[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual shift operating device for shifting a transmission of a vehicle.

[0002]

2. Description of the Related Art A manual shift operating device is provided with a base of an operating lever provided in a driver's seat for a one-way shifting operation (shifting operation) and a crossing shifting operation (selecting operation). A transmission link mechanism is provided, and the link mechanism and a transmission located at a far position are connected by two shift cables for shift operation and select operation.

However, in such a manual shift operating device, when the driver further applies a force in the operating direction to the operating lever after the transmission has been shifted to a specific gear, the bending of the link mechanism near the operating lever is caused. The operation lever may still rotate beyond the gear shift position due to play, play, flexure of the change gear, or play inside the transmission. There is a problem that damage is likely to occur.

In order to solve such a problem, conventionally, a compression spring is provided in the vicinity of the operation end position of the fork shaft in the transmission, and the compression of the compression spring absorbs the load on the transmission cable due to the excessive operation of the operating lever. However, a structure for preventing an overload on the transmission cable has been proposed (Japanese Patent Laid-Open No. 61-180049).

In this conventional structure, on the other hand, the stopper for restricting the tilting operation of the operating lever is provided below the ball bearing, which is the tilt center of the operating lever (on the side of the transmission), so that the driver can perform the shifting operation. When tilting the operating lever later, the fork shaft first reaches the gear position (shift position) on the transmission side, then the compression spring is compressed, and finally the operating lever comes into contact with the stopper. The rotation of the lever is restricted by the stopper, and as a result, the overload on the transmission cable is prevented.

[0006]

However, in general, the operation lever of the vehicle is configured to perform the shift operation and the selection operation as described above. In this conventional configuration, the operation lever is operated in one direction. Only the operation is considered, and no measures are taken for the operation in the crossing direction.

Further, in the conventional structure, when the operation lever is still operated after the gear shift operation, the compression spring is compressed before the operation lever abuts the stopper.
When the compression spring is compressed, a load is still applied to the link mechanism and the shift cable around the shift shaft.

Further, in recent vehicles, it is required that the driving feeling is good and the operation feeling is clear. Especially, in the vehicle equipped with a manual shift type transmission, the operation lever is operated. Where it is required to have a rigid feeling, in the above-mentioned conventional configuration, the deflection of the operating lever, the deflection or rattling of the link mechanism, the deflection of the speed change cable, the rattling or deflection in the transmission near the operation end point. In addition to being sensed by the driver, the reaction force of the compression spring is transmitted to the driver's hand, so this reaction force is also sensed by the driver as a kind of flexure, and there is a drawback that the sense of operation lacks rigidity. is there.

Further, since the space around the operation lever is limited especially in the column shift type operation lever, when the above-mentioned conventional structure is applied, the stroke of the operation lever after the gear shift operation becomes large and the operation lever is moved. There is a drawback that it gives a driver anxiety that it may interfere with or may interfere with peripheral parts such as a dashboard and a steering wheel. Further, if the operating lever is designed to be short in order to avoid this, there is a drawback that the load of gear shifting operation becomes heavy.

Therefore, the present invention has been made to solve the above problems, and an object thereof is not only in the tilting direction of the operating lever but also in the operation in the intersecting direction thereof, a link mechanism and a speed change cable near the operating lever. Can be completely prevented from overloading, and the operating lever feels rigid, and the driver does not have to worry that the operating lever will or will interfere with peripheral parts. Moreover, it is an object of the present invention to provide a manual shift operating device that can perform a shift operation with a light operating force.

A simple configuration can be achieved.

Further, since the excessive operation of the operating lever is restricted, the effect of the flexure of the link mechanism, the play of the link mechanism, the flexure of the transmission cable, the play in the transmission and the flexure is removed to give the operation lever a sense of rigidity. Moreover, the driver does not feel anxiety that the operation lever will interfere with or may interfere with the peripheral parts. Further, since it is not necessary to design the operating lever to be short in order to avoid interference, the gear shifting operation can be performed with a light operating force. Further, since both the tilt control piece and the tilt stopper are arranged on the operating side with respect to the tilt center of the shift shaft, the influence of the deflection of the shift shaft itself can be eliminated, and the sense of rigidity can be further enhanced in terms of operational feeling.

According to a second aspect of the present invention, the rotation restricting piece is integrally formed with a base of an arm which is fixed to the shift shaft and constitutes a part of the transmission mechanism. The manual shift operating device according to claim 1.

The manual shift operating device according to claim 1, wherein the manual shift operating device is movably held, and the rotation stopper is integrally formed on the tilting control piece.

According to the third aspect of the present invention, since the tilt stopper is integrally formed with the rotation stopper, the device can be designed simple and highly rigid by reducing the number of parts.

On the other hand, a pin 6b is attached to the lower end portion 6a of the shift arm 6, and the shift cable 10 is connected to this pin 6b. One recess 6c is provided on each of the left and right sides of the upper end (base) of the shift arm 6 in the figure, and one contact surface 6d is formed at each of the upper and lower ends of each recess 6c in the figure. The shape of each contact surface 6d is an arcuate concave surface corresponding to the shape of the left and right rotation stoppers 5a of the tilt control piece 5.

The shift cable 10 and the select cable 9 are inserted into the cable sleeve, and as shown in FIG. 5, the shift input lever 13 and the shift input lever 13 of the transmission 25 are passed through the lever side bracket 11 and the transmission side bracket 12. It is connected to the select input lever 14. The shift cable 10 and the shift input lever 13, and the select cable 9 and the select input lever 14 are connected to each other via rubber bushings (not shown).

The transmission 25 has three sets of shift stages corresponding to the upper, center (neutral) and lower operating positions in one-way operation (shift operation) of the operating lever 21 and the shift shaft 1. However, these three sets of shift speeds are set to the front side, the center, and the vehicle body in the operation (selection operation) in the intersecting direction of the shift shaft 1.
The selection is made by switching the three operation positions on the rear side. In addition, a predetermined play is provided in the axial direction of the shift fork shaft at the end of a shift fork shaft (not shown) built in the transmission 25, and the shift fork shaft slides beyond the gear shift operation position. Sliding of the shift fork shaft is not restricted within the transmission 25 even if it moves.

Next, the first aspect of the present invention constructed as described above
The operation of the manual shift operating device according to the embodiment will be described. Figure 3
When the driver shifts the operation lever 21 and the shift shaft 1 in the axial direction (direction A in FIG. 3), the shift arm 6 pivots with respect to the tilt control piece 5,
As a result, the shift cable 10 is operated.

Even if the driver still attempts to shift the shift shaft 1 after the shift operation, the shift shaft 1
The contact surface 6d of the shift arm 6 fixed to the
In the vicinity of the shift operation position on the shift side of 5, the shift shaft 1 comes into contact with the rotation stopper 5a of the tilt control piece 5.
Excessive shift operation is restricted, and therefore shift shaft 1
Shift cable 10 that constitutes a transmission mechanism connected to
The lever-side bracket 11, the transmission-side bracket 12, and the shift input lever 13 of the transmission 25 are not overloaded. Therefore, the flexure / backlash of the link mechanism 31 and the flexure / damage of the shift cable 10 can be prevented, and it is not necessary to design them with high strength, and a simple structure can be obtained.

Further, in the present embodiment, the rotation stoppers 5a are symmetrically arranged one by one with the shift shaft 1 interposed therebetween, and
Each contact surface 6d and each rotation stopper 5a of the tilt control piece 5
Since the left and right upper and lower right and upper and lower intervals are equal to each other at four positions, the abutment surface 6d is rotated on the upper left side and the lower right side, or on the lower left side and the upper right side, respectively, according to the turning of the shift arm 6. The stopper 5a abuts at the same time. Therefore, when the contact surface 6d and the rotation stopper 5a contact each other, the torques acting on the shift shaft 1 have the same magnitude and the directions thereof are opposite to each other by 180 degrees. , Sleeve 3 supporting shift shaft 1, holder 2
There is an advantage that a large load in a specific one direction is not applied to them and these wear and damage can be prevented.

On the other hand, as shown in FIG. 1, when the driver selects the operating lever 21 and the shift shaft 1 in the vehicle longitudinal direction (direction B in FIG. 1) about the shaft 3a, the shift shaft 1
Also, the sleeve 3 pivots with respect to the shaft 3a, the select arm 4 pivots in the direction C in the figure via the pin 4c, and the select cable 9 is operated.

Here, even when the driver still tries to select the operating lever 21 and the shift shaft 1 after the select operation, one side end surface 5b of the tilting control piece 5 attached to the shift shaft 1 has a transmission. In the vicinity of the shift operation position on the select side of No. 25, since it abuts on one side edge 2d of the through hole 2b of the holder 2, excessive select operation of the shift shaft 1 is restricted, and therefore, the link connected to the shift shaft 1 is restricted. Overload is not applied to each part of the mechanism 31, the select cable 9, the lever-side bracket 11, the transmission-side bracket 12, and the select input lever 14 of the transmission 25, which constitute the transmission mechanism. Therefore, in the first embodiment, even in the select operation of the shift shaft 1,
The play of the link mechanism 31 and the extension / damage of the select cable 9 can be prevented, and it is not necessary to design them with high strength, and a simple structure can be obtained.

Further, since the shift operation and the select operation of the shift shaft 1 are restricted by the respective rotation stoppers 5a of the tilt restricting piece 5 and one side edge 2d of the through hole 2b of the holder 2 as described above, the link mechanism 31 is provided. Can be eliminated, and the effects of the play of the shift cable 10 and the select cable 9 and the play and flexure in the transmission 25 can be eliminated, and as a result, the operation lever 2
The operation feeling of No. 1 can be made to have a sense of rigidity, and the driver is not anxious that the operation lever 21 interferes with or may interfere with peripheral parts. Moreover, since the through hole 2b is arranged on the driver side with respect to the shaft 3a which is the tilt center of the shift shaft 1, the influence of the deflection of the shift shaft 1 can be eliminated. In addition, the operating lever 2
Since it is not necessary to design 1 to be short, there is an advantage that the gear shifting operation can be performed with a light operating force.

Next, a second embodiment of the present invention will be described. The second embodiment has a configuration in which a lever regulating piece 15 shown in FIG. 6 is used in place of the tilt regulating piece 5 in the first embodiment.

The lever regulating piece 15 has projecting pieces 15a which sandwich the shift shaft 1 and project to the left and right, and contact surfaces 15b are formed on the upper and lower surfaces of each projecting piece 15a. The lever regulating piece 15 is fixed to the shift shaft 1 by welding. Further, the lever regulation piece 15 is provided with the through hole 2 of the holder 2.
Insert in b. The upper and lower inner side surfaces 2c of the through hole 2b function as rotation stoppers in the present invention, and the side edges 2d of the through hole 2b function as tilting stoppers in the present invention. It functions as a stopper frame in the present invention.

Therefore, when the operating lever 21 and the shift shaft 1 are shifted in the axial direction (direction A in FIG. 6) of the lever regulating piece 15, the lever regulating piece 15 turns together with the shift shaft 1 and comes into contact with each of the projecting pieces 15a. The surface 15b comes into contact with the upper and lower inner side surfaces 2c of the through hole 2b in FIG.
The distance between each contact surface 15b and each inner surface 2c is
The abutment surfaces 15b of a are set so as to substantially abut the upper and lower inner side surfaces 2c of the through hole 2b at the gear shift operation position of the transmission 25.

When the shift shaft 1 is selected in the longitudinal direction of the vehicle body (direction B in FIG. 6), the lever regulating piece 15 fixed to the shift shaft 1 moves left and right in the drawing, The side end surface of the through hole 2b comes into contact with the side end surface 15c of the lever regulating piece 15 and the side end surface 2 of the through hole 2b.
The distance 24 from d (see FIG. 6) is a distance at which the lever regulating piece 15 should substantially contact the side end surface 2d of the through hole 2b at the gear shift operation position of the transmission 25.

The structure of the other parts of the second embodiment is the same as that of the first embodiment, and the description thereof will be omitted.

In the second embodiment, however, when the driver shifts the operating lever 21 and the shift shaft 1 in the axial direction (direction A in FIG. 6), the shift arm 6 turns, and The shift cable 10 is operated by. Here, the driver still operates the operation lever 2
1 and shift shaft 1
Since each contact surface 15b of the lever regulating piece 15 fixed to the shift shaft 1 contacts each upper and lower inner side surfaces 2c of the through hole 2b in the vicinity of the operation end point on the shift side of the transmission 25,
Excessive shift operations of the operating lever 21 and the shift shaft 1 are restricted.

Further, the driver moves the operation lever 21 and the shift shaft 1 around the shaft 3a in the longitudinal direction of the vehicle body (direction B in FIG. 6).
When the select operation is performed, the shift shaft 1 turns about the shaft 3a, the select arm 4 turns in the direction C in FIG. 6, and the select cable 9 is operated. Here, even when the driver still tries to select the operation lever 21 and the shift shaft 1 after the gear shifting operation, the one side end surface 15c of the lever regulating piece 15 fixed to the shift shaft 1 has the transmission 25.
In the vicinity of the operation end point on the select side, since it abuts on one side end surface 2d of the through hole 2b, excessive select operation of the operation lever 21 and the shift shaft 1 is restricted.

Therefore, also in the second embodiment, as in the case of the first embodiment, the shift cable 10, the select cable 9, the lever side bracket 11, the transmission side bracket 1 which constitute the transmission mechanism.
2, the shift input lever 13 and the select input lever 14 of the transmission 25 are not overloaded, and the play of the link mechanism 32, the shift cable 10, and the select cable 9 are prevented.
It is possible to prevent the elongation and damage of the above, and it is not necessary to design them with high rigidity, and it is possible to have a simple structure.
Further, as in the case of the first embodiment, the effects of the play of the link mechanism 32, the expansion of the shift cable 10 and the select cable 9, and the play and flexure in the transmission 25 can be eliminated, and as a result, the operation lever 21 The operation feeling can be made to be rigid, and the driver is not anxious that the operation lever 21 interferes with or may interfere with peripheral parts. Moreover, since the through hole 2b is arranged on the driver side with respect to the shaft 3a which is the tilt center of the shift shaft 1, the influence of the deflection of the shift shaft 1 can be eliminated.

Further, according to the second embodiment, the lever regulating piece 15 and the through hole 2b are brought into contact with each other without using the tilt regulating piece 5 as in the first embodiment, and
Since both the turning operation and the tilting operation of the shift shaft 1 are restricted, the device can be configured more simply and with high rigidity by reducing the number of parts.

It is possible to prevent the bending and play of the link mechanism and the bending and damage of the speed change cable not only in the tilting direction of the shift shaft fixed to the operation lever but also in its rotating direction, and it is not necessary to design these with high strength, which simplifies It can be configured in various ways.

Further, since the excessive operation of the operating lever is restricted, the effect of the flexure and rattle of the link mechanism, the flexure of the transmission cable, the rattling and flexure in the transmission is eliminated, and the operating feeling of the operating lever is made rigid. Moreover, the driver does not feel anxiety that the operation lever will interfere with or may interfere with the peripheral parts.
