Abstract: Locking differential systems, vehicles and methods are provided. An electric vehicle includes an electric motor including a stator and a rotor, wherein the rotor is configured to rotate about a rotor axis; a rotor shaft connected to the rotor for rotation about the rotor axis; a differential located within the rotor shaft; a first input shaft connected to first side of the differential; a second input shaft connected to second side of the differential; a locking system configured to selectively lock rotation of the first input shaft to rotation of the rotor shaft; a control system configured to determine when to lock rotation of the first input shaft to rotation of the rotor shaft; and an actuation system configured to operate the locking system to lock rotation of the first input shaft to rotation of the rotor shaft.

Abstract: A friction clutch assembly for an automatic transmission is provided. The friction clutch assembly is configured to move between an applied position and a released or disengaged position. A plurality of clutch plates may include friction plates and interleaved reaction plates, plus an apply plate and a backing plate. A separator feature is disposed adjacent to at least one of the reaction plates, the friction plates, the apply plate, and the backing plate. At least one of the reaction plates, the friction plates, the apply plate, and the backing plate defines a passage configured to allow fluid to flow through the friction clutch assembly and around the separator feature.
