AIR CONDUCTION ELEMENT FOR REDUCING AIR RESISTANCE OF A LOAD-CARRYING VEHICLE

摘要

The invention relates to an air conduction element (4) for reducing the air resistance of a load-carrying vehicle (1) having a load space structure (2). Said air conduction element can be externally mounted in the rear region (3) of the load space structure (2) and comprises an air conduction duct (5) with a front air inlet opening (6) and a rear air outlet opening (7), front and rear being in relation to the direction of travel (x). The air inlet opening (6) overlaps the load space structure (2) in the direction of travel (x) and the air outlet opening (7) is arranged behind the load space structure (2) within the cross-sectional contour thereof. The air conduction element (4) comprises a cover (8) which delimits the air conduction duct (5) and which is arranged movalby relative to the load space structure (2). Said cap slowly drops in the direction of the load space structure (2) when the air speed drops below a defined value and is raised by the air current in relation to the load space structure (2) when the air speed exceeds a defined value. It is therefore the aim of the invention to devise an air conduction element with which the maximum vehicle dimensions defined for the travel position of the air conduction element are maintained also during adjustment thereof. For this purpose, the cover (8) is mounted in relation to the load space structure (2) such that it can carry out a translatory movement only.
