Motor vehicle drive shaft and method for producing it

A method for producing a motor vehicle drive shaft, the method comprising:

• providing a push-fit component, a receptacle-tube component, and a connection component, wherein an external diameter of the push-fit component is smaller than or equal to an internal diameter of the receptacle component;
• providing the connection component with a knurling;
• press-fitting the connection component provided with the knurling into the receptacle-tube component so as to configure a friction-fitting/form-fitting shaft-to-hub connection between the connection component and the receptacle-tube component;
• inserting at least one end of the connection component into an interior of the push-fit component such that the push-fit component arranged radially outside of the at least one end of the connection component;
• and
• welding the push-fit component to the connection component, wherein
• 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, and
• the receptacle-tube component and the push-fit component are connected to one another via the connection component for transmitting torque.

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 connected to the push-fit component,
• the push-fit connection between the connection component and the push-fit component is configured as a combined friction-fitting/form-fitting shaft-to-hub connection, wherein at least one of the push-fit component or the connection component has a knurling in a region of the push-fit connection to form the combined friction-fitting/form-fitting shaft-to-hub connection, wherein one end of the push-fit component is inserted into an interior of a first end of the connection component at least in the region of the push-fit connection,
• the receptacle-tube component and the connection component are welded together to form the receptacle connection, wherein one end of the receptacle-tube component is inserted into an interior of a second end 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.
