Description

[Detailed Description of the Invention] The present invention provides an operating mechanism for an automobile transmission, in particular, a shift lever supported on the floor of the vehicle so as to be able to swing in the longitudinal and lateral directions, and a a control shaft for speed change operation that is assembled so as to be movable along the direction; and a control shaft for speed change operation that is connected to the control shaft and the shift lever through shaft joints, respectively, and arranged in the longitudinal direction of the vehicle so that the shift lever moves in the longitudinal direction of the vehicle. This invention relates to an improvement in the operation mechanism of an automobile transmission, which is equipped with a control rod that is moved in the axial direction when the shift lever is operated, and rotated when the shift lever is operated in the left-right direction of the vehicle. The object of the present invention is to appropriately suppress vibrations transmitted from the transmission to the shift lever via the control shaft and control rod, and to improve the operating feeling of the shift lever.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a shift lever 10 is attached to the upper end of a support lever 12, which is attached to a shift lever housing 11 so as to be pivotable in the left-right direction of the vehicle, so as to be pivotable in the longitudinal direction of the vehicle.

This shift lever 10 also has a shaft coupling 13 at its lower end.
The control rod 14 is connected to a control rod 14 disposed along the longitudinal direction of the vehicle.

The control rod 14 is connected via a shaft coupling 20 to a control shaft 16 for speed change operation, which is attached to the transmission 15 so as to be rotatable and movable along the longitudinal direction of the vehicle. When the shift lever 10 is operated in the longitudinal direction, it is moved in the axial direction, and when the shift lever 10 is operated in the left-right direction of the vehicle, it is rotated.

The shift lever housing 11 is attached to the floor 18 by a pair of parallel support links 17.
Support rod 19 arranged above and substantially parallel to 4
It is connected to the transmission 15 via the transmission 15, and moves integrally with the transmission 15 when the transmission 15 vibrates and moves in the longitudinal direction.

In addition, the support lever 12 and the shift lever housing 11
The connecting portion P2 is provided substantially coaxially with the control rod 14 and the control shaft 16.

In this embodiment, as shown in an enlarged view in FIG. a cylindrical elastic body 22 such as rubber that slightly protrudes outward from the cylindrical body 21; a collar 23 that is fitted into the elastic body 22 and has both ends protruding outward from the elastic body 22 by a required amount; The elastic body 2 is fitted into the protrusions at both ends of the collar 23, respectively.
2, a pair of self-lubricating hard plates 24, 24 (for example, , a plate made of oil-impregnated polyacetal resin as a base material), a cylindrical body 215, an elastic body 22, a collar 23, and a plate fixed to the control shaft 16).
U-shaped racket 2 that accommodates 24.24 inside
5, and the inner hole 23 of the collar 23 is inserted into this racket 25.
The bolt 27 is formed by passing through holes 25a, 25a provided coaxially with the inner hole 23a of the collar and fastened to a nut 26.

In this embodiment configured in this way, the shift lever
10 is not in operation, even if vibrations are transmitted from the transmission 15 to the control shaft 16 due to engine vibrations (not shown), this vibration is mainly transmitted to the elastic body 22 of the shaft coupling 20.
The vibrations of the shift lever 10 are suppressed and the generation of unpleasant noise caused by the vibrations of the shift lever 10 is appropriately reduced.

Further, in this embodiment, when the shift lever 10 is operated (shift operation) in the longitudinal direction of the vehicle, the shift lever 1
0 swings around the connecting part P1 with the support lever 12, and the control rod 14 and the control shaft 1
6 in the axial direction.

At this time, in the shaft coupling 20, the elastic body 22 is bent in its radial direction (horizontal direction in the figure), so impact force, sliding, or meshing that tends to occur during a shift operation can cause an unnatural feeling such as double shift. Absorbs or alleviates the force of unpleasant sensations associated with

Furthermore, when the shift lever 10 is operated in the left-right direction of the vehicle (select operation), the shift lever 10 swings together with the support lever 12 around the connecting portion P2, thereby rotating the control rod 14 and the control shirts 1 to 16. make it move.

At this time, in the shaft joint 20, the cylindrical body 21 slightly bends both ends of the elastic body 22 in the axial direction (up and down direction in the figure), and then comes into contact with both plates 24 and 24 at both ends, so that an integral This gives the driver a good feeling, allows the operation in the selection direction to be performed reliably, and makes it easy to confirm the position after the selection operation.

As a result, it is possible to significantly improve the performance of the shift l- and select operations, and it is possible to ensure safe and comfortable driving.

In the above embodiment, an example was explained in which the shaft coupling 20, which constitutes the main part of the present invention, is used only as a shaft coupling that connects the control rod 14 and the control shaft 16. However, when implementing the present invention, This shaft joint 20 may be employed only as a shaft joint (shaft joint 13 in the embodiment) that connects the shift lever 10 and the control rod 14.
4 can be simultaneously employed in a connecting shaft joint and a shaft joint connecting the control rod 14 and the control shaft 16.

In the above embodiment, the shift lever 10 is attached to the shift lever housing 11, which is attached to the floor 1B so as to be able to swing in the longitudinal and lateral directions of the vehicle, using the support link 17. Although an example in which the present invention is applied to an operating mechanism consisting of a The present invention can also be implemented in an operating mechanism in which the shift lever 100 is assembled so as to be swingable in the longitudinal and lateral directions of the vehicle.

In addition, in FIG. 3, numeral 140 is a control rod, numeral 160 is a control shaft, numeral 150 is a transmission,
Reference numeral 190 indicates a support rod, and reference numerals 130 and 200 indicate shaft joints.
