ABSTRACT:
A driveshaft (1) for driving the wheels of a motor vehicle has two constant velocity joints (2, 3) and a connecting shaft (4). The two constant velocity joints (2, 3) are provided in the form of constant velocity fixed joints. The plunging assembly required to change the longitudinal distance (L) includes a plunging journal (21), formed onto the second joint part (20) of the second constant velocity joint (3), and a plunging portion (26) of the connecting shaft (4). The shaft (4) surrounds the plunging journal (21) and is provided in the form of a tubular shaft. The cross-section of the plunging portion (26) has the shape of a corrugated shaft. Each outer corrugation peak, in the bore of the plunging portion (26), includes a second running groove (29) positioned opposite a running groove (22) in the plunging journal (21). Balls (23) are rollingly arranged between the two running grooves (29, 22) and held by a cage (24). By providing the plunging portion (26) of the connecting shaft (4) in the form of a corrugated tube, it is possible to use less mass and to increase the strength values as a result of the forming operation. At the same time, the vibration behavior is improved.
