Abstract
A clutch assembly includes a hub rotatable about an axis and at least partially surrounding a cavity, a damper ring within the cavity, able to revolve about the axis, rotatable relative to the hub, a spring, a friction disc, forced elastically by the spring into contact with the damper ring, and a second friction disc contacting the damper ring and providing a reaction to the force of the spring.
Claims14
A clutch comprising:
- a hub rotatable about an axis, having a radially extending arm and an axially extending arm at least partially surrounding a cavity;
- a damper ring within the cavity, radially inward from the axially extending arm, able to revolve about the axis, rotatable relative to the hub;
- a spring contacting the hub;
- a first friction disc adjacent to but spaced axially from the radially extending arm, forced elastically by the spring away from the radially extending arm into contact with the damper ring, and rotatable relative to the damper ring;
- a second friction disc contacting and rotatable relative to the damper ring and providing a reaction to a force produced by the spring.

- a first friction disc spaced axially from the radially extending arm forced by the spring away from the radially extending arm against a first axial side of the ring, and rotatable relative to the damper ring;
- a second friction disc contacting and rotatable relative to the ring at a second axial side of the ring with a reaction to a force produced by the spring.
