Abstract
A clamping element freewheel including an inner ring and an outer ring that can be rotated relative to the inner ring in at least one rotational direction. A cage for clamping elements is between the inner ring and the outer ring, with a plurality of clamping elements. The clamping elements are pivotable between a clamping position, in which they prevent relative rotation between the inner and outer rings, and a release position, in which they enable relative rotation between the inner and outer rings. A clamping element preload is provided to preload the clamping element radially inwardly and in the clamping position direction. The clamping element preloading is provided by springs that are configured separately for each clamping element.
