Abstract
A driveshaft assembly has external profiled teeth at its end and a slide-on hub with a shaft bore with corresponding inner profiled teeth. A first securing mechanism form-fittingly engages a groove or thread radially cut into the profiled teeth and provided at the free end of the driveshaft and axially supporting the hub in the direction of the end of the driveshaft. External profiled teeth, which are provided at the driveshaft and which, when the hub is fully slid on to the driveshaft while being in contact with the first securing mechanism, extend axially relative to the shaft shank and beyond the length of the hub. A second securing mechanism, with a radially undisturbed profile of the profiled teeth, is supported on the run-out of the profiled teeth or on an adjoining conical face of the driveshaft. The second securing mechanism is plastically formed in-situ and axially supports the hub in the direction of the shaft shank of the driveshaft.
