Abstract

The invention discloses an automobile vacuum booster with the mechanical emergency braking auxiliary system function. A control valve assembly is installed inside a piston body hole, the hole is internally provided with a cylindrical boss with a center hole, the cylindrical boss is sleeved with a sliding valve, a control valve seat stretches into the center hole of the cylindrical boss, and a control valve spring front base abuts against the end face of a piston. A U-shaped sliding valve retaining sheet is clamped on the front shaft neck of the control valve seat. A U-shaped lock plate is clamped on the middle shaft neck of the control valve seat. The front end of the sliding valve is provided with four lugs, the outer side of the back end of the sliding valve is provided with a flange, the sliding valve is sleeved with an emitting spring abutting against the flange at the back end of the sliding valve, a sealing groove is formed in the flange of the sliding valve, an O-shaped sealing ring and the inner wall of a piston body are sealed in a matched mode, and a snap spring is connected with the sliding valve retaining sheet in a sleeved mode. The vacuum booster emergency braking function is achieved, assembling is very easy and convenient, the occupied space is very narrow and small, the connecting portion is reliable, the performance is reliable, and the defects that the electronic braking auxiliary function is high in cost and complex in structure are overcome.

Description

technical field [0001] The invention relates to an automobile vacuum booster, in particular to an automobile vacuum booster with the function of a mechanical emergency braking auxiliary system. Background technique [0002] The technology of the automobile industry is changing with each passing day, but its driving safety is an eternal topic. Since the birth of automobiles, the braking system has played a vital role in automobile safety. As a big automobile consumer country, on the one hand, the traffic is increasing day by day, on the other hand, the driving speed is constantly increasing, and many accidents are caused by drivers, such as forced lane changes, pedestrians suddenly crossing the road, improper speed control or insufficient distance between vehicles Many accidents caused by such reasons can be avoided by improving the braking process. [0003] Studies have shown that many drivers fail to apply adequate braking in emergency situations due to inexperience or phy...
