摘要

The pre-stressed unit (1) has two chute disks (2,5) that form multiple ramp contours (8). An inner ramp contour (8a) and an outer ramp contour (8b) are provided in one side of an annular surface of the ramp disks. Multiple rolling elements (3) are arranged between both the ramp disks, where a retaining clip holds one rolling element in a rotating manner. The retaining clip engages the ramp disks from behind, so that an axial force pre-stresses one ramp disk against the other ramp disk.
