How does the China brake chamber work?
The working principle of the China brake chamber is: when the vehicle brakes, compressed air enters the first air chamber through the air inlet, acts on the diaphragm, moves to the right against the compression spring, and generates braking force that acts on the gap and adjusts the arm to brake the wheel. When the pressure in the first chamber decreases, the compression spring pushes the diaphragm and push plate back into place. During parking brake, when the pressure in the second chamber is fully or partially deflated, the compression spring will brake the wheel through the piston and the push rod. When there is no pressure in the second chamber, the braking force is maximum.
Since the braking force of the China brake chamber comes from mechanical braking, that is, the compression spring force, the spring chamber can be used for parking brakes. When the brake is released, the pressure in the second chamber increases through the other port. Mechanical release mechanism: In an emergency, the double-chamber air chamber has a mechanical release device with a spring chamber. If the pressure on the other port is zero, use a wrench to loosen the screw to release the parking brake.
In summary, the advantages of the dual-chamber air chamber are as follows:
1. Due to the energy storage function of the double-chamber air chamber, the vehicle can maintain a good braking state when the vehicle is parked for a long time;
2. Due to the parking brake function, the parking brake is safer and more reliable;
3. When the tractor is separated from the trailer, the trailer can brake by itself and is in a good braking state.
How is the volume of China brake chamber calculated?
It refers to the diaphragm area of the air chamber, the front number refers to the diaphragm area of the drive chamber, the front number refers to the back refers to the area of the parking chamber diaphragm, and the unit is square inches.
What are the two main components of the China brake chamber?
The spring brake chamber is part of the car's braking system. It is generally installed on the drive axle of a car, and its role is to provide a braking torque for the car.
The combined spring brake air chamber is used to provide braking driving force for the wheel brakes. It consists of two parts: diaphragm cavity, used for service brake; spring cavity, used for auxiliary brake and parking brake. Among them, the feature of the spring cavity is that it has an over-travel function and is equipped with a mechanical release brake device.
The function of the brake air chamber is to convert the pressure of the compressed air into the mechanical force that makes the brake camshaft rotate to realize the braking action. The brake chamber is a clamp diaphragm type. The front and rear brake chambers are of different sizes, but the structure is basically the same.
China brake chamber: What does 30/30 in the brake chamber model mean?
It refers to the diaphragm area of the air chamber, the front number refers to the diaphragm of the drive chamber, and the back number refers to the diaphragm area of the parking air chamber, in square inches.
China brake chamber: What are the components of a car brake chamber?
The brake air chamber  is also called the sub-cylinder, and its function is to convert the pressure of compressed air into mechanical force to make the brake camshaft rotate, thereby realizing the braking action. The brake chamber is a clamp diaphragm type. The front and rear brake chambers are of different sizes, but the structure is basically the same, as shown in the figure. It is composed of an air inlet, a cover plate, a diaphragm, a support plate, a return spring, a housing, a push rod, a connecting fork, a clamp, and a bolt.
