Abstract

An axle attachment includes a guide element having a guide-side attachment region that is curved in a concave manner and a guide-side fixing region adjoining the guide-side attachment region along the curvature line, and a clamping element having a clamping-side attachment region that is curved in a concave manner and that is arranged opposite the guide-side attachment region, and a clamping-side fixing region. A fixing element engages into a guide-side fixing region and into an opposing clamping-side fixing region and forces the regions against each other in order to fix an axle body to the axle attachment in a force-fitting manner.

First claim

The invention claimed is:

1. An axle attachment, comprising:
a guide element; and
a clamping element;
wherein the guide element has a guide-side attachment region that is curved in a concave manner, and a guide-side fixing region adjoining the guide-side attachment region;
wherein the clamping element has a clamping-side attachment region that is arranged opposite the guide-side attachment region, and a clamping-side fixing region;
wherein a fixing element engages into a guide-side fixing region and into an opposing clamping-side fixing region and forces the guide-side fixing region and clamping-side fixing region against each other to fix an axle body to the axle attachment in a force-fitting manner; and
wherein the guide-side attachment region at least one of:
follows at least one of an elliptical arc and a circular arc which in a first state of the guide-side attachment region spans a first angle of the arc; and
includes a polyhedral section, which in a first state of the guide-side attachment region spans a first angle of an arc; and

wherein in a second state of the guide-side attachment region a second angle of the arc is within a range of 1.01 times to about 1.5 times the first angle of the arc.

2. The axle attachment of claim 1 , wherein at least one of the guide-side attachment region and the clamping-side attachment region comprises a cylinder-shape, and wherein the attachment regions have an extension along a cylinder axis that is in a relationship of about 0.5 to about 3 to a radius of curvature of the guide-side attachment region.

3. The axle attachment of claim 2 , wherein the relationship of the extension along the cylinder axis to the radius of the curvature of the guide-side attachment region is 0.75 to 2.

4. The axle attachment of claim 3 , wherein the relationship of the extension along the cylinder axis to the radius of the curvature of the guide-side attachment region is 0.9 to 1.5.

5. The axle attachment of claim 2 , wherein the guide-side attachment region in the first state has a first radius of curvature, and in the second state has a second radius of curvature that is smaller than the first radius of curvature.

6. The axle attachment of claim 5 , wherein in the first state of the guide-side attachment region the first angle of the arc is about 170° to about 195°.

7. The axle attachment of claim 6 , wherein in the first state of the guide-side attachment region the first angle of the arc is 175° to 185°.

8. The axle attachment of claim 7 , wherein in the first state of the guide-side attachment region the first angle of the arc is 175° to 182°.

9. The axle attachment of claim 6 , wherein in the second state of the guide-side attachment region the second angle of the arc is 1.05 times to 1.3 times the first angle of the arc.

10. The axle attachment of claim 9 , wherein in the second state of the guide-side attachment region the second angle of the arc is 1.1 times to 1.2 times the first angle of the arc.

11. The axle attachment of claim 9 , wherein a force applied by the fixing element in the second state of the guide-side attachment region acts substantially perpendicular to the second radius of curvature of the guide-side attachment region.

12. The axle attachment of claim 11 , wherein the clamping element has at least one of a projection at the ends of the clamping-side attachment region that engages into a corresponding recess of the guide element in a form-fitting manner, and a recess at the ends of the clamping-side attachment region that receives a corresponding projection of the guide element in a form-fitting manner.

13. The axle attachment of claim 12 , wherein the clamping element includes a projection that at least in a certain area is wedge-shaped and that is received into a recess on the guide element, wherein the recess is wedge-shaped at least in a certain area and that, when the clamping element is braced, is urged against the guide element such that the projection exerts a force onto an axle body to be fixed along the second radius of curvature.

14. The axle attachment of claim 11 , wherein the clamping element includes a recess that is form-fitting engaged with an axle body, thereby securing the axle body against rotation relative to the clamping element.

15. The axle attachment of claim 12 , wherein a side of the guide-side fixing region facing away from the clamping element is curved in a concave manner, and wherein an adapter element rests on the guide-side fixing region with a rounded surface and transmits a force applied by the fixing element to the guide-side fixing region.

16. The axle attachment of claim 15 , wherein the clamping element includes four clamping-side fixing regions.

17. The axle attachment of claim 16 , wherein the clamping element may be fixed to the axle body in a substance-to-substance bond.

18. The axle attachment of claim 17 , wherein the guide-side attachment region is configured for a substance-to-substance bond between the guide-side attachment region and the axle body.

19. The axle attachment of claim 1 , wherein the guide-side attachment region in the first state has a first radius of curvature, and in the second state has a second radius of curvature that is smaller than the first radius of curvature.

20. The axle attachment of claim 1 , wherein in the first state of the guide-side attachment region the first angle of the arc is about 170° to about 195°.

21. The axle attachment of claim 1 , wherein in the second state of the guide-side attachment region the second angle of the arc is 1.05 times to 1.3 times the first angle of the arc.

22. The axle attachment of claim 1 , wherein a force applied by the fixing element in the second state of the guide-side attachment region acts substantially perpendicular to the second radius of curvature of the guide-side attachment region.

23. The axle attachment of claim 1 , wherein the clamping element has at least one of a projection at the ends of the clamping-side attachment region that engages into a corresponding recess of the guide element in a form-fitting manner, and a recess at the ends of the clamping-side attachment region that receives a corresponding projection of the guide element in a form-fitting manner.

24. The axle attachment of claim 1 , wherein the clamping element includes a projection that at least in a certain area is wedge-shaped and that is received into a recess on the guide element, wherein the recess is wedge-shaped at least in a certain area and that, when the clamping element is braced, is urged against the guide element such that the projection exerts a force onto an axle body to be fixed along the second radius of curvature.

25. The axle attachment of claim 1 , wherein the clamping element includes a recess that is form-fitting engaged with an axle body, thereby securing the axle body against rotation relative to the clamping element.

26. The axle attachment of claim 1 , wherein a side of the guide-side fixing region facing away from the clamping element is curved in a concave manner, and wherein an adapter element rests on the guide-side fixing region with a rounded surface and that transmits a force applied by the fixing element to the guide-side fixing region.

27. The axle attachment of claim 1 , wherein the clamping element includes four clamping-side fixing regions.
