Abstract: A steering column arrangement for motor vehicles includes a steering column designed to be changeable in terms of its inclination and/or length and a clamping system having plate packs for fixing the steering column in a specific position. The steering column arrangement is designed for increasing the frictional force in the clamping system and/or for locking the clamping system, preferably by way of form-fitting engagement, with structure that acts automatically when a threshold load, acting on the steering column in the direction of its longitudinal axis, is exceeded.

Abstract: A steering column arrangement has a steering column tube unit which is fastened to a vehicle body via a bracket and can be adjusted for comfort purposes. The bracket has two limbs. The steering column tube unit is arranged with a clamping apparatus between the two limbs. In order to adjust the clamping apparatus simply, the limbs are configured with different rigidities.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Furthermore, the invention concerns itself with a method for producing the arrangement. 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 proposed 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.

Abstract: An overload safeguard on a joining connection and a method for producing the overload safeguard are provided. The joining connection comprises an outer joining part having a through-opening and a cylindrical, inner joining part which is acted upon by torque, protrudes through the through-opening in the outer joining part and is frictionally connected to the latter. A countertorque of equal magnitude to the torque of the inner joining part acts on the outer joining part in such a manner that when a torque value corresponding to the maximum permissible frictional force is exceeded, the frictional connection is released and the inner joining part slips in the connection. The inner joining part forms a press fit with the outer joining part and, with its outer circumference, bears against the inner circumference of the through-opening in the outer joining part with a pre-stressing force corresponding to the torque value.

Abstract: 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.
