The correct working principle of the brake pump is as follows:
Brake pump is an indispensable chassis brake part of the brake system, its main role is to push the brake pad, brake pad friction brake drum. Slow down and bring to a standstill. After the brake is pressed, the master pump generates thrust to press the hydraulic oil to the sub-pump, and the piston inside the sub-pump starts to move under the liquid pressure to push the brake pad.
The hydraulic brake is composed of the brake master pump and the brake oil storage tank. They're connected to the brake pedal at one end and the brake tubing at the other. Brake oil is stored in the brake pump, and there is an oil outlet and an oil inlet.
1. When the driver steps on the brake pedal, the piston of the master pump moves forward to close the bypass hole. Then, the oil pressure is built up in front of the piston. Then the oil pressure is transferred to the brake pump through the pipeline;
2. When the brake pedal is released, the piston of the master pump is set back under the action of the oil pressure and the return spring. After the pressure of the braking system drops, the excess oil returns to the oil can;
3, two-foot braking, the oil pot from the compensation hole into the front of the piston, so that the oil in front of the piston increases, and then in the braking, braking force increases.
