Description

The present invention relates to a saddle-type vehicle.

Saddle-type vehicles with reflectors installed on the sides of the front wheels are known. Reflector stays are used to secure the reflectors. Routing members such as brake hoses and speed sensor cables are routed around the front forks. The layout of these routing members and reflector stays must be considered. Patent Document 1 discloses a structure in which the reflector stays protrude outward in the vehicle width direction from the front fender. In this structure, the brake hoses and speed sensor cables pass over the reflector stays in the fore-and-aft direction of the vehicle.

Patent No. 6535967

In a structure in which the wiring member passes above the reflector stay in the fore-and-aft direction of the vehicle, as in the structure of Patent Document 1, the reflector stay needs to be extended outward in the vehicle width direction, so the reflector is positioned outward in the vehicle width direction by that amount. If the reflector protrudes too far outward in the vehicle width direction, it may create resistance to the wind when the vehicle is traveling.

The object of the present invention is to provide a structure that prevents the reflector from protruding outward in the vehicle width direction.

The embodiments are described in detail below with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be combined in any desired manner. In addition, the same reference numbers are used for the same or similar configurations, and duplicate descriptions are omitted.

<Overview of saddle-type vehicles>
1 and 2 are side views (right side views) showing an overview of a saddle-ride type vehicle (hereinafter simply referred to as a vehicle) 100 according to an embodiment of the present invention. The vehicle 100 of this embodiment is exemplified as a motorcycle equipped with a front wheel FW and a rear wheel RW, but the present invention is also applicable to other types of saddle-ride type vehicles. In each drawing, an arrow D1 indicates the front-rear direction of the vehicle 100, and Fr and Rr indicate the front and rear. An arrow D2 indicates the vehicle width direction, and R and L indicate the right and left. An arrow D3 indicates the up-down direction.

The vehicle 100 includes a body frame 101 that forms the skeleton of the vehicle. A front wheel steering unit 102 is supported at the front end of the body frame 101, and a swing arm 105 is supported at the rear end so that it can swing freely. The front wheel steering unit 102 includes a pair of left and right front forks 103 (only the right front fork 103 is shown in FIG. 1) that support the front wheel FW via an axle 112, and a steering handlebar 104 that is attached to the upper part of the pair of front forks 103 via a top bridge (not shown). A front fender 6 is provided between the pair of front forks 103. The front fender 6 is supported by the pair of front forks 103 and covers the upper part of the front wheel FW.

The swing arm 105 has its front end supported by the body frame 101 so as to be freely swingable, and its rear end supports the rear wheel RW. In the area between the front wheel FW and the rear wheel RW, an internal combustion engine 106 and a transmission 107 are supported by the body frame 101. The internal combustion engine 106 is, for example, a water-cooled single-cylinder four-stroke engine. The output of the internal combustion engine 106 is transmitted to the rear wheel RW via the transmission 107 and a chain transmission mechanism (not shown). The exhaust passage 108 includes an exhaust pipe 108a connected to an exhaust port and a muffler 108b. A fuel tank 109 is disposed above the internal combustion engine 106, and a seat 110 on which a rider sits is disposed behind the fuel tank 109.

The structure around the right front fork 103 will be described with reference to Figure 2. Figure 2 is an enlarged view of the area around the front wheel FW in Figure 1.

A wheel speed sensor 4 and a brake caliper 3 are disposed on the right side of the front wheel FW. The front fork 103 is provided with a plurality of mounting portions 11-14 for mounting vehicle components. Each of the mounting portions 11-14 is a plate-shaped member protruding in the radial direction of the front fork 103. The mounting portions 11, 12, and 14 are used to fasten the front fender 6. The front fender 6 is fixed to the mounting portions 11 and 12 via a bar 60. The front fender 6 also has a plate-shaped connecting portion 61 that is substantially triangular and protrudes radially inward, and the connecting portion 61 is fixed to the mounting portion 14 by a fastener 15. The fastener 15 is formed of, for example, a bolt and a nut.

The mounting portion 11 is formed at the lower end of the front fork 103, and the wheel speed sensor 4 is also fixed here. The wheel speed sensor 4 is a sensor that detects the amount of rotation of the front wheel FW. A pulsar ring 40 is fixed to the front wheel FW. The pulsar ring 40 has a disk shape centered on the axle 112, and rotates together with the front wheel FW. The pulsar ring 40 has multiple slits arranged in a ring shape, and the wheel speed sensor 4 detects the slits.

The amount of rotation of the front wheel FW can be calculated from the detection signal of the slit output from the wheel speed sensor 4, and thus the speed of the vehicle 100 can be calculated. The detection signal of the wheel speed sensor 4 is transmitted to a control unit and instruments (not shown) by a wiring member (sensor cable) 41. The wiring member 41 has its lower end 41a connected to the wheel speed sensor 4, and is wired so as to extend upward from the wheel speed sensor 4 along the front fork 103.

A brake caliper 3 is fixed to the mounting portions 13 and 14. A brake disc 30 is fixed to the right side of the front wheel FW. The brake caliper 3 clamps the brake disc 30 by the hydraulic pressure of brake fluid supplied through a wiring member (brake hose) 31. This allows a braking force to be applied to the front wheel FW. The wiring member 31 has its lower end 31a connected to the brake caliper 3 and is wired so as to extend upward. The upper end (not shown) of the wiring member 31 is connected to a brake master cylinder (not shown) provided on the steering handle 104.

The reflector 1 is disposed behind the front fork 103 in the D1 direction. In this embodiment, the reflector 1 has a disk shape, and a reflective surface is formed on its right side. The reflector 1 is disposed rearward from the front fork 103 in the D1 direction, and a separation region R is formed between the reflector 1 and the front fork 103 in the D1 direction. The reflector 1 is supported by a reflector stay 2. The reflector stay 2 connects the reflector 1 to the mounting portion 14 of the front fork 103.

In addition to Fig. 2, Fig. 3 and Fig. 4 will be used for the explanation. Fig. 3 is a perspective view of the reflector 1 as seen from behind (the left side of the vehicle 100), with the connection part 61 of the front fender 6 omitted. Fig. 4 is an enlarged view of the vicinity of the connection part 61 in Fig. 2, showing the middle part of the wiring member 31 in a see-through state (broken line).

The reflector stay 2 is a long, thin plate-like member whose thickness direction is the D2 direction and whose surface direction is the D3 direction. In other words, the reflector stay 2 is a vertical plate-like member extending in the D1 direction. The reflector stay 2 has an end 2a on the reflector 1 side, an end 2b on the front fork 103 side, and an extension 21 between them.

At the end 2a, a hole (not shown) is formed through which the screw shaft 1a protruding from the back surface of the reflector 1 to the left in the direction D2 is inserted. A nut 1b is fastened to the screw shaft 1a, and the reflector 1 is fixed to the end 2a of the reflector stay 2. At the end 2b, a hole (not shown) is formed through which the bolt 15a of the fastener 15 is inserted. The bolt 15a is inserted through the end 2b and a hole (not shown) in the connecting portion 61 of the front fender 6, and fastened with a nut. That is, in this embodiment, the reflector stay 2 and the connecting portion 61 are fastened together to the mounting portion 14.

The extension portion 21 extends in the D1 direction through the separation region R. The routing members 31 and 41 are routed from below to above the reflector stay 2, with the routing member 31 passing on one side of the extension portion 21 and the routing member 41 passing on the other side vertically. More specifically, the routing member 31 passes vertically on the right side of the extension portion 21 with a slightly inclined attitude with respect to the D3 direction, and the routing member 41 passes vertically on the left side with a slightly inclined attitude with respect to the D3 direction and extending slightly in the D1 direction. The routing members 31 and 41 pass between the reflector 1 and the front fork 103 and intersect with the reflector stay 2, so that the reflector 1 can be prevented from protruding outward in the vehicle width direction.

It is also possible to adopt a configuration in which both of the routing members 31 and 41 pass through one side (for example, the right side or the left side) of the extension portion 21. However, as in this embodiment, by configuring the two routing members 31 and 41 to pass through different sides of the extension portion 21, the length of the extension portion 21 can be made shorter. This contributes to shortening the overall length of the reflector stay 2 in the D1 direction, and reduces the material costs.

Unlike the present embodiment, a configuration in which the routing member 31 passes on the left side of the extension portion 21 and the routing member 41 passes on the right side can also be adopted. However, in this embodiment, the lower end 31a of the routing member 31 is connected to the brake caliper 3 below the reflector stay 2, and the lower end 41a of the routing member 41 is connected to the wheel speed sensor 4 below the reflector stay 2. When viewed from the position in the D2 direction, the lower end 41a is the inside (left side) and the lower end 31a is the outside (right side). Therefore, by adopting a configuration in which the routing member 31 passes on the right side of the extension portion 21 and the routing member 41 passes on the left side as in this embodiment, these routing members 31 and 41 do not cross each other below the reflector stay 2. Therefore, there is no need to bend these routing members 31 and 41 unnecessarily, and there is no need to make a detour, so that the overall length of these can be shortened.

In addition, in this embodiment, the routing member 31 is a pipe member through which brake fluid flows, and the routing member 41 is an electrical wiring, and the routing member 31 has a larger outer diameter than the routing member 41. By configuring the routing member 31 to pass on the right side of the extension portion 21 and the routing member 41 to pass on the left side as in this embodiment, it is sufficient that the space on the inside (left side) of the extension portion 21 in the D2 direction is sufficient to allow the thin routing member 41 to pass through. Therefore, the reflector stay 2 and the reflector 1 can be positioned closer to the center in the vehicle width direction, and the reflector 1 can be prevented from protruding outward in the vehicle width direction.

A support portion 5 is provided on the inside (left side) of the extension portion 21. The support portion 5 has its locking portion 5b exposed to the outside (right side) of the extension portion 21 through a hole (not shown) provided in the extension portion 21, and is locked to the extension portion 21. The support portion 5 has a ring-shaped binding portion 5a through which the routing member 41 passes, and the routing member 41 is restricted from being displaced inward (left side) in the D2 direction. The position of the routing member 41 is stable, and interference with other surrounding components can be prevented. Therefore, there is no need to form extra clearance to prevent interference.

A clamp member 7 is provided above the reflector 1. The clamp member 7 bundles and clamps the routing members 31 and 41. The clamp member 7 has a main body 70, a cylindrical holding portion 72 that holds the routing member 31, and a cylindrical holding portion 73 that holds the routing member 41.

The clamp member 7 is supported by the connecting portion 61 via the fixing device 8 at a position above the reflector stay 2. The routing members 31 and 41 are restrained by the clamp member 7 near the reflector stay 2, stabilizing their posture. The routing member 31 can be passed through a position closer to the right side of the reflector stay 2, and the routing member 41 can be passed through a position closer to the left side. The clamp member 7 determines the passing positions of the routing members 31 and 41 relative to the reflector stay 2, so there is no need to make the extension portion 21 unnecessarily long, and the overall length of the reflector stay 2 can be shortened.

The fixture 8 is a clip-type fixture having an axis 8a. A hole 7a through which the axis 8a of the fixture 8 passes is formed in the main body 70, and the axis 8a fits into an engagement hole 61b formed in the connecting portion 61. The clamp member 7 may rotate relative to the connecting portion 61 around the axis 8a of the fixture 8. To prevent this rotation, a claw portion 71 is formed in the main body 70 of the clamp member 7, and an engagement hole 61a with which the claw portion 71 engages is formed in the connecting portion 61. This prevents the clamp member 7 from rotating relative to the connecting portion 61 , and allows the passing positions of the routing members 31 and 41 relative to the reflector stay 2 to be more reliably positioned.

As shown in FIG. 4, the routing member 31 passes through a position that overlaps with the engagement hole 61a when viewed from the right side of the vehicle 100. Because the engagement hole 61a is hidden by the routing member 31, the routing member 31 can prevent foreign objects from entering the engagement hole 61a, and the anti-rotation structure (61a, 71) of the clamp member 7 can be protected by the routing member 31.

<Other embodiments>
In the above embodiment, the configuration in which the two routing members 31 and 41 pass through the sides of the reflector stay 2 has been exemplified, but the number of routing members passing through the side of the reflector stay 2 may be one. In addition, although the brake hose and the sensor cable have been exemplified as the routing members 31 and 41, other types of routing members may be used.

In the above embodiment, the reflector stay 2 is exemplified as a plate-shaped member extending in a substantially straight line in the D1 direction, but it may be bent in the D3 direction midway (e.g., V-shaped or inverted V-shaped when viewed from the right side).
