An axle suspension system and a method of manufacture. The axle suspension system may have an axle, an axle wrap, and a weld seam. The axle wrap may have first and second wrap portions that mechanically interlock with each other and that have overlapping ends that may receive a weld seam.

A vehicle axle body is provided for incorporation into a vehicle axle. The vehicle axle body may be comprised of first and second axle body pieces. The first axle body piece may define at least a portion of a lower surface of the vehicle axle body and at least a portion of one of a front surface and a rear surface of the vehicle axle body. The second axle body piece is secured to the first axle body piece and may define at least a portion of an upper surface of the vehicle axle body and at least a portion of the other one of the front surface and the rear surface of the vehicle axle body. The thickness of the first and second axle body pieces may be different. Suspension component supports may be integrally formed with the upper and/or bottom surfaces of the axle body.

This disclosure details electrified vehicle drive systems equipped with electric machine integrated axle assemblies. An exemplary electrified vehicle drive system includes a leaf spring assembly and an axle assembly mounted to the leaf spring assembly. The axle assembly may include a cradle and an electric machine mounted within the cradle. Shocks and stabilizer bar assemblies may extend between the cradle and a vehicle frame of the electrified vehicle.

The invention relates to an axle unit comprising an axle tube and a link element, wherein the axle tube substantially extends along a tube axis, wherein the link element has a joining portion with a first welding portion and a second welding portion, wherein the link element is arranged with its joining portion adjacent to the axle tube and substantially transversely with respect to the tube axis, wherein, in the first welding portion and in the second welding portion, a welded joint can be produced between the link element and the axle tube.

The present invention concerns an axle unit comprising a stub axle and an axle tube, wherein the stub axle has a longitudinal channel which extends inside the stub axle substantially along a stub axis, wherein the stub axle has a transverse channel which extends inside the stub axle substantially transversely to the stub axis and opens to the environment at the outer face of the stub axle, wherein the longitudinal channel and the transverse channel are connected together, wherein the stub axle has a stub joining region to which the hollow-bodied axle tube can be secured.

An axle unit includes an axle tube and a suspension arm element, wherein the axle tube extends substantially along a tube axis, wherein the suspension arm element has a first joining region comprising a recess, wherein the first joining region of the suspension arm element is adjacent to the axle tube, wherein the suspension arm element is substantially transverse to the tube axis, and wherein a weld portion between the suspension arm element and the axle tube is located in the first joining region.

An axle unit comprising a first suspension arm element and a second suspension arm element, wherein the first suspension arm element and the second suspension arm element can be mounted on a vehicle frame so as to be pivotable about a common pivot axis, wherein the first suspension arm element has a first joining region configured as a recess, and the second suspension arm element has a second joining region configured as a recess, wherein the first joining region and the second joining region are arranged on two opposing sides of an axle tube extending substantially along a tube axis, and wherein the axle tube can be secured by substance bonding in the first and second joining regions to the first and second suspension arm elements.

A vehicle suspension includes at least one anchor bar, at least one axle lift spring, an auxiliary drop-type axle which may be selectively lifted or lowered and a single, integrated support attaching the at least one axle lift spring and the at least one anchor bar to the auxiliary drop-type axle, wherein the single, integrated support provides the only attachment of the at least one axle lift spring and the at least one anchor bar to the auxiliary drop-type axle, and wherein the support includes an open area configured to allow the passage of a cardan.

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 document provides a damper spring support and a vehicle axle having the same. The damper spring support includes: a first angle adjustment mechanism configured for being fixed to a vehicle body; a support base configured for supporting a damper spring; and a connection structure configured for detachably fixing the support base to different positions of the first angle adjustment mechanism. If the support base being fixed to different positions of the first angle adjustment mechanism, a damper spring support surface of the support base facing different directions.
