A drive unit for an electric vehicle has at least one electric machine, a multi-speed transmission, and a distributor device. The rotor of each electric machine is connected to an associated input shaft of the multi-speed transmission. The multi-speed transmission is connected on the output side to the distributor device with different transmission ratios being selectable in the multi-speed transmission. In addition, a drive power introduced into the distributor device can be distributed to at least two outputs of the distributor device. In order to provide a compact drive unit for an electric vehicle with permanent all-wheel drive or selectable all-wheel drive, the distributor device can be used to provide a longitudinal distribution of the introduced drive power in that the outputs of the distributor device are each provided for coupling to a respective drive axle of the electric vehicle.

An assembly for an electric vehicle includes an input shaft extending along a first axis and an electric motor rotatably coupled to the input shaft and co-axially aligned with the first axis. The assembly also includes an intermediate input shaft extending along a second axis and rotatably coupled to the input shaft. The assembly also includes an output shaft extending along the second axis and spaced from the intermediate input shaft along the second axis. The assembly further includes a planetary gearset rotatably coupled to the intermediate input shaft and to the output shaft, and co-axially aligned with the second axis.

A gearbox includes: an input shaft; a first output shaft; a second output shaft; a first planetary gearset; and a second planetary gearset connected to the first planetary gearset. The input shaft, the first and second output shafts, and the first and second planetary gearsets are configured such that a torque introduced via the input shaft is converted and distributed in a defined ratio to the first and second output shafts, so as to prevent formation of a sum torque. The first planetary gearset is configured as a minus planetary gearset, and the second planetary gearset is configured as a plus planetary gearset.

A vehicle stalactite passive lubrication system includes a drive unit having an electric motor and a gear. A sump has a sump extension. A lubricant is collected in the sump for gravity flow into the sump extension. A stalactite member is fixed to the drive unit and is positioned above an element to be filled with a fluid, lubricated or cooled. The stalactite member is directed downwardly toward the sump with the lubricant splashed by gear rotation collected on neighboring walls and the stalactite member and directed downwardly by gravity into the sump or target element. The stalactite member includes: a drip edge oriented at an angle to a horizontal plane; and a tip defining an end of the drip edge. The angle is selected to direct the lubricant to discharge off the stalactite member at the tip as a lubricant stream into the sump or target element.

A motor vehicle transmission system includes a reduction device having at least an output shaft including a first gearwheel and a second gearwheel. A differential drive device is configured to distribute the torque from the reduction device to two half-shafts. The differential drive device includes a coupling device which, in a coupled position, transmits torque between a first element and a second element of the differential drive device, the coupling device further including an actuator. A radial plane, orthogonal to the axes X and W, passes through the first gearwheel and through the coupling device.

A connection means is provided which connects a clutch part of the friction clutch to a clutch part of the positively-locking clutch.

Systems and methods for an electric drive axle are provided. In one example, the electric drive axle may include an electric motor-generator rotationally coupled to a gearbox having a one-way clutch mounted on an output shaft and operable in an engaged configuration and a disengaged configuration, where in the engaged configuration, the one-way clutch transfers rotational energy from the output shaft to an output gear rotationally coupled to a plurality of drive wheels.
