An “L-shaped” bushing assembly having a retainer pin sleeve and axle sleeve. An “L-shaped” retainer pin is fitted to the retainer pin sleeve and provides a handle piece that projects through the walls of the bushing assembly and wheel that is maneuverable to retract and release the retainer pin and wheel from a grooved axle. The L-shaped retainer pin and bias spring are alternatively mounted in single and multi-channel slots to facilitate retainer pin mounting and/or containment of the retainer pin at a storage position. The retainer pin sleeve slots and/or a transverse open slot facilitate cooperation of a wheel removal tool with the retainer pin(s).

A wheel assembly includes a mounting plate for attachment to a rotatable axle, a plurality of elongate friction members for engaging a tire assembly, a plurality of first angular flanges extending radially outward and circumferentially in a first direction from the mounting plate, and a plurality of second angular flanges extending radially outward and circumferentially in a second direction, opposite the first direction, from the mounting plate. Each elongate friction member is disposed axially between one of the first angular flanges and one of the second angular flanges.

A wheel speed sensing system for a work vehicle having an engine, a transmission, a differential, and an axle, defining a central longitudinal axis and coupled to the differential. The wheel speed sensing system includes a sensor target disposed at the axle and a sensor configured to transmit a sensor signal, wherein the sensor is located adjacently to the sensor target. The sensor target includes a plurality of step splines each having a top surface and first and second planar sidewalls. The sidewalls of the step splines are aligned along a radius extending from the central longitudinal axis, such that the sides are undercut with respect to the top surface. An intersection of each of the sidewalls with the top surface defines an edge forming a relatively sharp transition configured to be sensed by the sensor. A chamfer at the intersection of the sidewalls and the top surface is also contemplated.

A wheel assembly comprising a wheel disk and a tread member disposed around the wheel disk. The wheel disk can have a substantially conical shape when in an unloaded state, but be flexible such that it can deform under load to optimize and/or maximize contact area between the tread member and a driving surface.

A hub bearing unit includes an inner ring having inboard and outboard axial ends and a bearing inner race on an outer surface. An outer ring disposed about the inner ring has inboard and outboard axial ends and a bearing outer race on an inner surface. One ring is coupled with a wheel and rotatable about an axis and the other ring is fixedly coupled with a frame. An annular displacement limiter extends radially from one ring and has a circumferential stop surface spaced radially from a surface of the other ring. The stop surface engages with the ring surface when the ring displaces radially relative to the other ring. A seal includes an annular sealing member coupled with one ring and is sealingly engageable with the limiter or is mounted on the limiter and sealingly engageable with one ring or a rigid seal member coupled with one ring.

An outer ring is disposed about the inner ring and has inboard and outboard axial ends and a bearing outer race on an inner surface. One ring is coupled with a wheel and is rotatable about an axis and the other ring is fixedly coupled with a vehicle. An annular displacement limiter extends radially outwardly from the inner ring and has a radial stop surface spaced axially from the inboard end of the outer ring. The stop surface engages with the outer ring end when one ring displaces axially relative to the other ring. Preferably, the limiter is integrally formed with an annular insert providing a bearing inner race, but may be separately formed and disposed about the insert or the inner ring outer surface.

A noncorrosive, water-impermeable gasket is used between a wheel rim and a hub assembly so that they do not corrode together making their separation difficult or impossible. The gasket includes a gasket flange with a gasket bolt pattern that is alignable with a hub bolt pattern of the hub assembly and a rim bolt pattern of the wheel rim.

An axle end assembly has a wheel brake arrangement and a wheel hub arrangement. The assembly is designed as a preassembled unit with a hollow shaft element on which the wheel brake arrangement and the wheel hub arrangement are disposed.
