Patent ID: 7870940

Claim:
A frictionally engaged free-wheel clutch comprising an exterior ring ( 1 ), an interior ring ( 2 ) approximately concentric in reference thereto, and several clamping bodies ( 6 , 21 , 23 ), which are rotationally asymmetrical clamping bodies or clamping rolls, arranged between the interior ring and the exterior ring, which block a rotation of the interior ring relative to the exterior ring in one direction and release it in the other direction, the clamping bodies ( 6 , 21 , 23 ) and/or running paths ( 3 , 4 ) of the interior ring and the exterior ring are provided with a friction increasing coating, wherein for the clamping bodies comprising the rotationally asymmetrical clamping bodies ( 6 , 21 ) with a profile geometry and for the clamping bodies comprising the clamping rolls with a profile provided on the interior or exterior rings, a clamping angle progression in reference to respective clamping surfaces ( 8 , 9 , 24 ) has a maximum clamping angle tan ε>0.12, and an increasing branch of a curve of the clamping angle begins at tan ε≦0.05 and inclines at least to approximately 0.25.
