Work vehicle axle device includes a wheel drive case utilizing a centrally disposed vertically extending first coupling portion, a centrally disposed vertically extending second coupling portion spaced from the first coupling portion and an input shaft located below an upper end of either the first or second coupling portions and being configured to transmit rotational power to wheels. The first and second coupling portions are configured to pivotally mount to the wheel drive case to a vehicle body of the work vehicle in a manner that allows the wheel drive case to pivot about an axis that, when viewed from above, is at least one of parallel to a front to back direction of the vehicle body and parallel to a centrally disposed front to back axis of the vehicle body.

A bearing axle with straight shell and hollow cross section, is characterized in that the horizontal cross section of the axle housing is hollow, space of which is laid out an electric motor, a gearshift, a final drive and a differential. The advantages of the invention are as follows: the electric motor, final drive and differential integrated on the electric drive axle are fixed on the chassis to reduce the unsprung mass. The height of the motor is increased to change its adverse operation circumstances and the electric motor is not easy to be demagnetized. If the transmission is used, the gearshift on the spring is smoother than the gearshift under the spring.

The present invention relates to a method for producing a link unit, comprising the steps of provision of a carrier, reshaping of the carrier in the region of a first connecting section in such a way that an upset section is formed, the wall thickness of the carrier being increased in the region of the upset section, and provision of a node element with a joint section, and connecting of the joint section to the first connecting section by means of a rotary friction welding method. Furthermore, the invention relates to a link unit, in which a carrier which is configured in the manner of a hollow body is connected to a node element by means of a rotary friction welding method.

A non-driven axle for a vehicle or a trailer is provided. The non-driven axle includes a first arm portion, a second arm portion, and a central portion. The first arm portion is for rotatably mounting a first wheel hub. The second arm portion is for rotatably mounting a second wheel hub. The second arm portion is on an axial end of the central portion opposite the first arm portion. The central portion is between the first arm portion and the second arm portion and may be substantially U-shaped or substantially ring-shaped. The substantially U-shaped central portion includes a main portion and a radially inner portion. The substantially ring-shaped central portion includes a main portion and an inner portion. The non-driven axle reduces a weight of a vehicle or trailer while capable of being lifted without interfering with an operation of a drive axle.

A chassis link has a link body, a ball joint socket being arranged at one link end of the link body. The ball joint socket has a cylindrical portion and an outwardly directed flange which is formed from the same material as and in one piece with the cylindrical portion. The ball joint socket is joined by way of the flange to a first web of the link body. A second lower web of the link body is joined to the cylindrical portion.

An axle beam comprises a hollow middle portion and a pair of hollow end portions. The hollow middle portion has a first corner-curved tapered arch cross-sectional shape. The pair of hollow end portions each have a substantially circular cross-sectional shape, and each extend from an opposite end of the middle portion. The hollow middle portion has a first wall thickness. The hollow end portions each have a second wall thickness that is larger than the first wall thickness.

Provided discloses an integrated axle assembly and structural assembly. The integrated axle assembly comprises an axle tube assembly extending in a first direction; a front support arm extending circumferentially from the axle tube assembly in a second direction perpendicular to the first direction for attachment to the frame; a rear support arm extending circumferentially from the axle tube assembly in a third direction away from the second direction for mounting a resilient assembly; and a brake base plate extending in a peripheral direction from the circumference of the axle tube assembly; the axle tube assembly, front bracket arm, rear bracket arm and brake base plate are molded in one piece, which improves the assembly efficiency.

A vehicle suspension assembly includes providing an axle assembly having a first end including a first mounting structure and a second end, providing a first bearing block and a second bearing block, forming a first aperture in the first bearing block and a second aperture in the second bearing block, attaching the first and second bearing blocks to the first mounting structure subsequent to forming the first and second apertures; and providing a first spindle assembly coupled to the first mounting structure by a first spherical bearing located within the first aperture and a second spherical bearing located within the second aperture, wherein a first kingpin assembly extends through the first and second spherical bearings, thereby coupling the first spindle with the first mounting structure.
