An adjustable front axle includes an axle housing; an axle tube connected to an end of the axle housing; an inner-C-forging disposed on the axle tube at an end away from the axle housing; and a mounting apparatus configured for detachably fixing the inner-C-forging to the axle tube. The inner-C-forging is provided with a first angle adjustment structure, the axle tube is provided with a second angle adjustment structure. The mounting apparatus is disposed on the axle tube, and capable of cooperating with the inner-C-forging to fix the inner-C-forging to the axle tube. The first angle adjustment structure and the second angle adjustment structure have different cooperation positions such that the inner-C-forging has different installation angles relative to the axle tube. A vehicle is also provided.

An axle assembly for frame rail vehicles is described herein. The axle assembly includes a first axle shaft and a second axle shaft orientated along a first axis of rotation. A first electric machine is orientated along a second axis of rotation and a second electric machine is spaced from the first electric machine and orientated along a third axis of rotation. A differential gear set is disposed about the first axis of rotation and is coupled to and driven by a common gear reduction to transfer rotational torque from the first and second electric machines to the first and second axle shafts. A speed change mechanism is coupled between the common gear reduction and the differential gear set to change the rotational torque transferred to the first and second axle shafts.

The invention relates to an electrically drivable steering axle (10) having an axle housing (11), an electric motor (12), a transmission (13), a differential (14) with a first output shaft (18) and a second output shaft (18′), a first wheel head (15), a second wheel head (16) and a steering linkage (17, 17′, 17″). The electric motor (12) is drive-connected to the first wheel head (15) and to the second wheel head (16) via the transmission (13) and the differential (14). The steering axle (10) according to the invention is distinguished by the fact that the electric motor (12), the transmission (13), and the differential (14) are arranged coaxially with the first output shaft (18) and the second output shaft (18′). The invention additionally relates to a corresponding vehicle.

A half-shaft assembly includes a first constant velocity (CV) joint, a second CV joint and an axial movement joint connected between the first CV joint and the second CV joint. The axial movement joint includes a first shaft coupled to the first CV joint and a second shaft coupled to the second CV joint, wherein mechanical input received on the first shaft is communicated to the second shaft, and wherein the second shaft slides axially within the first shaft. The axial movement joint further includes an axial boot cover coupled on a first end to the first shaft and on a second end to the second shaft that accommodates axial movement of the first shaft relative to the second shaft. The first constant velocity (CV) joint is coupled to provide torsional input received at an input to the first shaft, the first CV joint having a first CV boot cover. The second CV joint coupled to provide torsional output received from the second shaft to an output, the second CV joint having a second CV boot cover.

A vehicle axle assembly including an axle housing, carrier assembly, and first and second axle shafts. The axle housing is formed from an upper beam and a lower beam that are positioned in a clam-shell arrangement. The carrier assembly includes a carrier housing and a differential that includes a ring gear arranged in meshing engagement with a pinion. The first and second axle shafts extend outwardly from the differential in opposite directions. The pinion is rotatably supported by a self-lubricating cartridge pinion input bearing and the outboard ends of the first and second axle shafts are rotatably supported by self-lubricating and unitized grease wheel end bearings. These bearings do not require lubrication from oil contained inside the axle housing allowing for a reduced oil fill level in the axle housing, creating less viscous losses and better efficiency.
