Zusammenfassung: | The utility model relates to a rail vehicle aluminum alloy automobile body boundary beam, including hollow boundary beam truss the interior plate of boundary beam truss bottom is provided with the spout that is used for hanging equipment under the car, the boundary beam truss with the spout forms the integral type structure through extrusion technology. The utility model discloses boundary beam truss and spout adopt integrative extrusion structure, wholly do not have the welding seam, have promoted the anti fatigue strength of boundary beam by a wide margin, and the integral type boundary beam has promoted the stiffness and mechanical strength, can reach the operation requirement of the improper operating mode load of bearing of european norm requirement, and simultaneously, load can balancedly distribute to the boundary beam. |
