Abstract

The wind deflector is used for reducing the air resistance of motor vehicle drawn trailers. It reduces resistance on towing trailers whose shape projects beyond the outline of the motor vehicle. This profile can project above the motor vehicle in the case of a caravan. Reduction of the air resistance improves the vehicle traction performance and reduces vehicle war. The deflector is mounted on the traction vehicle and slopes backwards. This deflects the air flow over the upper edge of the caravan. The wind deflector held on the traction vehicle rood is provided with an arrangement for adjusting the deflector angle. This adjusting angle can be adjusted by a servo arrangement by remote control from the driving position during traveling.

Description

Patentbeschreibung Windabweiser zur Reduzierung des Luftwiderstandes von Kfz.-AnhXngern, deren Profil leber den IJmriß des Psw wesentlich hinausragt. Patent description Wind deflector to reduce air resistance of motor vehicle fans, whose profile clearly protrudes beyond the outline of the Psw.

Beim Ziehen eines Kfz-Anhängers, dessen Profil insbesondere nach oben wesentlich über das Profil des Zugfahrzeuges hinausragt, (z.B. PKw mit Wohnwagen) tritt durch den erhöhten Luftwiderstand eine erheblich Mehrbel-stung des Zugfahrzeuges auf. Die Mehrbelastung äussert sich durch erheblich erhöhten Treibstoffverbrauch, durch höheren Verschleiß der Reifen der Antriebsräder, durch höheren Verschleiß an Motor, Getriebe, Differential und Antriebsachsen.When pulling a car trailer, its profile especially upwards protrudes significantly beyond the profile of the towing vehicle (e.g. car with caravan) the increased air resistance causes a considerable increase in the load on the towing vehicle on. The additional burden manifests itself in the significantly increased fuel consumption, through higher wear of the tires of the drive wheels, through higher wear on the engine, gearbox, differential and drive axles.

Ausserdem wird das Fahrverhalten insbesondere bei Fahrzeugen mit relativ schwachwer Antriebeleistung, dadurch dass sie an der Leistungs grenze gefahren werden müssen, stark eingeschränkt, Diese Fahrzeuge haben sowohl am erg als auch in kritischen Situationen keine Sicherheitsreserve mehr.In addition, the driving behavior is relative, especially in vehicles weak drive power, because they are driven at the performance limit must, severely restricted, these vehicles have both erg and critical Situations no longer have a safety reserve.

Gegenstand der Erfindung ist eine Windleiteinrichtung, die in Form eines schräg nach hinten angestellten Beitfliigels vorzugsweise auf dem Dach des 7ugwagens montiert wird und den Fahrwind huber die Oberkante des Anhängers ableitet. Dadurch wird der liuftwiderstand des Anhangers ganz erheblich reduziert. Der Stand der Technik wurde anhand folgender Patentschrift ermittelt: DP Nr. 1 630 241. Weitere Pantente konnten in dieser Klasse nicht ermittelt werten.The invention relates to a wind deflector in the form of a post slanting backwards, preferably on the roof of the 7ugwagens is mounted and the driving wind is diverted over the upper edge of the trailer. This considerably reduces the drag of the trailer. The stand the technology was determined on the basis of the following patent specification: DP No. 1 630 241. Others Pantents could not score in this class.
