Abstract
An anti-shudder tripod constant velocity universal joint having an outer member and an inner member. The outer member has an internal cavity having three lobes, each of which has a pair of face-to-face longitudinal guideways for a roller. The inner member has three radially extending trunnions which individually extend into a respective one of the three lobes. The rollers are a multiple component roller having an inner race member pivotably attached to each trunnion by mating spherical surfaces. A roller member is rotatably attached to each inner race member by a plurality of roller bearings disposed therebetween. The roller member is free to move axially with respect to the inner race member along the roller bearings when the inner member is angularly disposed relative to the outer member to keep the rollers in the guideways. A circumferential lip and a retainer ring attached to the inner race member captivates the roller member therebetween and maintains the roller member in rolling contact with the roller bearings.
