A disconnect system for an all-wheel drive vehicle drive train is provided. The disconnect system includes a first torque transmitter, a second torque transmitter and a clutch selectively connecting the first torque transmitter and the second torque transmitter. The clutch includes an engagement section and an inner race and an outer race supporting the engagement section. The inner race is arranged to be forced against the engagement section to lock the clutch and moved away from the engagement section to unlock the clutch.

A wedge clutch, including: an inner race having a radially outermost surface sloping radially outward from a first axial side to a second side; an outer race located radially outward of the inner race; a wedge plate radially disposed between the inner and outer races, the wedge plate including a radially innermost surface sloping radially outward complementary with the radially outermost surface of the inner race; and an actuation assembly arranged to displace the inner race in the first axial direction to place the wedge clutch in a locked mode in which the inner race, the wedge plate and the outer race are non-rotatably connected and in the second axial direction to place the wedge clutch in a free-wheel mode in which the inner and outer races are rotatable with respect to each other.

A friction clutch of a multispeed transmission is provided, including an actuating sleeve which is seated on a shaft and is adapted to be shifted linearly along the shaft, a first friction clutch unit arranged in the axial direction on one side of the actuating sleeve, a second friction clutch unit arranged in the axial direction on the side of the actuating sleeve which is opposite the first friction clutch unit, the actuating sleeve producing a frictional fit in the first friction clutch unit in a first engaged state, and a frictional fit in the second friction clutch unit in a second engaged state. An electric drive of a vehicle having a 2-speed transmission and an electric motor, which is coupled via a friction clutch according to the disclosure, is also provided.

An electromagnetic clutch is specified, includes a shifting sleeve which is arranged on a shaft for joint rotation therewith and is linearly displaceable along the shaft between a first engaged position, a second engaged position and a disengaged position located between the engaged positions, a first clutch body and a second clutch body, which are axially spaced apart from each other and are each aligned coaxially with the shaft, each clutch body having an internal toothing, and a stator having a first and a second energizable coil. The shifting sleeve has a first toothing for engaging the internal toothing of the first clutch body in the first engaged position and a second toothing for engaging the internal toothing of the second clutch body in the second engaged position. The clutch furthermore includes a locking device which prevents the shifting sleeve from moving beyond the disengaged position in the direction of the further engaged position when the shifting sleeve is displaced out of an engaged position in the direction of the disengaged position. A method of actuating the clutch is also specified.
