An assembly having a retaining element, an outer race of a constant velocity joint, and a shaft of an outboard drive axle that is axially joined to the outer race. The shaft has an external groove circumferentially formed on its external surface for receiving the retaining element. The external surface of the shaft supports a new generation wheel bearing assembly and a wheel hub that is non-rotatably coupled to the external surface of the shaft. The retaining element engages the external groove of the shaft and retains the wheel hub without requiring a preload on the bearing. The wheel hub is held in place by the retaining element and the shaft, wherein the wheel bearing assembly is retained by the wheel hub, thereby allowing the retained wheel hub to be rotatably drivable within the wheel bearing assembly by the constant velocity joint.

Shaft and wheel hub retention assembly

A dynamic damper for absorbing vibrations in a rotary driveshaft, including a mass member assembly having a plurality of mass members, each mass member having an inner surface, an outer surface, and an affixing member to affix the mass member to another mass member of the assembly, the mass member assembly being affixable to a rotary shaft.

Durability of elastomeric bellows-type suspension and drivetrain components, particularly constant velocity joint boots, is improved by coating the elastomeric boot with a thin, flexible, and lubricious coating formed by curing the admixture of epoxy resins, curing agents, an unsaturated polymerizable monomer, a free radical polymerization and/or grafting initiator, and a non-fugitive solid lubricant. The coating strongly adheres to the elastomer and greatly increases the longevity under severe operating conditions.

Constant velocity joint boot and method of making the same

A transmission joint sealing boot comprising a flexible diaphragm member having a passageway extending therethrough, a first end defining an opening, an annular second end disposed opposite the first end, a flexible arcuate section connecting the first end and the annular second end of the flexible diaphragm member, the first end further including an inner surface and an outer surface, a bellows member having a passageway extending therethrough, the bellows member including a first end defining an opening, a second end disposed opposite the first end, and an intermediate bellows segment having a convoluted section disposed between the first end and the second end and connecting the first end and the second of the bellows member, wherein the second end defines an opening for receiving the first end of the flexible diaphragm member and the second end further including an inner surface and an outer surface, a magnetically active weld sleeve having an inner surface correspondingly shaped to mate with the outer surface of the first end of the diaphragm member such that the magnetically active weld sleeve is received on and abuts against the outer surface of the first end of the diaphragm member and an outer surface correspondingly shaped to mate with the inner surface of the second end of the bellows member such that the magnetically active weld sleeve and first end of the diaphragm are received within the opening of the bellows member whereby the magnetically active weld sleeve is disposed between the diaphragm member and the bellows member such that when the magnetically active weld is exposed to an electromagnetic field of current, the magnetically active weld sleeve melts and subsequently fuses the diaphragm member, the bellows member and weld sleeve together.
