A differential case (23) is therein provided with a plurality of rotating discs (38) that are spline-coupled to an outer peripheral side of aright side gear (35), and a plurality of non-rotating discs (39) that are respectively arranged between the respective rotating discs (38) and are non-rotatable relative to the differential case (23) and are movable in a left-right direction. A pressure ring (43) that presses the non-rotating discs (39) toward the rotating discs (38) is disposed between a right retainer (41) positioned in the right side gear (35)-side and the non-rotating disc (39). The right retainer (41) is therein provided with a piston accommodating part (41D) in a position facing the pressure ring (43) in the left-right direction. The piston accommodating part (41D) is therein provided with a piston (46) that is displaced by hydraulic pressure to press the non-rotating discs (39) against the rotating discs (38) through the pressure ring (43).

A spacer for coupling a wheel to a rotary output of a vehicle, the spacer including two connectors fixed relative to a respective first and second end of the spacer, the connectors each having a matching first array of fittings to engage a rim of the wheel, whereby to allow wheel gauge adjustment by disconnecting the wheel from a first one of the connectors, sliding the wheel along a body of the spacer and connecting the wheel to a second one the other connectors. The invention also relates to a method of adjusting wheel gauge on the spacer including releasing a wheel from one of the connectors, sliding the wheel along the body of the spacer and attaching the spacer to the other connector. The invention also relates to a spacer for supporting a wheel relative to a rotary output of a vehicle, the spacer being formed of modular sections that are separately attached by fasteners that connect only between adjacent sections to allow for independent addition and removal of sections to vary the length of the spacer.

The present disclosure relates to an axle beam, in particular an axle bridge, for a motor vehicle, preferably a commercial vehicle. The axle beam has a first axle beam shell and a second axle beam shell which is connected, in particular welded, to the first axle beam shell in order to configure a tubular body. The tubular body has an inner circumferential face with a plurality of flat sections which form a non-round cross section of the tubular body. The axle beam has a reinforcing component which has a non-round cross section, is arranged within the tubular body, and bears at least partially against the flat sections of the inner circumferential face of the tubular body.
