ABSTRACT:
A driveshaft has two shaft parts (4, 6) which provide a coupling. To facilitate the operation of coupling the two shaft parts (4, 6) to one another, the coupling operation is divided into two phases. A member initially aligns the two shaft parts (4, 6) along a common longitudinal axis (13). Also, the shafts are rotationally fast connected between the shaft parts. A centering journal (20) centers the two shaft parts (4, 6) relative to one another on a common longitudinal axis (13). The centering journal centers the bore (16) of the first profiled tube (12) with a relative rotation of the two shaft parts (4, 6) continuing to be possible. When inserting the two shaft parts (4, 6) into one another, the first coupling part (19), which is firmly connected to the first profiled tube (12), via its claws approaches the claws of the second coupling part (40). The second coupling part (40) is displaceable on the second profiled tube (28) via a setting sleeve (34) against the force of a spring (38). When the first coupling part (19) abuts the second coupling part (40), the second coupling part is then displaced against the force of the spring (38). When the drive is switched on and when the two shaft parts (4, 6) reach a relative position relative to one another, the claws and gaps of the two coupling parts (19, 40) are moved into matching positions. The compression spring (38) pushes the second coupling part (40) towards the first universal joint (.epsilon.), so that the claws engage one another and transmit torque.
