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 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 bearing apparatus for wheels includes an outer ring, a hub shaft, rolling elements, a seal attached to a vehicle-outer-side part of the outer ring, a rotating slinger attached to the vehicle-outer-side part of the hub shaft and contacted by the seal, and a fixed slinger attached to a vehicle-outer-side outer periphery of the outer ring and contacted by the seal. An outer peripheral surface of the outer ring has a non-plated surface portion provided at a vehicle-outer-side end of the outer ring and a plated surface portion that is continuous with the non-plated surface portion. The fixed slinger has an inner cylindrical portion externally fitted over and attached to the non-plated surface portion. The seal has an inner lip that contacts the rotating slinger and an outer lip that contacts the inner cylindrical portion.

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.

A wireless sensor for a wheel end assembly of a heavy-duty vehicle is provided. The wheel end assembly includes a wheel hub and a hub cap mounted on the wheel hub. The sensor includes mounting means disposed in the hub cap. Sensing means are mounted on the mounting means to sense at least one condition of the vehicle. A processor is mounted on the mounting means and is electrically connected to the sensing means to process data from the sensing means. Communication means are mounted on the mounting means and are electrically connected to the processor to communicate the processed data to a user. An electrical energy storage device is mounted on the mounting means and is electrically connected to the sensing means, the processor and the communication means, enabling the sensor to be independent from the vehicle power supply. The sensor also accommodates components of a tire inflation system.

The present invention provides a non-rotating center cap for use with vehicle wheel. The present invention comprises a support, an interlocking device, an ornamental object, and a sealer cap. The support is the part of the non-rotating center cap that affixes to the center bore of a vehicle wheel, the interlocking device is mounted in a depression formed on the support. The interlocking device biases the orientation and prevents the rotation of an ornamental object that is connected to it. The sealer cap is connected to the support, the sealer cap protects the ornamental object from water, dust, debris and oil, the sealer cap prevents movements of the ornamental object that could be caused by winds when the vehicle is in motion. The ornamental object does not rotate when the vehicle is in motion, which allows the ornamental object to be readily visible.

Provided is a hub unit bearing wherein a cover can be firmly fitted with an outer ring member, and it is difficult for foreign matter to enter inside through a water drainage hole formed in the cover. The cover that covers the inside end section in the axial direction of the hub unit bearing includes a disk section, a small-diameter cylindrical section bent in the axial direction from the outer perimeter edge section of the disk section and a large-diameter cylindrical section. A cut and raised section that is cut and raised toward the inside in the radial direction is formed in the small-diameter cylindrical section, and a water drainage hole that passes through from inside to outside the cover is provided in the portion that is cut and separated from the small-diameter cylindrical section.
