Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a cable-type remote control device for a transmission, and more particularly to a technique for improving a feeling of operating a gear shift lever during a shift operation.

<Prior Art> In vehicles such as buses and cab-over vehicles, where the gear shift lever and the transmission are separated from each other in the driver's cab, the gear shift lever cannot be directly connected to the gear shift operation member on the transmission side. The remote control system is adopted for the gear shifting operation.

As such a remote control system, there is a cable system in which a gear shift lever and a gear shift operating member on the transmission side are connected via a cable. This has the advantages that the layout is easy, the weight is low, the cost is low, and the number of parts is small, as compared with the rod system in which a plurality of rods are connected.

<Problems to be solved by the invention> However, in the case of the cable system, since the mass of the movable portion that moves with the shift operation of the gear shift lever is small, when the gear shift lever is shifted,
The initial operation force was too light and the feeling of entering the two gears was easily transmitted to the hand, and the operation feeling of the gear shift lever was not good.

As a cable type gear shift operation device for a transmission, there is one disclosed in, for example, Japanese Utility Model Laid-Open No. 1-120226.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cable-type remote control device for a transmission, which can reduce a feeling of entering two gears during a gear shift operation and has a good feeling of operating a gear shift lever.

<Means for Solving the Problem> Therefore, the present invention includes a gear shift lever provided in the driver's cab and a gear shift operation member provided on the transmission side for performing gear shift operation of the transmission in conjunction with the operation of the gear shift lever. In the cable type remote control device of the transmission connected via the cable,
A gear shift operation member that is rotated by a shift operation of the gear shift lever extends in the vehicle left-right direction from the transmission, and a horizontal member that extends in the vehicle front-rear direction is attached to the gear shift operation member. The weights are provided at symmetrical positions in the front-rear direction.

<Operation> In this configuration, when the gear shift lever is operated to shift, the gear shift operation member is rotated via the cable, and the horizontal member and the weight are rotated integrally with the gear shift operation member. For this reason, in the initial operation of the gear shift lever, an operation force for moving the horizontal member and the weight is required in addition to the gear shift operation member, and the initial operation force of the gear shift lever can be increased, so that the driver can feel the two-step entering directly. Can be reduced.

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

In the drawings showing the present embodiment, a gear shift lever 1 provided in a driver's cab is supported by a fulcrum 2 so as to be swingable in the left-right and front-rear directions of the vehicle. A lower end portion of the gear shift lever 1 is connected via a cable 5 to an outer lever 4 of a transmission body 3 which is arranged rearward of a driver's cab. The outer lever 4 is attached to a cross shaft 8 extending in the vehicle left-right direction, one end of which is pivotally supported by a vehicle body frame (not shown) and the other end of which is connected to an inner shaft 7 via a universal yoke 6. The universal yoke 6 is for absorbing relative movement between the frame side and the transmission side. A shift lever on the transmission side is spline-fitted to the inner shaft 7 in a remote control cover 9 provided on the upper portion of the transmission body 3, and the shift lever is moved in the axial direction of the inner shaft 7 by a select operation system (not shown). To move to. Then, the inner shaft 7, the cross shaft 8, the shift lever, and the like constitute a transmission-side gear shifting operation member.

In the present embodiment, in addition to the above-described conventional configuration, a weight mounting bracket 10 as a horizontal member extending in the vehicle front-rear direction at a right angle to the cross shaft 8 is attached to the cross shaft 8. Disc-shaped weights 11, 11 are provided at positions symmetrical with respect to the cross shaft 8 of the weight mounting bracket 10 in the vehicle front-rear direction.

In such a configuration, when the gear shift lever 1 is selected in the left-right direction of the vehicle, a select operation system (not shown) moves to the position of the shift fork or shifter at which the shift lever on the transmission side tries to shift in the axial direction of the inner shaft 7. Moving. Next, when the gear shift lever 1 is shifted in the vehicle front-rear direction, the outer lever 4 and the cross shaft 8 and the inner shaft 7 are integrally rotated via the cable 5, and the shaft fork or shifter is moved via the shift lever to obtain a desired value. The shift operation is performed to the shift stage.

In the above shift operation, the weight mounting bracket 10 and the weights 11 and 11 are also rotated integrally with the cross shaft 8 during the shift operation of the gear shift lever 1, so that the shift operation system includes the weights 11 and 11 and the weight mounting bracket 10. It becomes heavy by the mass of. Therefore, the initial operation force of the gear shift lever 1 becomes heavier than before, and the feeling of entering two gears during a shift operation is reduced as compared with the prior art, and the shift operation feeling can be improved. Further, since the weights 11 and 11 are provided at symmetrical positions of the weight mounting bracket 10, there is no fear that the balance of the shift operation system will be lost.

<Effect of Device> As described above, according to the present invention, the mass of the shift operation system in the cable type remote operation device having a small mass can be increased without impairing the operational stability, and the initial operation force during the shift operation can be increased. Since it becomes heavier, it can reduce the feeling of entering two steps. Therefore, the shift operation feeling of the cable type remote control device can be improved.
