Car braking malleation booster

The utility model relates to an automotive brake device specifically is a car braking malleation booster, and solve the negative pressure that produces when current vacuum booster relies on the engineto admit air and have as the power supply that vacuum power is not enough, brake force is not enough, brake hysteresis scheduling problem, including procapsid and back casing, the internal control valve assembly that is equipped with of backshell, control valve assembly's center is equipped with the push rod, and the push rod front end even has the control valve piston, and it has the brake master cylinder push rod to run through in the procapsid, and the malleation helping hand air pump by motor drive is set up to procapsid one side below, and malleation helping hand gas pump suction port passes through intake pipe and back casing intercommunication, be equipped with pressure switch on the malleation helping hand air pump, pressure switch establishes ties in motor control circuit.
