Abstract
A hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine includes an electric motor including a rotor and a stator for driving the rotor, a torque converter downstream of the electric motor, and a rotor input clutch including a piston and at least one clutch plate. The piston is configured for being pressed in a first axial direction into the at least one clutch plate via a pressure increase of fluid in an apply chamber. The hybrid module also includes a compensation chamber assembly. The compensation chamber assembly and the piston define a compensation chamber radially offset from the apply chamber. The compensation chamber assembly is configured for applying a force on the piston in a second axial direction opposite the first axial direction via a pressure increase of fluid in the compensation chamber.
