What is the Main Function of the Brake Chamber

When the car brakes, the air enters the brake air chamber from the air inlet, deforms the diaphragm under the action of air pressure, pushes the push rod, and drives the brake adjustment arm, rotates the brake cam, and removes the brake shoe friction plate. Press against the brake drum to brake.

The braking force of the diaphragm-type air chamber push rod is proportional to the input air pressure; the parking brake sub-chamber is a braking device that uses spring energy storage and air release. The inflation pressure enters the pressure air chamber through port 12, and generates a force acting on the piston. 

When the pressure is greater than 0.65MPa, the force acting on the piston is greater than the preload force of the spring, the piston goes up to the limit, and the brake is released; When the air is completely emptied, the spring pushes the piston down and pushes the main brake push rod to produce braking.

 The braking strength is related to the spring preload; when the air pressure in the pressure chamber is lower than 0.65MPa, the braking force generated by the sub-chamber is inversely proportional to the air pressure value. , so emergency braking can be implemented.

What is the main composition of the brake chamber

The brake chamber is mainly composed of a housing, a piston, a return spring, an exhaust valve and an air inlet valve.

The housing is made of cast iron or steel. It contains the mounting flange for attaching the chamber to the axle housing or frame, and the port for connecting the air line to the chamber. The piston is attached to the pushrod, and its function is to apply pressure to the diaphragm when actuated by the pushrod. The return spring returns the piston to its original position when released by the pushrod. 

The exhaust valve opens to allow air pressure to be released from behind the diaphragm when actuated by the pushrod, and closes when released by the pushrod. The air inlet valve opens to allow air pressure into the chamber when actuated by atmospheric pressure, and closes when atmospheric pressure is removed.

What is a brake chamber

A brake chamber is a housing that contains the working parts of an air brake system. The chamber is filled with air, which applies pressure to the brakes when released. The amount of air pressure in the chamber determines how much force is applied to the brakes.

In a vehicle, the brake chamber is a housing for the wheel cylinders or calipers. The brake chamber contains the pistons that push the brake shoes or pads against the rotating drum or disc.

A brake chamber is a housing that contains the parts of an air brake system that create pressure. The pressure in the brake chamber is what activates the brakes.

The main application areas of the brake chambe
