Abstract

A wrap spring clutch having a first component rotatable around a rotary axis, a second component rotatable around the rotary axis, and a wrap spring arrangement, which is held in a substantially rotation-proof manner on one of the two components relative thereto and is at connective rest or can be brought into connective rest on a circumferential surface of the other of the two components to establish a rotary connection between the first and second components. The wrap spring arrangement is at connective rest with a first spring section on a circumferential surface of the first component for torque transmission and is at connective rest with a second spring section on the circumferential surface of the other component.
