Abstract
A clutch has an outer housing and an inner housing arranged coaxially with respect to one another to support a plurality of first and second alternating, interiorly arranged, radially extending, friction members for axial movement between engaged and disengaged positions. The outer housing can have a longitudinally extending cylindrical side wall and a radially inwardly extending end wall. A plurality of longitudinally extending, teeth-receiving notches can be formed at evenly angularly spaced locations along the cylindrical side wall. Each notch can have radially inwardly bent wall portions extending longitudinally to define teeth-receiving sidewalls of the outer housing. The inner housing assembly can have a hub and an elongate sheet metal strip having bent tabs and evenly spaced corrugations stamped along an entire longitudinal length. The strip can be wrapped around to form a continuous, generally cylindrical, corrugated ring with inwardly extending bent tabs connected to the hub.
