Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a relay lever device used for remote control of a vehicle transmission.

(Prior art) Remote control of the transmission converts the driver's gear shift operation into displacement of the control rod in both rotational and thrust directions, and transmits these two types of displacement to the transmission via a relay lever device. This is done by An example of this relay lever device is a cross-shaft type relay lever device as shown in FIG. That is, two outer cylinders 3A and 3B are arranged in parallel and rotatably attached around a fixed shaft 14 fixed to the vehicle body, and one of the outer cylinders 3A is inserted, and output shift levers 11A and 11B are fixed. Then, it enters the other outer cylinder 3B and fixes the output select levers 9A and 9B. The input shift lever 11A and the input select lever 9A rotate in conjunction with displacement of a control rod (not shown) in the rotational direction and thrust direction by the driver's gear shift operation, respectively, and the output lever rotates integrally with these. shift lever 11B
and an output select lever 9B transmit operating force to the transmission via rods (not shown) to switch gears.

However, in this relay lever device, the shift lever outer cylinder 3A and the select lever outer cylinder 3B are arranged in parallel on the rotating shaft, so the shift levers 11A and 11B and the select lever 9A For example, if the shift levers 11A and 11B are arranged inside the select levers 9A and 9B, a similar layout cannot be achieved, and the setting of the lever spacing between the input side and output side is also restricted. However, there are many inconveniences when constructing a remote control mechanism.

On the other hand, a relay lever device as shown in FIG. 4 has been proposed in order to increase the degree of freedom in the arrangement and spacing of the levers (for example, Utility Model Application No. 59-145425). This structure includes an outer cylinder 3, which is also freely rotatable, around a rotary shaft 16 that is rotatably attached to the vehicle body via a ball bearing 15, and a select system lever 9A is attached to the protruding portion of the rotary shaft 16 to both ends of the outer cylinder 3. and 9B, respectively, and shift levers 11A and 11B are fixed on the outer cylinder 3 at a predetermined interval. In this relay lever device, the shift levers 11A and 11B are the select lever 9A.
and 9B, and the lever interval can be freely set by changing the lengths of the rotating shaft 16 and the outer cylinder 3.

(Problems to be Solved by the Invention) In this device, since both the rotating shaft 16 and the outer cylinder 3 rotate, the rotating shaft 16 is supported by a ball bearing 15. but,
This makes it difficult to center the brackets 5A and 5B that hold the ball bearings 15 when attaching the relay lever device to the vehicle body, and the use of the ball bearings 15 complicates the device, which requires additional manufacturing and assembly time. There was a problem with high costs.

In view of the above-mentioned problems regarding relay lever devices, the present invention aims to realize a relay lever device with a simple structure that allows a high degree of freedom in setting the arrangement and spacing of levers.

(Means for solving the problem) In the present invention, in a relay lever device used for remote control of a transmission, a hollow shaft whose both ends are fixed to the vehicle body via a bracket, and an outer periphery of the hollow shaft are provided. An outer cylinder that is rotatably supported on a surface and shorter than the hollow shaft is provided, and a middle shaft that is rotatably supported on the inner peripheral surface of the hollow shaft and longer than the hollow shaft is provided. An input lever and an output lever of either a shift system or a select system are fixed to the outer peripheral surface of the outer cylinder so as to be located between the two brackets, and the input lever and output lever of the other one are fixed to the outer peripheral surface of the outer cylinder so as to be located between the two brackets. Attach it to both ends of the center shaft so that it is located on the outside.

(Function) Since the outer cylinder supported on the outer peripheral surface of the hollow shaft fixed to the vehicle body and the center shaft supported on the inner peripheral surface are used as rotation transmission members, rotation support members such as ball bearings are not required, and the outer cylinder is By changing the lever attachment position to the cylinder and the length of the center shaft, the arrangement and spacing of the levers can be set as desired.

(Example) An embodiment of the present invention is shown in FIGS. 1 and 2.

Reference numeral 1 denotes a relay lever device, in which an outer cylinder 3 is attached to the outside of a hollow shaft 2, and a center shaft 4 is rotatably attached to the inside. The hollow shaft 2 has an end 2B welded to a bracket 5B fixed to the vehicle body, and the other end 2A
is slidably penetrated in the axial direction through the hole 6 of the bracket 5A, which is similarly fixed to the vehicle body. The outer cylinder 3 is rotatably attached to the outer peripheral surface of the hollow shaft 2 between the brackets 5A and 5B via a bush 7. 8 is a C ring that restricts the movement of the bush 7 in the axial direction. Input side and output side select levers 9A and 9B are fixed to the outer periphery of the outer cylinder 3 at predetermined intervals and rotation angles. The center shaft 4 is a solid shaft that is longer than the hollow shaft 2, passes through the inside of the hollow shaft 2, projects on both sides, and is rotatably supported by the bush 10. An output side shift lever 11B is welded to one end 4B protruding from the hollow shaft 2, and an input side shift lever 11A is fixed to the other end 4A protruding from the opposite side. To fix this, as shown in FIG.
and bolt 13A and nut 13.
Tighten hole 12 with B. Note that when installing the relay lever device 1 to the vehicle body, first attach the hollow shaft 2.
After fixing the welded bracket 5B to the vehicle body and attaching the outer cylinder 3 and C ring 8 to the hollow shaft 2 in this order from the end 2B side, insert the hole 6 of the bracket 5A into the end 2A.
to secure the bracket 5A to the vehicle body.
Next, insert the center shaft 4 to which the output side shift lever 11B is welded into the hollow shaft 2 from the end 2B side, and fix the input side shift lever 11A to the end 4A protruding from the hollow shaft 2 using the above method. do.

Next, the action will be explained.

In this relay lever device 1, the select levers 9A and 9B may be welded to arbitrary positions on the outer cylinder 3, and the shift levers 11A and 11B may be welded to the center shaft 4.
By changing the length of the lever 11A and changing the mounting angle of the lever 11A, the levers can be fixed at arbitrary intervals and angles. The bracket 5A is movable in the axial direction on the hollow shaft 4 within the range sandwiched between the shift lever 11B and the C ring 8, and even if there is some error in the mounting dimensions between the vehicle body side and the device 1, this movement allows the bracket 5A to move in the axial direction. Errors can be absorbed. In addition, since the rotation of the outer cylinder 3 and the inner shaft 4 is supported by the bushes 7 and 10 on the outside and inside of the hollow shaft 2, respectively, there is no need for complicated rotation support members such as ball bearings, and the relay lever device 1 is compact. It fits in. Note that the select levers 9A and 9B are located inside the shift levers 11A and 11B, but due to the configuration of the operating mechanism,
The arrangement of these levers may be reversed.

(Effects of the invention) As described above, the relay lever device of the invention uses the rotatable outer cylinder and the inner shaft, which are supported respectively on the outer and inner peripheral surfaces of a hollow shaft fixed to the vehicle body, as rotation transmitting members. By changing the lever mounting position on the outer cylinder and the length of the center shaft, the lever arrangement and spacing can be freely set without the need for bending, etc., as well as the ball bearing that supports the rotation transmission member and the boot that holds it. The structure is simple and the device itself is compact because it does not require Therefore, the cost required for manufacturing and assembling the relay lever device can be reduced, and the layout of the lever can be matched to the configuration of the transmission and control rod, making it easier to design the entire remote control mechanism. become.

In addition, since the present invention has a structure in which the hollow shaft is supported on the vehicle body via brackets at both ends, it is possible to ensure sufficient length of the bearing part for the central shaft and outer cylinder, realizing smooth movement, and also to realize smooth movement of the relay lever. Since the supporting rigidity of the device can be increased, it is also possible to improve the operability in remote control.
