Abstract
A drive aft has two universal joints. The universal joint (1) is connected to a sliding sleeve (9). The other universal joint carries a sliding journal (8). The sliding journal (8) and the sliding sleeve (9) engage one another in a rotationally fast way via teeth (11, 22). The teeth (11, 22) are longitudinally displaceable relative to one another in the direction of a longitudinal axis (10). In order to prevent the driveshaft, in the fitted condition, from falling apart after having suffered a fracture, an anti-disengagement member is provided. The member includes an annular stop (13) arranged at the end of the sliding journal (8). The stop (13) may be fitted through an aperture (15) in the joint yoke (4) of the first universal joint (1). The stop (13) stops against a suitable face of the inner longitudinal teeth (22) when the sliding sleeve (9) and the sliding journal (8) are moved apart by a change in length distance (16).
