  • Patent number: 8985710
    Abstract: A flanged bearing ring (10) for the wheel of a motor vehicle includes a tubular core (15) and an outer body (16) around the core. The core (15) and the outer body are made of two different materials and joined as a single piece. The outer body forms a radial flange (17) and is made of a lighter material than that of the core. At both axial ends of the ring, the radially outer surface of the core provides a succession of depressions (27) and ridges (28) which extend in a circumferential direction, and cause the formation of complementary recesses and reliefs in the outer body (16). This results in a long meander-like path that opposes or at least delays the entrance of contaminant or corrosive agents between the outer body (16) and the core (15).

A fitting portion 16 of an axle housing 14 corresponds to the shape of the pilot portion 21. An annular groove 22 is formed at the tapered portion 21b of the pilot portion 21. A seal ring 23 is mounted in the annular groove 22. An outer diameter d3 of the seal ring 23, after mounting, is set smaller than an inner diameter d4 of the cylindrical portion 16a of the axle housing 14. The seal ring elastically contacts the axle housing 14. A slight gap of a fitting portion between the outer member 20 and the axle housing 14 is blocked off.

The bearing includes a seal member configured to cover internal workings of the bearing. The wheel bearing assembly also includes an annular slinger arranged on the wheel hub and configured to at least partially screen the seal member to minimize ingestion of contaminants by the bearing from the ambient. The wheel bearing assembly additionally includes an annular shield configured to at least partially shield the slinger from the contaminants and generate a labyrinth path from the ambient to the seal member for any of the contaminants. A vehicle employing the above described wheel bearing assembly is also disclosed.

    Abstract: A hub unit includes a rolling bearing and a flange integrally formed with a hub wheel that may function as a bearing ring member of the rolling bearing. The flange has a plurality of thick portions formed at predetermined intervals in the circumferential direction of the flange. Each thick portion has a bolt hole that extends through the corresponding thick portion in the thickness direction of the thick portion. Work holes through which a working tool is able to be inserted and which extend through the flange in the thickness direction of the flange are formed between the bolt holes adjacent to each other in the circumferential direction. A circumferential width of each thick portion that has the bolt hole and that is adjacent to the work holes in the circumferential direction is set to such a width dimension that the thick portion does not interfere, with the adjacent work holes.

    Abstract: A flanged bearing ring for a motor vehicle wheel includes two different materials joined as a single piece: a tubular core and an outer body around the core. The outer body forms a radial flange and is made of a lighter material than that of the core. The ring further includes an element of generally tubular shape, which contacts both the outer body and the inner core to cover and seal with continuity a circular line of separation at the end of the interface surface between the core and the outer body at the axially outer side of the ring. The tubular element further forms a cylindrical axial edge which extends in an axially inner direction and is fixed in the axially outer end of the core cavity, and a cylindrical tubular portion, projecting in an axially outer direction beyond the flange, for centering the vehicle wheel.

  • Patent number: 8186767
    Abstract: The two-piece wheel rim assembly includes first and second hub sections affixed together and rotatably mounted on an axle by a set of bearings which are longitudinally spaced apart on the axle. The hub sections have radially inboard wall segments and radially outboard segments. The inboard segments form a radial cavity about the axle longitudinally bounded by the bearings. An oil bath substantially fills the radial cavity except for a small thermal expansion air pocket. The thermal expansion air pocket is positioned above the axle and the bearings when the hub-tire combination is in use. The thermal expansion air pocket has a nominal size only sufficient to account for thermal expansion and contraction of the wheel.
