Abstract

A clutch system includes a friction clutch, a ramp system, a pilot clutch, and an actuation element. The friction clutch is for transmitting torque between a torque-introducing element and a torque discharging element. The friction clutch includes a pressure plate. The system is for axially moving the pressure plate. The ramp system has an input ramp and an output ramp. The output ramp is rotatable relative to the input ramp to change an axial extent of the ramp system. The pilot clutch is for initiating rotation of the input ramp relative to the output ramp in response to a speed differential between the torque-introducing element and the torque-discharging element. The actuation element is arranged radially on the inside relative to the friction clutch and is at least partially covered by the friction clutch when viewed in a radial direction.
