Systems and methods are presented herein for providing an integrated disconnect. The integrated disconnect may be used within a drive unit. The integrated disconnect comprises an output gear having a cavity. A torque transfer adapter is arranged within the cavity. A clutch body is also arranged within the cavity. The clutch is actuatable through the output gear by an actuator to engage and disengage the clutch with the torque transfer adaptor. The actuator is located external to the cavity.

A dual clutch assembly comprises a rotatable second input shaft that surrounds and is concentric with a rotatable first input shaft. A rotatable hub surrounds the first input shaft. A first and a second clutch rotor are connected to the rotatable hub. The first clutch rotor comprises a pulley coupling and a clutch surface. The second clutch rotor comprises a clutch surface. A stationary electromagnetic assembly is mounted between the first clutch rotor and the second clutch rotor. A first armature assembly is coupled to the first input shaft and is configured to couple to the first clutch surface of the first clutch rotor in response to a first electromagnetic signal. A second armature assembly is coupled to the second input shaft and is configured to couple to the clutch surface of the second clutch rotor in response to a second electromagnetic signal.

A clutch assembly for a transmission having a gear radially supported relative to a shaft in which the clutch assembly includes a clutch plate rotationally coupled to the shaft. The clutch plate further includes an engaged state whereby a surface of the clutch plate abuts a surface of the gear to rotationally couple the gear to the shaft and a disengaged state whereby the clutch surface is spaced from the gear surface to rotationally uncouple the gear and the clutch plate. A transmission assembly includes a first shaft, a second shaft, and a plurality of gears interconnecting the first shaft and the second shaft such that each gear of the plurality of gears is radially supported by one of the first and second shafts. The transmission assembly can further include a plurality of the clutch assemblies.

The present disclosure provides a double clutch assembly and a device for assisting an actuator of the double clutch. The device applies an assistance force to the actuator upon an operation of the actuator. In particular, the double clutch assembly includes first and second actuators which engage or disengage first and second clutches, respectively. The device includes: an elastic member to apply an elastic force; a first transfer portion to transfer the elastic force of the elastic member to the first actuator; and a second transfer portion to transfer the elastic force of the elastic member to the second actuator.
