Description

Technical Field

[0001] The utility model belongs to the technical field of braking and relates to a brake caliper, in particular to a brake caliper which is easy to maintain. Background Art

[0002] The brake disc of a car also rotates during the driving process, so the brake is needed to slow down, stop or keep the moving parts stopped. In cars and other vehicle devices, the brake mechanism generally adopts a disc brake mechanism, and its main structure is as follows: the brake disc is fixed on the wheel shaft, and a hydraulic clamping device is provided at the edge of the brake disc. When braking, only the friction plate in the clamping device needs to hold the brake disc tightly through the hydraulic system, and the brake disc will quickly slow down under the action of friction.

[0003] In reality, after long-term use, the grease in the brake guide pins in the brake caliper will disappear, causing rust on the guide pins and causing problems with the car's brake disc. When you need to maintain the guide pins or replace the brake pads, you need to twist the bolts to loosen them, making it inconvenient to maintain the brake disc. Summary of the invention

DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, the brake caliper which is easy to repair comprises a caliper body 1, a brake pad 2 and a bracket 3. The caliper body 1 is composed of a caliper body 4 and a piston assembly 5. Guide pins 6 are arranged at both the front and rear ends of the bracket 3. A mounting hole 7 for mounting the guide pin 6 is provided on the bracket 3. The guide pin 6 is composed of a floating latch 8 and a fixed latch 9. A mounting hole 10 for mounting the fixed latch 9 is provided in the floating latch 8. A clamping device 11 is provided on the fixed latch 9. A partition 12 is arranged inside the fixed latch 9. The clamping device 11 is composed of a clamping mechanism 13, a transmission plate 14 and a clamping protrusion 15. The clamping mechanism 13 is composed of a pressing block 16 and a return spring 17.

[0015] To further elaborate, the clamping device 11 is symmetrically arranged with the partition 12 as the center, the clamping protrusion 15, the pressing block 16 and the transmission plate 14 are integrally arranged, and a movable space 18 for the transmission plate to move is opened inside the fixed pin 9.

[0016] To be more specific, a limit block 19 and a limit block 20 are respectively provided on both sides of the pressing block 16 and on both sides of the snap-fitting protrusion 15, and a limit space 1 21 and a limit space 22 are respectively provided in the fixed pin 9 and on both sides of the pressing block 16 and on both sides of the snap-fitting protrusion 15.

[0017] When installing and fixing, you can first press the pressing block 16 to make the pressing block enter the inside of the fixed pin 9. When the pressing block moves inside, the transmission plate 14 drives the engaging protrusion 15 to move inside the fixed pin 9. Then put the fixed pin 9 into the second installation hole 10 until the fixed pin abuts against the positioning portion 23. Then release the pressing block, and the reset spring 17 resets the pressing block and drives the engaging protrusion 15 to reset and engage with the engaging groove 24, thereby realizing the rapid installation of the bracket 3 and the clamp body 1.

[0018] In further detail, a positioning portion 23 for positioning the fixed plug 9 is provided in the second installation hole 10 , and a snap-in groove 24 cooperating with the snap-in protrusion 15 is provided in the floating plug 8 and relative to the second installation hole 10 .
