Abstract

A counter track joint includes an outer joint part with first and second outer ball tracks, an inner joint part with first and second inner ball tracks. The first outer and inner ball tracks, together, form first pairs of tracks, which, when the joint is in an aligned position, widen towards the aperture end of the outer joint part and each accommodate first torque transmitting balls. The second outer and inner ball tracks, together, form second pairs of tracks which, when the joint is in the aligned position, widen towards the attaching end of the outer joint part and which each accommodate second torque transmitting balls. The centers of the balls of the first pairs of tracks each define a first track center line. The first track center line, in the direction from the central joint plane towards the attaching end extends radially inside a first reference arc.
