Abstract
A clutch assembly includes an outer ring having an inner peripheral surface and an inner ring seated within the outer ring and having an outer peripheral surface. A plurality of rollers is seated between the inner and outer rings for selectively binding between the inner and outer peripheral surfaces to prevent rotation of the inner disc relative to the outer disc. At least one of the inner and outer disc includes an inner sleeve mechanically coupled to an outer jacket with an interference fit such that the inner sleeve is in compression and the outer jacket is in tension whereby the tensile hoop stress is reduced between the inner and outer rings upon the binding of the rollers between the surfaces.

A clutch assembly comprising:
- an inner ring having an inner bore and a continuous outer periphery defining a plurality of outer peripheral cam surfaces;
- an outer ring having an inner peripheral surface;
- a plurality of rollers seated between said inner and outer peripheral surfaces for selectively binding said inner and outer rings and preventing relative movement therebetween;
- and
- said outer ring including an outer jacket and an inner sleeve defining said inner peripheral surface, said outer jacket and said inner sleeve being mechanically coupled wherein tensile hoop stress in said outer ring is reduced by said outer jacket being mechanically coupled with said inner sleeve.
