Abstract:
Bearing arrangement for actuating a brake system comprising a central threaded spindle (2), which is arranged in a stationary housing (1), secured against rotation and arranged for axial displacement toward and away from a brake disc (3) of said brake, further comprising an inner ring (5) which, together with first rolling elements, concentrically surrounds the threaded spindle (2), said ring (5) being arranged for rotation in the housing (1) through a thrust rolling bearing that is constituted by a planet drive which comprises a plurality of second rolling elements forming planets that are arranged between the inner ring (5) and a bore wall (8) of the housing (1) coaxial to the inner ring (5), said inner ring (5) is aligned at one end on the same axis to a rotatable rotor of an electromotor and is additionally retained for rotation with this rotor in the housing (1) through a radial rolling bearing which is constituted by two needle roller bearings whose needle roller bushings (11) bear against the bore wall (8) and the first one of these is arranged adjacent to one end of an outer ring (10) of the thrust bearing and the second one of these is arranged adjacent to the other end of the outer ring (10) of the thrust bearing.
