The electromagnetically controlled secondarily supercharging automobile braking general pump with two parallel cavities includes one upper pump body and one lower pump body. The upper pump body has one upper piston assembly and one balance lever; and the lower pump body includes two basically identical parts below the upper pump body and with brake valve assembly brake air inlet and outlet holes each. The upper piston assembly contains upper piston and sealing structure, and one supercharging air chamber is formed between the upper piston and the upper pump body and communicated via one solenoid valve to the brake air outlet hole, with the solenoid valve being connected to the control circuit. The present invention has both forced braking and flexible braking functions for fitting different road condition and vehicle condition and simultaneous front and rear wheel braking with raised safety. |
