Description

Technical Field

[0001] The utility model belongs to the field of brake calipers, and relates to a brake caliper, in particular to a novel brake caliper. Background Art

[0002] A brake caliper refers to a disc brake caliper, which is a type of disc brake. Its rotating element is a metal disc that works with its end face, called a brake disc. The fixed element is a brake block composed of a friction block with a small working area and its metal back plate. There are 2 - 4 of these brake blocks in each brake, and these brake blocks and their actuating devices are all installed in a caliper-shaped bracket that straddles both sides of the brake disc, collectively referred to as a brake caliper.

[0003] In the existing brake caliper, the brake pads will wear after long-term use, and there will be a certain deviation in the wear degree of the surface of each position of the brake pads. As a result, when relying solely on the piston to push and squeeze during later use, local deviation will occur, and a part of the brake pads will not fit the brake disc, leading to a decrease in braking ability. Summary of the Invention

[0004] The purpose of the utility model is to provide a novel brake caliper with relaxation for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A novel brake caliper includes a caliper body, a first piston, brake pads, and a bracket. A piston cylinder for installing the piston is provided on the caliper body. It is characterized in that a gap adjustment component one is arranged in the piston cylinder relative to the piston. The gap adjustment component consists of a housing, a second piston, and a cylinder. An oil inlet is provided on the housing. An oil inlet groove is opened at the upper end of the inner wall of the housing where it contacts the second piston. A partition layer is provided on the second piston, and an oil inlet hole is opened on the partition layer. A one-way valve is arranged in the cylinder relative to the oil inlet hole. Gap adjustment component two is arranged on both sides of the caliper body relative to the piston cylinder.

[0006] In the above novel brake caliper, installation grooves for installing gap adjustment component two are opened on both sides of the caliper body relative to the piston cylinder. The gap adjustment component two consists of an adjustment spring and an adjustment convex block.

[0007] In the above novel brake caliper, a limit retaining ring is provided on the cylinder.

[0008] In the above novel brake caliper, a positioning installation part is provided at the lower end of the cylinder, and a positioning groove matching the positioning installation part is opened on the brake pad.

[0009] Compared with the prior art, the utility model can adjust the distance between the brake pad and the brake disc through the first gap adjustment component when the thickness of the brake pad decreases after long-term wear, so as to make the braking effect better. The second gap adjustment component arranged on both sides of the piston cylinder can, when the brake pad is worn and the surface of the brake pad is uneven, drive the adjustment convex block to squeeze one end of the brake pad through the adjustment spring, so that the brake pad fits more tightly and the braking effect is improved.

Detailed Description of the Preferred Embodiments

[0013] The following are specific embodiments of the utility model in combination with the drawings, and the technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.

[0014] As Figure 1 , Figure 2 shown, the novel brake caliper includes a caliper body 1, a first piston 2, a brake pad 3 and a bracket 4. A piston cylinder 5 for installing a piston is opened on the caliper body 1. A first gap adjustment component 6 is arranged in the piston cylinder 5 and relative to the piston. The gap adjustment component is composed of a housing 7, a second piston 8 and a cylinder 9. An oil inlet 10 is arranged on the housing 7. An oil inlet groove 11 is opened at the upper end of the inner wall of the housing 7 and in contact with the second piston 8. A partition layer 12 is arranged on the second piston 8. An oil inlet hole 13 is opened on the partition layer 12. A check valve 14 is arranged in the cylinder 9 and relative to the oil inlet hole 13. A second gap adjustment component 15 is arranged on both sides of the caliper body 1 relative to the piston cylinder 5. After the brake pad 3 is worn for a long time, the thickness of the brake pad 3 will decrease, resulting in a reduction in the contact area between the brake pad 3 and the brake disc, and the braking effect becomes poor. The first gap adjustment component 6 can make the oil enter the interior of the cylinder 9 to push the brake pad 3 forward, automatically adjusting the gap to make the braking effect better.

[0015] Specifically, mounting grooves 20 for mounting the second clearance adjustment assembly 15 are formed on both sides of the caliper body 1 relative to the piston cylinder 5. The second clearance adjustment assembly 15 is composed of an adjustment spring 17 and an adjustment protrusion 18. The second clearance adjustment assemblies 15 provided on both sides of the piston cylinder 5 can drive the adjustment protrusion 18 to squeeze one end of the brake pad 3 through the adjustment spring 17 when the brake pad 3 wears and the surface of the brake pad 3 is uneven, so that the brake pad 3 fits more tightly, improving the braking effect.

[0016] Specifically, a limit retaining ring 19 is provided on the air cylinder 9.

[0017] Specifically, a positioning and mounting portion 21 is provided at the lower end of the air cylinder 9, and a positioning groove 16 matching the positioning and mounting portion 21 is formed on the brake pad 3.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains may make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0019] Although terms such as caliper body 1, first piston 2, brake pad 3, bracket 4, piston cylinder 5, first clearance adjustment assembly 6, housing 7, second piston 8, air cylinder 9, oil inlet 10, oil inlet groove 11, partition layer 12, oil inlet hole 13, one-way valve 14, second clearance adjustment assembly 15, positioning groove 16, adjustment spring 17, adjustment protrusion 18, limit retaining ring 19, mounting groove 20, positioning and mounting portion 21 are used more frequently in this article, the possibility of using other terms is not excluded. These terms are only used to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
