Abstract
A plunging, constant-velocity, tripode universal joint comprising a first rotary member ( ) having three trunnions ( ), a roller ( ) having a cylindrical bore mounted on a spherical surface ( ) on each trunnion so that the cylindrical bore engages the spherical surface and so that each roller can rotate, tilt and slide relative to its supporting trunnion, a second rotary member ( ) having three grooves parallel to its rotary axis, each roller being engaged with one of the grooves, the engagement between each roller and track surfaces in its associated groove being at three points such that the orientation of the roller with respect to the second member is determined solely by said engagement and wherein when the joint is transmitting torque each roller ( ) is only in contact with the track surface(s) ( ) through which the torque is being transmitted.
