A hub-integrated inflation system which functions to convert relative motion at the wheel end (e.g., between the axle and the hub or wheel) into a pumping motion. The relative motion is then converted into mechanical or electrical energy, which can be used to actuate a pump of an inflator.

A first labyrinth seal includes: a drive shaft side annular protrusion that is formed on one of the slinger and the drive shaft seal plate and that protrudes over the circumference of the drive shaft; and a drive shaft side annular groove that is formed on the other of the slinger and the drive shaft seal plate and that recedes over the circumference of the shaft. A second labyrinth seal includes: a carrier-side annular protrusion that is formed on one of the carrier seal plate and the planetary carrier and that protrudes over the circumference of the shaft of the planetary carrier; and a carrier-side annular groove that is formed on the other of the carrier seal plate and the planetary carrier and that recedes over the circumference of the shaft.

A plug for a hubcap includes a base configured to fit into and obstruct a port of a hubcap. The base at least partially defines a cavity therein. The plug also includes a cap extending radially outward from the base. The cap defines an opening therein, the opening extending at least partially radially, and a passage extending axially between the opening and the cavity. The opening is in fluid communication with the cavity via the passage.

An apparatus for a vehicle is provided that has an axle and a spindle sleeve with a spindle sleeve inner surface axis coaxial with the axis of the axle, and a spindle sleeve outer surface axis not coaxial with the axis of the axle. A hub has an axis coaxial with the spindle sleeve outer surface axis, and the hub at least partially defines a chamber. First and second ports extend through a wall of the hub to the chamber. The hub rotates about the spindle sleeve through the aid of two bearings. Lubricant is present within the chamber, and the first port provides a pathway for a pressurized fluid to be introduced into the chamber to force the lubricant out of the chamber via the second port.

A vehicle axle includes, an axle gear unit housing and axle tubes adjoining the latter. The axle gear unit housing has an opening which is surrounded by a flange. Threaded blind bore holes extend beyond the thickness of the flange into the region of the wall of the axle gear unit housing which has radially outwardly on the side of the flange facing the axle gear unit housing a wall thickening which extends annularly radially circumferentially along the flange and which is configured in a continuously annular manner or so as to form spot faces partially in the areas of the threaded blind bore holes, wherein a joint flash extends in a central plane along the axle tubes and toward the flange 4 in the region of the axle gear unit housing and at the flange along the radially outer contour of the wall thickening.

An axle assembly includes at least one axle. An axle housing having a center portion and at least one arm portion that extends from the center portion is provided: The at least one arm portion receives the at least one axle. A conduit assembly directs lubricant from the center portion to the at least one arm portion. The conduit assembly includes one or more restrictions that impede a flow of the lubricant in the conduit assembly.

A vehicle including at least one wheel and at least one hub assembly associated with the at least one wheel. The at least one hub assembly includes a hubcap. The hubcap has a transparent body configured for housing a lubricant, a fill port, and at least one continuous indication feature such that a lubricant volume is indicated in any orientation of the hubcap.

The present disclosure relates to a wheel connecting structure and a baby carrier. The wheel connecting structure includes a fixed base, a rotatable base, a rotating shaft and an anti-swing member. The rotatable base is rotatably connected to the fixed base by the rotating shaft. The anti-swing member has an abutting portion. The anti-swing member is arranged on one of the fixed base and the rotatable base, and the abutting portion abuts against the other of the fixed base and the rotatable base. The abutting portion is provided with a lubricating structure.

An axle depends from a heavy-duty vehicle. Each one of a pair of wheel end assemblies is mounted on a respective one of the ends of the axle. Each wheel end assembly includes a pair of bearings mounted on a spindle of the axle, and a wheel hub rotatably mounted on the bearings. A cavity is formed in the wheel end assembly between the bearings. A port is formed in the wheel hub and extends axially inwardly from an outboard end to a lubricant cavity of the hub, and angles radially inwardly from the outboard end to the lubricant cavity at an angle relative to an axial centerline of the hub. Lubricant for the bearings is introduced into the cavity by means of the port, and the port is tapped to receive a plug to seal it and contain the lubricant in the cavity. The port also provides a visual indicator if there is a leakage of semi-fluid grease.

A wheel support device for a vehicle includes a bearing that rotatably supports a wheel, and is lubricated by a lubricant, a bearing support member, and a self-discharge type charge eliminator provided on a surface of a particular member. The self-discharge type charge eliminator is configured to change air around the self-discharge type charge eliminator into negative air ions, and eliminate charge by causing the air ions to attract positive charges of the particular member for neutralization, so as to reduce the quantity of charge of the particular member, and thereby reduce the quantity of charge of the lubricant.
