Steering spindle arrangement and a method for the production thereof
View Patent ↗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.
1. A steering spindle arrangement, comprising:
a first component remote from a steering wheel and having an end with a wall;
a second component near the steering wheel having a first end with a wall and a second end, wherein the first end of the second component has a largest diameter of the second component;
wherein the first component end and the first end of the second component are frictionally engaged together and wherein the wall of the end of the first component and the wall of the first end of the second component lie directly on each other in a press fit over a region of the frictional engagement;
wherein the second end of the second component has a longitudinal section which tapers in a cone-like manner, and wherein the tapered second end cone-like section is spaced apart axially from the press fit by a portion of the first end of the second component having the largest diameter;
and wherein the end of the first component is engageable with an inner wall of the tapered second end cone-like section of the second component at an end of a displacement path of the first component within the second component.
2. The steering spindle arrangement according to claim 1 , wherein the first and second components are of tubular design with a circular cross-section.
3. The steering spindle arrangement according to claim 1 , wherein both the first and second components are hollow, and wherein at least the end of the first component and the first end of the second component have a polygonal shape cross-section.
4. The steering spindle arrangement according to claim 1 , wherein the walls of the ends bear against each other in a play-free manner over their full extent.
5. The steering spindle arrangement according to claim 1 , wherein the press fit is formed by plastic expansion of an inner wall and by elastic, resilient deformation of an outer wall.
6. The steering spindle arrangement according to claim 5 , wherein the inner wall is beveled or rounded at an end edge.
7. A method for producing a steering spindle arrangement, comprising the steps of:
frictionally connecting a first component to a second component by inserting an end of the first component into a first end of the second component and pressing a wall of the end of the first component against a wall of the first end of the second component to form a press fit over a region of the frictional connection, wherein the first end of the second component has a largest diameter of the second component; and
axially positioning the end of the first component from a section of a second end of the second component, the section tapering in a cone-like manner and spaced apart axially from the press fit by a portion of the first end of the second component having the largest diameter, wherein the end of the first component is engageable with an inner wall of the tapered second end cone-like section of the second component at an end of a displacement path of the first component within the second component.
8. The method according to claim 7 , wherein the end of the first component and the first end of the second component are connected to each other in a form-fitting manner when frictionally connected together.
9. The method according to claim 7 , wherein the first component is hollow and is expanded by fluidic internal high pressure and is pressed onto the wall of the second component, the second component being expanded elastically and the first component being expanded plastically.
