1. Introduction
Brake master cylinder, also known as “master cylinder”, “master cylinder”, with the main part of the vehicle brake system, also depending on the vehicle divided air brake master cylinder brake master cylinder and oil are two, the majority of passenger cars in general (such as cars, minivan, etc.) of the brake master cylinder brake master cylinder oil is used, while commercial vehicles (such as trucks, tractors etc.) of the brake master cylinder is normally used air brake master cylinder.
2, the working principle
brake oil
using an oil brake has a brake master cylinder above savings brake fluid reservoir tank, and the bottom is equipped with oil out of the piston within the cylinder mouth.
Brake master cylinder When the brakes the brake pedal force by the piston in the cylinder, and then by acting ram, the cylinder of the brake oil pressure is transmitted to each wheel brake points pump, a braking function. When the brake pedal is released, in the brake master cylinder oil outlet is closed, the oil inlet is opened, so that brake oil flowing from a brake master cylinder into the brake cylinder, back to the original state. Air brake
works using an air master cylinder brake master cylinder and the brake oil is used as the basic brake, which acts both as a valve, except that the oil brake master cylinder after the braking action controls brake fluid returned to the storage tanks, the use of air brakes in vehicles usually
brake master cylinder typically suspended several large air reservoir on the frame, the gas after the braking action will be discharged directly, therefore we often hear the loud exhaust sound when a large truck brakes.
