An axle assembly having a planetary gear set and an internal brake assembly. The brake assembly may have a piston that may be disposed between a disc pack and the planetary gear set. Rotation of a sun gear of the planetary gear set may be inhibited when the piston urges the disc pack against a flange of an axle housing.

Certain embodiments of the present disclosure describe a portal hub assembly for raising the chassis of a vehicle. The portal hub assembly includes a portal box and a mounting assembly removably attachable to one side of the portal box. The mounting assembly includes a mounting body forged as a unitary body. A bracket assembly including at least one mounting bracket is selectively attachable to the mounting body to allow the mounting assembly to receive a component of the suspension system of a desired vehicle.

An axle assembly having an axle housing, a differential, and a ballast insert. The ballast insert may be disposed in the axle housing below the differential. The differential may have a ring gear. The ring gear may be received in a trench that may be provided in the ballast insert.

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.

The wheel side of a drive axle with wheel member steering having a drop center rim, preferably made of steel, is provided on the wheel hub and is combined with a disc brake, which is axially inwardly offset relative to the wheel plane and which preferably has compressed an actuation. The necessary space for the disc brake arrangement is guaranteed by the sufficiently low diameter of the wheel hub in the region of the brake disc and by a comparatively large axial space for the brake system, which is created by an axially narrow design of the wheel hub transmission and a by a new design of the steering knuckle bearing and of the pertaining axle guard.

A kingpin unit bearing steerable drive axle for a powered wheel of a vehicle may include a steering knuckle having a first side and a second side, and a unit bearing configured to support a wheel and operatively connected to the first side of the steering knuckle. An axle housing is operatively connected to the second side of the steering knuckle, and the axle housing has an upper arm and a lower arm. A first kingpin connects the upper arm of the axle housing to the steering knuckle; and a second kingpin connects the lower arm of the axle housing to the steering knuckle. The steering knuckle and the axle housing are configured to receive a powered axle shaft to drive the unit bearing.

A method for forming an end part of a tube, such as a hollow shaft for use as a vehicle axle, is described. A rolling body having a rolling surface with an inwardly-curved contour rotates around a longitudinal axis with a first rotational speed and a second rotational speed. The rolling body and the tube rotate in the same direction. The longitudinal axis of the rolling body is arranged eccentrically to a longitudinal axis of the tube by a predetermined normal distance. The rolling body and the tube are brought into contact such that the rolling surface contacts the end part of the tube at a contact surface situated on an inner tube wall. The rolling body transfers a force to the inner tube wall by a relative movement between the rolling body and the tube such that the end part of the tube is formed radially outward.

A portal box assembly for mounting a wheel to an off road vehicle in a lifted and extended wheelbase position. The assembly includes a portal gear box having an input shaft opening for an input shaft, and an output shaft extending from an output shaft opening. The portal gear box also includes a set of gears effective to transmit power from the input shaft to the output shaft, and optionally to reduce the gear ratio. The assembly is mountable to the vehicle in an extended wheelbase position in which the output shaft is positioned below and forward of the input shaft when the assembly is used to mount a forward wheel, and in which the output shaft is positioned below and rearward of the input shaft when the assembly is used to mount a rear wheel.

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.
