摘要： A drive assembly for a motor vehicle includes a housing having a transmission housing chamber, a reservoir, and a clutch housing chamber. At least one of the transmission housing chamber or the clutch housing chamber are fluidically connected to the reservoir. A transmission is disposed in the transmission housing chamber. A clutch is disposed in the clutch housing chamber. The clutch is drivingly connected to the transmission. An actuator has an actuating element engaged with the clutch. The clutch is moveable by the actuating element between a disengaged position and an engaged position. A valve is operatively connected to the actuating element of the actuator to allow lubricant flow from the reservoir to at least one of the transmission housing chamber and the clutch housing chamber when the clutch is in the engaged position and to prevent lubricant flow from the reservoir when the clutch is in the disengaged position

摘要： An actuator assembly comprises a rotatably drivable drive gear; a locking ring which is rotatably mounted in a stationary housing and is drivingly connected to the drive gear, wherein the locking ring is rotatable from a first rotational position into a second rotational position against a rotation stop; wherein at least one friction face pairing is provided in the power path between the drive gear and the locking ring, via which a torque can be transmitted to the locking ring by frictional forces; a first ramp ring drivable by the drive gear and a second ramp ring, which are axially supported against each other and are configured to convert rotary movement into axial movement; wherein the first ramp ring, after the locking ring has reached the rotary stop, can be further rotatably driven by the drive gear.

摘要： An electric drive arrangement for a vehicle includes a housing. The electric drive arrangement includes an electric machine with a stator connected to the housing and a rotor with a rotor shaft rotatably supported in the housing. The electric drive arrangement includes a transmission to transmit a rotary movement from the rotor shaft to drive a driveline of the vehicle. The electric drive arrangement includes a hydraulic circuit for circulating a fluid to cool and lubricate the electric machine and the transmission.

摘要： A drive torque of an electric motor for driving a driveline included in a driveline assembly of a motor vehicle can be controlled as a function of the vehicle speed in such a way that, when the vehicle speed is below a predetermined threshold value, the electric motor is controlled in a high torque mode and, when the vehicle speed is above the threshold value, the electric motor is controlled in a low torque mode.
