Description

[Detailed explanation of the invention] A. Purpose of the invention (1) Industrial application field This invention is based on the invention by connecting one end of a push-pull operating wire to the gear shift lever and connecting the other end of the push-pull operating wire to the side of the tip of the shift lever of the transmission. This invention relates to an improvement in a wire-type change mechanism connected to a protruding connecting pin.

(2) Prior art This type of change mechanism is, for example,
This is already known as described in Publication No. 45418.

(3) Problems to be solved by the invention Generally, the operating load on the shift lever of a transmission varies during one operating stroke, as shown by line A in Fig. 2. The frictional resistance between the outer wire and the inner wire of the push-pull type operation wire is added to the operating load of the shift lever, and the shift operating load of the gear change lever fluctuates greatly as shown by line B in Fig. 2, so the shift operation feeling changes. It has the disadvantage of impairing the

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide the above-mentioned change mechanism that has less variation in the shift operation load on the gear shift lever and has a good shift operation feel.

B. Structure of the invention (1) Means for solving the problem In order to achieve the above object, the invention is characterized in that a weight is attached to the side of the tip of the shift lever opposite to the connecting pin. do.

(2) Effect According to the above configuration, a large moment of inertia around the rotation axis of the shift lever can be applied to the shift lever using a relatively small weight, and the inertial effect affects the light selection operation. It is possible to reduce fluctuations in the shift operation load of the speed change lever without causing any adverse effects.

Furthermore, since the weight is attached to the side surface of the shift lever opposite to the connecting pin, the amount of overhang from the shift lever can be minimized.

(3) Embodiment Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. In FIG. are mutually orthogonal select directions
It is rotatably supported in the Se and shift directions Sh.
In addition, the prop 2 has a gear shift lever 3 in the select direction.
An interlocking lever 4 that rotates in a direction perpendicular to the selection direction Se in conjunction with the rotation of Se is pivotally supported.

The speed change lever 3 and the interlocking lever 4 are provided with connecting pins 5 and 6 protruding from one side of each lower end.

On the other hand, a select lever 8 and a shift lever 9 are rotatably supported on the outer wall of the transmission case 7 of the transmission M. The select lever 8 and the shift lever 9 have connecting pins 10 and 11 protruding from one side of each tip, and the connecting pin 11 of the select lever 8 and the connecting pin 6 of the interlocking lever 4 are connected to the operating wire. 12, the connecting pin 10 of the shift lever 9 and the connecting pin 5 of the speed change lever 3 are connected to each other by an operating wire 13, respectively.

Each operating wire 12, 13 is configured in a push-pull type. That is, tube-shaped outer wires 14, 15 and inner wires 16, 17 slidably inserted into the outer wires 14, 15.
Both ends of each outer wire 14, 15 are fixed to the vehicle body side, and both ends of one inner wire 16 are connected to connecting pins 6, 11, respectively.
Both ends of the other inner wire 17 are connected to the connecting pin 5,
10 respectively.

In such a change mechanism, a weight 18 is attached to the side surface of the tip of the shift lever 9 opposite to the connecting pin 10 by welding or other fixing means.

Next, the operation of this embodiment will be explained. First, when the gear shift lever 3 is rotated in the select direction Se, the interlocking lever 4 rotates and pulls or pushes the inner wire 16 of the operating wire 12, thereby selecting the select direction. Lever 8 rotates to select a desired gear train of transmission M. Next, when the shift lever 3 is rotated in the shift direction Sh, the lever 3 directly pulls or pushes the inner wire 17 of the operating wire 13, thereby rotating the shift lever 9 and shifting the previously selected gear. Establish a column.

By the way, the shift lever 9 is given a large moment of inertia around the rotation axis by the weight 18 attached to its tip, so due to the inertia effect, the operating load of the shift lever 9 fluctuates as shown in Fig. 2. It decreases like line C. Therefore, fluctuations in the shift operation load of the gear change lever 3 are also small as shown by line D in FIG. 2, and a good shift feeling can be given to the operator. In particular, since the weight 18 is attached to the tip of the shift lever 9, it is possible to give a large moment of inertia to the shift lever 9 even if the weight is small.

Further, since the weight 18 is attached to the side surface of the shift lever 9 opposite to the connecting pin 10, the amount of overhang from the shift lever 9 is minimized, and due to the inertia of the weight 18, the shift lever 9 It is possible to suppress the torsional load generated in the

Furthermore, the shift lever 3, which generally has a small operating load,
When selecting the shift lever 9, the weight 1 of the shift lever 9
8 has no effect at all, so the light selection operation is not impaired in any way.

C. Effects of the invention As described above, according to the invention, since a weight is attached to the side of the tip of the shift lever opposite to the connecting pin, the relatively small weight allows the shift lever to be attached to its rotation axis. It is possible to provide a large moment of inertia to the surroundings, and due to this inertia effect, it reduces fluctuations in the shift operation load of the gear shift lever without affecting the light selection operation, improving the operation feeling. be able to.

Moreover, since the weight is attached to the side opposite to the connection pin of the shift lever, the amount of overhang from the shift lever is minimized, and the torsional load on the shift lever caused by the inertia of this weight is kept to a minimum. The area around the lever can be made more compact.
