Description
technical field [0001] The invention relates to an automobile brake device, in particular to a brake booster device for an electric drive vehicle. Background technique [0002] In the traditional braking system, braking is achieved by the driver applying force on the brake pedal, which is amplified and transformed by the vacuum booster system into hydraulic pressure acting on the brake, thereby achieving braking. The vacuum booster system used in automobiles now consists of a vacuum booster with a brake master cylinder, a vacuum tank, a vacuum pump, and a vacuum tube. Among them, the vacuum booster with brake master cylinder uses the pressure difference between the vacuum and the atmosphere to amplify the braking force applied by the driver on the pedal, and transmits this force to the brake master cylinder to establish hydraulic pressure and realize pedal force direction. The change of hydraulic pressure, and then achieve braking. Among them, the vacuum tank is responsibl...
