Abstract

A constant velocity joint configured to be coupled to an interconnecting shaft includes: an outer race forming a plurality of outer ball tracks; an inner race forming a plurality of inner ball tracks; a ball cage interposed between the outer race and the inner race and forming a plurality of windows; and a plurality of torque transmitting balls. The outer race and the inner race are configured to implement an angular articulation function that allows for relative angular displacement therebetween, and the inner race is coupled to the interconnecting shaft via a ball spline coupling structure to implement a length displacement function. The ball spline coupling structure includes: an outer spline groove; an inner spline groove; a sleeve member interposed between the inner race and the interconnecting shaft; and a plurality of spline balls, with said spline balls being accommodated within a sleeve window formed on the sleeve member.
