A wheel loosening sensor (100; 400; 500; 600; 700) configured to detect loosening of a wheel of a vehicle, the wheel loss sensor comprising: a transmitter; a battery (128), wherein the transmitter and the battery are within a water tight housing (102) that is permanently sealed, and wherein at least two electrical terminals (104, 106) are exposed at an exterior of the housing, the transmitter being configured to receive electrical power from the battery and transmit a signal when the at least two electrical terminals are disconnected; an electrically conductive element (108) biased away from the at least two electrical terminals and configured to electrically connect the two electrical terminals when the bias is overcome.

The present invention relates to a wheel cover and to a wheel hub arrangement, wherein the wheel cover has a shielding section, which shields a gap formed between a hub and the wheel cover, and wherein a wheel hub arrangement is provided, in which a seal element is arranged in a gap formed between a wheel cover and the hub, which seal element is embodied as a profile seal.

A mounting assembly for mounting a wheel end sensor in a heavy-duty vehicle hubcap that includes at least one adhesive disposed between the wheel end sensor, hubcap, and/or components of the wheel end sensor mounting assembly to prevent aqueous road contaminants from entering the wheel end assembly and prevent lubricants from exiting the wheel end assembly during operation of the vehicle. According to one aspect of the wheel end sensor mounting assembly, the adhesive is delivered via one or more gaskets formed of a hydrophobic or non-wicking material. The one or more gaskets are disposed between the wheel end sensor, the hubcap, and/or components of the wheel end sensor mounting assembly. The one or more gaskets and the adhesives provide sealing interfaces between the components.

A guard for a seal of a wheeled industrial machine, the guard comprising an cylindrical, annular body having a first plate, a second plate with an upper portion and a lower portion, and a connecting portion extending between the first plate and the second plate; wherein the first plate extends in a radially inward direction from the connecting portion and includes a plurality of holes; wherein the upper portion is configured to extend into a corresponding slot of a rotating element of a wheel of the wheeled industrial machine; and wherein the lower portion is configured to extend toward an axle of the wheeled industrial machine.

A caster device for a pipe leg includes a caster unit, a mounting unit, and a braking unit. The caster unit includes a wheel seat subunit, a caster subunit that is rotatably connected to a bottom end of the wheel seat subunit, and a protection subunit that is located between the wheel seat subunit and the caster subunit. The mounting unit is mounted to the wheel seat subunit and is adapted to be mounted to the pipe leg. The braking unit extends through the protection subunit and the wheel seat subunit into the mounting unit, and is movable in an up-down direction between a braking position, in which the braking unit projects out of the protection subunit and is in contact with the caster subunit so that the caster subunit is refrained from rotating, and an initial position, in which the braking unit is spaced apart from the caster subunit.

A wheel bearing apparatus has a seal (8) with a metal core (15) and a sealing member (6). The metal core (15) is fit into an outer-side end inner circumference of the outer member (10). The sealing member (16) with a first side lip (16a) is adhered to the metal core. The first side lip (16a) is inclined radially outward to oppose a metal annulus (17) mounted on a base (18) of a wheel mounting flange (4), via an axial gap. The sealing member second side lip (16b) is formed radially inward from the first side lip (16a) and is in sliding contact with the base (18), via an axial interference. The sealing member third side lip (19a) is inclined radially outward from a base (19), covering the outer surface of the metal core (15), toward the wheel mounting flange (4). The tip end of the third side lip (19a) is formed with a vertically flat surface opposing the inner-side surface (4b) of the wheel mounting flange (4, 28), via an axial gap (S1), to form a first labyrinth seal (20). The outer edge of the metal annulus (17) opposes a sealing member (16), via an axial gap, to form a second labyrinth seal (25).

A wheel bearing apparatus has an outer member, an inner member, and double row rolling elements contained between the outer raceway surfaces and inner raceway surfaces of the outer member and the inner member. A cup-shaped steel protective cover is mounted on the inner-side end of the outer member. The cover fitting portion has a cylindrical portion, a radially reduced portion and an elastic member. The elastic member has an annular projection and a contact lip. When the protective cover is fit into the outer member, the annular projection closely contacts with the fitting surface while elastically deforming and the contact lip elastically contacts the inner-side end of the outer member.

A wheel hub arrangement for a motor vehicle, provided with a hub which is rotatably mounted by a wheel bearing for the attachment of a wheel. A shaft, which is formed separately from the wheel hub, is non-rotatably coupled to the wheel hub. At the same time a first receiving section of a sealing receptacle is formed in the wheel hub in which is arranged a shaft, in which a sealing device is arranged which engages a second receiving section of the sealing receptacle formed in the axial direction with respect to an axis of rotation of the wheel hub, adjacent to the first receiving section.

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.
