Abstract
A clutch assembly is disclosed that includes a hub, a damper and a pre-damper. A first pre-damper side plate is adjacent the damper and a second pre-damper side plate has a lug that extends radially outwardly and axially across the intermediate plate and the first pre-damper plate toward a first side plate of the damper that is adjacent the pre-damper. The lug is received in a notch defined by the first side plate of the damper to prevent relative rotation between the first side plate of the damper and the pre-damper. A method is disclosed for assembling the pre-damper and the damper on a hub. The pre-damper includes a radially and axially extending lug that is assembled to the notch in the damper to prevent relative rotation between the damper and the pre-damper.
Claims20
A clutch assembly comprising:
- a hub;
- a damper attached to the hub, the damper including first and second side plates disposed on opposite axial sides of a pair of friction plates having friction linings, wherein the first and second side plates and the friction plates are operatively connected by a plurality of damper springs for damping between the first and second side plates and the pair of friction plates;
- and
- a pre-damper attached to the hub adjacent the damper and attached to the hub, the pre-damper comprising an intermediate plate, a first pre-damper side plate disposed on a first axial side of the intermediate plate, and a second pre-damper side plate disposed on an opposite axial side of the intermediate plate,
- wherein the first pre-damper side plate and the second pre-damper side plate are operatively connected by a plurality of pre-damper springs,
- wherein the first pre-damper side plate is adjacent the damper,
- wherein the second pre-damper side plate comprises a lug that extends radially outwardly and axially across the intermediate plate and across the first pre-damper side plate toward the first side plate that is adjacent the pre-damper,
- wherein the first side plate of the damper defines a notch, and
- wherein the lug is received in the notch defined by the first side plate of the damper and the notch prevents relative rotation between the first side plate of the damper and the pre-damper.
