Device for disturbing the air flow circulating beneath the chassis of a railway vehicle

摘要

The car (1) has a chassis (2) including a blocking device provided with a notch (20) formed in a vertical upstream wall (14). The notch is extended along a longitudinal direction, and traverses a lower edge (22) of the upstream wall. The notch is extended from a horizontal lower surface (4) forming a corner with the lower edge of the upstream wall. The notch is emerged from the upstream wall so as to avoid the continuity of sharp edge formed by the corner between the lower surface and the lower edge of the upstream wall.
