Abstract
The inventive bearing arrangement for a device for activating a vehicle brake has a central threaded spindle (,) which is secured against torsion in a fixed housing (,) and which is arranged in such a way that it can be displaced up to a brake disk (,) of the vehicle and from thereon axially. The inventive arrangement is also provided with an inner ring (,) which concentrically surrounds the threaded spindle (,) together with roll bodies. Said inner ring (,) is coupled with a rotating rotor of an electromotor (,) at the front and is supported with the same in the housing (,) by an axial roller bearing and a radial roller bearing so that it can rotate. According to the invention, the axial roller bearing of the inner ring (,) is made up of a planetary gear with several roll bodies serving as planets. Said roll bodies are situated between the inner ring (,) and a bore wall (,) of the housing (,) which is axial to the inner ring (,). This reduces the friction losses of the axial roller bearing.
