Description

Technical Field

[0001] The utility model relates to a structural optimization of internal accessories of a brake caliper, in particular to an integrated brake block retaining spring with a return mechanism. Background Art

[0002] The braking force of disc brakes is mainly generated by the friction between the brake pads and the brake disc. After braking, the brake pads need to return to their original position in time and maintain a certain gap with the brake disc. At present, due to structural limitations, the brake pads of most disc brakes cannot return to their original position quickly after braking, and there is a lag phenomenon, which accelerates the wear of the brake pads and the brake disc, resulting in increased wear. The most effective solution at present is to add a return mechanism riveted on the brake pad to improve the brake pad return problem, but this mechanism takes up a large space, increases the number of parts and assembly processes. Utility Model Content

[0003] In order to solve the problems existing in the background technology, the utility model provides an integrated brake block retaining spring with a return mechanism. By adding a return mechanism to the retaining spring, the brake block can be returned after the vehicle braking is completed, which greatly reduces the dragging phenomenon.

[0004] The technical solution adopted by the utility model is:

[0005] The brake block retaining spring is in an inverted U shape as a whole. The two lower branches of the brake block retaining spring are two symmetrically distributed active return mechanisms for active return of the brake block. The two active return mechanisms are connected to the connecting reinforcement ribs arranged on the upper part of the brake block retaining spring through two symmetrically distributed protruding structures arranged in the middle part of the brake block retaining spring, forming an integrated structure.

[0006] The active return structure is mainly composed of an elastic part, an elastic part connecting part with a supporting function and a hook head for pulling the brake block, which are arranged and connected in sequence; the elastic part is an arc-shaped bending structure.

[0007] The connecting reinforcement rib has a stamping angle.

[0008] The brake block retaining spring comprises two symmetrically distributed retaining spring body connecting parts at the bottom, and the two active return mechanisms are respectively arranged at the two retaining spring body connecting parts.

[0009] The elastic part connecting portion is not arranged parallel to the surface of the clamping spring body connecting portion.

[0010] One end of the elastic part is connected to one side end of the connecting part of the clip body, and the other end of the elastic part is connected to the hook head via the connecting part of the elastic part.

[0011] The protruding structure and the clamp body connecting part located on the same side are connected through the brake block clamp spring sliding part. The clamp body connecting part and the brake block clamp spring sliding part are arranged non-parallel, so that an angle is formed between the clamp body connecting part and the brake block clamp spring sliding part.

[0012] A clamping foot is provided at the edge of the sliding part of the brake block clamping spring, and the clamping foot is arranged perpendicular to the sliding part of the brake block clamping spring and is used to fix the brake block clamping spring.

[0013] The top surface of the protruding structure is provided with a barb for fixing the brake block retaining spring and the brake block bracket.

[0014] The beneficial effects of the utility model are as follows: without adding other accessories, the braking force retaining spring is optimized so that it has a return function. When the car brakes, the brake block pulls the L-shaped hook to deform the elastic part, and after the braking, the spring force of the elastic part returns the brake block; the structure is simple, the installation and maintenance are convenient, and the number of parts and riveted assembly I-shaped parts are also reduced.

[0020] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the brake pad retaining spring is overall inverted U-shaped, and the two lower branches of the brake pad retaining spring are two symmetrically distributed active return mechanisms for the active return of the brake pad 7. The two active return mechanisms are connected to the connecting reinforcement rib 5 provided on the upper part of the brake pad retaining spring through two symmetrically distributed protruding structures 1 provided in the middle part of the brake pad retaining spring to form an integrated structure. The connecting reinforcement rib 5 has a stamping angle, and the protruding structure 1 is embedded in the convex strip of the brake pad bracket 6.

[0022] like Figure 2As shown, the active return structure is mainly composed of an elastic part 4, an elastic part connecting part with a supporting function and a hook head 3 for pulling the brake block 7, which are arranged and connected in sequence; the elastic part 4 is an arc-shaped bending structure; the elastic part 4 is provided with a concave punching hole to reduce the weight.

[0023] The brake block retaining spring comprises two symmetrically distributed retaining spring body connecting parts at the lower part, and two active return mechanisms are respectively arranged at the two retaining spring body connecting parts; the elastic part connecting part is arranged not parallel to the surface of the retaining spring body connecting part.

[0024] One end of the elastic part 4 is connected to one side end of the connecting part of the clip body, and the other end of the elastic part 4 is connected to the hook head 3 via the elastic part connecting part.

[0025] The protruding structure 1 and the connecting part of the retaining spring body located on the same side are connected through the brake block retaining spring sliding part. The retaining spring body connecting part and the brake block retaining spring sliding part are arranged non-parallel, so that there is an angle between the retaining spring body connecting part and the brake block retaining spring sliding part; the retaining spring body connecting part and the brake block retaining spring sliding part are embedded in the groove of the brake block bracket 6.

[0026] A clamping foot 2 is provided at the edge of the sliding part of the brake block clamping spring. The clamping foot 2 is arranged perpendicular to the sliding part of the brake block clamping spring. The clamping foot 2 clamps the bracket to fix the brake block clamping spring.

[0027] like Figure 3 As shown, the top surface of the protruding structure 1 is provided with a barb for fixing the brake pad retaining spring and the brake pad bracket 6 , and the barb is clamped in the boss groove of the brake pad bracket 7 .

[0028] like Figure 4 As shown, during operation, the brake block 7 slides on the elastic part connecting portion of the brake block retaining spring, and the elastic part connecting portion plays the role of supporting the brake block 7. When the car brakes, the brake block 7 pulls the active return mechanism to deform. When pressurized, the brake block 7 pulls the hook head 3 to deform the elastic part 4. After the braking is completed, the elastic part 4 recovers and pulls the brake block 7 back to its original position, thereby reducing the caliper drag phenomenon.

[0029] The above examples are further explanations of the present invention, not specific limitations of the present invention. Any structure that is simply modified from the present invention falls within the protection scope of the present invention.
