A vehicle including at least one wheel and at least one hub assembly associated with the at least one wheel. The at least one hub assembly includes a hubcap. The hubcap has a transparent body configured for housing a lubricant, a fill port, and at least one continuous indication feature such that a lubricant volume is indicated in any orientation of the hubcap.

A wheel for vehicles, in particular with electric or hybrid propulsor, is provided that is apt to recover at least a part of the energy which is required in order to deform the tire of the wheel during its rotation and to transfer the energy, recovered in this manner, from the wheel to the vehicle on which the wheel is mounted, so that this energy, recovered, is used to generate the electrical energy intended to feed the devices installed on the vehicle, such as in particular the respective electric propulsor.

A wheel of a motor vehicle includes a hub portion, spokes extending radially outwards from the hub portion, a rim which is supported on the spokes, and a spoke area cover which is delimited by the rim. A respective cover is provided on both sides of the spokes, i.e. facing the interior side of the spokes and facing the exterior side of the spokes. The interior-side cover, which is annular when seen in a projection in the direction of the wheel rotational axis, is adhered to the edge of the hub portion and to an annular region of the rim and/or the interior side of the spokes. The exterior-side cover is designed in an annular manner either over its entire surface or when seen in a projection in the direction of the wheel rotational axis and can be interchangeably inserted into a groove in an annular rim region and/or in an annular region of the rim and the hub portion with an intermediately positioned seal element.

A wheel assembly is provided that includes a structure defining a wheel portion configured to receive a portion of a tire. The wheel assembly further includes a structure of the wheel portion defining an air channel from a face of the wheel portion to an area that receives the portion of the tire, an end of the air channel proximate to the face being configured to receive a valve, where the structure is further configured to receive a corrosion mitigation device within the air channel.

A central tire inflation system for maintaining tire inflation on a vehicle is provided. The central tire inflation system includes a rotary union assembly having a housing that is coupled to and rotates with the hubcap. The housing is rotationally coupled to a stationary shaft. A flexible torque transfer shaft is connected to the stationary shaft on one end and to an axle plug on the other end. The axle plug has a hub forming a bore where the hub is movable on a web of material. The flexible torque transfer shaft and hub have cooperative non-circular shapes to resist rotation. An air vent is provided in the rotary union assembly that is isolated from the lubrication area, which inhibits the pressurized air from the central tire inflation system from pressurizing the lubrication area.

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.
