A vehicle drive unit (11) includes a spindle (12) on which a female spline portion (12G) is formed, a wheel (15) disposed on an outer peripheral side of the spindle (12), wheel bearings 17, 18 that rotatably support the wheel (15) in relation to the spindle (12), an electric motor (21) located on an axial one side of the spindle (12), a shaft (22) connected to an output shaft (21B) of the electric motor (21), a planetary gear reduction device (25) disposed between the shaft (22) and the wheel (15), and a shaft bearing (46) that rotatably supports the shaft (22) in relation to the spindle (12). A retainer (42) retaining the shaft bearing (46) is disposed on an inner peripheral surface side of the spindle (12), and a male spline portion (42E), which is spline-coupled to a female spline portion (12G) of the spindle (12), is disposed on the retainer (42).

The present disclosure generally relates to wheel adapters for center pivot irrigation systems. In one example embodiment, a dual-wheel adapter generally includes a spacer. The spacer includes a body having first end portion and a second end portion. A first flange is disposed at the first end portion of the body and oriented axial to the body. The first flange configured to align with a first wheel of a pivot tower and to secure the spacer to the pivot tower. A second flange is oriented axial to the body and disposed at the second portion end of the body. The second flange is configured to align with a second wheel and to secure the second wheel to the pivot tower.

Vehicles are disclosed that are configured to carry loads in a stabilized manner, such that the load is maintained in a substantially constant position or orientation relative to a predetermined reference point or frame even as the vehicle moves. A stabilization controller in such a vehicle receives information about movement of the vehicle relative to the reference point or plane from one or more sensors on the vehicle, and uses the information to control one or more movable objects by which the load is secured to the vehicle so as to maintain a relatively constant relationship between the load and the reference point or plane.

A powered axle for a work vehicle with a dual wheel arrangement includes an axle housing, an axle hub mounted to the axle housing, and an output hub having opposite axial ends supported by one or more wheel bearings for rotation about the axle hub along a rotation axis. An electric drive is disposed, at least in part, within the axle housing, and a hub gear set is disposed, at least in part, within the axle hub and configured to transmit power from the electric drive to the output hub for rotation of the dual wheel arrangement. A wheel brake disposed radially between the axle hub and the output hub and axially between the ends of the output hub is configured to selectively permit and arrest rotation of the output hub.

A dual mode vehicle that operates on guided rails and roadways includes a capsule, a carriage, a front left drive system, a front right drive system, a rear left drive system, a rear right drive system, a pod control unit, and at least one battery. The carriage includes a spherical frame-housing and a base. A spherical cabin of the capsule is attitudinally mounted within the spherical frame-housing. The front left drive system, the front right drive system, the rear left drive system, and the rear right drive system each includes a motor, a drive axle, a road wheel, and a rail wheel. The road wheel and the rail wheel are axially mounted to the drive axle. The motor that is mounted to the base is operatively coupled with the drive axle through the at least one battery and the pod control unit to operate a roadway or railway transportation mode.

A modular axle and motive wheel system comprises: a pair of opposed axle ends and attached axle hubs; a pair of inner motive wheels each comprising an outer surface and configured for radially extending rotatable disposition on the hubs; and a pair of inner electric hub motors each comprising an inner stator and an inner rotor, the inner stators configured for attachment to the axle hubs, the inner rotors configured for attachment to the outer surface of the inner motive wheels, the inner rotors configured for rotation of the inner motive wheels by and about the inner stators; the inner motive wheels configured for attachment of a pair of outer motive wheels each comprising an outer electric hub motor comprising an outer stator configured for selective attachment to the inner stator and an outer rotor configured for attachment to the outer motive wheel and rotation of the outer motive wheels.
