As a Vacuum Brake Booster System Factory, share information with everyone. Gasoline engines can generate high vacuum pressure in the intake manifold, while diesel engines and gasoline direct injection engines need to be equipped with a vacuum pump to provide a vacuum source to meet the requirements of a vacuum assisted braking system. Vacuum Brake Booster System passenger cars and light commercial vehicles mainly uses hydraulic pressure as the transmission medium. Compared with the pneumatic brake system that can provide a power source, it requires a booster system to assist the driver in braking. The vacuum brake booster system is also called a vacuum servo brake system. The servo brake system is based on human hydraulic brakes and a set of booster devices provided by other energy sources to provide braking power. The braking system with human and engine power as braking energy. Under normal circumstances, its output working pressure is mainly generated by the power servo system, so when the power servo system fails, the hydraulic system can be fully driven by human power to generate a certain degree of braking force. The vacuum booster of the combination of the vacuum booster air chamber and the control valve generates thrust during work, and also acts directly on the piston push rod of the brake master cylinder as the pedal force.
Vacuum Brake Booster System
The vacuum booster is generally located between the brake pedal and the brake master cylinder. For ease of installation, it is usually combined with the master cylinder into a component. A part of the master cylinder penetrates into the vacuum booster housing. When the vacuum booster fails or there is no vacuum in the vacuum pipeline, the control valve push rod will directly push the diaphragm seat and the brake master cylinder push rod to move through the air valve, so that the brake master cylinder generates braking pressure, but the Force must increase.
The vacuum booster is a brake servo device in the brake system of light and passenger cars. It uses the vacuum generated by the gasoline engine to work or the vacuum generated by the vacuum pump installed in the diesel engine to amplify the brake pedal force by a certain proportion to promote the master cylinder The piston causes the brake master cylinder to generate hydraulically pressure, which causes the wheel brakes to generate resistance, thereby controlling the vehicle to decelerate or brake.
The vacuum booster is a kind of brake booster, used to assist the brake.
The brake booster is a brake booster widely used from light cars to medium cars. It can be roughly divided into vacuum booster, hydraulic booster and pneumatic booster.
Vacuum booster can be roughly divided into direct-acting vacuum booster and hydraulic vacuum booster. Because the direct-acting vacuum assist directly assists the pedaling force and the brake operation feeling is good, it is widely used in cars and small trucks, but because the pedaling force is directly used as an assisting force, it will be restricted by the installation space. The hydraulic vacuum booster uses the hydraulic pressure generated by the master cylinder to assist, so it can be installed at any position between the master cylinder and the wheel cylinder, but the brake operation feeling is generally worse than the direct-acting vacuum assist.
