Howo spare parts Brake Chamber Diaphragm WG9000360601

Brake chamber, also known as brake cylinder, its role is to compress the air pressure into the brake camshaft rotation of the mechanical force, to achieve braking action. The brake chamber's two parts is clamped by the clamp . Althrough the brake chamber size is different, its structure is basically the same, it consists of air inlet, cover, diaphragm, support plate, return spring, shell, putter, connecting fork, clamp and bolts and other components. When the trucks brake, the air was forced into the brake chamber by the inlet, under the action of air pressure diaphragm deformation, push the putter, and drive the brake adjustment arm, turn the brake cam, the brake shoe friction plate pressed against the brake drum to produce a brake. 

Because it concerned with the the brake system, so the quality of the brake chamber is very important, if use inferior products, it is likely to cause the brake failure, and accident.
