Description

[Detailed description of the invention] The present invention relates to a remote control device for an automobile transmission that operates in the select direction and shift direction by moving the fork operating shaft in the axial direction and rotating around the shaft center. In particular, the present invention relates to a device using a control cable, in which an inner cable is slidably inserted into an outer tube, as an operating force transmission member.

For example, as in the case of a front-wheel drive vehicle shown in Fig. 1, when the transmission T is located away from the operating lever L and remote control is performed, the inner cable B can be freely slid into the outer tube A as an operating force transmission member. The inserted control cable C is attracting attention as an alternative to the conventional connection rod, but when such a control cable C is used, there is a structure that does not previously exist for connecting it to the fork operating shaft S protruding from the transmission T. A new problem is emerging.

That is, as illustrated in FIG. 1, a fork operating shaft S protrudes rearward from a transmission T provided on the side end surface of an engine E placed horizontally in the front part of the vehicle body, and a fork operating shaft S provided approximately in the center of the vehicle body. control lever L
When connecting them with a control cable C ₁ for select operation and a control cable C ₂ for shift operation bent in a substantially L shape,
If the radius of curvature of the bent part is made smaller, the sliding resistance of the inner cable B against the outer tube A will increase and the operating force transmission efficiency will decrease. It is necessary to increase the radius of curvature by moving the fork closer together, but if you do this, when the fork operating shaft S moves in the axial direction due to the operation of the control cable C ₁ for select operation, the control cable C for shift operation The horizontal swing angle of Rod R ₂ , which connects ₂ and fork operating shaft S, becomes excessive, and the control cable
There is a disadvantage that extra force acts on the terminal portion of C ₂ , reducing durability and operational force transmission efficiency.

The present invention eliminates such drawbacks, increases the radius of curvature of the bending part of the control cable as much as possible, and increases the swing angle of the rod that connects the control cable for shift operation and the fork operation shaft as much as possible. The object of the present invention is to provide a remote control device for an automobile transmission that is small in size.

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

The fork operating shaft S that protrudes rearward of the transmission T has a pair of flanges 1, 1 protruding from its outer periphery at intervals, and protrudes upward at its tip and is bent in the opposite direction to the mounting plate P. A lever 2 is fixed, and a swinging body 5 is attached to a bracket 3 projecting from the frame above the fork operating shaft S by a shaft 4 so as to be freely swingable in the horizontal direction.
This rocking body 5 has a first arm 7 that projects rearward from the upper end of a cylindrical portion 6 that fits into the shaft 4, and a second arm 7 that is approximately L-shaped and that projects laterally and is bent downward at the lower end.
An arm 8 is formed, and a lower end portion of the second arm 8 is fitted substantially tightly between the pair of flanges 1, 1 formed on the outer periphery of the fork operating rod S.

The terminal end of the outer tube A ₂ of the control cable C ₂ for shift operation is passed through the groove 10 on the lower side of the mounting plate P fixed to the frame and fixed by tightening with a nut 12, as shown in detail in FIG. The sleeve 16 is fitted into an enlarged diameter hole 13 formed at one end of the hub 11 and fixed by caulking, and the spherical head 17 of the sleeve 16 is fitted into a spherical hole 15 formed at the other end of the hub 11. The rod _R2 is freely slidably supported in the center hole 18 of the sleeve 16, and the control cable _C2 protrudes into the sleeve 16 through the center hole 14 of the hub 11. Inner cable _B2 is connected to this rod _R2 . A female member 19 of a ball joint 21 having a spherical hole 20 is connected to this rod R ₂ , and a male member 28 of the ball joint 21 having a spherical head 22 that fits into the spherical hole 20 is connected to the rod R 2 . fixed at the end.

The outer tube A ₁ of the control cable C ₁ for selection operation is fixed to a hub 24 having substantially the same configuration as the hub 11 fixed to the groove 9 on the upper side of the mounting plate P, and the inner cable B ₁ is fixed to the hub 24
The rod _R1 is connected to the pin ₂ , which is supported so as to be freely swingable and axially movable.
5 is connected to the tip of the first arm 7 of the swinging member 5.

Next, to explain the operation of this embodiment, as the operating lever L swings in the left-right direction, the inner cable _B1 of the control cable _C1 for selection operation slides within the outer tube _A1 , and is connected via the rod _R1. The oscillating body 5 connected to the inner cable B ₁ is connected to the shaft 4.
When the second arm 8 and the collars 1, 1 are engaged with each other, the fork operating shaft S moves in the axial direction, and the fork operating shaft S is moved in the axial direction by swinging the operating lever L in the front-rear direction. Inner cable B ₂ of control cable C ₂ is connected to outer tube A ₂
Sliding inside, rod R ₂ and ball joint 2
The fork operating shaft S rotates about its axis together with the lever 2 connected to the inner cable B ₂ via the lever ₂ . moves in the axial direction, the rod R ₂ engages the spherical head 17 of the sleeve 16, as shown in FIG.
This causes a swinging motion in the horizontal direction around the center. However, in this embodiment, since the tip of the lever 2 bent in the opposite direction to the hub 11 is connected to the rod _R2 , the fork operation shaft S is The swing angle of the rod _R2 with respect to the axial movement of the rod R2 becomes smaller.

As specifically explained in the above embodiment,
The remote control device for an automobile transmission of the present invention operates by moving the fork operating shaft in the axial direction and rotating the fork operating shaft around the axis. In a remote control device for an automobile transmission, in which power is transmitted by a control cable having an inner cable slidably inserted into an outer tube, the control cable is arranged substantially perpendicularly to the fork operating shaft and at a distance. The terminal of the outer tube is fixed to the hub provided, the terminal of the inner cable is fixed to a rod attached to the hub so that it can move freely in the axial direction and swing freely, and the terminal is fixed to the fork operating shaft opposite to the hub. The gist is that a lever protruding in the direction is fixed, and the lever and the tip of the rod are connected via a ball joint, and the distance from the center of swing of the rod to the connection point with the lever is Because it is long, the swing angle of the rod with respect to the axial movement of the fork operating shaft is small, and the pushing and pulling force of the inner cable is easily converted into the rotational force of the fork operating shaft, improving the efficiency of operating force transmission and the durability of parts. It has the effect of improving
