Claims
- 1. An arrangement for attaching an assembly component with variable spacing to an understructure, said arrangement comprising:
an assembly component having at least one bore for receiving a fastening element, a material region of a height surrounding each at least one bore; and a fastening element including a fixing bolt having a length and two ends, a spacer element of a length with a cylindrical outside surface, and an elastomeric sleeve of a length where the fixing bolt is embraced by the cylindrical outside surface of the spacer element and the fixing bolt has a radially overhanging head with a larger outside diameter than the spacer element on one end and, on the other end, a fixing section that is adapted to interact with a counter element; wherein the elastomeric sleeve surrounds the spacer element and is longer than the spacer element, the elastomeric sleeve being positioned inside a bore of the assembly component so that the elastomeric sleeve is axially displaceable relative to the bore in the assembly component, as well as relative to the spacer element; and wherein the respective length of the elastomeric sleeve and the spacer element is longer than the height of the material region of the assembly component and the length of the fixing bolt is dimensioned such that the fixing section projects from the elastomeric sleeve.
- 2. The arrangement according to claim 1, wherein the spacer element is designed as a spacer sleeve through which the fixing bolt extends.
- 3. The arrangement according to claim 1, wherein the spacer element is a spacing cylinder that is formed onto the fixing bolt.
- 4. The arrangement according to claim 1, wherein the inside surface of the at least one bore and at least a central longitudinal section of the outside surface of the elastomeric sleeve are embodied as cylindrical shell surfaces.
- 5. The arrangement according to claim 1, wherein an end region of the elastomeric sleeve, which extends on either side of the bore of the assembly component, has a higher malleability than remaining regions of the elastomeric sleeve.
- 6. The arrangement according to claim 5, wherein the end region has a reduced wall thickness.
- 7. The arrangement according to claim 1, wherein the elastomeric sleeve is held in a friction-fit manner with the spacer element.
- 8. The arrangement according to claim 7, wherein the spacer element is positioned in such a way inside the elastomeric sleeve as to form an axially effective form-fitting connection that can be severed repeatedly if an axial force is administered.
- 9. The arrangement according to claim 7, further comprising a protective cap that is secured in axial direction on the fixing section of the fixing bolt, said protective cap having an outside diameter, which exceeds the inside diameter of the elastomeric sleeve.
- 10. The arrangement according to claim 2, wherein the spacer sleeve is held in a form-fitting manner on the fixing bolt.
- 11. The arrangement according to claim 10, wherein the fixing bolt has a radial ring-shaped projection that extends over the circumferential surface of the fixing bolt and the spacer sleeve has several projections, distributed over the circumference of the spacer sleeve, provided on the end of the spacer sleeve, near the head, where the projections of the spacer sleeve radially extend over the radial ring-shaped projection of the fixing bolt.
- 12. The arrangement according to claim 11, wherein the distance between the radial ring-shaped projection and the head is dimensioned such that the fixing bolt can move axially inside the spacer sleeve.
- 13. The arrangement according to claim 2, wherein the fixing bolt is positioned with radial play inside the spacer sleeve.
- 14. The arrangement according to claim 1, wherein at least one of the inside and the outside surface of the elastomeric sleeve is provided with a coating to improve sliding between the elastomeric sleeve and the spacer element.
- 15. A fastening element for attaching an assembly component with variable spacing to an understructure, said fastening element comprising:
a fixing bolt having a head at one end, a fixing section at an end opposite the one end that is adapted to interact with a counter element, and a threaded section between the one end and the opposite end; a spacer element having a diameter and length, said spacer element surrounding the fixing bolt and having an outside surface, where the head of the fixing bolt is larger in diameter than the diameter of the spacer element; and an elastomeric sleeve of a length longer than the length of the spacer element, said elastomeric sleeve surrounding the outside surface of the spacer element and being axially displaceable relative to the spacer element, wherein the fixing bolt has a length so that the fixing section projects from the elastomeric sleeve, the combination of the elastomeric sleeve, spacer element and fixing bolt is adapted to be inserted into a bore of an assembly component that has a material region of a height surrounding the bore of the assembly component, and the respective length of the elastomeric sleeve and the spacer element is longer that the height of the material region of the assembly component.
- 16. The fastening element according to claim 15, further comprising a threaded part, which interacts with the threaded section of the fixing bolt wherein after the combination of the elastomeric sleeve, spacer element and fixing bolt is inserted into a bore of an assembly component and a bore of an understructure that is to be attached to an assembly component with a gap, the threaded part is tightened against the understructure causing the head of the fixing bolt to push down on the elastomeric sleeve thereby shortening the elastomeric sleeve and pushing elastomeric material into the gap and the head of the fixing bolt and a top of the material region surrounding the bore of the assembly component so that a radially projecting bulge of elastomeric material is formed on either side of the material region surrounding the bore of the assembly component.
- 17. The fastening element according to claim 16, wherein the elastomeric sleeve tightly secures the assembly component to the understructure with vibration damping and seals the bore of the assembly component.
- 18. The fastening element according to claim 16, wherein the fixing bolt has a radial ring-shaped projection that extends over the circumferential surface of the fixing bolt and the spacer sleeve has several projections, distributed over the circumference of the spacer sleeve, provided on the end of the spacer sleeve, near the head, where the projections of the spacer sleeve radially extend over the radial ring-shaped projection of the fixing bolt.
- 19. The fastening element according to claim 16, wherein an end region of the elastomeric sleeve, which extends on either side of the bore of the assembly component, has a higher malleability than remaining regions of the elastomeric sleeve.
- 20. The arrangement according to claim 19, wherein the end region has a reduced wall thickness.
