Abstract

A working fluid unit, comprising a container having a temperature-sensitive vehicle working fluid contained therein, in particular for exhaust gas after-treatment, a container mantle which is open at least on one side and in which the vehicle working fluid is introduced and the opening of which is closed by a container lid, wherein the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding, or magnetic pulse crimping, wherein the connecting seam is spaced a distance from the vehicle working fluid that is present.

Claims

1. An operating fluid unit, comprising a container with a temperature-sensitive vehicle operating fluid contained therein, a container mantle open at least on one side, into which the vehicle operating fluid is introduced, and the opening of which is closed by means of a container lid, wherein the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding or magnetic pulse crimping, thereby forming a connecting seam.

2. The operating fluid unit according to claim 1, wherein the connecting seam is spaced a distance from the contained vehicle operating fluid.

3. The operating fluid unit according to claim 1, wherein the container lid is connected to the container mantle by magnetic pulse crimping with the interposition of a gasket ring into a groove of the container mantle and/or container lid.

4. The operating fluid unit according to claim 1, wherein the connecting seam is disposed with a distance from the interior of the container at an edge of the container lid facing outwards from the container opening.

5. The operating fluid unit according to claim 4, wherein the edge is profiled on the external peripheral side, preferably tapered.

6. The operating fluid unit according to claim 4, wherein the container lid is manufactured from sheet metal and the edge is manufactured by reshaping or beading.

7. The operating fluid unit according to claim 4, wherein the container lid is manufactured from cast synthetic material or cast metal, and the edge is manufactured by moulding.

8. A method for manufacturing a container containing a temperature-sensitive vehicle operating fluid, comprising the steps of:

providing a container mantle open on at least one side;

introducing the vehicle operating fluid into the container mantle; and

, closing the container mantle opening by means of a container lid, wherein the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding or magnetic pulse crimping, thereby forming a connecting seam.

9. The method according to claim 8, wherein the connecting seam is spaced a distance from the vehicle operating fluid.

10. The method according to claim 8, wherein the container lid is connected to the container mantle by magnetic pulse crimping with the interposition of a gasket ring into a groove of the container mantle and/or container lid.

11. The method according to claim 8, wherein the connecting seam is disposed at an edge of the container lid facing outwards away from the container opening.

12. The method according to claim 11, wherein the edge is embodied in a profiled manner on the external peripheral side, preferably in a tapered manner.

13. The method according to claim 11, wherein the container lid is manufactured from sheet metal, and the edge is manufactured by reshaping or beading.

14. The method according to claim 11, wherein the container lid is manufactured from cast synthetic material or cast metal, and the edge is manufactured by moulding or milling.
