A motor vehicle drive shaft has a receptacle tube component with a receptacle internal diameter and a push-fit component with a push-fit external diameter. The push-fit external diameter is smaller than or equal to the receptacle internal diameter. The receptacle tube component and the push-fit component can be rotated about a common drive shaft rotational axis and extend along the latter in a longitudinal direction. The receptacle tube component and the push-fit component are connected to one another for the transmission of torque. A connecting component is provided, wherein the connecting component is connected in a torque-conducting manner to the receptacle tube component by way of a receptacle connection. The connecting component is connected to the push-fit component by way of a push-fit connection. At least one of the two connections is configured as a combined frictionally locking and positively locking shaft/hub connection.

Motor vehicle drive shaft and method for producing it

A method for producing a shaft-hub connection in which a shaft component and a hub component are placed into a joined state in the form of a frictional shaft-hub connection. The shaft component has a toothed region having teeth with a height H, and the hub component has a mating toothed region having a mating region internal diameter d. The hub component is pushed onto the shaft component in a longitudinal direction to produce the frictional shaft-hub connection and in the process geometrically reproduces the toothed region in the mating toothed region. The mating toothed region passes over a cylindrical centering region with an outer diameter D before coming into contact with the toothed region. The outer diameter D is at most 0.2 mm and at least 0.005 mm smaller than the mating region inner diameter d. The centering region has a length L greater than 1 mm.
