The brake pump is to drive the gas generated by the gas pound through the engine operation and then reach the air packet through the check valve. Then to the main pump, the driver steps on the main pump, the piston of the main pump moves down, leading to the gas to the brake pipe, and then the brake pump drives the rotating shaft, so that the outer diameter of the brake shoe is enlarged and the brake drum is combined, which leads to the safety of the vehicle in driving.
The working principle of automobile brake sub-pump is:
1, the key working principle of the brake is from friction, with the help of the brake pad and brake disc (drum) and tire and ground friction, the kinetic energy of the vehicle will be converted into the heat energy after friction, the car will stop;
2, a good brake system with a good effect rate must be able to supply stable, sufficient, adjustable braking force, and has good hydraulic transmission and heat dissipation capacity, to ensure that the force applied by the driver from the brake pedal can be fully effective to the main pump and each pump, and prevent the hydraulic failure and brake decline affected by high heat;
3, Automobile brake system includes disc brake and drum brake, but in addition to the cost advantage, the efficiency of drum brake is far less than that of disc brake, so the brake system discussed in this paper will only be based on disc brake. There is a great deal to be said for the quality of your new car's maintenance
