An axle assembly having a countershaft. The countershaft may be disposed in an axle housing. An axle shaft may be disposed in the countershaft. A first clutch may control rotation of the countershaft with respect to the axle shaft. A second clutch may control rotation of the countershaft with respect to the axle housing.

Systems are provided for an axle housing for a vehicle. In one example, system includes a differential housing comprising a modular Salisbury style center section comprising tube mounts configured to receive tube assemblies via a press fit.

In some implementations, a screen assembly may include at least one plate member having at least one opening; a screen, that is fluid permeable, disposed on the at least one plate member to expose the screen via the at least one opening; an aperture through the at least one plate member and the screen to receive an axle shaft; a notch extending inwardly from an outer edge of the screen assembly to provide a passage for a fluid conduit; and at least one magnet disposed on the at least one plate member.

Brake mechanisms (33) that apply braking to rotations of left and right rotational shafts (25) each include a projecting part (40) that faces a partition wall (15A) of a brake case (15) and projects radially inward from an inner diameter side of a piston (37), an engaging member (41) that is arranged in the inner diameter side of the piston (37) in a state of being movably engaged with the projecting part (40) by a predetermined dimension in the left-right direction, and a pin member (42) that is provided between the partition wall (15A) of the brake case (15) and the engaging member (41). A frictional resistance between the pin member (42) and the partition wall (15A) is set to a value smaller than a pressing force of the piston (37) at the braking. The projecting part (40) is provided with an engaging member insertion groove (40A) that the pin member (42) penetrates in the left-right direction, and the engaging member (41) is movably engaged with the projecting part (40) in the left-right direction.

An axle assembly having an axle housing, an axle shaft, a plurality of axle shaft bearings and a seal. The axle housing has a tubular member and an end flange that is coupled to the tubular member. The axle shaft bearings and the seal are received in the end flange and are engaged to the axle shaft. The axle shaft bearings support the axle shaft for rotation relative to the axle housing. The seal is sealingly engaged to the end flange and the axle shaft. A method for assembling an axle assembly is also provided.

An assembly of a first component designed as an axle or a shaft on a second component, is provided, in particular for a vehicle. The first component is secured to the second component at least in the axial direction of the first component. At least one of the components has at least one first deformation on one side, the deformation being used to secure the first component on the second component in a first direction which coincides with the axial direction. At least one of the components has at least one second deformation on the same side, the second deformation being used to secure the first component on the second component in a second direction which coincides with the axial direction and is opposite the first direction.

A track work vehicle includes an axle input shaft defining a first axis of rotation, and a differential gear case having at least one planetary gear set. The track work vehicle includes a track drive system contained, at least in part, in the differential gear case. The track drive system includes a first gear coupled to the axle input shaft and a second gear coupled to the first gear. The track drive system includes a bevel gear assembly coupled to the second gear and a bevel gear set coupled to the planetary gear set. The track work vehicle includes at least one drive axle coupled to the planetary gear set and a drive wheel for driving a continuous ground-engaging track. The drive axle has a second axis of rotation that is vertically offset from the first axis of rotation and substantially coaxial with a centerline of the drive wheel.

A multi-speed hub drive wheel is provided which includes a wheel equipped with a hub; a star compound gear train having first and second stages; a motor disposed in the hub which drives the wheel by way of the star compound gear train; and a clutch which switches the hub drive wheel between a first mode of operation in which the motor engages the first stage of the star compound gear train, and a second mode of operation in which the motor engages the second stage of the star compound gear train.

The twist axle assembly includes a pair of spaced apart trailing arms and a twist beam of which extends in a first direction between the trailing arms. The twist beam includes a pair of end portions and a middle portion. The twist beam further has a pair of side walls and at least one additional wall that extends between the side walls. The side walls in the middle portion are generally parallel with the side walls of the end portions. The twist beam is generally hour-glass shaped with the middle portion having a first width and the end portions have a greater second width. The twist beam also tapers from the first width of the middle portion to the second widths of the end portions for gradually increasing a torsional stiffness from the middle portion to the end portions.

A wheel carrier assembly (10) of a machine for agricultural use, such as a tractor, has a drive axle (2) and steering wheels. The wheel carrier assembly (10) includes a constant-velocity joint (100) for the connection, upstream, of the wheel carrier assembly (10) to the transmission. The assembly includes, downstream, a rotation shaft (101) for the rotation of the wheel assembly. A disc brake device (200) controls the braking of the wheel assembly. A gear reducer (300), connects to the wheel assembly and to the rotation shaft (101). The disc brake device (200) is operationally connected to the rotation shaft (101) so that the braking action is applied directly on the rotation shaft, upstream of the gear reducer (300).
