A steering axle for steering the wheels on the axle of a four-wheel forklift truck by a hydraulic or electric steering device. The steering axle has an axle beam with first and second wheel carriers. The wheel carriers are arranged pivotably on the axle beam. A steering rod is connected, in articulated fashion, to the two wheel carriers in order to transmit steering movements. A steering actuator produces the steering movement and has an actuator housing. The actuator housing has at least one guide section for the passage of the steering rod through the actuator housing. The steering actuator has at least one sliding bearing device for the radial support of the steering rod on the at least one guide section.

An axle tube assembly includes an axle tube, a cylindrical tube reinforcement apparatus inserted into the axle tube and fixed to the axle tube, and a spindle assembly coupled to the tube reinforcement apparatus the spindle assembly having a spindle body welded to the peripheral edge of the axle tube at the end coupled to the tube reinforcement apparatus.

An apex axle truss system includes a first apex axle truss including a sheet of metal that has been bent to form a first substantially vertical wall, second substantially vertical wall, first angled wall, and second angled wall. The first substantially vertical wall is configured to be secured to a first lateral side of an axle housing. The second substantially vertical wall is configured to be secured to a second lateral side of the axle housing. The first angled wall is disposed between the first substantially vertical wall and the second substantially vertical wall. The second angled wall is disposed between the first angled wall and the second substantially vertical wall. The first angled wall and the second angled wall form an apex that is configured to be disposed over an upper surface of the axle housing.

An axle assembly having a spindle yoke defining at least one fluid conduit therethrough. A collector ring disposed about the spindle yoke. A seal housing coupled with a knuckle, and the seal housing disposed coaxially with the collector ring. First and second rotary seals disposed radially between the collector ring and the seal housing. Additionally, a port disposed in the knuckle, wherein the port is in fluid communication with the spindle yoke at least one fluid conduit via the seal housing and the collector ring.

An axle assembly having an axle housing including a differential assembly having a ring gear and a lubrication directing assembly disposed directly adjacent to the ring gear. The lubrication directing assembly having a first lubrication flow surface, a second lubrication flow surface, and a trough. The axle assembly also includes an axle housing cover surrounding the axle housing. A fluid storage tank is attached to the housing cover, wherein the fluid storage tank includes a fill channel directly attached to the rear housing cover; an expandable air bladder disposed in the fluid storage tank; and a first valve disposed below the air bladder and in contact with the air bladder.

A modular axle assembly for supporting wheels of an agricultural vehicle, such as a combine harvester. The modular axle assembly includes a first tube, a second tube parallel to the first tube, and at least one bracket connecting the first tube and the second tube.

An axle housing supporting structure includes an axle housing, a brake housing, an axle bracket for supporting the axle housing and the brake housing, a connecting member inserted in the axle housing and the axle bracket to connect the axle housing and the axle bracket for preventing the axle housing from falling from the axle bracket, and at least one co-fastening bolt fastening the axle bracket, the brake housing, and the axle housing together.

An axle assembly for a vehicle. A movable housing is movably positioned within a closed channel defined by a central housing. The movable housing moves the axle assembly between a retracted configuration and an extended configuration. A mounting assembly may be coupled to and spaced from the movable housing and slidably positioned adjacent the central housing. A steering actuator is coupled to a steering arm and the mounting assembly such that the steering actuator moves as a unit. A track assist bracket may be fixedly coupled to the central housing and define a gap sized to slidably receive a mounting plate of the mounting assembly. A bushing may be disposed on each wall of a telescoping portion of the movable housing. A bellows may be provided to enclose exposed portions of the bushings in the extended configuration. Methods of adjusting the track of the axle assembly are also disclosed.

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.

An e-axle assembly includes a housing extending from a first housing end to a second housing end to define an internal compartment. At least one electric motor is disposed in the internal compartment and includes a stator and a rotor rotatable relative to the stator about an axis. The rotor defines a hollow extending internally within the rotor, and at least one of a gearing mechanism, a shifting actuator, and/or a differential is disposed within the hollow (and thus packaged within the rotor). In a preferred arrangement, all and any of the gearing mechanisms, shifting actuators, and differential are disposed within the hollow of the rotor. This internal packaging of the drive components within the rotor reduces an overall space and weight of the e-axle assembly relative to the prior art designs to more easily and readily achieve the smaller space and weight allotments afforded by electric and/or hybrid vehicles.
