Freewheel and freewheel arrangement

摘要

A freewheel (4) having a first running ring (28), a second running ring (30), a clamping gap (32) formed between the first and second running rings (28, 30), and at least one clamping element (34) in the clamping gap (32), the clamping gap (32) being assigned a side wall (40; 52) on which the at least one clamping element (34) can be or is supported. A side (60; 64) of the clamping element (34) which faces toward the side wall (40; 52) and/or that side (68; 72) of the side wall (40; 52) which faces toward the clamping element (34) is provided with a friction-reducing, wear-reducing and/or corrosion-reducing coating (62, 66; 70, 74) or surface treatment.

1. A freewheel arrangement comprising a freewheel having a first running ring, a second running ring, a clamping gap formed between the first and second running rings, the first running ring defining an outer side of the clamping gap, the second running ring defining an inner side of the clamping gap opposite the outer side, and at least one clamping element in the clamping gap that has a clamping element side, a side wall defining an axial side of the clamping gap that extends from the inner side to the outer side delimiting the clamping gap, and on which the at least one clamping element is supported, wherein the clamping element side faces toward the side wall and wherein each of the clamping element side and the axial side is provided with a layer treated to reduce hysteresis of the freewheel wherein contact between the clamping element and the side wall is through contact of the two respective layers on the clamping element side and the axial side.
