Abstract: An embodiment of a constant velocity joint includes a first rotational member having a generally cylindrical surface. The generally cylindrical surface is defined, at least in part, by a groove portion. The constant velocity joint further includes a grease cover selectively positioned adjacent the first rotational member. An edge portion of the grease cover is positioned within the groove to at least partially retain the grease cover in a desired position.

Abstract: A sealing component constructed of silicone compound for use in high-temperature, high-speed and high-angle applications is disclosed. The disclosed silicone material may also be reinforced with fibers for added stiffness and stability.

Abstract: A method of forming a flexible component includes performing a stress analysis on potential configurations of the component. A desired as-molded shape can be selected from the configurations that were analyzed based upon the stresses resulting from manipulation.

Abstract: A boot for a joint is provided having an aperture and at least one protrusion and at least one indentation disposed about an inside diameter of the aperture.

Abstract: A vent valve for use in a constant velocity joint having a vent aperture in communication with a joint cavity comprises a body portion having a first end and a second end and a plurality of escape pathways extending therebetween. An umbrella shaped flexible retention cap is disposed adjacent the first end of the body portion and the plurality of escape pathways, wherein the retention cap is operative in a normally closed position to cover the plurality of escape pathways and seal the joint from external contaminants, and in response to internal pressure created in the joint cavity functions to bellow outward and expose the plurality of escape pathways to permit air to escape from the cavity.

Abstract: A slip spline boot for use in a constant velocity joint of a vehicle drive line includes a plurality of bellows. The plurality of bellows are arranged between a first and second end of the slip spline boot. The plurality of bellows have a specific peak to peak distance and a specific bellow angle for each of the bellows. The symmetrical boot will have the exact same peak to peak distance and bellow angle for each of the plurality of bellows on the slip spline boot. The slip spline boot is made of a high temperature high stiffness thermoplastic elastomer.

Abstract: A vent valve for use in a constant velocity joint having a vent aperture in communication with a joint chamber comprises a body having a first end and a second end and at least one flat extending therebetween; and an umbrella shaped flexible retention cap disposed adjacent the first end of the body and the at least one flat. The retention cap is operative in a normally closed position to cover the at least one flat and seal the joint from external contaminants, and in response to internal pressure created in the joint cavity, functions to bellow outward and expose the at least one flat to permit air to escape from the chamber. The at least one flat includes a straight-line vent to clean the grease off and away from the vent valve. The vent valve can be made from single or multiple materials, having porous and non-porous properties.

Abstract: A molded boot having an inner layer and an outer layer made from different elastomeric material. Each layer is compatible with the fluid environment to which it is exposed. The dual layer boot provides longer service life with less degradation caused by chemical and environmental exposure.

Abstract: A joint sealing boot comprises a first end affixable to a shaft, and a second end affixable to a boot cover, the second end having a sealing area including at least one sealing bead for sealing the joint and preventing grease egress and contamination ingress.

Abstract: A constant velocity joint vent for use in a constant velocity joint of automotive vehicles. The constant velocity joint vent includes a flapper valve generally having a circular shape. The constant velocity joint vent also includes a first and second assembly post extending from an inside surface of the flapper valve. A circumferential compression limiter is also located on an inside surface of the flapper valve. The flapper valve also includes a sealing bead located at the outer periphery thereof. The flapper valve is connected via the first and second assembly post to a cover that includes an orifice for venting of high pressure gas to the outer atmosphere while also repelling contaminants from entering the constant velocity joint.
