An electric machine with a stator, a rotor, and a fluid cooling device. The rotor is supported by a rotor shaft and a first bearing arranged at a bearing shield. The fluid cooling device has a cooling tube secured to a carrier element in fluidic communication with a fluid input and output and extends inside a recess of the rotor shaft while forming an annular space. A sealing element is provided between the rotor shaft and the carrier element, which prevents fluid passage into a spatial region of the electric machine outside of the sealing region. A second bearing is axially spaced apart from the first bearing is between the rotor shaft and a second bearing shield for supporting the rotor. The rotor core extends in a space between the first bearing and second bearing, and the recess extends inside the rotor shaft axially to the second bearing.

Electric machine having a fluid cooling device

A drivable axle, in particular a rigid axle, is provided for a motor vehicle the axle has a differential gear, at least one gear bearing, at least one axle tube, and at least one axle shaft. The differential gear features a volume (V) for lubricant separate from the axle tube. The differential gear is sealed at the axle tube by using a gap-type seal.

Driven axle for a motor vehicle

A drive train arrangement for a vehicle comprising a main transmission and a transfer box which are both housed within a transmission housing. The transfer box comprises a drive output which is connected to a rear axle differential transmission and connectable, by a torque transmission element and a connecting shaft, to a front axle differential transmission. The connecting shaft is arranged at a predetermined angle relative to the drive output shaft of the main transmission. The end of the connecting shaft, facing toward the front axle differential transmission, is actively connected to the front axle differential transmission. The front axle differential transmission is fixed to the vehicle by at least one adaptor device allowing the front axle differential transmission to be adapted to a variety of arrangement positions along the rotation axis of the connection shaft.

Drive train arrangement for a vehicle

A lockable differential gear having an integral differential gear housing (). The differential gear housing () has a plurality of apertures () located opposite one another. A number of the internal parts of the differential gear are mounted, during installation, within the differential gear housing () by passing through one of the plurality of apertures () during the assembly process. The plurality of apertures () generally remain open following the assembly process.
