Abstract

A freewheel for blocking or interrupting a torque transmission of a motor vehicle comprises a first ring configured for the input and/or output of a torque and a second ring that is arranged substantially coaxially to the first ring and configured for the output and/or input of the torque. The freewheel includes a plurality of first blocking elements, movable between a blocking position and a freewheeling position, for blocking the first ring with the second ring in a circumferential direction in the blocking position and for interrupting a torque transmission between the first ring and the second ring in the freewheeling position. A decoupler is coupled to the second ring or to the first ring for damping rotational irregularities. The decoupler has a housing, mounted on the first ring or the second ring via a housing bearing, for providing a restoring torque directed against the rotational irregularity. A brake element, which can act indirectly or directly on the second ring and/or the first ring, is provided for damping the movement of the first ring and/or the second ring. The brake element is connected indirectly or directly to the housing of the decoupler in a rotationally fix…
