How To Connect The Two Ports Of The Car Brake Chamber?

The spring brake chamber is part of the car brake system. It is generally installed on the drive axle of the car, and its function is to provide braking torque for the car. A part of the brake system of the spring brake chamber is generally installed on the drive axle of the car to provide the combined braking torque for the car. The spring brake chamber is used to provide the braking force for the wheel brake. It consists of two parts: a Diaphragm chamber for the service brake; a spring chamber for the auxiliary brake and a parking brake. Among them, the spring cavity part is characterized by the function of overtravel and is equipped with a mechanical release brake device.

How to connect the two ports of the car brake chamber?

The air brake method is mostly used in the handbrake system of medium and large vehicles. The handbrake system of this kind of car is usually in a constant braking state with a strong spring. When the vehicle is about to drive, the driver releases the handbrake. Only when a certain air pressure is reached can the spring be pushed open, that is, the handbrake is released before driving.

Working principle Because the working principle of the air brake system is the same as that of the ordinary air brake, here we focus on the working principle of the parking brake. First, explain the structure of the energy storage spring air chamber. The energy storage spring air chamber is a combination of the service brake air chamber and the parking brake air chamber. The service brake air chamber is on the bottom and the parking brake air chamber is on the top. The air vent of the brake air chamber is welded on the housing of the parking brake air chamber, and its channel is parallel to the airport joint channel of the parking brake air chamber. And communicate with the service brake air chamber with the hole parallel to the air chamber axis. The piston assembly of the service brake air chamber includes a piston body, a sealing ring, and a guide sleeve.

When the parking brake is applied, the push rod only pushes the piston, but when the service brake is applied, the piston does not move. Before the car starts, the joystick of the manual valve should be pulled back to the parking brake release position, so that the compressed air can be charged into the parking brake air chamber from the parking brake air storage tank, and the energy storage spring can be compressed to make the parking brake The piston gets back to the non-braking position, and the service brake piston also returns under the action of the return spring simultaneously. At this time, the parking brake is released and the car can start, but if the air pressure of the air storage tank does not reach the minimum safe value, it is impossible to compress the spring, so the car cannot start. advantage.
