The auxiliary clamp body is an important component in the disc brake. A brake block is placed on the working surface of the auxiliary caliper body. The brake block is composed of a friction block with a small working area and a metal back plate. There are generally 2 to 4 brake blocks in each brake. The brake blocks and their actuating devices are installed in a caliper-shaped bracket that spans both sides of the brake disc.
The auxiliary clamp body made of QT600-3 material is produced by using a vertical boxless molding process, and the inner cavity contour shape is formed by the sand core. The product has stable size, small deformation, good consistency of product hardness, product spheroidization rate of more than 80%, uniform metallographic structure, good graphite shape, and good product processing performance.
Products are widely used in bus brake systems.
