Description

Technical Field

[0001] The utility model relates to the field of electronic brake sealing accessories for new energy vehicles, in particular to a bleed valve protection cap for electronic brakes. Background Art

[0002] The braking system is an important guarantee for the safe driving of automobiles. Compared with the traditional hydraulic braking system, the electronic control braking system has many advantages such as simple structure, fast braking response, high control accuracy, flexible layout, and consistent pedal characteristics. It is easy to integrate with the vehicle dynamic control system, which can meet the regenerative braking system requirements of electric vehicles and hybrid vehicles, and has good development prospects. With the development of the disc brake system, the drum brake system has been gradually replaced and optimized. As a key component of the disc brake system, the caliper directly determines the quality of the braking performance. The current domestic situation is affected by the lack of independent intellectual property rights in my country's automobile industry. There is still a certain gap between my country's disc brake system and the world's first-class level in terms of production technology, product performance, quality and market share. The protection and sealing effect of the bleed valve is not good, and it is not easy to disassemble. Utility Model Content
