Abstract

A brake unit has a ceramic friction ring connected directly to a wheel hub by fastening bolts or by a spline shaft connection. To ensure good heat insulation between the friction ring and the hub and to achieve uniform torque transmission between the friction ring and the hub, the contact area between the friction ring and the fastening elements of the hub is provided with a plastically deformable heat-insulating layer.
