Abstract
A constant velocity counter track joint having an outer joint part with outer ball tracks having first tracks opening toward the aperture end and second tracks opening toward the attaching end. The center line of the second tracks, departs, radially inwardly, a first reference radius centered in the point of intersection of a perpendicular line on the tangent at the center line of the ball track and the longitudinal axis. In the inner joint part, the center line of the ball tracks departs, radially inwardly, a second reference radius centered in the point of intersection of a perpendicular line on the tangent at the center line of the ball track and the longitudinal axis. In the outer joint part, the center line of the ball tracks towards the aperture end, moves radially outwardly beyond said first reference radius. In the inner joint part, the center line of the ball tracks towards the attaching end, moves radially outwardly beyond said second reference radius.
