Abstract: A coupling arrangement for two axially aligned shaft sections is obtained through two splined profiles, one attached to each shaft through a tensioning arrangement that eliminates relative rotation between the two shaft sections while permitting longitudinal movement therebetween. One shaft section connected to one end of the tensioning device and the other shaft section connected to another end of the tensioning device and wherein the other end of the tensioning device operates to cause one of the splined profiles which is slotted to grasp the other splined section to provide for the relative non-rotational drive and the axial longitudinal shifting of the shaft sections.

Abstract: A ball joint which includes a ball pin that is connected with a coaxial strut, a bearing part of synthetic material, a ball housing surrounding the bearing part, and a bellows seal, particularly as used with front axles of motor vehicles equipped with a braking support. The ball housing is equipped with abutment surfaces which abut at rubber spring elements having a progressive spring characteristic while the rubber spring elements project from an outer housing which has a spacing on all sides from the ball housing.
