The brake wheel cylinder is one of the necessary accessories on the car. Do you know how it works? The following brake wheel cylinder manufacturers will give you a brief introduction.
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.
We all know that a trailer is more difficult to drive than a car, so what's the difference when the trailer brake cylinder works?
Driven by the air pump through the engine, the air is compressed into high-pressure gas and stored in the air storage cylinder. One of the air storage cylinders can be connected to the brake master cylinder through the pipeline. The brake master cylinder is divided into upper and lower air chambers, and the upper air chamber controls the rear wheel. The lower air chamber controls the front wheels. When the driver steps on the brake pedal, the upper air is first opened, and the high-pressure gas of the air tank is transmitted to the relay valve. Push the control piston of the relay valve out, and the gas of another air tank can The relay valve is connected to the two rear brake cylinders. The push rod of the brake cylinder is pushed forward, and the cam is rotated by an angle through the adjusting back. The cam is eccentric, and the brake shoe is stretched and friction is generated while rotating. Achieving the effect of braking.
