An axle assembly having a bearing support, a roller bearing assembly, an adjuster ring, and a locking fastener. The adjuster ring and the roller bearing assembly may be disposed on and may receive a bearing journal of the bearing support. The locking fastener may inhibit rotation of the adjuster ring.

A final transmission for agricultural and industrial motor vehicles. The transmission includes a differential unit having a support structure and a differential that transmits an input motion to an intermediate transmission shaft and a transfer unit with a final shaft that transmits the motion to the driving wheel. The final transmission also has a toothed output wheel integral to the intermediate transmission shaft which engages respectively with an internally toothed crown wheel and with an intermediate toothed wheel, and also at least one toothed support wheel which engages with the internally toothed crown wheel and with the intermediate toothed wheel.

Provided herein is an electric tandem axle having a first drive axle assembly having a first differential assembly drivingly engaged with a first drive axle; a second axle drive assembly having a second drive axle drivingly engaged with a second differential assembly having a first axle output shaft and a second axle output shaft and an axle disconnect clutch; an inter-axle assembly is drivingly connected to the first axle drive assembly and the second axle drive assembly; a motor-generator in driving engagement with the first and second drive axle assemblies; a planetary drive unit including a selection clutch in driving engagement with the first differential assembly, the inter-axle assembly and the motor-generator; and a controller connected to the motor-generator, selection clutch and axle disconnect clutch. The controller is configured to selectively engage and disengage the selection clutch and axle disconnect clutch to facilitate different modes of operation.

An axle assembly with a housing, a shaft received in the housing, a shaft bearing supporting the shaft for rotation relative to the housing about a shaft axis, a differential assembly, an annular band and a secondary retainer. The shaft bearing has an inner race, which is received on and directly engaged to the shaft, and an outer race that is received on and directly engaged to the axle housing. The differential assembly has an output member that is non-rotatably coupled to the shaft. The annular band is fixedly coupled to the shaft at a location along the axle shaft axis between the inner race and the output member. The secondary retainer is disposed along the axle shaft axis between the annular band and the output member and is configured to limit movement of the annular band along the axle shaft axis in a direction toward the output member.

An axle carrier housing for a beam axle assembly having at least one continuous transversely extending support rib with a portion of the support rib swept longitudinally rearward of a pair of axle tubes. The support rib has end portions initiating adjacent where the axle tubes connect to the housing and a central portion extending offset from the axle tubes. The central portion of the support rib provides a portion of an access cover attachment surface. The housing may define a pair of support ribs substantially mirroring each other on lower and upper portions of the housing. The support ribs provide for a structural member substantial enough to handle the loads of the axle assembly while also minimizing both the weight of the housing and fluid volume.

A method for forming an axle shaft that includes friction welding a tubular shaft to a shaft portion of a wheel flange. Portions of the joint members on the tubular shaft and the wheel flange are extruded into an annular weld cavity in the wheel flange during the formation of the friction weld. A related axle shaft is also provided.

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.

An axle assembly having a wheel mount that is disposed on a planet carrier of a planetary gear set. The wheel mount may be fixedly positioned with respect to the planet carrier with one or more fasteners and one or more dowels so that the wheel mount and planet carrier may rotate together about an axis.

A hub arrangement for twin wheels comprises a stationary carrier; an intermediate hub which is rotatable about an axis of rotation and which can be driven by a drive shaft; a differential gear having an input which is connected to the intermediate hub; a first wheel hub which is connected to a first output of the differential gear; and a second wheel hub which is connected to a second output of the differential gear. The hub arrangement furthermore comprises a first braking apparatus which is effective between the stationary carrier and the intermediate hub and a second braking apparatus which is effective between the stationary carrier and the second wheel hub or between the intermediate hub and the second wheel hub. In this respect, the first braking apparatus and the second braking apparatus can be actuated separately from one another.

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).
