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.
Claims19
A wrap spring clutch, comprising:
- a first component rotatable around a rotary axis;
- a second component rotatable around the rotary axis;
- a wrap spring arrangement having a first spring section and a second spring section, the wrap spring arrangement being held on one of the first and second components in a substantially rotation-proof fashion so that the first spring section is one of at connective rest and bringable into connective rest on a circumferential surface of the first component for torque transmission, and the second spring section is one of at connective rest and bringable into connective rest on a circumferential surface of the second component so as to establish a rotary connection between the first and second components;
- disengagement means connected to the wrap spring arrangement for selectively establishing and eliminating action of the wrap spring arrangement on the second component, the disengagement means including an annular disengagement element rotatable around the rotary axis so as to establish and eliminate the act of the wrap spring arrangement on the second component;
- operating means for operating the disengagement element, the operating means including an operating organ movable by a disengagement force production device in a direction of the rotary axis so that an activation surface of the operating organ pressurizes an activation section of the disengagement element;
- and
- rotary disconnection bearing means arranged between the operating organ and the disengagement force production device for rotary disconnection of the disengagement force production device and the operating organ.
