The working principle of vacuum booster is as follows:
1. The brake booster pump uses the principle of inhaling air when the engine is working, causing a vacuum on one side of the booster, creating a pressure difference relative to the normal air pressure on the other side. This pressure difference is used to enhance the braking thrust. Even if there is only a small pressure difference on both sides of the diaphragm, due to the large area of the diaphragm, a large thrust can still be generated to push the diaphragm toward the end with less pressure;
2. In the working state, the push rod return spring makes the brake pedal in the initial position. At this time, the one-way valve at the connection position between the vacuum tube and the vacuum booster is in an open state. Inside the booster, the diaphragm divides it into Vacuum air chamber and application air chamber. These two air chambers can be connected to each other. Most of the time, they are isolated from the outside world. The air chamber can be connected to the atmosphere through two valve devices;
3. When the engine is running, depress the brake pedal. Under the action of the push rod, the vacuum valve is closed. At the same time, the air valve at the other end of the push rod is opened. After the air enters (depressing the brake pedal produces a gasping sound (reason) will cause an unbalanced state of air pressure in the cavity. Under the action of negative pressure, the diaphragm is pulled toward one end of the brake master cylinder, and then drives the push rod of the brake master cylinder, which realizes the transfer of leg power. Further amplification capabilities.
