Introduction Of EV Brake Booster Pump 1

Pulished on Mar. 19, 2019

As an EV Brake Assist System Factory, NEV will introduce the structure of the Brake Booster Vacuum Pump.

The Brake Booster Vacuum Pump is a large diameter vacuum chamber. The inside has a diaphragm (or piston) with a push rod in the middle. The cavity is divided into two parts, one part is connected to the atmosphere, and the other part is passed. The pipe is connected to the engine intake pipe. It uses the principle of taking in air when the engine is working, causing one side of the vacuum of the booster pump, and the pressure difference relative to the normal air pressure on the other side, and using this pressure difference to strengthen the brake thrust. If there is even a small pressure difference on both sides of the diaphragm, due to the large area of the diaphragm, a large thrust can be generated to push the diaphragm to move toward the end of the pressure. The vacuum boosting system controls the vacuum entering the booster pump while braking, moves the diaphragm, and uses the pusher on the diaphragm to assist the manpower to step on and push the brake pedal.

Therefore, when the engine is turned off, since there is no intake vacuum, there is no power, and the artificial force required for braking will be large. It should be noted here that there are many newcomers who think that if the engine is turned off, there is no brake. This is not right. The correct thing is that the engine is turned off, and the manual pedaling force required for braking becomes very large without assistance.
