Patent ID: 6872143

Claim:
A driveshaft having two constant velocity joints and an intermediate shaft, wherein at least one of the joints is a constant velocity fixed bail joint in the form of a counter-track joint, the joint comprising: an outer joint part with outer tracks; an inner joint part with inner tracks; torque-transmitting balls accommodated in pairs of tracks; and a ball cage with cage windows in which the balls are held in a common plane and are guided on to the angle-bisecting plane when the joint is articulated, wherein first outer tracks, together with first inner tracks, form first pairs of tracks which diverge from one another viewed in a first axial direction (R 1 ) towards a connection end of the inner joint part and hold first balls, wherein second outer tracks, together with second inner tracks, form second pairs of tracks which diverge from one another in a second axial direction (R 2 ) towards a connection end of the outer joint part and hold second balls, wherein said first axial direction (R 1 ) is opposite to said second axial direction (R 2 ), wherein first pairs of tracks are positioned radially opposite other first pairs of tracks and second pairs of tracks are positioned radially opposite other second pairs of tracks, wherein, in said counter-track joint, first pairs of tracks and second pairs of tracks are alternately arranged around the circumference of the counter-track joint, and wherein the counter-track joint comprises eight pairs of tracks.
