Description

Technical Field

[0002] With the rapid development of modern industrial technology, electric motors and their supporting equipment are increasingly used in fields such as industrial automation, rail transportation, and power transmission. As a crucial component of the motor system, the performance of the electromagnetic brake directly impacts the safety, stability, and reliability of the entire system. The armature, a key component of the electromagnetic brake, has a significant impact on its overall performance, including its design, material, and performance.

[0003] Open brakes are commonly used in vehicle braking systems. These brakes transmit braking force through exposed friction pads and brake discs. However, this design is susceptible to environmental influences such as dust and moisture, leading to reduced braking performance and a shortened service life. Furthermore, open brakes have poor heat dissipation, and prolonged high-load operation can cause elevated temperatures, further exacerbating wear. Furthermore, the friction pads and brake discs are exposed to the external environment for a long time, making them susceptible to contamination and poorly resistant to dust and water, resulting in unstable braking performance and a shortened service life. Therefore, a closed brake has been proposed to address these issues. Utility Model Content

Dust and other impurities are prevented from entering the brake interior, ensuring the normal operation of the brake. Furthermore, the overall structure is compact and easy to install, making it suitable for various vehicle models and industrial equipment, achieving the advantages of strong practicality and good protective effect.

By providing the abutment rod 11 and the anti-slip rubber gasket 12, the braking effect of the brake pad 2 is further improved. By providing the end cover body 1 and the sealing gasket 4, the sealing performance of the brake is improved, and problems such as oil leakage, dust and moisture intrusion are avoided, thereby extending the service life of the brake, effectively enhancing the protective effect of the brake, and preventing dust and other impurities from entering the interior of the brake, ensuring the normal operation of the brake, and the overall structure is compact and easy to install, suitable for various vehicle models and industrial equipment.
