Abstract: A wheel hub cover arrangement for covering an outwardly directed wheel hub opening of a wheel hub, which has a cover surface element which is connected to the wheel hub via a wall member and a connection member in such a way that the cover surface element and the wall member enclose a cover volume, wherein at least one venting opening for venting and for pressure-equalizing a vehicle shaft connected to the wheel hub is provided, wherein at least one outlet opening for removing splash water from the cover volume is provided in the wall member, wherein provisions are provided which ensure a fluid connection of the outlet opening with the surroundings of the wall member.

Abstract: A hub unit of the present invention includes a cap that covers an opening of a pilot portion, and the cap includes a cap body formed in a disc shape, and a cylindrical portion extending in an axial direction from an outer periphery of the cap body. The cap is removably attached to the pilot portion by screwing an external thread portion formed on an outer periphery of the cylindrical portion of the cap, to an internal thread portion formed on an inner periphery of the pilot portion.

Abstract: A wheel cover for a skate board is securable to a tubular bearing sleeve inserted in the central aperture of a skate board tire.

Abstract: A dust cap is mounting on the front wheel of a racing car to prevent contamination of the corresponding wheel bearings. The dust cap is threaded for engagement with corresponding threads formed on the wheel hub to allow the dust cap to be quickly removed or installed. An O-ring housed in a groove formed in the wheel hub engages the outer circumference of the dust cap to affect a seal between the dust cap and the wheel, and to restrict rotational movement of the dust cap and prevent an unintentional disengagement of the dust cap from the wheel. The closed end of the dust cap is formed with hexagonal flats having a spacing that fit the wrench used for engagement of the nut holding the wheel on the axle spindle, thus reducing the time needed for removal of the front wheel, particularly during pit stops in a car race.

Abstract: An axle extension assembly for extending an axle having a longitudinal axle bore. The axle extension assembly includes a shaft having an axle bore insert portion that is adapted for insertion in the longitudinal axle bore. The axle bore insert portion includes a bore engaging element cooperative between the axle bore insert portion and the longitudinal axle bore for securing axle bore insert portion within the longitudinal axle bore. The shaft also includes an extension portion connected to and extending from the axle bore insert portion of the shaft. The extension portion includes an accessory engaging element.

Abstract: A bicycle hub cover assembly is installed on a bicycle hub to provide a hard, rigid protective cover for the bicycle hub. In one embodiment, the bicycle hub cover assembly has a hub shell cover, a first hub end cover, a second hub end cover and a pair of fasteners that attach the hub end covers to the axle of the bicycle hub. The hub shell cover is configured and arranged to be mounted concentrically around a center portion of the hub shell of the bicycle hub, while the hub end covers overlie the axial ends of the bicycle hub. Thus, the bicycle hub is completely enclosed, except for a small gap located between the hub shell cover and each of the first and second hub end covers. In another embodiment, the hub shell cover is eliminated.

Abstract: The go kart wheel assembly comprises a hub assembly, including a hub, a tire mounted on the hub and a hub cover. The hub includes an outboard peripheral flange and a single hole for receiving a first fastening fastener and at least one projection for cooperating with corresponding projections on the hub cover. The hub cover has at least one projection for cooperative engagement in abating relation internally with each of the at least one projections on the hub. The hub cover is adapted to be visually distinguished from a sidewall of a tire adjacent to the hub cover. Finally, the hub cover is positioned thereby to prevent entering of water into the hub assembly of the go kart wheel assembly at least approximately in a plane which includes the outboard peripheral flange on the hub and is securely held.
