Abstract

An axially damping elastomer bearing suitable for a motor vehicle, with a crucible-formed receptacle (13) for surrounding receiving an elastomeric support spring (15). The crucible-formed receptacle (13) is manufactured through casting and can be demolded in a demolding direction (39) and has a peripheral wall (19) with at least one drainage opening (33), wherein the at least one drainage opening (33) has a clearance (43, 45, 65) extending in the demolding direction (39).

First claim

The invention claimed is:

1. An axially damping elastomer bearing ( 11 ) with a crucible-formed receptacle ( 13 ) for surroundingly receiving an elastomeric support spring ( 15 ), wherein the crucible-formed receptacle ( 13 ) is manufactured through casting and is demoldable in a demoulding direction ( 39 ) and has a peripheral wall ( 19 ) with at least one drainage opening ( 33 ), wherein the at least one drainage opening ( 33 ) has a clearance ( 43 , 45 , 65 ) extending in the demoulding direction ( 39 ), wherein the clearance is formed by a first ( 43 ) and a second slot ( 45 ), and wherein the first ( 43 ) and the second slot ( 45 ) are formed in different peripheral surfaces ( 29 , 35 ) of the peripheral wall ( 19 ) and form a shared overlapping region ( 49 ).

2. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein the first slot ( 43 ) is formed in an outer peripheral surface ( 35 ) of the peripheral wall ( 19 ) in a region of an end facing a base ( 22 ) of the crucible-formed receptacle ( 13 ) and the second slot ( 45 ) is formed in an inner peripheral surface ( 29 ) of the peripheral wall ( 19 ) in the region of the end facing away from the base ( 22 ) of the crucible-formed receptacle ( 13 ).

3. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein an inner peripheral surface ( 29 ) of the peripheral wall ( 19 ) follows a continuous curve in a region of an end facing the base ( 22 ) of the crucible-formed receptacle ( 13 ).

4. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein an outer peripheral surface ( 35 ) of the peripheral wall ( 19 ) follows a continuous curve in a region of an end facing away from the base ( 22 ) of the crucible-formed receptacle ( 13 ).

5. The axially damping elastomer bearing ( 11 ) according to claim 2 , wherein the inner peripheral surface ( 29 ) of the peripheral wall ( 19 ) has a peripheral shoulder ( 25 ) for receiving a cover part ( 17 ) in the region of the end facing away from the base ( 22 ) of the crucible-formed receptacle ( 13 ).

6. The axially damping elastomer bearing ( 11 ) according to claim 5 , wherein a depth ( 51 ) of the peripheral shoulder ( 25 ) substantially corresponds to a depth ( 53 ) of the second slot ( 45 ).

7. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein the drainage opening ( 33 ) is substantially rectangular in cross section.

8. An axially damping elastomer bearing ( 11 ) with a crucible-formed receptacle ( 13 ) for surroundingly receiving an elastomeric support spring ( 15 ), wherein the crucible-formed receptacle ( 13 ) is manufactured through casting and is demoldable in a demoulding direction ( 39 ) and has a peripheral wall ( 19 ) with at least one drainage opening ( 33 ), wherein the at least one drainage opening ( 33 ) has a clearance ( 43 , 45 , 65 ) extending in the demoulding direction ( 39 ), wherein the clearance is formed as a slot ( 65 ) extending from a base ( 22 ) and running through the peripheral wall ( 19 ).

9. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein at least the crucible-formed receptacle ( 13 ) is made of aluminium.

10. The axially damping elastomer bearing ( 11 ) according to claim 9 , wherein the crucible-formed receptacle ( 13 ) and a cover part ( 17 ) are joined by roll beading.

11. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein at least the crucible-formed receptacle ( 13 ) is made of injection-moulded plastic.

12. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein the elastomer bearing ( 11 ) is designed as a dry elastomer bearing without damping fluid.

13. The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein the elastomer bearing ( 11 ) is designed as a hydro bearing with a damping fluid.

14. The axially damping elastomer bearing according to claim 1 , wherein the bearing is for a motor vehicle.

15. The axially damping elastomer bearing ( 11 ) according to claim 7 , wherein the drainage opening ( 33 ) is substantially square with rounded corners.

16. The axially damping elastomer bearing ( 11 ) according to claim 9 , wherein the aluminium is die-cast aluminium.

17. The axially damping elastomer bearing ( 11 ) according to claim 11 , wherein the injection-moulded plastic is fibre-reinforced injection-moulded plastic.
