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.

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.
