Description

Technical field

[0001] The present invention relates to the field of braking of a motor vehicle, and more particularly to a hydraulic power brake pressure regulating system for a motor vehicle.Background technique

[0002] At present, the braking system of motor vehicles is mainly a vacuum boost system. When the brake pedal is stepped on, the control force of the pedal mechanism pushes the control valve of the vacuum booster to enable air into the vacuum servo chamber. As the air is inserted, the pressure difference occurs in both sides of the vacuum servo ventricular diaphragm, and this thrust is directly active to generate pressure in the brake master cylinder, so that the pressure of the brake master is output. multiply. If the vacuum booster failure or vacuum line does not have a vacuum, the pedal mechanism directly pushes the control valve, the vacuum servo air chamber and the brake master cylinder push rod, and can generate a brake force. At this time, the force on the active brake ...
