Abstract: The invention relates to an electric drive unit for a motor vehicle, comprising an electric drive and a multi-stage transmission (6), which is connected downstream of the electric drive and which is arranged, alone or together with the electric drive, in a drive housing (4). The drive housing is composed of a housing shell (11), the interior (11a) of which annularly surrounds the transmission (6), and an end wall (12), which is formed integrally with the housing shell (11). The end wall is provided, at the center thereof, with a transmission opening (17) for the transmission output shaft (18) of the transmission (6). Cooling liquid is conducted through the drive housing in order to cool the components of the transmission.

Abstract: An apparatus (1) comprising hardware equipment (3) having hardware components (10) enclosed by a chassis (2) having a front side (2A) and a rear side (2B), and auxiliary equipment (5) movable within the chassis (2) along at least one transportation rail (7) with a non-linear trajectory extending in horizontal plane between a first position at the front side (2A) of the chassis (2) and a second position behind the hardware equipment (3) at the rear side (2B) of the chassis (2), wherein a part of the hardware components (10) is at least temporarily removable from the chassis (2) or movable within the chassis (2) to provide space (11) for moving the auxiliary equipment (5) within the chassis (2) along the at least one transportation rail (7) between the first and second position.

Abstract: A pinion shaft bearing arrangement including a pinion shaft, which is mounted by means of at least two rolling bearings in a pinion shaft housing, the pinion shaft bearing housing being a bearing cartridge, having running surface formed on the inner circumference for the rolling elements of the rolling bearings. The pinion shaft housing is sealed in the direction of the pinion shaft by means of a sealing element, and a first lubricant channel is provided in the region between the rolling bearings and a second lubricant channel is provided in the region in front of the sealing element.
