Automobile is when running at high speed, incident for burst, break down or the unexpected variation of road conditions as certain parts on the automobile, chaufeur will cause traffic accident as can not in time touching on the brake, existing vacuum booster does not in case of emergency have to realize brake, the function of slowing down automatically, in case of emergency easily causes traffic accident.
The utility model content:
Can not in case of emergency realize the deficiency of braking, slowing down automatically in order to overcome existing vacuum booster, the utility model provides a kind of charged magnet valve vacuum booster, this charged magnet valve vacuum booster is existing technical the improvement, can in case of emergency accept electric signal and realize brake automatically, slow down and not controlled by driver's operation, thus the generation that avoids traffic accident.
The technical solution of the utility model is: this charged magnet valve vacuum booster comprises forward and backward housing and diaphragm, the chamber that diaphragm surrounds forward and backward housing is separated into ante-chamber and back cavity, ante-chamber and back cavity are communicated with engine air inlet tube and plasmas channel respectively, be connected with push rod on the diaphragm, push rod cup is installed on the push rod, chamber passage before and after push rod cup is provided with, chamber, front and back passage are opened by appliance controling element control and are closed, and plasmas channel is opened by the back cavity solenoid control and be closed.
The ante-chamber electromagnetic valve is installed on the described front case, and chamber, front and back passage links to each other with the ante-chamber electromagnetic valve by placing the vacuum hose in the ante-chamber.
Be equipped with on the described push rod with the cooresponding chamber of push rod cup in electromagnet, before and after on the chamber passage with the chamber in the corresponding position of electromagnet be fixed with sealing member, be provided with spring between electromagnet and the push rod cup in the chamber, electromagnet links to each other with the attaching plug that is arranged on preceding cavity outer wall by lead in the chamber.
The utlity model has following beneficial effect: owing to take such scheme, in case of emergency, send electric signal from trend appliance controling element and back cavity electromagnetic valve, make the appliance controling element action with chamber, front and back passage closure, plasmas channel is opened in the action of back cavity electromagnetic valve, back cavity communicates with the external world, the launched machine of ante-chamber this moment is evacuated, and back cavity enters air, makes diaphragm drive push rod cavity direction motion forward, push rod promotes master brake cylinder first piston group, thereby makes master brake cylinder produce braking.This device can be realized automatically braking, slow down and not controlled by driver's operation, thus the generation that avoids traffic accident.The utility model is reasonable in design, can keep former installing space constant after the installation, thereby can not change other interface size.
