A constant velocity fixed joint. The center line (M) of the outer ball tracks () towards a first side (S) departs, radially inwardly, a reference radius centered in the point of intersection between a perpendicular line on tangents (T) at the center line (M), and the longitudinal axis (L). The center line (M) of the inner ball tracks () towards a second side (S) departs, radially inwardly, a reference radius centered in the point of intersection of a perpendicular line on the tangent at the center line (M), and the longitudinal axis (L). In the outer joint part, from the joint center plane (EM) to the second side (S), the center line (M) moves beyond the reference radius radially outwardly. In the inner joint part (), from the joint center plane (EM) to the first side (S), the center line (M) moves beyond the reference radius, radially outwardly.

Constant velocity joint with small radial movements of the balls

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.

Counter track joint for large articulation angles

A constant velocity twin ball joint, having an outer joint part with outer ball tracks, an inner joint part with inner ball tracks. Circumferentially adjoining pairs of tracks comprise center lines of the outer and inner ball tracks which, when the longitudinal axes are aligned, are positioned in planes which extend parallel relative to one another and are symmetric relative to the longitudinal axes. A ball cage is positioned between the outer joint part and the inner joint part and comprises circumferentially distributed cage windows which each accommodate pairs of balls of adjoining pairs of tracks positioned in parallel planes. The circumferential length of second cage windows for second pairs of balls is smaller than the circumferential length of first cage windows for first pairs of balls.

Twin-ball joint

A constant velocity fixed joint having an outer joint part () with outer ball tracks (), an inner joint part () with inner ball tracks (), the outer ball tracks and the inner ball tracks forming pairs of tracks (), the pairs of tracks each accommodate a torque transmitting ball (). Each two adjoining pairs of tracks comprise outer ball tracks with center lines in planes extending substantially parallel relative to one another, as well as inner ball tracks with center lines in planes extending substantially parallel relative to one another. An annular ball cage () is positioned between the outer joint part () and the inner joint part (). In an aligned joint, centers of the balls are held by the ball cage in the joint center plane and when the joint is articulated, they are guided onto the angle-bisecting plane between the longitudinal axes. The track cross-sections of the outer ball tracks and of the inner ball tracks of each pair of tracks are symmetrical relative to the axes of symmetry which, together with the planes, form identically sized angles opening in opposite directions, and each comprise a common point.
