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 demoulded 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 ).

First claim

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 ).

2 . The axially damping elastomer bearing ( 11 ) according to claim 1 , 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 ).

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

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

5 . The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein the outer peripheral surface ( 35 ) of the peripheral wall ( 19 ) follows a continuous curve 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 3 , 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 ).

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

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

9 . The axially damping elastomer bearing ( 11 ) according to claim 1 , wherein the clearance is formed as a slot ( 65 ) extending from the base ( 22 ) and running through the peripheral wall ( 19 ).

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

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

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

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

14 . 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.

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

16 . The axially damping elastomer bearing ( 11 ) according to claim 8 wherein the drainage opening ( 33 ) is substantially square with rounded corners.

17 . The axially damping elastomer bearing ( 11 ) according to claim 10 , wherein the aluminium is die-cast aluminium.

18 . The axially damping elastomer bearing ( 11 ) according to claim 12 , wherein the injection-moulded plastic is fibre-reinforced injection-moulded plastic.
