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 safety steering column for a motor vehicle, with a casing tube which is arranged concentrically to a steering shaft and is fastened to the vehicle body and which, in the event of an axial impact action, can be shortened while at the same time absorbing energy. The casing tube consists of two casing-tube parts and the displacement force between the two casing-tube parts can be set. Arrange between the two casing-tube parts is a connecting element which is fastened to one of the casing-tube parts and is pressed with a predetermined force into a groove introduced into the other casing-tube part.

Safety steering column

A steering spindle for a motor vehicle has a plug-in connection in which a splined shaft profile extends axially and is arranged at the end of a shaft, and a receiving tube which receives the splined shaft profile and is provided along its inner circumference with a corresponding splined hub profile. Furthermore, the steering spindle has, in the region of the plug-in connection, a plastic layer which extends at least along certain axial regions and fills clearances between the inner wall of the receiving tube and the splined shaft profile. The splines of the one part, arranged in the region of the receiving tube, are formed uninterruptedly in the axial direction and are an undersized portion in the circumferential direction with respect to the grooves of the other part. The splines of the one part are provided with the plastic layer of elastomeric plastic bridging this undersize portion. The plastic layer has an axial portion which is greater than the amount of maximum relative movement between the shaft and the receiving tube.
