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.

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 side plates and the friction plates are operatively connected by a plurality of damper springs for damping between the side plates and the friction plates;
- and
- a pre-damper attached to the hub adjacent the damper and attached to the hub, the pre-damper having an intermediate plate, a first damper side plate and a second pre-damper side plate disposed on opposite axial sides of the intermediate plate that are operatively connected by a plurality of pre-damper springs, wherein the first pre-damper side plate is adjacent the damper and the 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 the first side plate that is adjacent the pre-damper, and wherein the lug is received in a notch defined by the first side plate of the damper that prevents relative rotation between the first side plate of the damper and the pre-damper.
A method of assembling a pre-damper and a damper to a hub, comprising:
- providing a hub;
- assembling a damper that includes a first side plate that defines a notch;
- assembling the damper to the hub;
- assembling a pre-damper that includes a spring cover that has a radially and axially extending lug;
- assembling the pre-damper to the hub after the damper is assembled to the hub;
- and
- securing the lug into the notch.
