[Conventional technology]

Conventionally, some automatic vehicles (vehicles equipped with an automatic transmission) have adopted a handle shift mechanism. In such a steering wheel shift mechanism, a control rod that responds to the movement of the shift lever is disposed coaxially with the steering column, and a pointer moves in response to the movement of the control rod, which instructs the indicator. , the shift position can be displayed in front of the steering wheel.

[Problem that the invention attempts to solve]

However, in a steering wheel shift mechanism in which the control rod and steering column are arranged coaxially, the arrangement structure is complicated due to the relationship with the steering shaft, and maintenance and inspections are time-consuming. There is a request to move the door to the side of the steering shaft.

Based on the above-mentioned requirements, the present invention has been developed to ensure that even in vehicles (not limited to automatic vehicles) where the control rod is placed on the side of the steering column,
Equipped with a shift position display device that can display the shift position in front of the steering wheel, the control rod can be assembled to the desired position on the steering column with high precision, and the movement of the control rod can be monitored by the shift position display device. To provide a handle shift mechanism with a shift position display device, which is equipped with a link mechanism capable of accurately and reliably transmitting information without adversely affecting the operation feeling during shift change of an automatic transmission.

It is a perspective view of the snap spring for the shift position indicating member.

As shown in Figs. 1 to 3, in this steering wheel shift mechanism, a control rod is attached to the side of the steering column 1 which rotatably supports a steering shaft 26 having a steering wheel (not shown) attached to its upper end. 2 are arranged. This control rod 2 is composed of a pipe member with one end open and the other end closed, and a pin 4 biased outwardly by a spring 3 is fitted into the open end, as shown in FIGS. 1 and 6. This pin 4 is rotatably supported by a bracket 5 attached to the steering column 1, and the other end of the control rod 2 is attached to another bracket 6 attached to the steering column 1, as shown in FIGS. is rotatably supported. A rubber stopper 15 is attached to the other end surface of the control rod 2.

Further, a shift lever mounting cylinder 2a is provided on the control rod 2 and projects laterally, and a shift lever 7 is mounted on this shift lever mounting cylinder 2a. As shown in FIG. 6, the shift lever 7 is mounted so as to be able to swing in the X and Y directions about a fulcrum member 8 in the shift lever mounting cylinder 2a, and as the shift lever 7 swings, the fulcrum member 8
The extension member 9 extending from the shift lever mounting cylinder 2a and engaging with the hole 4a with the bracket 5 also swings.
As a result, the control rod 2 also slides in the axial direction and rotates around the axis.

As shown in FIGS. 1 and 7, the control rod 2 is provided with a protruding pin 10 that can engage with a detent plate 6a with a bracket 6, and when the control rod 2 slides and rotates, The detent plate 6a and the pin 10 can be engaged and disengaged.

Further, a first lever 11 is provided on the control rod 2 and protrudes laterally.
The cable 1 is connected to the cable 1 via the first link mechanism 12 (hereinafter also simply referred to as the "link mechanism 12").
3 are connected. This cable 13 is connected to the manual valve side of the automatic transmission. Note that the cable 13 is the outer cable 1
4, one end of the outer cable 14 is fixed to the bracket 6.

By the way, as shown in FIGS. 1, 2, 3, and 5, a ring-shaped shift position indicating member 17 with a pointer 16 as a shift position indicating member is provided on the outer periphery of the steering column 1 closer to the handle than the mounting position of the bracket 5. is rotatably fitted, and this ring-shaped shift position indicating member 17
One end surface is in sliding contact with the bracket 5, and the other end surface is attached to the steering column 1 via a wave washer 18 and a washer 19 with a snap ring 20 as shown in FIG.

As shown in Figures 1, 2 and 4, an indicator 21 with shift position marks (L, 2, D, N, R, P) is attached to the bracket 5 attached to the steering column 1. The shift position indicating member 17 rotates and the pointer 1
6, the pointer 16 sequentially indicates the shift position mark on the indicator 21 accordingly.

Further, as shown in FIGS. 1 to 3 and 5, a second link mechanism (hereinafter simply "link mechanism 2") is provided between the control rod 2 and the shift position indicating member 17.
2) is interposed. This link mechanism 22 includes a second lever 22a whose base end is attached to the control rod 2, and one end which is pivotally attached to the tip of this lever 22a via a rubber member 23 for absorbing select movement, and the other end which is connected to the select movement absorber. A link member 22b is pivotally connected to the shift position indicating member 17 via another rubber member 24 for absorbing movement.

Note that similar rubber members for absorbing select movement are provided at each link pivot portion of the link mechanism 12, and the select movement absorbed by these rubber members 23 and 24 is about 5°.

With the above configuration, to perform a shift operation,
The shift lever 7 can be moved in the Y direction (or in the X direction if necessary), but the cable 13 is actuated in response to the movement of the shift lever 7, and a manual valve (not shown) is actuated to achieve the desired shift position. I can do it. At this time, the link mechanism 22 also operates in accordance with the movement of the shift lever 7, and the shift position indicating member 17 rotates by a predetermined amount. As a result, the guideline 16
The pointer 16 points to the desired shift position mark on the indicator 21. As a result, the shift position is displayed.

At this time, the control rod 2 is connected to a pair of brackets 5 and 6 provided on the steering column 1.
Because of the structure in which the control rod 2 is rotatably held in the steering column 1, it is possible to assemble the control rod 2 at a desired position on the steering column 1 with high precision, resulting in a stable product without poor operability caused by assembly errors. It will be done.

Furthermore, control rod 2 (first lever 1
