Abstract: A slip type driveline assembly with a one piece sealing member to prevent loss and contamination of lubricant. The slip type assembly is generally of a sliding spline design. A spline plug is fitted into a slip yoke with an internal spline that generally mates with the external spline of the spline plug. A tube and weld yoke assembly is generally pressure fit and welded to the spline plug. Universal joint assemblies are attached to each yoke completing the assembly. The splined cavity within the slip yoke generally contains lubricants and is sealed by a plug and a seal which keeps the lubricants in and contaminants out. The sealing member is made of a resilient material and is of one piece construction. The sealing member has a cylindrical wall and integral radially inwardly extending circumferential annulus. The wall and annulus generally complement and mate with the cylindrical end of the slip yoke that has a groove on its surface to receive the annulus.

Abstract: A drive shaft assembly particulary suited for power transmission in motor vehicles wherein a drive shaft has a universal joint connected to at least one end thereof with a sealing boot attached in sealing engagement between the outer joint member of the universal joint and the drive shaft. The invention is particularly directed to the provision of an elastomeric cover on the outer surface of the drive shaft, the elastomeric cover extending along the shaft from the exterior of the sealing boot to within the region enclosed by the boot in order to provide an arrangement which is resistant to damage, corrosion, and wear and which may be conveniently fitted and assembled. The elastomeric cover may be provided with internal ribs to establish ventilation channels for the shaft assembly.
