Air conduction element for reducing air resistance of a load-carrying vehicle

An air conduction element for reducing the air resistance of a load-carrying vehicle having a cargo space structure, which is externally mounted in the rear region of the cargo space structure and comprises an air conduction duct with a front air inlet opening and a rear air outlet opening in a direction of travel (x), wherein the air inlet opening overlaps the cargo space structure in the direction of travel (x) and the air outlet opening is arranged behind the cargo space structure within its cross section contour, wherein the air conduction element comprises a cover which delimits the air conduction duct and which is arranged movably relative to the cargo space structure, which drops when the air speed falls below a defined value in the direction of the cargo space structure and which is lifted upon exceeding the air speed of the air flow relative to the cargo space structure,

• wherein the cover is mounted in relation to the cargo space structure such that it can carry out only a translatory movement and not any rotational movement,
• wherein the cover is formed as an integral, rigid-shape hood, and
• wherein first side walls are arranged on the rigid-shape hood at the side oriented in the direction of the cargo space structure, and overlapping with second side walls protruding with respect to the cargo space structure.

• wherein the cover is held on the cargo space structure by articulated connection elements, and
• wherein the connection elements comprise at least one first and second joint, oriented relative to each other, whose bearing axes are arranged horizontally displaced by 90° relative to each other.
