Description

Technical Field

[0001] The utility model relates to the technical field related to floating calipers, in particular to a shock-absorbing floating caliper pin shaft. Background Art

[0002] The floating caliper only has a piston structure on one side. It is called floating because the caliper body can be displaced in the axial direction along the guide pin relative to the bracket. When braking, the inner piston pushes the inner friction pad to contact the brake disc first. As the brake fluid continues to be filled, the contact force between the inner friction pad and the brake disc continues to increase. The reaction force will pull the caliper body to move along the guide pin, allowing the outer brake pad to contact the brake disc and then clamp it, ultimately achieving braking. However, when braking, the caliper and the pin will collide. Therefore, a shock-absorbing floating caliper pin is particularly needed.

[0003] However, the existing floating caliper pin may collide with the caliper pin during braking, resulting in damage to the pin, which may lead to poor braking effect, or insufficient space for installing the pin during installation, which may cause damage to the pin. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a shock-absorbing floating caliper pin shaft, comprising a shaft body 1, a shaft sleeve 2 is fixedly connected to the outer surface of the shaft body 1, a shock-absorbing mechanism 3 is arranged on the outer surface of the shaft body 1, and a mounting mechanism 4 is arranged on the inner surface of the shaft sleeve 2;

The lower surface of the shaft body 1 is fixedly connected with the fixing ring 301, the lower surface of the fixing ring 301 is fixedly connected with the leather tube 302, the upper surface of the leather tube 302 is provided with an air inlet 303, the lower surface of the leather tube 302 is provided with an air outlet 304, the outer surface of the shaft body 1 is snap-connected with the connecting block 305, the lower surface of the connecting block 305 is provided with a first limiting hole 306, the inner surface of the first limiting hole 306 is snap-connected with the sleeve 307, the inner surface of the sleeve 307 is sleeved with the first spring 308, and the outer surface of the first spring 308 is fixedly connected with The limiting ring 309 is arranged through the fixing ring 301, the leather tube 302, the air inlet 303, the air outlet 304, the connecting block 305, the first limiting hole 306, the sleeve 307, the first spring 308 and the limiting ring 309. When braking, the caliper squeezes the limiting ring 309 to move the limiting ring 309 forward, squeezes the first spring 308, and retracts the first spring 308 into the first limiting hole 306 to reduce the squeezing force. Then the limiting ring 309 pushes the connecting block 305 forward to squeeze the leather tube 302, and the leather tube 302 enters a compressed state, so that the gas inside the leather tube 302 is discharged through the air outlet 304, and the squeezing force is consumed. Then when braking stops, the gas enters the leather tube 302 from the air inlet 303, and the leather tube 302 enters an extended state to push the parts back to their original positions.

[0020] Furthermore, the air inlet holes 303 are opened at equal intervals on the upper surface of the leather tube 302, and the air outlet holes 304 are opened at equal intervals on the upper surface of the leather tube 302. Through the setting of the leather tube 302, the squeezing force can be released by exhausting and the parts can be returned to their original positions by suction.

[0021] Furthermore, the first springs 308 are evenly spaced on the lower surface of the connecting block 305, and the sleeves 307 are evenly spaced on the lower surface of the connecting block 305. The setting of the sleeves 307 can protect the extension and retraction of the first springs 308 and prevent the position of the first springs 308 from being offset.

[0022] Furthermore, the mounting mechanism 4 includes a limit block 401, a second limit hole 402, a second spring 403, a sphere 404, a limit groove 405 and a slot 406. The outer surface of the shaft body 1 is fixedly connected to the limit block 401, the outer surface of the shaft body 1 is provided with a second limit hole 402, the inner surface of the second limit hole 402 is fixedly connected to the second spring 403, the upper surface of the second spring 403 is fixedly connected to the sphere 404, the inner surface of the sleeve 2 is provided with a limit groove 405, the inner surface of the sleeve 2 is provided with a slot 406, and the limit block 401, the second limit hole 402, the second limit hole 402, the inner surface of the second limit hole 402, ... The second limiting holes 402, the second spring 403, the ball 404, the limiting groove 405 and the clamping groove 406 are arranged. When the shaft body 1 needs to be installed, it is only necessary to align the limiting block 401 with the limiting groove 405 and push the shaft body 1 to the sleeve 2. The shaft body 1 will move along the limiting groove 405, and the inner wall of the sleeve 2 will squeeze the ball 404, and the ball 404 will squeeze the second spring 403, so that the second spring 403 will retract into the second limiting hole 402. When encountering the clamping groove 406, the second spring 403 will stretch to clamp the ball 404 in the clamping groove 406, and the installation of the shaft body 1 is completed.

[0023] Furthermore, the inner wall size of the limiting groove 405 matches the outer wall size of the limiting block 401, and the spheres 404 are evenly spaced on the inner surface of the shaft body 1. By setting the limiting groove 405, the installation position of the shaft body 1 can be guided to prevent the installation position from being offset.

[0024] Working principle: First, when the machine starts to run, when braking, the caliper squeezes the limit ring 309, so that the limit ring 309 moves forward, squeezes the first spring 308, and the first spring 308 retracts into the first limit hole 306, reducing the squeezing force. Then the limit ring 309 pushes the connecting block 305 forward, squeezing the rubber tube 302, and the rubber tube 302 enters a compressed state, so that the gas inside the rubber tube 302 is discharged through the air outlet 304, and the squeezing force is consumed. Then when the brake stops, the gas enters the rubber tube from the air inlet 303 302, the sleeve 302 enters the extended state, pushing the parts back to their original positions. When the shaft body 1 needs to be installed, it is only necessary to align the limit block 401 with the limit groove 405 and push the shaft body 1 to the sleeve 2. The shaft body 1 will move along the limit groove 405, and the inner wall of the sleeve 2 will squeeze the ball 404, and the ball 404 will squeeze the second spring 403, so that the second spring 403 will retract into the second limit hole 402. When encountering the slot 406, the second spring 403 will stretch to engage the ball 404 in the slot 406, and the installation of the shaft body 1 will be completed.
