Abstract
A torque transmitting system includes a case, first and second clutch plates, and a ramp member that is selectively rotatable about an axis and that defines a ramp surface. The system also includes an electric motor having a motor housing, wherein the case is rotatable relative to the housing about the axis. The motor is configured to selectively apply torque to rotate the ramp member. The system additionally includes a roller element mounted with respect to the case and contacting the ramp surface. The ramp surface is configured such that, when the ramp member is rotated about the axis, the roller element exerts a reaction force on the ramp surface that urges the ramp member to move in a first axial direction and thereby transmit the reaction force to the clutch plates. A transmission assembly including the above described torque transmitting system is also disclosed.
