A cover assembly for removably covering a hub of a wheel rim includes a ring-shaped outer cover defining a cover central hole, and a connector having a connector outer annular wall, a connector inner annular wall extending through the cover central hole for connection with a hub inner peripheral wall of the hub and provided with a first external thread for threadedly connecting with a first internal thread of the hub, and an annular flange extending from a junction of the connector inner and outer annular walls. A first elastic ring is sleeved on the connector inner annular wall and is configured to be disposed between and abut against the connector inner annular wall and the hub inner peripheral wall.

A vent plug for a hub cap is provided. The vent plug includes a cover and base forming a chamber. A vent plug body extends from the base and forms a cavity. A shield is coupled to the vent plug body. The shield comprises an annularly extending disc that traverses the cavity. The shield includes a connecting surface to connect the shield to the vent plug body. The shield provides a lubrication/liquid barrier to inhibit lubrication (or other liquid) from entering the cavity formed by the vent plug body and the chamber. The connection between the shield and the vent plug body allows a gas (typically air) to vent past the shield into the cavity and, when pressure is sufficiently high, to the chamber and eventually atmosphere.

A wheel guard includes a cover having a cone shape with an outer surface, an inner surface, a top end, a bottom rim, a first terminal edge running from the top end to the bottom rim, and a second terminal edge opposite the first terminal edge and running from the top end to the bottom rim. A coupler is configured to releasably couple the first terminal edge to a plurality of different radial points of the cover, thereby adjusting a diameter of the bottom rim.

A magnetic hub plug apparatus for sealing a wheel hub and detecting wheel bearing failure includes a plug body having a plug outer side, a plug inner side, and a plug edge. A seal ring has a proximal perimeter coupled to the plug inner side, a distal perimeter, and a seal sidewall extending from the proximal perimeter to the distal perimeter. The seal ring is configured to sealingly fit within a wheel hub cap. A magnet extension is coupled to the seal ring. The magnet extension extends from the seal sidewall and dips within an oil reservoir of the wheel hub cap with each rotation. A magnet insert is coupled within the magnet extension to collect particles from a faulty wheel bearing. A plug grip is coupled to the plug body and extends from the plug outer side.

The vehicle wheel cover retention system comprises a wheel including a first hub hole provided therein which has a retention member formed in a generally axially extending portion thereof. The wheel cover includes a second hub hole provided therein. The second hub hole includes an annular axially extending segmented projection. The segmented projection includes a chamfered outer circumferential surface and a shoulder provided thereon. During assembly, the segmented projection deflects radially inward as the wheel cover is initially installed and moved toward the retention member and then as the wheel cover is further advanced the segmented projection moves radially outward to enable the shoulder to engage the retention member to thereby secure the wheel cover to the wheel. The center cap includes an annular axially extending projection. The center cap is then installed and its annular extending projection engages with the inside of the segmented projection of the wheel cover, thus preventing it to further deflect radially inward and thereby locking the wheel cover to the wheel.

An aircraft wheel hub protector is adapted to engage an aircraft wheel including an aircraft tire on a rim. The aircraft wheel hub protector having two or more cover sections with a protective protrusion and coupling mechanism guide extending from the a first cover section and passing through a bearing race and internal surface within a hub of the rim of the aircraft wheel in such a fashion so as to provide a void within the protective protrusion. The second cover section is engaged with an opposed side of the aircraft wheel from the first cover section. A coupling mechanism passes through the void in the protective protrusion without having contact with the bearing race and internal surfaces within the hub of the rim and coupling the first cover section and securing the aircraft wheel hub protector to the aircraft wheel.
