Abstract

A driveshaft having at least one counter-track joint, the joint having an outer joint part (11), an inner joint part (21), torque-transmitting balls (36) accommodated in pairs of tracks, and a ball cage with cage windows in which the balls are held in a common plane. First outer tracks and first inner tracks form first pairs of tracks which diverge from one another when viewed in a first axial direction towards the connection end of the inner joint part (21) and hold first balls. Second outer tracks and second inner tracks form second pairs of tracks which diverge from one another when viewed in a second axial direction towards the connection end of the outer joint part 11 and hold second balls. The first pairs of tracks are positioned radially opposite each other and the second pairs of tracks are positioned radially opposite each other.
