Description

Technical Field

[0001] This utility model relates to the field of brake shoe technology, specifically a highly stable brake shoe. Background Technology

[0002] Brake shoes are an important component of drum brakes, providing high braking force: the large contact area between the brake shoes and the brake drum generates significant braking force, meeting the braking needs of vehicles under various driving conditions. In particular, they can quickly bring the vehicle to a stop during emergency braking. They also offer good stability: during braking, the brake shoes experience relatively even force distribution, and their simple structure makes them less prone to failure, ensuring the stable operation of the braking system and providing reliable safety for vehicle operation.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221347684U) discloses a brake shoe with easily replaceable friction pads. The invention includes a brake shoe body with a mounting groove on its surface. A mounting block is slidably connected to the inner side of the mounting groove. A friction pad is fixedly mounted on one end of the mounting block. A threaded groove A is formed on one side of the mounting block, and a threaded hole A is formed on the surface of the brake shoe body. This invention utilizes a structure including a mounting groove, mounting block, friction pad, threaded groove A, threaded hole A, bolt A, slot, long rod, locking block, round block, tension spring, and pull rod. This allows workers to quickly replace the friction pads on the brake shoe body using bolt A, reducing replacement costs. Furthermore, the locking block secures the tightened bolt A, preventing loosening and improving the stability of the friction pad installation.

[0004] Although the aforementioned patent enables operators to quickly replace the friction pads on the brake shoes through the arrangement of components such as friction pads, mounting grooves, and mounting blocks, thereby increasing the replacement speed, the brake shoes generate significant friction during braking. This friction causes the brake shoes to heat up rapidly, and during the recovery process, the heat is impacted into the brake disc by the impact force of the recovery. Over time, this is very detrimental to improving the service life of the brake disc.

[0005] Therefore, this invention provides a highly stable brake shoe to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a highly stable brake shoe, which aims to solve the problems mentioned in the background art.

[0011] The buffer assembly includes a slot formed on the outer wall of the brake shoe body, a retaining sleeve fixedly connected to the inner wall of the slot, a sliding rod fixedly sleeved on the inner wall of the retaining sleeve, a hollow rod slidably sleeved on the outer wall of the sliding rod, an air-dissipating groove formed on the outer wall of the hollow rod, and several air-dissipating grooves formed on the outer wall of the hollow rod, a mounting plate fixedly connected to the end of the hollow rod, and a support assembly provided on the inner wall of the brake shoe body.

[0016] As a preferred technical solution of this application, a rubber gasket is fixedly connected to the inner wall of the mounting plate, and the inner wall of the rubber gasket is provided with an extrusion groove.

[0017] (III) Beneficial Effects

[0018] By setting up a buffer component, the impact force during brake shoe retraction can be reduced, mitigating the impact effect of the impact force on the brake disc caused by heat. Utilizing the sleeve, slide bar, hollow bar, and heat dissipation groove, the slide bar slides within the hollow bar during brake shoe retraction, generating a damping effect to alleviate some of the impact force. Furthermore, the heat dissipation groove instantly dissipates the retracted air, generating airflow to cool the interior of the brake disc and improving the heat dissipation effect of the brake shoes.

A sliding rod 6 is fixedly sleeved on the inner wall of the retaining sleeve 5. A hollow rod 7 is slidably sleeved on the outer wall of the sliding rod 6. An air-dissipating groove 8 is formed on the outer wall of the hollow rod 7. There are several air-dissipating grooves 8. A mounting plate 9 is fixedly connected to the end of the hollow rod 7. A support assembly is provided on the inner wall of the brake shoe body 1.

[0028] The support assembly includes a reinforcing rib 10 fixedly connected to the inner wall of the brake shoe body 1. The upper top of the reinforcing rib 10 is fixedly connected to a diagonal brace 11, and the diagonal brace 11 is fixedly connected to the inner wall of the brake shoe body 1. A connecting assembly is provided on the outer wall of the mounting plate 9.

[0029] Specifically, the installation of the sleeve 2 and the roller 3 facilitates the installation of the brake shoe body 1 and the brake disc, improving the installation efficiency of the operator. The buffer component reduces the impact force of the brake shoe body 1 during retraction through the cooperation of various components. At the same time, the airflow impact during retraction dissipates heat inside the brake shoe body 1, improving the service life of the brake shoe. The slot 4 securely connects the sleeve 5, ensuring the stability of the internal slide rod 6 during operation. The retracted hollow rod 7 slides on the outer wall of the slide rod 6, causing airflow to move. This airflow then moves through the air dissipation groove 8 on the outer wall of the hollow rod 7, reducing the impact force of the brake shoe body 1 during retraction and dissipating heat through the airflow, preventing excessive temperature from affecting the braking effect. The installation plate 9 further securely connects to the brake disc. Together with the reinforcing rib 10 and the diagonal brace 11, the stability of the brake shoe is improved, preventing brittle fracture. This component has a simple structure, strong practicality, and improves the stability and usability of the brake shoe through the cooperation of various components.

[0032] The outer wall of the brake shoe body 1 is fitted with friction strips 15 to improve braking ability, and there are several friction strips 15.

[0033] A rubber washer 16 is fixedly connected to the inner wall of the mounting plate 9, and the inner wall of the rubber washer 16 has an extrusion groove.

[0034] Specifically, the installation effect can be improved by setting up the connecting components. By utilizing the cooperation of spring 14, bolt and mounting ring 13, after the bolt is installed, the setting of spring 14 can play a prestressing effect on the bolt after compression, thereby improving its buffering capacity. The friction strip 15 on the outer wall of the brake shoe body 1 can improve the friction of the brake shoe and improve the braking effect.
