  • Patent number: 10458491
    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.

  • Patent number: 10428880
    Abstract: A clutch system includes a friction clutch and a ramp system. The friction clutch is a multiplate clutch, for example, for transmitting a torque between a torque-introducing element (i.e., an engine drive shaft) and a torque-discharging element (i.e., a transmission input shaft). The ramp system includes an input ramp, an output ramp, a pilot clutch, an actuation element, and a freewheel. 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 when there is a differential speed between the torque-introducing element and the torque-discharging element. The actuation element is for actuating the pilot clutch.

  • Publication number: 20180091010
    Abstract: An electric motor for a hybrid drive of a vehicle comprises a rotor and a stator. The stator surrounds the rotor and the rotor is fastened to a rotor carrier. A rotor laminated core of the rotor is connected to the rotor carrier by a tongue-and-groove connection and a transverse interference fit. To form the transverse interference fit, the rotor laminated core may have, for bracing on the rotor carrier, a smaller radius than the rotor carrier.
