Description

technical field

[0001] The invention relates to the field of automobile manufacturing, in particular to a brake booster system for vehicles. Background technique

[0002] In the vehicle, the brake booster system is used to make up for the insufficient pressure of the driver when the brake pedal is stepped on to strengthen the braking effect of the braking system. At present, the brake boosters used in the field of automobile manufacturing include hydraulic servo brake boosters and vacuum brake boosters. Among them, the hydraulic servo brake booster uses a high-pressure hydraulic source or a high-pressure oil source as a boost source, and by changing the brake master cylinder, designing a special hydraulic pipeline, and controlling the boost pressure, brake boost is achieved. The vacuum brake booster uses the pressure difference between the vacuum degree generated by the engine throat or specially equipped vacuum equipment and the atmospheric pressure on the two ends of the ...
