Abstract:
1. A drive unit comprising a radial interior drive element ( 1 ) and a radial exterior drive element ( 18 ) as well as a free-wheel ( 15 ) arranged between the interior drive element ( 1 ) and the exterior drive element ( 18 ), wherein the interior drive element ( 1 ) and the exterior drive element ( 18 ) are axially displaceable in reference to one another, wherein the free-wheel ( 15 ) is for connecting the interior and exterior drive elements such that relative rotation between the interior and exterior elements is possible in a first rotational direction, wherein the free-wheel ( 15 ) is for rotationally locking the interior and exterior drive elements in a second rotational direction opposite the first rotational direction, and wherein at least one spring element ( 11 ), which is elastic in the axial direction, is fixedly connected to the side of the free-wheel ( 15 ) and to the radial interior drive element ( 1 ) at a first axial end of the drive unit.
