same direction as the front wheel brake lever 11, moving the front wheel brake cable 31 to the side that activates the front wheel brake device 13, and the front wheel brake device 13 can be activated.

The front wheel brake lever 11 and the knocker 51 are biased in the direction opposite to the brake actuation side by a biasing member 17 shown in Fig. 2. Therefore, when the front wheel brake lever 11 and the interlocking brake lever 12 are not operated, the front wheel brake lever 11 and the knocker 51 are held in a non-operation position (corresponding to the position shown in Figs. 2 to 4) that does not actuate the front wheel brake device 13.
In this configuration, as shown in Fig. 4, the knocker movable part 11k protrudes forward of the front wheel brake lever 11, so that the knocker movable part 11k can define the range of the operation space of the front wheel brake lever 11. This makes it possible to prevent the driver's hand from moving to the base part 11a side, which is outside the operation space of the front wheel brake lever 11.

As shown in Figure 3, the extension portion 51c of the knocker 51 protrudes downward from the knocker movable portion 11k, and then extends rearward, below the brake holder 21 and passing inside the vehicle width direction (corresponding to inside the vehicle body) of the pivot shaft 22a of the front wheel brake lever 11.
4, the extension portion 51c of the knocker 51 has a bent shape extending along the circumferential direction of the rotating shaft 22a when viewed in the axial direction of the rotating shaft 22a. This allows the extension portion 51c of the knocker 51 to be disposed close to the rotating shaft 22a. An extension end 51t of the extension portion 51c overlaps with the handlebar 3 in the vertical direction, and a joint 61 is connected to the extension end 51t.

The joint 61 has a long hole 61h that extends in the longitudinal direction of the joint 61. The shaft member 51v provided at the extension end 51t of the extension portion 51c is inserted into the long hole 61h, so that the joint 61 is connected to the knocker 51 in a freely slidable and rotatable manner with respect to the shaft member 51v.

A pulling force is applied to the joint 61 by the interlocking brake cable 32 in the direction indicated by the symbol X in FIG. 4. Therefore, the joint 61 is held in a state along this pulling direction X. As shown in FIG. 4, the pulling direction X is along the tangent direction of a circle C1 whose center is the pivot shaft 22a, which is the pivot point of the knocker 51. Note that "the pulling direction X is along the tangent direction of the circle C1" is not limited to the case where the pulling direction X coincides with the tangent direction of the circle C1, but also includes a case where the pulling direction X is close to the tangent direction of the circle C1.

When the interlocking brake lever 12 is operated, the joint 61 is pulled in the pulling direction X by the interlocking brake cable 32, and the knocker 51 rotates counterclockwise in FIG. 4 around the rotating shaft 22a, thereby activating the front wheel brake device 13. As described above, the pulling direction X is along the tangential direction of the circle C1 centered on the rotating shaft 22a, which is the rotation fulcrum of the knocker 51, so that when the joint 61 is pulled in the pulling direction X, the joint 61 temporarily moves along the tangential direction of the circle C1 centered on the rotating shaft 22a. This makes it easier to rotate the knocker 51 smoothly by the joint 61, and also makes it easier to reduce the tensile force of the joint 61 (corresponding to the tensile force of the interlocking brake cable 32) required to rotate the knocker 51.
In this embodiment, at the point at which operation of the interlocking brake lever 12 begins (corresponding to the point at which tension on the joint 61 begins by the interlocking brake cable 32), the joint 61 temporarily moves along the tangent direction of the circle C1. However, this is not limited to this, and the joint 61 may be configured to temporarily move along the tangent direction of the circle C1 at any position within the operation range of the interlocking brake lever 12.

Fig. 5 is a diagram showing the positions of the front wheel brake lever 11 and the knocker 51 together with the surrounding configuration. In Fig. 5, the front wheel brake lever 11 and the knocker 51 are shown by solid lines when they are in a non-operation position that does not operate the front wheel brake device 13, and the front wheel brake lever 11 and the knocker 51 are shown by two-dot chain lines when they are in an operation position that operates the front wheel brake device 13.
As shown in Fig. 5, the knocker 51 passes through the vehicle body inner side of the pivot shaft 22a of the front wheel brake lever 11. This prevents the knocker 51 from interfering with the operation of the lever body 11b of the front wheel brake lever 11. The knocker 51 is also bent along the pivot shaft 22a when viewed in the axial direction of the pivot shaft 22a. This allows the knocker 51 to be positioned close to the pivot shaft 22a.

When the front wheel brake lever 11 is operated, the front wheel brake lever 11 rotates counterclockwise in Figure 5 around the pivot shaft 22a as a fulcrum, and the knocker 51 rotates counterclockwise around the pivot shaft 22a as a fulcrum by the knocker movable part 11k, thereby activating the front wheel brake device 13.
As shown in Figure 5, the joint 61 is connected to the extended end 51t of the knocker 51. Therefore, when viewed in the axial direction of the pivot shaft 22a shown in Figure 5, the joint 61 remains in a position overlapping with the brake holder 21 and the handlebar 3, and operation of the lever body 11b of the front wheel brake lever 11 is not hindered.

In this configuration, the knocker 51 does not interfere with the operation of the lever body 11b of the front wheel brake lever 11, and therefore the situation in which the operation space of the front wheel brake lever 11 is narrowed by the knocker 51 is avoided. This makes it possible to ensure the operation space of the front wheel brake lever 11 without enlarging the lever body 11b on the outer side in the vehicle width direction. In addition, the knocker 51 can be arranged close to the rotating shaft 22a and the brake holder 21, making it easier to arrange the brake holder 21, the knocker 51, etc., located around the front wheel brake lever 11 in a compact manner.
In this configuration, the knocker 51 is positioned close to the rotating shaft 22a and is positioned so that it overlaps the brake holder 21 when viewed in the axial direction of the rotating shaft 22a, thereby allowing the brake holder 21 and the knocker 51 to be compactly positioned around the rotating shaft 22a.

Figure 5 shows the position P1 of the inner end of the knocker 51 and the position P2 of the inner end of the brake holder 21 (Figure 5 corresponds to the position of the inner end of the holder protrusion 21b) when viewed in the axial direction of the pivot shaft 22a.
Position P1 of the inside end of the knocker 51 is located outside in the vehicle width direction (corresponding to the outside of the vehicle body) from position P2 of the inside end of the brake holder 21. This prevents the knocker 51 from protruding inward in the vehicle width direction from the brake holder 21, and prevents the space required for arranging the brake holder 21 and the knocker 51 from expanding inside the vehicle body.

In addition, whether the front wheel brake lever 11 and the knocker 51 are in a non-operating position (position shown by a solid line) that does not operate the front wheel brake device 13, or in an operating position (position shown by a two-dot chain line) that operates the front wheel brake device 13, the knocker 51 remains in a position overlapping the front wheel brake lever 11 and the brake holder 21 in the vertical direction of the vehicle body, which corresponds to the axial direction of the pivot shaft 22a. This allows the front wheel brake lever 11, the brake holder 21, and the knocker 51 to be arranged compactly in the fore-aft direction of the vehicle body, etc.

In addition, the joint 61 moves in the vehicle width direction corresponding to the direction X along the handlebar 3 in response to the operation of the interlocking brake lever 12, and is located in an area overlapping with the brake holder 21 and the handlebar 3 in the vehicle vertical direction corresponding to the axial direction of the rotation shaft 22a. This allows the joint 61, the brake holder 21, and the handlebar 3 to be arranged compactly in the vehicle front-rear direction, etc.
Furthermore, since the joint 61 is positioned inward in the vehicle width direction from the rotating shaft 22a, the joint 61 does not interfere with the operation of the front wheel brake lever 11, and the front wheel brake lever 11 does not need to be large in the vehicle width direction.

As described above, this embodiment has a brake holder 21 that rotatably supports the front wheel brake lever 11 that functions as a front wheel brake operator, and the knocker 51 passes through the vehicle body inside of the pivot shaft 22a of the front wheel brake lever 11 when viewed in the axial direction of the pivot shaft 22a. This configuration makes it easy to compactly arrange the peripheral parts including the brake holder 21 and the knocker 51 located around the front wheel brake lever 11 while avoiding an increase in size of the front wheel brake lever 11 and ensuring an operating space for the front wheel brake lever 11. This is therefore advantageous for making the area around the handle compact, reducing costs and weight, etc.
Furthermore, since the knocker 51 overlaps the brake holder 21 when viewed in the axial direction of the pivot shaft 22a of the front wheel brake lever 11, the brake holder 21 and the knocker 51 can be arranged compactly around the pivot shaft 22a.

The knocker 51 has a shape that bends along the pivot axis 22a, and the joint 61 moves temporarily along the tangent direction of a circle C1 centered on the pivot axis 22a when operated by the interlocking brake lever 12 that functions as an interlocking brake operator. This configuration allows the knocker 51 to be arranged compactly close to the pivot axis 22a. In addition, the joint 61 moves temporarily along the tangent direction of the circle C1 centered on the pivot axis 22a when operated by the interlocking brake lever 12, making it easier to rotate the knocker 51 smoothly when operating the interlocking brake lever 12 and reducing the operating force required to rotate the knocker 51.

In addition, the position P1 of the inside end of the knocker 51 is located on the outside of the vehicle body relative to the position P2 of the inside end of the brake holder 21, which prevents the space required for arranging the brake holder 21 and the knocker 51 from expanding inside the vehicle body.

Furthermore, the cable attachment portion 51b of the knocker 51 overlaps with the extension portion 51c of the knocker 51 in the axial direction of the pivot shaft 22a, which corresponds to the vertical direction of the vehicle body, and overlaps with the brake holder 21 in the vehicle width direction (corresponding to the direction perpendicular to the axial direction of the pivot shaft 22a in this embodiment). According to this configuration, the space required for arranging the cable attachment portion 51b, the extension portion 51c, and the brake holder 21 of the knocker 51 in the vehicle width direction can be reduced, making it easier to make the vehicle more compact in the vehicle width direction.
The axial direction of the pivot shaft 22a is not limited to the vertical direction of the vehicle body, but may be inclined relative to the vertical direction of the vehicle body or may be a direction different from the vertical direction of the vehicle body. Also, the direction perpendicular to the axial direction of the pivot shaft 22a is not limited to the horizontal direction of the vehicle body, but may be inclined relative to the vertical direction of the vehicle body or may be a direction different from the vertical direction of the vehicle body.

The handlebar 3 also has an accelerator grip portion 3r that functions as a grip portion at the outer end of the vehicle body, and the extension portion 51c of the knocker 51 is formed in a shape that is bent so that it passes through the inside of the vehicle body corresponding to the opposite side of the accelerator grip portion 3r with respect to the rotation shaft 22a. As a result, the space for the accelerator grip portion 3r is not obstructed by the knocker 51, and the knocker 51 can be arranged compactly while securing the space for the accelerator grip portion 3r.

The front wheel brake lever 11 also has a knocker movable part 11k that rotates the knocker 51, and the knocker movable part 11k protrudes toward the front side of the vehicle body of the front wheel brake lever 11. This allows the knocker movable part 11k to function as a regulating member that regulates the operating range of the front wheel brake lever 11, making it easier to make the front-rear direction more compact and simplify the structure compared to the case where a dedicated regulating member is provided.

The above-described embodiment shows one aspect of the present invention, and the present invention is not limited to the above-described embodiment, and the configuration of the details, etc. may be appropriately changed. For example, the shape and layout of each component of the interlocking brake device 10 may be appropriately changed.
In addition, in the above embodiment, a case has been described in which the front wheel brake operator is the front wheel brake lever 11 and the interlocking brake operator is the interlocking brake lever 12, but this is not limited to this, and either or both of the front wheel brake operator and the interlocking brake operator may be operators that are operated by something other than the hand (for example, the foot).
In addition, the present invention has been described as being applied to the interlocking brake device 10 of a motorcycle, but the present invention is not limited to this and may be applied to an interlocking brake device of any saddle-ride type vehicle. Note that the saddle-ride type vehicle is not limited to a two-wheeled vehicle, but may be a three-wheeled vehicle, a four-wheeled vehicle, or the like.
