A passenger automotive vehicle wheel bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient radial or side impact (such as a pothole or curb impact) to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and/or vibration condition in the bearing assembly. Wheel bearing assemblies according to the invention provide increased impact Brinell resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.

In another embodiment, there are two each pyramid shaped formations located on each of several thrust bumpers, which are held in position by a retainer.
A composite drain plug for an automobile engine. The drain plug is made up of a hollow metal sleeve that is flanged at one end and closed at the other end. There is a core portion filling the hollow sleeve and having a head portion and a stub flange adjacent the flanged end of the sleeve. A circumferential sealing bead is bonded to the stub flange. The core portion is a glass-filled polymer and the sealing bead is made from a material which includes a cross-linked elastomer dispersed in a thermoplastic carrier.

MECHANICAL END FACE SEAL WITH ULTRAHARD FACE MATERIAL
An end face seal having two thin, opposed faces of a composite PDC/tungsten carbide or like material for example of a thickness of from about 2 to 5 mm to about 10 to 15 mm, brazed or adhesively adhered by an epoxy resin to a substrate of tungsten carbide or silicon carbide/nitride formed in a ring shape. Thereafter, the PDC layer is finish lapped to a flatness of about 1 to about 10 helium lightbands, with a rough lapping to 3 or 4 helium lightbands, and a finish lapping of about 1 helium lightband.

Composite seals, seal structures and related methods
According to one embodiment, a composite seal may include a first, substantially annular seal element having an upper body portion, a neck portion, and an axial protrusion. The upper body portion includes opposing inclined surfaces extending toward the neck portion defining a first angle. The axial protrusion includes opposing inclined surfaces extending toward an axial end of the axial protrusion defining a second angle, wherein the first angle and the second angle are substantially similar. The composite seal may further include a second, substantially annular seal element having a mouth portion, a neck portion and a recess portion, wherein the axial protrusion is configured to be complementarily engaged with the recess portion in an interlocking manner.
A sealing system for sealing high liquid pressure and containing a wiper lip (68 or 69a and 68a) in either of two forms. The light pressure seal includes a seal casing, a seal body (40) including a lip seal (54), a snap ring (66) and a plastic back-up ring (42), and the wiper lip seals on either a radial (68a) or an axial surface (69a). The casing may have radial (32) and axial (30) flanges or a radial flange only. The space (85) between the two seals may be filled with grease.
A fluid seal assembly including a specialized protective filter unit which is adapted for use with a fluid seal, as well as to the combination of a protective filter unit with an associated seal unit to form a complete seal assembly. The seal provides increased reliability, particularly in those specialized seals wherein high internal pressure and the possibility of particulate contaminants are present.
A bearing assembly for a shaft including an inner ring that mounts on the shaft and an outer ring disposed concentrically about the inner ring. Ball bearings are interposed between the inner and outer rings. Fingers are formed on one side of the inner ring and they extend axially with adjacent fingers defining longitudinally extending slots. An outwardly opening notch is formed in each of the fingers to create an outwardly opening circumferential groove around the inner ring. A compressible annular locking collar is positioned circumferentially around the fingers. A fastener screw is operable to compress the fingers into locking engagement with the shaft. A first elongated locking rod extends through the locking collar and into an outwardly opening notch in one of the fingers to secure the locking collar against axial movement relative to the fingers. A second locking rod extends through the locking collar to fit into a slot between a pair of fingers to secure the locking collar against circumferential movement relative to the fingers.
A controlled leakage seal assembly (18) having a first stationary portion (20) adapted to be connected in substantially fluid-tight relation to a source of drilling fluid and a second portion adapted to be connected in substantially fluid tight relation to a rotary portion (22) including a washpipe (70). The seal includes a first housing (26) and a stack of radially inwardly extending, spaced apart annular stators (64a, 64b), and a second seal housing (22) and stack of spaced apart radially outwardly extending annular rotors (78a, 78b) interleaved with one another. The seal assembly, a cartridge, permits the first and second housings to rotate relative to each other in substantially fluid-tight relation except for drilling fluid entering an outlet region at greatly reduced pressure. In a preferred embodiment, the seal is held by a sleeve that permits the cartridge to be removed and replaced while the fluid connections to the sleeve remains.

A contaminant-resistant bearing assembly includes a multi-lip seal with an extended shroud supported from the outer ring and projecting adjacent a stepped inner ring shoulder. A steel slinger supported from the inner ring is offset outwardly adjacent the shroud and includes a radially outer edge terminating closely adjacent the connection of the seal shroud to the outer ring. The slinger includes an outer portion angled inwardly from the radial direction and supporting a lip seal which contacts an angled portion of the seal shroud at a central location between the rings. A primary step machined on the inner ring prevents the slinger from being pushed into the seal.
b) are the only portions of the flange (56) in contact with the vehicle when the support member (14) is secured to the vehicle, reducing the contact area between the flange (56) and the vehicle, and reducing impact forces transferred to the bearings. A portion of the flange (56) may act as a spring member, enabling the flange (56) to flex in response to an impact load experienced by the wheel bearing assembly (11). This enables the flange (56) to absorb a portion of the side impact load, thereby attenuating the portion of the load transmitted to the bearings. A wheel bearing assembly (10) incorporating the support member (14) is also disclosed.
An elastomeric bearing having inner and outer races and a novel core. The novel core has a plurality of resilient laminae and a plurality of non-resilient laminae interleaved with one another. Each of the lamina has an axially inner cylindrical portion of a given diameter, an axially outer cylindrical portion of a greater diameter than the given diameter and, lying between the inner and outer laminae, an angled portion joining the axially inner and outer laminae to each other. The laminae are continuous and of one piece. In this way, the elastomeric bearing has comparatively small resistance to torsional movement, but great resistance to both radial and axial movement.
A heavy duty composite oil seal with an outer cup and a plastic inner cup. The outer cup includes a major diameter mounting flange portion terminating in a curl, a minor diameter wear sleeve portion, and a transition portion joining the major and minor diameter portions. There is an elastomeric seal body and an embedded stiffener, with the elastomeric seal body having a sealing lip contacting the inner axial surface of the wear sleeve portion. There is a plastic inner cup member with an axial flange substantially co-extensive with the mounting flange and entrapped along the major diameter flange portion between the curl portion and the transition portion of the outer cup. The inner cup also has a radially extending flange that engages a radial portion of the elastomeric seal body. The plastic inner cup member has plural, evenly spaced diagonal braces extending between and joining the axial flange and the radial flange of the inner cup.
