ABSTRACT:
Several embodiments of a wheel assembly for use with large, off-highway vehicles, comprising a drive motor mounted on the wheel hub, and brake calipers cooperating with an annular brake disc supported by a disc carrier which is "outboard" or disposed radially outwardly of the brake calipers, for providing greater heat dissipation and greater braking forces upon the application of braking pressure. In one embodiment, the brake disc is secured to the carrier at its outer periphery by a plurality of circumferentially spaced bolts. In two other embodiments, the brake disc is mounted for limited relative movement with respect to the carrier to accommodate radial and circumferential thermal expansion and contraction in aggravated situations. In one of these other embodiments, the brake disc is retained against excessive circumferential movement relative to the carrier by a plurality of individual lugs affixed to the carrier. In the last embodiment, such movement is prevented by lugs formed integrally with a ring element secured to the carrier.
