Abstract
A freewheel arrangement, in particular for a crank-CVT, which has an inner ring, an outer ring, which can be rotated relative to the inner ring in at least one direction of rotation and which is arranged radially around the inner ring, several cam-shaped clamping elements, which have a foot area and a head area and are arranged between the inner ring and the outer ring in a cage and can be acted on in the direction of the inner ring by a radially inwardly directed spring force of a spring. The spring is a double-acting torsion spring, which simultaneously acts on the head area and the foot area of adjacent clamping elements and presses the clamping elements radially inward.
