The brake chamber, as an indispensable key component in the braking system of commercial vehicles and heavy trucks, has a basic structure including air chamber, piston, piston rod, spring and air chamber diaphragm. A deep understanding of the structure of the brake chamber is essential to master its working principle and carry out effective maintenance.
The air chamber is a key space in the brake chamber, which is mainly used to store gas. In the entire braking system, the air chamber plays an important role in storing gas and generating air pressure. Generally, the air chamber is made of materials such as metal or plastic, and has good sealing performance to ensure that the gas does not leak.
As an indispensable component in the brake chamber, the piston has the important responsibility of converting the air pressure in the air chamber into mechanical force. When the driver steps on the brake pedal, the gas in the air chamber is compressed, and the piston moves forward, applying pressure to the brake drum or brake disc, thereby achieving vehicle deceleration and stopping.
The piston rod connects the piston and the brake drum or brake disc, and transmits the movement force of the piston to the entire braking system. Generally, the piston rod is made of strong metal materials with excellent strength and wear resistance to ensure that it can withstand high pressure during braking.
As an indispensable and important component in the brake chamber, the spring is mainly used to maintain the position of the piston and maintain its stability. The spring is usually installed around the piston or on the piston rod. It has a certain elasticity and can provide appropriate support force when the piston moves to ensure the normal operation of the piston.
The air chamber diaphragm is a key sealing component in the brake chamber, which is used to effectively seal the air chamber to prevent gas leakage. The air chamber diaphragm is usually installed at the air inlet or exhaust port of the brake chamber. It has a certain elasticity and durability and can effectively prevent the leakage of gas in the air chamber.
