摘要

The vehicle (10) has a wheel (12) equipped with a tire (14) to realize a mechanical connection of the vehicle with a roadway on which the vehicle is evolved. A guiding unit (18) guides the gas flow in direction of a boundary (24) of a contact zone (22) of the wheel, where the contact zone is oriented in the normal forward direction (F1) of the vehicle. The guiding unit has a pipe forming a venturi to accelerate the gas flow. The pipe is debouched on an end face of the vehicle.
