Description

[Detailed Description of the Invention] The present invention relates to an improvement of a parking cable support device.

A conventional parking cable support device is explained with reference to FIG. 1. A is a bracket fixed to the rear axle housing b, c is a cable clip fixed to the bracket b, and d is a lift C.
f is the parking cable, e is the rubber wrapped around the parking cable f, and the parking cable f is attached to the rubber e pipe d grip C bracket b
It is fixed to the rear axle housing a via.

Since the rear axle housing a is unsprung, it vibrates when the wheels move up and down due to unevenness of the road surface while the car is running.In the parking cable support device, the parking cable f is attached to the rubber e Vibe d Grip C is fixed to the rear axle housing a via the bracket b, and the movement of the rear axle housing a is directly transmitted to the parking cable f, which is connected to the parking cable f along with the rear axle housing a in the longitudinal direction A of the parking cable f. and is displaced in the circumferential direction B of the parking cable f.

The compression side of the parking cable f is connected to a brake lever provided on the vehicle body, and the right end side of the parking cable f is connected to a parking brake device.
Neither displacement in the longitudinal direction A nor displacement in the circumferential direction B is allowed.

Therefore, the parking cable f is pulled or bent due to the displacement in the longitudinal direction A at the fixed part e-1), and due to the displacement in the circumferential direction B at the fixed parts e-1),
There was a problem in that the parking cable f and the cable clip C were damaged early due to the twisting.

This proposal addresses the above-mentioned problems, and consists of a parking cable that transmits the operating force of a brake lever installed on the vehicle body to the parking brake device, a bearing fixed to the outer circumferential surface of the parking cable, and a bearing that is pivotally supported on the wheel side member. A cable clip that slidably supported the same bearing.
The purpose of this invention is to provide an improved parking cable that can improve the durability of the parking cable and cable clip. The point is that it provides a support device.

In the parking cable support device of this invention, a cable clip having a pipe is rotatably attached to a bracket fixed to a wheel side member as described above, a bearing is fixed to the outer peripheral surface of the parking cable, and the bearing is slid into the pipe. Since the bearing is inserted freely and grease is filled between the bearing and the pipe, when the wheel moves up and down due to unevenness of the road surface while the car is running, the wheel side member When the wheel side member is displaced in the horizontal direction, the bearing slides in the length direction of the parking cable against the pipe, and the cable clip swings in the length direction of the parking cable against the bracket, allowing the wheel side member to easily move. Absorbs smoothly.

Furthermore, when the wheel-side member is displaced in the circumferential direction of the parking cable, the bearing slides relative to the pipe in the circumferential direction of the parking cable, thereby absorbing the displacement of the wheel-side member effortlessly and smoothly.

Therefore, there is no need to apply excessive force to the parking cable or cable clip, and there is no risk of damage to the parking cable or cable clip, thereby improving their durability.

Next, the parking cable support device of the present invention will be explained with reference to an embodiment shown in FIGS. 2 to 4. 1 is a rear axle housing, 2 is a bracket attached to the rear axle housing 1, 6 is a cable clip, and 5 is a rear axle housing. , 5 is a resin washer interposed between the cable clip 6 and the bracket 2, 3 is a clevis pin to which the cable clip 6 and the bracket 2 are rotatably attached, 4
is a split pin inserted into the clevis pin 3, 7 is a pipe fixed to the upper end of the cable clip 6, 9 is a parking cable, 8 is a bearing fixed on the parking cable 9, and the bearing 8 is connected to the pipe 7.
Grease is filled between the bearing 8 and the pipe 7.

Further, 10.10 is a boot for preventing guest intrusion, one end of which is fitted onto the pipe 7 and the other end of which is fitted onto the parking cable 9, and 11 is a rear caliper brake operated by the parking cable 9.

The parking cable support device of the present invention rotatably attaches the cable clip 6 having the pipe 7 to the bracket 2 fixed to the rear axle nozzle 1 as described above, fixes the bearing 8 to the outer peripheral surface of the parking cable 9, and fixes the bearing 8 to the outer peripheral surface of the parking cable 9. Since the bearing 8 is slidably inserted into the pipe γ and grease is filled between the bearing 8 and the pipe 7, the wheels do not move up and down due to irregularities in the road surface while the car is running. Therefore, when the rear axle housing 1 is displaced in the longitudinal direction A of the parking cable 9, the bearing 8 slides in the longitudinal direction A of the parking cable 9 with respect to the pipe 7, and the cable clip 6 is parked around the clevis pin 3. The cable 9 swings in the direction A along the length 71i, and the displacement of the rear axle housing 1 is easily and smoothly absorbed.

Also, the rear axle housing 1 is connected to the parking cable 9.
When the rear axle housing 1 is displaced in the circumferential direction B, the bearing 8 slides in the circumferential direction B of the parking cable 90 relative to the pipe 7, and absorbs the displacement of the rear axle housing 1 smoothly and effortlessly.

Therefore, there is no need to apply excessive force to the parking cable 9 or the cable clip 6, and there is no fear of damage, and the durability of these can be improved.
