Abstract: A constant velocity joint configured to be coupled to an interconnecting shaft of a driveshaft includes: an outer race forming a plurality of outer ball tracks; an inner race forming a plurality of inner ball tracks corresponding to the plurality of the outer 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 respectively disposed in spaces formed by the pairs of the outer and inner ball tracks in a state of being respectively housed in the windows. The inner race is coupled to the interconnecting shaft via a ball spline coupling structure to implement a length displacement function through relative axial displacement along an axial direction of the interconnecting shaft. The outer race comprises an inner circumferential surface having a shape of a spherical surface with a first diameter, and a diagonal length of the inner race is smaller than the first diameter.

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.
