Body structure allowing the passage of fluid or gas under pressure and associated body
A bodywork structure for a body for a public transport vehicle, in particular a railway vehicle or a road transport vehicle, for example a guided road transport vehicle, including a wall extending in a longitudinal direction, the wall including at least one cavity extending in the longitudinal direction, wherein the cavity forms a passage for a fluid under pressure, for example a gas under pressure.
1. Bodywork structure for a body for a public transport vehicle, comprising a wall formed of one piece and extending in a longitudinal direction, the wall comprising:
at least one cavity extending in the longitudinal direction, the at least one cavity providing a passage for a fluid under pressure;
an inner face;
an outer face;
ribs connecting the inner face and the outer face, each cavity being defined between said inner face, said outer face and two adjacent ribs; and
at least one opening into the cavity, completely covered by a connecting plate that is welded to the wall, the connecting plate comprising an orifice.
2. Bodywork structure according to claim 1 , wherein said at least one cavity provides a passage for a gas under pressure.
3. Bodywork structure according to claim 1 , wherein the pressurized fluid has a pressure greater than 2×10 5 Pa (Pascal).
4. Bodywork structure according to claim 3 , wherein the pressure of the pressurized fluid is between 5×10 5 Pa and 10×10 5 Pa.
5. Bodywork structure according to claim 1 , said wall having a length in the longitudinal direction, and said at least one cavity extending over the entire length of said wall in the longitudinal direction.
6. Bodywork structure according to claim 5 , wherein said at least one cavity has a constant profile over the entire length of said wall in the longitudinal direction.
7. Bodywork structure according to claim 1 , wherein said wall comprises a plurality of cavities, at least one group of said cavities being a fluid or compressed gas reservoir.
8. Bodywork structure according to claim 1 , comprising a plurality of cavities, each cavity being insulated from each other cavity.
9. Body for a railway vehicle or guided road transport vehicle, comprising a bodywork structure according to claim 1 , said at least one cavity comprising a fluid or a gas under pressure, while said wall at least partially defines a vehicle interior of the body.
10. Body according to claim 9 , wherein said at least one cavity is provided at one end with at least one connecting element and/or at least one distribution element and/or at least one end plug.
11. Bodywork structure according to claim 1 , wherein the orifice is connected to a duct to allow passage of fluid or gas from the cavity to the duct, or vice versa.
12. Bodywork structure according to claim 1 , wherein the connecting plate comprises a valve for controlling the quantity of fluid or gas passing through the orifice.
