Hollow chamber profile for a body structure of a rail vehicle and rail vehicle

摘要

The present invention relates to a hollow chamber profile (1) for a vehicle body structure (2) of a rail vehicle (3) having a first profile chamber (4) extending transversely to the longitudinal direction (X) and extending in a longitudinal direction (X) of the hollow chamber profile (1) at least one second profile chamber (5a, 5b) which extends in the longitudinal direction (X) of the hollow chamber profile (1) and is transverse to the longitudinal direction (X), the at least one second profile chamber (5a, 5b) being closed transversely to the longitudinal direction (X) Extrusion profile (7, 7 ') is formed. In order to ensure long-term high stability of the body structure (2), the invention proposes that, in a section transverse to the longitudinal direction (X), the cross-sectional area of the first profile chamber (4) is greater than the cross-sectional area of the at least one second profile chamber (5a , 5b). Furthermore, the invention relates to a rail vehicle (3) with a car body structure (2), which has at least one such hollow chamber profile (1) as a supporting component.
