An adjustment drive for a motor-adjustable steering column for a motor vehicle includes a drive unit having a transmission in which there is mounted a drive wheel. The drive wheel can be driven to rotate about a drive axis and is in operative engagement with a transmission wheel which is mounted in the transmission so as to be rotatable about a transmission axis. The transmission has a drive module, which includes the drive wheel, and a transmission module, which includes the transmission wheel. The drive module and the transmission are connected to one another by a joining connection.

The present invention relates to a bearing arrangement (104) connectable to a shaft (102), the bearing arrangement comprising a bearing (105, 105′) comprising a plurality of rolling elements (110) arranged to rotate relative to an inner raceway (302) for said bearing arrangement; and a ring shaped contact element (114, 114′) having an extension in an axial direction thereof, the ring shaped contact element further comprising a first contact surface (402) adapted to face the plurality of rolling elements, wherein an inner diameter of the ring shaped contact element at the axial position of the first contact surface has a larger diameter in comparison to a diameter (412) of the inner raceway, such that a continuous radial gap (414) is provided in the circumferential direction between the ring shaped contact element and the inner raceway when the bearing arrangement is connected to the shaft, wherein the radial gap (414) is arranged to be provided in fluid communication with a lubricating flow channel (306) of the shaft when the bearing arrangement.

A drive train unit for a motor vehicle includes a housing and an input shaft rotatably mounted in the housing and arranged for attachment to an output of a transmission in a rotationally fixed manner. The input shaft has a first input shaft section and a second input shaft section that can move axially in relation to the first input shaft section. The drive train unit may include an electric machine arranged parallel to the input shaft, and a first clutch. The electric machine has a rotor and the first clutch arranged to connect the rotor and the input shaft for torque transmission in a shift position. The drive train may include an output shaft rotatably mounted in the housing and arranged for rotational coupling to a distributer transmission, and a second clutch arranged to connect the input shaft and the output shaft for torque transmission in a shift position.

In at least one implementation, a method of assembling gears into a housing of an automotive differential includes, selecting a thickness dimension of first and second pinion gear washers, and first and second side gear washers, locating a pair of pinion gears, a pinion shaft and a pair of side gears at least partially within an interior of the housing with the pinion gear washers between the housing and separate ones of the pinion gears, and the side gear washers between the housing and separate ones of the side gears. The thickness of the side gear washers may be a function of target side gear apex positions and relative to a pinion gear apex axis. The thickness of the pinion gear washers may be a function of target pinion gear apex positions residing along a pinion gear apex axis and relative to a side gear apex axis.

A method for assembling a component of a drive train is provided. The component includes at least a first part with a plurality of threaded holes and a second part with a corresponding number of through holes. The threaded holes and through holes each extend along an axial direction.

A vehicle transmission has a fixed housing, comprising a central part and a transversal wall, extending radially from the central part and a rotatable shaft. at least one bearing, radially interposed between the shaft and the housing, and coaxial with the shaft, comprising: an inner ring, seated in the housing; an outer ring, seated in the shaft; and tapered rollers. The inner ring is axially movable with respect to the housing to adjust an axial gap and/or a preload in a system. An adjustment device axially moves the inner ring, the adjustment device being in axial contact with the inner ring through openings of the transversal wall, the adjustment device being threadedly mounted on the housing.
