ABSTRACT:
A telescopic tripot universal joint comprises an outer drive member having three radial drive channels which include two flat longitudinal drive tracks, an inner drive member having three radial trunnions having cylindrical bearing surfaces, and three intermediate drive rollers disposed in the respective radial drive channels and rotatably and slideably mounted on the respective radial trunnions. Each intermediate drive roller has a radial bore which is convexly shaped so as to permit a slight universally pivoting or wobbling movement of the intermediate drive roller on the radial trunnions and the radial trunnions have stops for limiting outward movement of the drive rollers during operation of the telescopic tripot universal joint. A full complement of cylindrical needle rollers is disposed between the convexly shaped radial bore of each intermediate drive roller and the cylindrical bearing surface of the respective trunnion.
