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.
