Brake unit with a non-metallic brake disc made of ceramic and a hub made of another material

Abstract

A brake unit having a brake disc of ceramic and a hub of a different material, which radially overlap one another with their mutually facing rims and are mechanically joined by a wreath-type rim of mounting bolts that axially penetrate the overlapping rims. The mounting bolts are uniformly included in the transmission of torque. Entrainment bores or slots provided in the brake disc are plastically lined with a metal or plastic sleeve, or the disc material is formed specifically to certain areas in this region as a plastically deformable C/C structure. A method is disclosed for manufacturing a partially ceramized molded article, in particular a brake disc having a C/C structure in the area of the entrainment bores or slots. A completely non-metallic brake unit and a method for its manufacture are also disclosed.
