How are the housing and cover of the Brake Chamber connected and ensured to be airtight?



Industry News

The Brake Chamber is a key component in the brake system, and its structural design and material selection are important. The housing and cover of the Brake Chamber are usually made of high-strength, corrosion-resistant stamped steel plates. This material has good rigidity and toughness, can withstand the impact of high-pressure gas, and maintain the shape and size of the chamber. The housing and cover are fastened by clamps and bolts to form a closed space. This connection method is not only firm and reliable, but also easy to repair and replace.
The cloth-reinforced rubber diaphragm is one of the core components in the Brake Chamber. It is located between the housing and the cover, dividing the chamber into two independent parts. One side of the diaphragm is connected to the cover, and the other side maintains a certain gap with the housing so that it can be deformed under the action of air pressure. The diaphragm is usually made of cloth-reinforced rubber, which has good elasticity and wear resistance, and can withstand frequent deformation without cracking or deformation.
The sealing between the diaphragm and the housing and cover is crucial to ensure that the air pressure can be smoothly transmitted to the push rod and prevent gas leakage. Therefore, during the manufacturing process, the size and shape of the diaphragm, as well as the matching clearance between it and the housing and cover, need to be strictly controlled.
The push rod is a bridge connecting the diaphragm and the brake adjustment arm, which converts the deformation of the diaphragm into the rotational movement of the brake adjustment arm. The push rod is usually made of high-strength steel to ensure that it can withstand sufficient pressure and torque.
The connecting fork is located at the other end of the push rod and is used to transmit the movement of the push rod to the brake adjustment arm. The design of the connecting fork needs to ensure a firm connection with the brake adjustment arm and allow a certain angle adjustment to meet the needs of different vehicle models and braking systems.
The brake adjustment arm is another key component in the braking system, which is responsible for converting the movement of the push rod into the opening and closing of the brake shoe. The brake adjustment arm is usually made of high-strength steel and is equipped with an adjustment device to adjust the brake clearance when necessary. The brake cam is located at the end of the brake adjustment arm and is used to convert the rotational movement of the brake adjustment arm into the opening movement of the brake shoe. The design of the brake cam needs to ensure close contact with the brake shoe and be able to generate sufficient braking force under the action of air pressure.
The return spring is located between the diaphragm and the housing or between the push rod and the brake adjustment arm, and is used to return the diaphragm and push rod to their initial positions when the brake is released. The selection and installation position of the return spring need to be designed according to the specific requirements of the brake system. The return spring is usually made of high-strength, corrosion-resistant spring steel to ensure that it can withstand frequent deformation and restoring forces.
