Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a brake hub with an anti-impurity blocking effect. Background Art

[0002] The brake drum is a part of the drum brake system. When braking, the piston applies pressure to two pairs of semi-circular brake shoe pads, making them tightly adhere to the inner wall of the drum chamber, thereby generating friction to stop the rotation of the wheel. The material of the brake drum is generally HT200-300 (i.e., gray cast iron), the matrix structure is mainly pearlite, as well as a small amount of ferrite and cementite, the main graphite is grade A, the morphology is long flake, and the length grade is 4-6, which plays the role of heat dissipation, increasing friction performance, and reducing braking noise.

[0003] Each brake hub corresponds to a brake pad, which is a standard configuration of the automobile braking system. Frequent start-stop, traffic lights, traffic jams and other urban driving conditions will accelerate the wear of the brake pads. Therefore, it is necessary to regularly check the wear status of the brake pads and replace them when necessary to ensure driving safety.

A first brake pad 3 is arranged on the outer side of the mounting rod 2. Connecting holes 13 are arranged at equal intervals inside the first brake pad 3. The outer side of the mounting rod 2 is slidably connected with the inside of the connecting hole 13. A first nut 4 is threadedly connected to the outer side of the mounting rod 2. A second brake pad 6 is arranged on one side of the first brake pad 3. A placement groove 7 is formed on one side of the second brake pad 6. The inside of the placement groove 7 is slidably connected with the outer side of the first brake pad 3. An installation component is arranged between the brake hub body 1 and the second brake pad 6;

[0026] The installation component includes installation blocks 8 which are fixedly connected to the outer side of the brake hub body 1 at equal intervals. Installation holes 9 are arranged at equal intervals on one side of the second brake pad 6. Bolts 10 are arranged between the installation blocks 8 and the installation holes 9. A second nut 11 is arranged on the outer side of the bolt 10.

[0027] In the above technical solution, considering that each brake hub corresponds to a brake pad, which is a standard configuration of an automotive braking system, frequent start-stop, traffic lights, traffic jams and other urban driving conditions will accelerate the wear of the brake pads. To solve such problems, the specific operation is as follows: A second brake pad 6 is sleeved on the outer side of the first brake pad 3, and then the second brake pad 6 and the first brake pad 3 are successively installed on the brake hub body 1 by using the mounting rod 2, the first nut 4 and the installation component. When the first brake pad 3 is worn flat, the second brake pad 6 can be continued to be used, realizing a double brake pad structure, extending the service life of the overall braking system, reducing the need for frequent replacement of brake pads, and thus saving maintenance costs.

[0028] Refer to Figures 1 to 4 , In a preferred embodiment, a rubber ring is arranged on the inner wall of the placement groove 7. Axial holes 14 are formed in both the brake hub body 1 and the inside of the first brake pad 3. First heat dissipation holes 5 are arranged at equal intervals on the outer side of the first brake pad 3. Second heat dissipation holes 12 are arranged at equal intervals on the outer side of the second brake pad 6. The first brake pad 3 and the second brake pad 6 are made of semi-metallic material; arranging the rubber ring can effectively improve the sealing performance between the first brake pad 3 and the second brake pad 6, preventing external substances such as dust and moisture from entering the second brake pad 6. The first brake pad 3 and the second brake pad 6 are provided with heat dissipation holes at equal intervals, so that the heat generated during the braking process can be dissipated faster, preventing brake fade caused by too high temperature.

[0029] Working principle: When in use, first align the through hole of the mounting block 8 with the mounting hole 9, pass the bolt 10 through from one side of the brake hub body 1, and then screw on the second nut 11 to make the second brake pad 6 fit against the brake hub body 1. Then pass the mounting rod 2 through the connection hole 13, place one-third of the first brake pad 3 into the placement groove 7, so that one side of the first brake pad 3 fits against the inner wall of the placement groove 7, and tighten the first nut 4, then the brake hub body 1, the first brake pad 3 and the second brake pad 6 can be installed together. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
