Abstract

A damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, including, two identically constructed damping elements. Each damping element includes: a head portion with a first outer diameter, a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as a central first thru-opening, and only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element by means of a frictional and/or material connection. By means of the only one sleeve, the two identically constructed damping elements with bottom sides, facing each other, of the head portion with the first component arranged in between are fastenable to one another.

First claim

The invention claimed is:

1. A damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, the damping arrangement consisting of:
a. two identically constructed damping elements, each damping element consisting of an elastomer or a thermoplastic elastomer formed with:
a1. a head portion with a first outer diameter,
a2. a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as
a3. a central first thru-opening comprising a radially inwardly projecting projection adjacent to an upper side of the head portion, and

b. only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element by means of a frictional and/or material connection, wherein the only one sleeve has an axial length which is larger than the axial length of one damping element but smaller than the axial length of two damping elements so that
c. by means of the only one sleeve, the two damping elements with the first component arranged in between are fastenable to one another, wherein
c1. the bottom side of the head portions of the two damping elements face each other and
c2. the bottom sides of the head portions of the two damping elements abut at the first component, and
c3. the sides of the shaft portions of the two damping elements which face away from the head of the respective damping element abut each other.

2. The damping arrangement according to claim 1 , in which in the head portion, each damping element includes a projection at the radial outside extending parallel to the shaft portion.

3. The damping arrangement according to claim 2 , in which between the shaft portion and the projection, a plurality of ribs is provided at the bottom side of the head portion.

4. The damping arrangement according to claim 1 , in which a plurality of first and/or second breakthroughs is provided in the head portion of the damping element.

5. The damping arrangement according to claim 1 , in which each damping element includes a plurality of radially inwardly projecting projections in the central first thru-opening, which realize the frictional connection to the only one sleeve.

6. The damping arrangement according to claim 1 , wherein each damping element has a shore A hardness between 40 and 80 shore A.

7. The damping arrangement according to claim 1 , in which the only one sleeve includes a plurality of breakthroughs.

8. A first component with a component opening and with the damping arrangement according to claim 1 being arranged at least partly in the component opening of the first component.

9. A component connection comprising the first component according to claim 8 as well as a second component with a second opening and a connecting element, wherein the connecting element extends through the damping arrangement and engages with a fitting fastening portion in or adjacent to the second component.

10. The component connection according to claim 9 , wherein a radial tolerance compensation is realizable in that the only one sleeve has an inner diameter which is larger than the outer diameter of the connecting element.

11. The component connection according to claim 10 , in which the connecting element includes a head and a shaft and a disc is provided between the head of the connecting element and the damping element of the damping arrangement which is arranged adjacent to the head of the connecting element, wherein an outer diameter of the disc is larger than an inner diameter of the opening in the first component.

12. The component connection according to claim 9 , in which the connecting element includes a head and a shaft and a disc is provided between the head of the connecting element and the damping element of the damping arrangement which is arranged adjacent to the head of the connecting element, wherein an outer diameter of the disc is larger than an inner diameter of the opening in the first component.

13. A manufacturing method for a damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, the damping arrangement consisting of:
a. two identically constructed damping elements, each damping element consisting of an elastomer or a thermoplastic elastomer formed with:
a1. a head portion with a first outer diameter,
a2. a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as
a3. a central first thru-opening comprising a radially inwardly projecting projection adjacent to an upper side of the head portion, and

b. only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element b y means of a frictional and/or material connection, wherein the only one sleeve has an axial length which is larger than the axial length of one damping element but smaller than the axial length of two damping elements so that
c. by means of the only one sleeve, the two damping elements with the first component arranged in between are fastenable to one another, wherein
c1. the bottom side of the head portions of the two damping elements face each other and
c2. the bottom sides of the head portions of the two damping elements abut at the first component, and
c3. the sides of the shaft portions of the two damping elements which face away from the head of the respective damping element abut each other, the method including the steps:

a. providing the two damping elements,
b. providing the only one sleeve,
c. arranging the only one sleeve in one of the two damping elements first and after that in the remaining damping element, so that the two damping elements with a first component arranged in between, are fastenable at each other by means of the only one sleeve.

14. The manufacturing method according to claim 13 , in which the only one sleeve consists of a metal or a thermoplastic.

15. The manufacturing method according to claim 13 , in which the only one sleeve is made of an electrically conductive material.

16. The manufacturing method according to claim 13 , wherein the providing of one of the two damping elements takes place by overmolding the only one sleeve with a material of the damping element with a shore A hardness between 40 and 80 shore A.
