Description

Technical Field

[0001] The utility model relates to a brake pad with a countersunk hole structure, belonging to the field of brake pad processing. Background Art

[0002] Brake pads are mainly used for braking during vehicle driving. Brake pads are composed of a steel backing and a friction pad. Currently, two blind holes are punched directly on the steel backing during the processing of brake pads for installing push rods. The difficulty in punching blind holes will lead to inconsistent depths of the two blind holes, resulting in uneven force when the two push rods push the brake pads, affecting braking performance. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a brake pad with a countersunk structure and a reasonable structural design.

[0004] The technical solution adopted by the present invention to solve the above problems is: the brake pad with a countersunk hole structure includes a steel back and a friction plate, the friction plate is arranged on the back of the steel back, and the steel back is provided with a pressure plate block and an alarm card slot. Its structural characteristics are: a countersunk hole is provided on the steel back, a gasket is provided in the countersunk hole, and a welding mesh is welded on the back of the steel back, which can fix the gasket in the countersunk hole.

[0005] Furthermore, a casting groove is provided on the back side of the steel back, and the casting groove is connected to the countersunk hole.

[0006] Furthermore, the friction plate is formed by casting the friction material on the welding mesh and then cooling it.

[0007] Furthermore, the upper portion of the countersunk hole is used for installing a gasket, and the lower portion of the countersunk hole is used for installing a push rod.

[0008] Furthermore, the push rod is in contact with the gasket.

[0009] Compared with the existing technology, the utility model has the following advantages: the brake pad has two countersunk holes punched on the steel back and gaskets installed in the countersunk holes. Since the thickness of the two gaskets is consistent, it can ensure that the brake pad is evenly stressed when the push rod pushes the brake pad to brake, thereby improving its braking performance.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0016] Example

[0017] See also Figures 1 to 4 As shown, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, if there are references to terms such as "upper", "lower", "left", "right", "middle" and "one" in this specification, they are only for the convenience of description and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be considered as the scope of the implementation of the present invention without substantially changing the technical content.

[0018] The brake pad with a countersunk structure in this embodiment includes a steel back 1 and a friction plate. The friction plate is arranged on the back of the steel back 1. The steel back 1 is provided with a pressure plate block 2 and an alarm card slot 3. The friction plate is formed by casting friction material on a welded mesh 5 and then cooling it.

[0019] In this embodiment, a countersunk hole 6 is provided on the steel back 1 , and a gasket 7 is provided in the countersunk hole 6 . A welding mesh 5 is welded to the back of the steel back 1 , and the welding mesh 5 can fix the gasket 7 in the countersunk hole 6 .

[0020] A casting trough 4 may also be provided on the back of the steel back 1 , the casting trough 4 being connected to the countersunk hole 6 , the upper portion of the countersunk hole 6 being used to mount a gasket 7 , the lower portion of the countersunk hole 6 being used to mount a push rod, and the push rod being in contact with the gasket 7 .

[0021] Specifically, the brake pad with a countersunk hole structure is provided with a countersunk hole 6 on the steel back 1, and a gasket 7 is installed in the upper part of the countersunk hole 6, so that when the friction material is cast, the friction material is prevented from flowing into the lower part of the countersunk hole, thereby playing a sealing role; when in use, the brake pad can be pushed out by the push rod, and since the cross-section of the gasket 7 is larger than the cross-section of the push rod, the entire brake pad can be evenly stressed, and the large force-bearing area increases the friction between the brake pad and the brake disc; the gasket 7 can avoid direct contact between the friction material and the push rod, thereby playing a heat insulating role; by casting the friction material onto the welded mesh 5, the friction pad is formed after the friction material cools down, thereby improving the strength of the friction pad.

[0022] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is merely an example of the structure of the utility model. Any equivalent changes or simple changes made based on the structure, features and principles described in the concept of the utility model patent are included in the scope of protection of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should fall within the scope of protection of the utility model.
