Decoupling type electro-hydraulic brake with hydraulic braking force feedback

The invention discloses a decoupling type electro-hydraulic brake with hydraulic braking force feedback. The decoupling type electro-hydraulic brake comprises a brake master cylinder, a liquid storage tank, a motor, a gear, a rack, a pedal travel sensor, a controller, a manual cylinder piston, a manual cylinder, a braking force feedback cylinder, a simulation piston, a simulation spring, a feedback piston, a proportional pressure valve and a return spring. Compared with a vacuum booster brake and an air pressure brake, when a driver does not step on the brake, the brake can be braked according to an instruction of a vehicle control unit, and automatic driving is facilitated. Due to the fact that the decoupling type brake, the brake pedal and the brake master cylinder are not directly and mechanically connected, coordinated type energy recovery braking can be conveniently carried out. Compared with a common decoupling brake, the braking force can be directly fed back to the brake pedal during braking, and the
