Abstract
A tripod constant velocity universal joint having an annular outer member, an inner member and three multiple component rollers. The interior surface of the outer member has three longitudinal lobes forming opposing pairs of parallel longitudinal guideways which are engaged by the multiple component rollers. The inner member is centrally positioned within the outer member and has three trunnions extending radially into the three longitudinal lobes. A multiple component roller is pivotally attached to each of the trunnions. Each multiple component roller has oppositely disposed pairs of elongated rollers, each of which engages an adjacent guideway that corresponds to its trunnion. The axis of rotation of the elongated rollers is substantially perpendicular to its adjacent guideway. Each elongated roller is mounted such that it can be axially displaced along its axis of rotation.
