An aircraft wheel including a rim (2) comprising two assembled-together rim halves (3a, 3b), each rim half (3a, 3b) having a bearing surface (7) extending in a plane perpendicular to an axis of rotation (X) of the aircraft wheel. The aircraft wheel further includes a spacer (9) situated between the two bearing surfaces (7) when the rim halves (3a, 3b) are assembled together.

This invention relates to the lubrication of a wheel support 10. The wheel support 10 comprises support 10 comprises a housing 12 that includes a base portion 14 defining a cavity 16 for receiving therein at least one gear 40, and lubricant for lubricating the gear 40. Opposing first and second arm members 18.1, 18.2 extend respectively from the base portion 14. A free end of each arm member 18.1, 18.2 includes a bearing receiving formation 20.1, 20.2 for receiving therein a bearing. The wheel support 10 further comprises internal lubricant feed means 22, defined in the housing 12, and that extends internally from the base portion 14 into at least one of the arm members 18.1 or 18.2 for feeding lubricant operatively received from a lubricant supply, internally, via the base portion 14, to the bearing receiving formation 20.1 or 20.2 associated with the at least one arm member 18.1 or 18.2.

An axle assembly for a landfill compactor includes an axle housing, a carrier housing located proximate the center of the axle housing, a drain plug located on an underside of the carrier housing, and a guard. The guard is attached to the underside of the carrier housing with adhesive such that the guard covers the drain plug and is configured to protect and give access to the drain.

Methods and systems are provided for adjusting a lubrication system based on an axle configuration of a tandem axle with a disconnect feature. In one example, a method may include adjusting an oil level in an axle sump of a tandem axle based on an axle configuration of the tandem axle (e.g., whether the tandem axle is operating with one of a 6×4 axle configuration and a 6×2 axle configuration), the axle sump selectably coupled to an external reservoir via a first passage and a second passage, the first passage including an electric pump, the second passage including a valve, and the tandem axle coupled to a drivetrain of a motor vehicle. In this way, an amount of oil in the axle sump may be adjusted based on the tandem axle configuration.

Systems are provided for an axle arm including a lubricant reservoir and a driveshaft. In one example, system may include a lubricant reservoir of an axle arm comprising a fill line at an edge of a driveshaft, wherein a central axis of the lubricant reservoir is misaligned with a central axis of the driveshaft.

System and method for constantly monitoring the state of the oil of the wheels of heavy machinery, in particular mining trucks, while they are in motion. Comprising a server; a wireless sensor module attached to the rim of the wheel, obtaining oil measurements from an oil quality sensor, which sends the measurements to the server wirelessly; the sensor, located inside the sensor module; and a spoon-type mechanism which maintains the sensor in permanent contact with the oil inside the wheel, wherein said spoon-type mechanism rotates with the sensor module and the wheel. In addition, it may comprise a receiving antenna module which is located between the sensor module and the server. In addition, it may comprise a transmitter which is located between the receiving antenna module and the server.

An axle assembly that includes a differential carrier, a bearing cap, and a lubricant reservoir. The differential carrier has a bearing support. The bearing cap is disposed on the bearing support. The lubricant reservoir is mounted on the bearing cap and is configured to capture lubricant that is splashed by the differential assembly.

A hub-integrated inflation system which functions to convert relative motion at the wheel end (e.g., between the axle and the hub or wheel) into a pumping motion. The relative motion is then converted into mechanical or electrical energy, which can be used to actuate a pump of an inflator.

In one aspect, an apparatus for retaining lubricant in a wheel hub assembly, the wheel hub assembly including a wheel hub and a spindle nut for securing the wheel hub to a vehicle spindle. The apparatus includes an annular lubricant seal, a mounting portion of the lubricant seal to be mounted to the wheel hub, a central opening of the lubricant seal to receive a running surface of the spindle nut, and a sealing portion of the lubricant seal extending around the central opening of the lubricant seal. The sealing portion is configured to form a dynamic seal with the running surface of the spindle nut and keep the lubricant from escaping between the sealing portion of the lubricant seal and the running surface of the spindle nut as the wheel hub rotates around the vehicle spindle.

An apparatus for a vehicle is provided that has an axle and a spindle sleeve with a spindle sleeve inner surface axis coaxial with the axis of the axle, and a spindle sleeve outer surface axis not coaxial with the axis of the axle. A hub has an axis coaxial with the spindle sleeve outer surface axis, and the hub at least partially defines a chamber. First and second ports extend through a wall of the hub to the chamber. The hub rotates about the spindle sleeve through the aid of two bearings. Lubricant is present within the chamber, and the first port provides a pathway for a pressurized fluid to be introduced into the chamber to force the lubricant out of the chamber via the second port.
