Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a remote control operating mechanism for an automobile transmission.

BACKGROUND ART A typical remote control operation mechanism of this type has a structure shown in FIG. 5 (for example, Japanese Patent Publication No. 34886/1986). As shown in the figure, the displacement of the change lever 1 in the shift direction and the select direction is transmitted to the upper shift rod 4 and the upper select rod 5 via the control rod 3 provided on the steering column 2. do. This displacement is further transmitted from the cross shaft 6 to the shift lever 10 and select lever 11 on the transmission 9 side via the lower shift rod 7 and lower select rod 8,
Thereby, the gear change mechanism of the transmission 9 is operated.

Problems to be solved by the invention In the conventional operation mechanism shown in Fig. 5, not only is it not possible to obtain a large lever ratio due to layout constraints, but also the conversion mainly using the bell crank 12, lever 13, etc. Since the number of parts after the mechanism section 14 is large and the structure is complicated, it is likely to be disadvantageous in terms of space efficiency.

The present invention aims to provide an operating mechanism with a large lever ratio and a simple structure in place of the above-mentioned operating mechanism.

Means for Solving the Problems The present invention provides a conversion mechanism mainly consisting of a bell crank or the like in the part near the steering column, that is, the base where the change lever is attached.
The bell crank and change lever are connected to each wire cable of the displacement transmission system on the transmission side at a position opposite to the rotation fulcrum by crossing the steering column.

More specifically, the remote control operating mechanism of the present invention is supported rotatably in the shift and select directions by a fulcrum on one side of the upper end of the steering column, and the end on the operating unit side supports the steering column. a change lever extending across and in the vehicle width direction on the side opposite to the fulcrum part, one end of which is connected to the end of the change lever on the fulcrum part side and rotates in response to a shift operation of the change lever; a bell crank whose other end extends across the steering column in the vehicle width direction on the opposite side of the fulcrum; one end is connected to the bell crank, and the other end is connected to a shift lever on the transmission side. and a wire cable whose one end is connected to a position of the change lever closer to the operation part than the fulcrum part, and whose other end is connected to a selection lever on the transmission side.

Effects According to the present invention, since the conversion mechanism such as a bell crank is located at the base of the change lever, there is no restriction on the lever ratio and the structure is extremely simple.

Embodiment FIGS. 1 to 4 are diagrams showing a more specific embodiment of the present invention.

As shown in FIGS. 1 to 4, a bracket 21 including a housing 20 is fixed to one side of the upper end of the steering column 2, and a ball joint 2 serving as a fulcrum is fixed to the bracket 21.
2, a change lever 23 is supported so as to be rotatable in the shift direction and the select direction.
In FIG. 3, 24 is a bushing interposed between the housing 20 and the bracket 21, 25 and 26 are collars, and 27 is a coil spring.

The end of the change lever 23, to which the operating knob 23b is attached, on the operating section side crosses the lower part of the steering column 2, and extends across the steering column 2 to the opposite side from the fulcrum section. (See Figure 4).

Here, since the change lever 23 crosses the steering column 2 as shown in FIG. 4, the dimension between the lower surface of the steering column 2 and the change lever 23 is By setting it in accordance with the shift direction stroke of the lever 23, it can be used as a stopper that restricts the upward stroke of the change lever 23 in the shift direction. in this case,
Steering column 2 side or change lever 2
It is desirable to attach an elastic body such as rubber to the third side to prevent hitting sounds.

A bell crank 29 is rotatably supported on the bracket 21 via a pin 28. The bell crank 29 crosses the upper part of the steering column 2, and extends in the same direction as the change lever 23, with the steering column 2 sandwiched between the bell crank 29 and the change lever 23. One end 29a of the bell crank 29 located on the bracket 21 side is connected to a tip 23a of the change lever 23 on the fulcrum side.

Push-pull cables 30 and 31 as wire cables are connected to the change lever 23 and the bell crank 29, respectively. More specifically, one end 30a of the inner wire 30A of one push-pull cable 30 is connected to a position 23c of the change lever 23 that is closer to the operation knob 23b, which is the operation part, than the ball joint 22, which is the rotation center fulcrum. The other end 30b is connected to the select lever 11 on the transmission 9 side.

Similarly, the other end 29b of the bell crank 29
One end 31a of the inner wire 31A of the other push-pull cable 31 is connected to the
The other end 31b is also connected to the shift lever 10 on the transmission 9 side. The outer tubes 30B, 31B of the push-pull cables 30, 31 are fixed to brackets 32, 33 on the steering column 2 side and brackets 34, 35 on the transmission 9 side, respectively.

Therefore, according to the above configuration, during a shift operation, the bell crank 29 rotates around the pin 28 due to the displacement of the change lever 23, and as a result, the inner wire 31A of the push-pull cable 31 is pressed or pulled, and as a result, the shift lever 10 rotates.
As a result, the gear transmission mechanism in the transmission 9 is operated to change gears.

Also, when selecting, the bell crank 29
As a result, only the change lever 23 rotates independently without any displacement, and the inner wire 30A of the push-pull cable 30 is pushed or pulled.
The select lever 11 rotates. As a result, the gear transmission mechanism within the transmission 9 is selectively switched.

Effects of the invention As described above, according to the invention, a conversion mechanism mainly including a bell crank is provided on the upper end side of the steering column, and the bell crank and the change lever are made to cross the steering column and serve as a pivot point. By connecting each wire cable in the opposite position, the lever ratio can be increased, and the displacement transmission system from the above conversion mechanism to the transmission requires only the wire cable, reducing the number of parts. The structure can be simplified, which is advantageous in terms of space efficiency.
