An extendable axle with wheels on a common centerline preferably includes a base housing, a left axle device, a right axle device, a left extension cylinder and a right extension cylinder. The left axle device slides into a left side of the base housing and the right axle device slides into a right side of the base housing. The left axle device preferably includes a base tube, a steering knuckle, a drive motor and a steering cylinder. The steering knuckle is pivotally engaged with an end of the base tube. The drive motor is retained on the steering knuckle. The steering cylinder pivots the steering knuckle. The right axle device is the left axle device rotated 180 degrees. The left extension cylinder extends the left axle device. The right extension cylinder extends the right axle device. The left drive motor and the right drive motor are on the same centerline.

An adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions. The assembly includes a mounting plate mountable to the suspension of an off road vehicle, and a portal box is mountable to the mounting plate. The portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft. The portal box is mountable to the mounting plate in a first position in which the output shaft is positioned to extend the wheelbase relative to the input shaft, or in a second position in which the output shaft is positioned in vertical alignment with the input shaft.

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.

Disclosed are an electric wheel assembly applicable for a parallelly mounted dual-tire wheel, an axle, and a vehicle. The electric wheel assembly includes a wheel and support axle assembly, an internal-rotor hub motor, a planetary gear reducer and a brake system. A planetary carrier is connected to a hub. The hub is connected to a spoke and a rim. The wheel support axle passes through a rotor sleeve and is provided with a hub bearing to support the hub and a whole wheel. A sun gear disposed at an end of the rotor sleeve of the internal-rotor hub motor is a power input of the planetary gear speed reducer, and the planetary carrier is a power output. A planetary gear of the planetary gear reducer is a tower-shaped gear and realizes a relatively high transmission ratio under a condition that an axial length is relatively small.

An axle assembly and method of manufacture. The axle assembly may include a sleeve that is disposed in a spindle and that is in sealing engagement with the spindle proximate opposing ends. The sleeve has a smaller diameter than the spindle such that a fluid passage is provided between the spindle and the sleeve.

A solid electric axle is suitable for use on a heavy duty work vehicle. One or two motors are concentric with the half-shafts. The main housing includes a center support and two other pieces which are bolted to the center support. A linear actuator is used to lock the differential and also to select a neutral mode in which the rotors of the motors can be stationary while the vehicle moves.

An axle assembly having at least one lubricant passage. A differential carrier, a motor housing, and a cover may cooperate to at least partially define a first lubricant passage that routes lubricant from an axle housing to the cover. The differential carrier, motor housing, and cover may cooperate to at least partially define a second lubricant passage that routes lubricant from the cover to the axle housing.

An axle housing assembly includes an axle housing that includes a center portion and a first arm portion that extends from the center portion. The axle housing assembly further includes a wheel end housing that includes a wheel end body that extends from the first arm portion and a spindle that extends from the wheel end body.

A work vehicle includes an axle frame extending in a left-right direction, a cylinder coupled to the axle frame, and a first supply conduit connected to the cylinder and configured to supply hydraulic fluid to the cylinder. The first supply conduit is fixed to the axle frame.

An axle tube assembly includes an axle tube, a first tube reinforcement apparatus disposed in the axle tube at one end and a second identical tube reinforcement apparatus disposed into the axle tube at the second end the reinforcement apparatuses welded in place to the axle tube, a first spindle assembly coupled to the first tube reinforcement apparatus, a second spindle assembly coupled to the second tube reinforcement apparatus, and an elongated connector rod or tube connected to the first and second to reinforcement apparatuses inside the axle tube and disposed between the reinforcement apparatuses the first and second spindle assemblies having spindle bodies welded to the cylindrical ends of the axle tube.
