A front axle assembly with an axle housing that has first and second housing halves that each include a main housing portion, a tubular portion and a steering yoke. The main housing portion defines a cavity that houses at least a portion of a speed differentiation mechanism. The tubular portions are fixedly coupled to an associated one of the main housing portions and extend between the main housing portion and an associated one of the steering yokes. Each steering yoke is fixedly coupled to an associated tubular portion. An annular joint structure is formed where the first and second first housing halves are coupled to one another. The annular joint structure is formed about the rotary axis such that one of the first and second housing halves is inserted into the other one of the first and second housing halves along an insertion axis that is coincident with the rotary axis.

Systems are provided for an axle arm including a lubricant reservoir and a driveshaft. In one example, system may include a lubricant reservoir of an axle arm comprising a fill line at an edge of a driveshaft, wherein a central axis of the lubricant reservoir is misaligned with a central axis of the driveshaft.

A mounting system for a portal lift assembly of an off-road vehicle includes a housing having a rear wall, a front wall, and a side wall. The rear wall includes an opening to receive the end of one of the vehicle's axles, and the front wall includes an opening to allow an output shaft to extend outward from the housing. The rear wall also includes an integral mounting brackets effective to mount the box to an upper A-arm to the rear wall, and a lower A-arm to the rear wall.

A cylinder boot for an axle of an industrial vehicle includes a cylinder boot body, a rod-side fixing portion, a cylinder-side fixing portion, and a detection portion. The cylinder boot covers a cylinder rod of a steering hydraulic cylinder. The cylinder boot body has a contractable portion that is contractable in response to a stroke of the cylinder rod. The rod-side fixing portion is disposed at one end portion of the cylinder boot body and fixed to a distal end portion of the cylinder rod. The cylinder-side fixing portion is disposed at the other end portion of the cylinder boot body and fixed to a cylinder body of the steering hydraulic cylinder. The detection portion is displaced in a direction in which the cylinder rod extends or contracts, and is detected by a detection sensor disposed on the beam axle.

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.

Axle seat assemblies and methods of manufacturing thereof, are provided for attachment to an axle body (15). The axle seat assembly may be comprised of a first piece (42) and a second piece (50). The first piece (42) may have a first wall, a second wall and a first axle seat piece engagement portion providing a first engagement surface. The second piece (50) may have a third wall and a second axle seat piece engagement portion providing a second engagement surface. The first wall and the second wall of the first piece are oriented to engage a front surface of an axle body and the third wall of the second piece is oriented to engage a rear surface (30) of an axle body. The first and second engagement surfaces of the respective first and second pieces of the axle seat assembly are positioned and configured to engage one another to removably and reversibly secure with the use of a fastener the first piece to the second piece to form an axle seat assembly.

Provided herein is a driving apparatus for transporting a loaded object, which allows a drive-wheel to always be in contact with the ground even when the ground is uneven. The driving apparatus includes a loading plate (140, 240) on which a loaded object is loaded, a first support (110, 210) connected to a lower portion of one side of the loading plate (140, 240), a second support (120, 220) connected to a lower portion of the other side of the loading plate (140, 240), a hinge (130, 230) configured to connect the first support (110, 210) to the second support (120, 220) in a hinge structure, at least a pair of drive-wheels (160, 260) coupled to both sides of a lower portion of the second support (120, 220), and a driver configured to rotate and drive the drive-wheels (160, 260).

A removable spindle assembly improvement comprised of a spindle housing end unit having a threaded cavity. A corresponding threaded removable spindle is torqued into the threaded cavity. The spindle has a tapered section that includes O-rings for creating a seal along the corresponding section of the cavity to prevent corrosion which assists in the elimination of spindle seizure within the spindle housing end unit's cavity. The spindle housing end unit's housing includes at least two threaded apertures that cooperate with sealed set screws for securing the spindle in place during operation. The set screws are placed apart at an odd number of 15 degree increments. This assembly facilitates easy removal and replacement of a spindle on a spring axle.

A cylinder boot for an axle of an industrial vehicle includes a cylinder boot body, a rod-side fixing portion, a cylinder-side fixing portion, and a detection portion. The cylinder boot covers a cylinder rod of a steering hydraulic cylinder. The cylinder boot body has a contractable portion that is contractable in response to a stroke of the cylinder rod. The rod-side fixing portion is disposed at one end portion of the cylinder boot body and fixed to a distal end portion of the cylinder rod. The cylinder-side fixing portion is disposed at the other end portion of the cylinder boot body and fixed to a cylinder body of the steering hydraulic cylinder. The detection portion is displaced in a direction in which the cylinder rod extends or contracts, and is detected by a detection sensor disposed on the beam axle.
