The brake cylinder is mainly used to push the brake pads, the brake pads matcha brake drums, so that the speed of the vehicle is reduced or even stopped. It is an indispensable chassis braking part in the braking system.
After the brake is stepped on, the master cylinder generates thrust to press the hydraulic oil to the sub-pump, and the piston inside the sub-pump is moved by the hydraulic pressure to push the brake pads. The oil brake is composed of the brake master cylinder and the brake oil storage tank. They were connected to the brake pedal at one end and the brake hose at the other. Brake oil is stored in the brake master cylinder, and has an oil outlet and an oil inlet. When the brake is applied, the oil outlet opens and the oil inlet closes. Under the pressure of the piston of the pump body, the brake oil pipe is squeezed out of the oil pipe to flow to each brake cylinder to perform the braking function. When releasing the brake pads. The oil outlet in the brake master cylinder will be closed, and the oil inlet will be opened, so that the brake oil will return from each brake cylinder to the brake master cylinder, returning to the original state.
According to the brake cylinder manufacturer, the car brakes are divided into air brakes and hydraulic brakes. Heavy trucks use air brakes, and general cars use oil brakes. When you brake, when you step on the brake pedal, the brake master cylinder sends the brake fluid through the pipeline to each brake cylinder. The brake cylinder has a connecting rod that controls the brake shoes or pads. When braking, the brake oil in the brake oil pipe pushes the connecting rod on the brake cylinder, so that the brake shoe tightens the flange on the wheel to stop the wheel.
