Abstract
A freewheel clutch that has sprags, which are located between an inner locking track and an outer locking track and two sliding discs which each feature one inner axis adjacent to the inner locking track, one outer axis adjacent to the outer locking track as well as one middle section which connects the axes, and has an axial inwardly directed bending. The bending extends from the outer axis to the inner axis and preferably features a maximum embossing depth which is lower than the wall thickness of the middle section.

A freewheel clutch, comprising:
- an inner clamping track;
- an outer clamping track, radially outside of the inner clamping track;
- clamping bodies arranged between the inner clamping track and the outer clamping track;
- and
- two sliding disks between the inner clamping track and the outer clamping track, each of the two sliding disks having an inner leg bearing radially inward against the inner clamping track, an outer leg bearing radially outward against the outer clamping track, and a middle section connecting the inner leg and the outer leg, the middle section having two circumferentially continuous segments, an inner segment which adjoins the inner leg and an outer segment which adjoins the outer leg, the inner segment and the outer segment both extending at an angle radially toward each other and joining to form a bend, the bend extends axially inwardly between the outer leg and the inner leg, and wherein a maximum inclination of the middle section relative to a radial line running orthogonally to the clamping tracks is not more than 30°.
