OG exemplary drawing
 
1. A motor vehicle drive shaft, comprising:
a receptacle-tube component with a receptacle internal diameter;
a push-fit component with a push-fit external diameter; and
a connection component, wherein
the push-fit external diameter is smaller than or equal to the receptacle internal diameter,
the receptacle-tube component and the push-fit component are rotatable about a common drive shaft rotation axis and extend along the common drive shaft rotation axis in a longitudinal direction,
the connection component, by way of a receptacle connection, is connected in a torque-conducting manner to the receptacle-tube component,
the connection component, by way of a push-fit connection, is welded to the push-fit component, wherein at least one end of the connection component is inserted into an interior of the push-fit component such that the push-fit component is arranged radially outside of the at least one end of the connection component,
the receptacle connection between the connection component and the receptacle-tube component is configured as a combined friction-fitting/form-fitting shaft-to-hub connection,
the connection component has a knurling,
the receptacle-tube component has a receptacle connection region which, together with the knurling, forms the friction-fitting/form-fitting shaft-to-hub connection to the connection component at the region of the knurling of the connection component, and
the receptacle-tube component and the push-fit component are connected to one another via the connection component for transmitting torque.
