A constant velocity joint for a vehicle may include: a hub housing combined with the constant velocity joint in the hub housing; a bearing assembly including an inner race fitted on an outer surface of the hub housing, an outer race spaced a predetermined distance apart from the inner race and fitted on a knuckle, and a power transmission member disposed between the inner race and the outer race; and a boot having a band seat that is positioned on the inner race of the bearing assembly, the boot having a fixing band fixed on a top of the boot and the boot being coupled to the inner race by the fixing band, where the boot includes a boot lip that is formed at one end or both ends of the band seat and protrudes toward the knuckle.

A hub mounted grease cap having a sleeve with an inner end and an outer end. The outer end has an outer end surface that is opposite the inner end. The sleeve encloses a bore that extends through the sleeve. The inner end has an outer diameter that may be a press fit or threaded connection to a hub into which it is installed. An end plug has an end wall and an aperture through the end wall. There is a shaft that extends through the aperture in the end wall of the end plug. A wedge block is connected to the shaft. A seal has a portion that is located between the end wall of the end plug and the wedge block. The seal expands radially outward against the bore of the sleeve when the wedge block is drawn toward the end wall.

A sealing device for a wheel hub unit configured to form a static seal to protect the wheel hub unit from environmental contaminants. The sealing device including a metal shield that is coupled to a collar of the wheel hub unit, and has an end wall, a cylindrical lateral wall integral with, and orthogonal to, the end wall. The lateral wall has twice the thickness of the end wall in order to impart stiffness to the metal shield, and a stop edge integral with the cylindrical lateral wall on the opposite side to the end wall, for bearing axially against the collar; a sealing gasket formed by a silicone-based sealing compound being provided to allow the formation of a bead against a cylindrical lateral wall in an assembly configuration of the sealing device.

An all-terrain load transport system including a cylindrical first base member and at least three pairs of arms is provided. A handle is removably attached to an attachment member disposed on the cylindrical first base member. The cylindrical first base member defines a space for receiving at least one piece of accessory equipment. Each pair of the three pairs of arms defines a wheel support assembly at an end of each pair distal from an outer periphery of the cylindrical first base member. The three pairs of arms are detachably attached to the outer periphery of the cylindrical first base member. The wheel support assembly includes a cylindrical second base member defining a space for receiving a spherical wheel. The spherical wheel moves omnidirectionally within the defined space. Roller bearings positioned along an inner periphery of the cylindrical second base member facilitate the omnidirectional movement of the spherical wheel.

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 bearing assembly includes a fixed inner axle with at least one inner race, a rotatable outer hub disposed about the axle and having at least one outer race and rolling elements disposed between the inner and outer races. An annular seal is disposed between the axle and the hub and is located adjacent to the inner and outer races. A shield is spaced axially from the seal such that the seal is disposed between the rolling elements and the shield. The shield includes a rigid annular body having an outer radial end coupled with the outer hub, preferably by a plurality of couplers, and an inner radial end defining a central opening for receiving the axle and located adjacent to the inner axle or a component disposed upon the axle. As such, the annular body substantially obstructs an annular interior space to prevent substances from contacting the seal.

A wheel hub assembly for mounting on an upright of a vehicle has a flanged outer ring provided with a tubular mounting portion inserted over a first axial length (L1) inside a seat of the upright; and a plastic cover having a mounting portion which is also engaged inside the tubular portion, wherein the mounting portion extends outside the tubular portion over a second axial length (L2) which, together with the first axial length (L1), covers less than a mounting length (L) inside the seat.

A sealing device for wheel hubs connected to constant-velocity joints including a first sealing assembly arranged between inner and outer rings of the wheel hub, and a second sealing assembly mounted on the inner ring and straddling the wheel hub and an outer ring of the constant-velocity joint. The first sealing assembly has a signal generating element having an annular insert mounted externally on a shield facing the constant-velocity joint and extending axially projecting above part of an annular step formed, on the same side as the constant-velocity joint, on a radially outer side surface of the inner ring, in a position immediately adjacent to the sleeve portion of the first shield. The second sealing assembly includes a tubular support keyed onto the inner ring by its first end on the outside edge folded in the manner of an L and shaped to engage inside the annular insert.

A wheel hub assembly includes a mounting base and a wheel hub supported for rotation on the mounting base by a plurality of bearings disposed within an annular space between the hub and base. A sealing system is provided that seals all points of intrusion into the space such that liquid contaminants are inhibited or precluded from entering the space and reaching the bearings when the assembly is subjected to an immersion/thermal shock test in which the assembly is heated to an elevated temperature and then immersed on a cold bath of the liquid contaminant. A method of testing the sealing integrity of wheel hub assemblies is also provided
