A steering spindle arrangement having a first component remote from the steering wheel and a second component near the steering wheel, with one of the mutually facing ends of the one component dipping into the hollow end of the other component, and with the two ends being connected frictionally to each other, is disclosed. Furthermore, a method for producing the arrangement is disclosed. In order, in a simple manner, to obtain as specific a definition as possible of the absorption by the steering spindle of the deformation energy in the event of a crash while ensuring that the arrangement is durable and directly transmits the steering moment, it is provided that the walls of the two ends lie directly on each other in the form of a press fit over the region of the frictional connection.

Steering spindle arrangement and a method for the production thereof

The invention relates to a casing tube of a steering column of a motor vehicle, the tube comprising two telescopic tube sections which are connected frictionally to each other in a press fit and, in the event of a crash, can be displaced relative to each other over an axial displacement path. In order, in the case of a vehicle accident, in a simple manner firstly to prevent a hard impact of the driver on the steering wheel and secondly to achieve the greatest possible absorption of impact energy, the tube sections are connected frictionally to each other over the entire displacement path. Furthermore, a method for producing a casing tube of this type is disclosed.

Casing tube of a steering column of a motor vehicle and a method for producing the casing tube

A method and device for connecting two components by way of high fluid pressure are provided, the components being pushed onto one another, and the two components then being pressed against one another by way of the high pressure. In order to interconnect components in a relatively simple and controlled manner without any limitation with regard to the minimum size of an inside diameter of the components and with regard to the design of the inner component, the outer component, the material of which has a yield point which is lower than that of the inner component, is plastically deformed by high-pressure action acting on the sliding assembly from outside, the inner component being elastically deformed. An assembly of the components is also provided.
