Abstract

An air spring component includes at least two parts, which have corresponding joining areas. The joining areas are connected to one another in an adhesive-bonded manner in an inert atmosphere. The air spring component can be a rolling piston, a supplementary volume container for the rolling piston or an air spring pot.

Claims (28)

1. An air spring component, comprising:

a rolling piston;

a supplementary volume container for the rolling piston, the supplementary volume container including a top part having first joining areas and a bottom part having second joining areas; and

an adhesive bond connecting the first and second joining areas to one another;

wherein the joining areas are formed from at least one of corresponding edge sections, ribs, and webs of the parts.

2. The air spring component according to claim 1 , wherein at least one of the top part and the bottom part includes a weld seam covering, which covers a joint gap.

3. The air spring component according to claim 2 , wherein the weld seam covering protrudes from a first of the top part and the bottom part and rests in a corresponding recess on a second of the top part and the bottom part.

4. The air spring component according to claim 1 , wherein at least one of the ribs and the webs project radially inward or outward from a housing wall of the parts.

5. The air spring component according to claim 1 , wherein at least one of the webs and the ribs have an approximately T-shaped basic shape.

6. The air spring component according to claim 1 , wherein the joining areas include fusible projections.

7. An air spring component, comprising:

a bottom part;

a top part; and

a dividing wall arranged between the bottom part and the top part,

wherein the dividing wall connects corresponding joining areas of the bottom part and the top part in an adhesive-bonded manner to form a supplementary volume container, and

wherein the top part, the dividing wall, and the bottom part each has a passage that coincides with a passage in a rolling piston.

8. The air spring component according to claim 7 , wherein at least one of the rolling piston and the supplemental volume container includes a thermoplastic.

9. The air spring component according to claim 8 , wherein at least one of the rolling piston and the supplemental volume container includes a glass fiber reinforced thermoplastic.

10. The air spring component according to claim 7 , wherein the top part is connected by a second adhesive-bond to the rolling piston.

11. The air spring component according to claim 7 , wherein the supplementary volume container is connected to the rolling piston in at least one of an adhesive-bonded manner, a positive-locking manner, and a nonpositive-locking manner.

12. The air spring component according to claim 7 , wherein the dividing wall includes webs that correspond to ribs of at least one of the top part and the bottom part.

13. The air spring component according to claim 7 , further comprising a rolling piston.

14. A method for producing an air spring component, comprising:

providing a first part and a second part having corresponding joining areas;

connecting the corresponding joining areas of the first part and the second part to one another in an adhesive-bonded manner in an inert atmosphere via hot gas welding,

wherein a hot gas used during the hot gas welding forms the inert atmosphere.

15. The method for producing an air spring component according to claim 14 , further comprising heating the joining areas by infrared radiation, mirror heating, and/or induction.

16. The method for producing an air spring component according to claim 14 , wherein the hot gas is Nitrogen and wherein the inert atmosphere is the Nitrogen gas.
