Vibration damper for connecting two devices
The invention relates to a vibration damper for connecting two devices to one another, in particular an engine to an environment ( 100 ) of the engine, for example a car body, wherein the vibration damper includes a damping section ( 20 ) and a fastening section ( 10 ), wherein the mounting portion ( 10 ) is formed with first and second pipe socket portions ( 14 ) having a flange ( 12 ), and wherein the damping portion ( 20 ) at least partially surrounds the fastening portion ( 10 ) at the outer surface thereof.
1. A vibration damper for connecting two devices to one another, comprising:
a) a damping portion formed with first and second damping elements that each define partial circumferential wall portions,
b) a fastening portion defining an outer surface,
wherein the fastening portion is formed with first and second pipe socket portions, wherein each of the first and second pipe socket portions having a flange,
wherein the damping portion at least partially surrounds the fastening portion at the outer surface thereof, and
wherein the first and second damping elements have inner circumferential engagement structures on the partial circumferential wall portions which correspond to outer circumferential engagement geometries on the first and second pipe socket portions.
2. The vibration damper according to claim 1 , wherein the first and second damping elements are cylindrical and are formed with respective partial circumferential wall portions.
3. The vibration damper according to claim 2 , wherein the partial circumferential wall portions of the first and second damping elements are extended over equal angular ranges.
4. The vibration damper according to claim 3 , wherein the equal angular ranges extend from 85° to 90° in each case.
5. The vibration damper according to claim 4 , wherein the equal angular ranges are 90° in each case.
6. The vibration damper according to claim 1 , wherein the pipe socket portions include circumferential engagement geometries that connect the pipe socket portions to the first and second damping elements through engagement with the circumferential engagement structures.
7. The vibration damper according to claim 6 , wherein the circumferential engagement structures comprise one or more grooves.
8. The vibration damper according to claim 1 , wherein the damping portion is provided on its outside with a surface structure.
9. The vibration damper according to claim 8 , wherein the surface structure is selected from the group consisting of bulges or lips formed in the direction of the cylinder axis of the vibration damper.
10. The vibration damper according to claim 1 , wherein the first and second damping elements have flange-like structures at their ends on the front side in the installation position.
11. The vibration damper according to claim 10 , wherein the flange-like structures are formed with contact projections extending in the cylinder axis direction of the vibration damper.
12. The vibration damper according to claim 1 , wherein a the first and second flanged pipe socket portions are configured to receive a retaining portion axially therethrough.
13. The vibration damper according to claim 1 , wherein the first and second damping elements are cylindrical.
14. The vibration damper according to claim 1 , wherein the inner circumferential engagement structures correspond to a recess and the outer circumferential engagement geometries correspond to an extension, or vice versa.
15. The vibration damper according to claim 1 , wherein the pipe socket sections with flange and first and second damping elements are each formed as identical parts.
16. The vibration damper according to claim 1 , wherein the pipe socket portions abut one another with their pipe end sections in the installed position or leave a gap into which an elastic damping separating element can be inserted.
