Abstract
An electric motor rotor for a hybrid module includes a rotor carrier, a piston carrier, and a tapered snap ring. The rotor carrier includes a first inner circumferential surface with an inner spline for receiving a first plurality of clutch plates, a second inner circumferential surface, radially outside of the first inner circumferential surface, a radial wall connecting the first inner circumferential surface to the second inner circumferential surface, and a groove with a conical wall. The piston carrier includes a radial outer ring installed between the groove and the radial wall. The tapered snap is ring installed in the groove and urges the piston carrier into contact with the radial wall.
