Abstract
A prestressing unit which has a first ramp disk and a second ramp disk. Ramp contours are formed in one side of an annular face of the ramp disks. In the prestressing unit, the rolling bodies ascend and/or descend on the ramp contours as a result of rotational pivoting of one of the ramp disks in relation to the other ramp disk about an axis. The ramp contours are each formed as a single-part running face for the rolling bodies. The running face is inclined with respect to the axis.
Claims15
A prestressing unit having a first ramp disk and a second ramp disk, a plurality of ramp contours are formed in one side of an annular face of the first ramp disk and the second ramp disk rolling bodies are arranged between the ramp contours of the first ramp disk and the second ramp disk in such a way that, in the prestressing unit, the rolling bodies rise and/or fall on the ramp contours as a result of rotational pivoting of at least one ramp disk in relation to the other ramp disk about an axis wherein single-piece running faces are formed in the ramp contours for the rolling bodies, and the running faces are inclined with respect to the axis.
