Abstract
A Rzeppa-type ball spline constant velocity joint includes an outer race, an inner race, and an intermediate race disposed between the inner and outer races and supporting the inner race for angular pivotal movement. The intermediate race and outer race are formed with aligned axial ball channels. A plurality of rows of spline balls are supported by a ball spline cage between the intermediate race and the outer race and extend beyond the ends of the intermediate race to provide free rolling support of the intermediate race along the full limits of the axial stroke of the intermediate race within the outer race.
