Description

A type of automotive brake pump housing Technical Field

[0001] This utility model relates to the field of brake pump housing technology, specifically to an automotive brake pump housing. Background Technology

[0002] The brake pump housing is a core component of the braking system. It is a robust metal or composite material housing that houses key parts such as pistons, springs, and seals, forming a sealed hydraulic chamber. When the driver presses the brake pedal, the pressure from the master cylinder is transmitted through the lines to the pump housing, pushing the internal piston to move and converting the brake fluid pressure into braking force that clamps the brake disc or drum. Therefore, the pump housing not only secures and protects the internal components but is also a crucial safety feature, bearing high pressure and ensuring a leak-proof brake fluid seal.

[0003] However, existing brake pump housings are cumbersome to install and disassemble during use, and internal maintenance is difficult. Therefore, those skilled in the art have provided an automotive brake pump housing to solve the problems mentioned in the background section. Summary of the Invention
