Actuator for a vehicle brake, especially a disc brake

摘要

A shaft (34) is supported in the bottom (22) of a casing (20) and is rotatable for mechanical brake application. A ramp assembly (40) which is fixed to the casing and designed as an annular plate is supported on the bottom (22) around the shaft (34) and prevented from rotating by an off-center twist stop (42), and it is centered in the casing (20) in a way bypassing the shaft (34). Moreover, a rotatable ramp assembly (50) is arranged inside the casing (20) so as to be axially displaceable and is connected to the shaft (34) for torque transmission. The rotatable ramp assembly (50) is supported in such manner on the ramp assembly (40) which is fixed to the casing that it converts torque applied to it by the shaft (34) into an axial actuating force (B).
