A split shaft is disclosed. The split shaft includes a proximal shaft section having a first proximal shaft end and a second proximal shaft end. The first proximal shaft end is configured to couple to the first machine arrangement. The split shaft further includes a distal shaft section having a first distal shaft end and a second distal shaft end. The first distal shaft end is configured to couple to the second machine arrangement. The second distal shaft end is configured to engage with the second proximal shaft end to convey the drive power from the first machine arrangement to the second machine arrangement. The second proximal shaft end includes a first indicator, and the second distal shaft end includes a second indicator. Alignment of the first indicator and the second indicator conveys timing for the drive power.

An axle assembly that includes an axle housing, a differential carrier, and an electric motor module. The differential carrier that is mounted to the axle housing and rotatably supports a differential. The electric motor module is received inside the differential carrier and is operatively connected to and provides torque to the differential.

An axle assembly having an electric motor module, a drive pinion, and at least one rotor bearing assembly. The electric motor module may have a rotor. The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.

An assembly with a housing, a bearing, which is received in a bearing bore formed in the housing, and an annular compensation member. The housing and the compensation member are formed of materials having a larger coefficient of linear thermal expansion than a material from which the outer bearing race is formed. The compensation member is fixedly coupled to the housing and mounted about an outer bearing race of the bearing. The compensation member is configured to grow in a radial direction into contact with an inside circumferential surface of the outer bearing race when a temperature of the assembly increases from a first predetermined temperature to a second predetermined temperature.

An axle assembly with a carrier housing, an input pinion and a ring gear. The input pinion includes pinion gear teeth and is supported for rotation about a first axis relative to the carrier housing via first and second bearings that are disposed along the first axis on opposite sides of the pinion gear teeth. The ring gear includes ring gear teeth that are meshed to the pinion gear teeth and a third bearing supports the ring gear for rotation about the second axis relative to the carrier housing. The third bearing is disposed along the second axis on a side of the ring gear that is opposite the first axis.

An axle assembly having an electric motor module, a drive pinion, and at least one rotor bearing assembly. The electric motor module may have a rotor. The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.

The invention relates to an apparatus for supporting an intermediate shaft, such as an intermediate shaft of a gearbox. In an embodiment, the apparatus comprises at least one bearing part for supporting an intermediate shaft and having an outer surface with at least a section that is circumferential; at least one carrier part having an inner surface extending about the outer surface at a first distance from the bearing part; and at least one molded part for decoupling the carrier part from the bearing part, the molded part disposed between the inner surface and the outer surface, and the molded part being frictionally engaged with the inner surface and the outer surface. The invention provides a device that, among other things, can be manufactured cost-effectively.

A replaceable replacement spindle assembly for both drive (tractor) axles and trailer axles comprises a spindle and seal ring. The spindle is an elongate cylinder having inner and outer bearing surfaces and a threaded portion at one end. The seal ring is a short annular or tubular component having a circular opening sized to achieve an interference fit on a portion of the spindle adjacent the inner bearing surface. The interfering surfaces of the spindle and the seal ring are complementarily dimensioned and tapered so that the surfaces contact when the spindle is properly positioned in the seal ring. Adjacent the end of the spindle opposite the bearing surfaces and threads is an end region with features such as openings or a channel which receive complementary fasteners such as plugs, short bolts or a through bolt.

To provide a rear wheel braking device for a motorcycle that can reduce an unsprung mass and the number of pieces of components on the rear wheel side of a shaft drive type motorcycle. In a rear wheel braking device for a motorcycle transmitting a drive force of a power unit of a motorcycle to a rear wheel through a drive shaft that extends in a vehicle longitudinal direction, the drive shaft includes a propeller shaft that is connected to a rear end of an output shaft through a universal joint, the output shaft protruding to the vehicle body rear side from a case member of the power unit. A brake disk is attached to the output shaft, the brake disk being braked by a rear wheel brake caliper. The rear wheel brake caliper is fixed to a bracket that is arranged in the case member, and is disposed on the vehicle body upper side of the brake disk.

A rear-wheel drive shaft (1) includes a fixed type constant velocity universal joint (3), a plunging type constant velocity universal joint (2), and an intermediate shaft (4) coupling both the constant velocity universal joints to each other. A ratio (PCD.sub.BALL (f)/D.sub.BALL (f)) of a pitch circle diameter (PCD.sub.BALL (f)) of balls (33) of the fixed type constant velocity universal joint (3) to a diameter (D.sub.BALL(f)) of each of the balls (33) is set from 3.70 to 3.87. A ratio (PCD.sub.BALL(s)/D.sub.BALL(s)) of a pitch circle diameter (PCD.sub.BALL(s)) of balls (23) of the plunging type constant velocity universal joint (2) to a diameter (D.sub.BALL(s)) of each of the balls (23) is set from 3.3 to 3.6.
