Abstract
A vehicle pressure vessel and manufacturing method which uses a vessel main part, an arched base, an arched cover, and one or more cross-webs connecting opposite walls of the vessel main part. The vessel main part is open at its top and bottom over which the cover and base respectively fit to close the vessel main part in a pressure-tight manner. A groove is embossed in the cross-webs where they connect to the opposite walls of the vessel main part. The cover and base each have an attachment rim that fits into the grooves when the cover and base are connected to the vessel main part.
Claims15
A method for producing a pressure vessel, comprising the steps:
- a) providing a vessel main part, which has a wall, a first opening at a first end, a second opening at a second end and at least one cross-web, which connects opposite wall segments of the wall of the vessel main part to one another,
- b) providing an arched cover and an arched base, wherein the arched cover has a cover attachment rim and the arched base has a base attachment rim,
- c) embossing, without cutting, a first and a second groove into the at least one cross-web at the first opening and introducing a third and fourth groove into the at least one cross-web at the second opening, wherein the grooves are embossed in respective regions of connection of the at least one cross-web to the opposite wall segments of the vessel main part,
- d) inserting the cover attachment rim into the grooves at the first opening and inserting the base attachment rim into the grooves at the second opening,
- e) securing the cover and the base on the vessel main part in the region of the first and second ends in order to close the vessel main part in a pressure-tight manner.
A pressure vessel for receiving and storing a medium under overpressure, comprising
- a vessel main part having a wall and at least one cross-web connecting opposite wall segments of the wall to one another, and further comprising a first opening and a second opening,
- an arched cover closing the vessel main part at the first opening and having a cover attachment rim,
- an arched base closing the vessel main part at the second opening and having a base attachment rim,
- a first and a second groove in the at least one cross-web at the first opening in the vessel main part, the cover attachment rim being received in the first and second grooves,
- a third and a fourth groove in the at least one cross-web at the second opening in the vessel main part, the base attachment rim being received in the third and fourth grooves,
- the grooves being embossed, without cutting, in respective regions of connection of the at least one cross-web to the opposite wall segments.
