摘要

Motor vehicle wheel disc (2), mfd. as deep-drawn light metal sheet or as casting, has a bell-shaped brake support (3) fastened on the inside, carrying a brake disc (10) with friction coating on the outer circumference. The disc is freely displaceable in the axial direction and is pressed on the inner face of the wheel disc by a solenoid stator (16) with axially displaceable ring armature (17) via a spring steel plate (17). ADVANTAGE - Reduced weight, electrically controllable.
