Abstract
Description
Die Erfindung bezieht sich auf einen Windkanal-Prüfstand für Fahrzeuge mit einer Windkanalwaage, mindestens einer Antriebseinheit für Fahrzeugräder und mit der Fesselung und Abstützung des Fahrzeuges dienenden Stützeinheiten.The The invention relates to a wind tunnel test bench for Vehicles with a wind tunnel balance, at least one drive unit for vehicle wheels and with the bondage and support of the Vehicle supporting units.

Üblicherweise wird also bei einem Windkanalversuch mit Bodensimulation (Raddrehung u. s. w.) das Fahrzeug gemäß Stand der Technik mittels Schwellerstützen auf der Windkanalwaage fixiert und ist somit in alle Richtungen unbeweglich. Die Standhöhe des Fahrzeuges wird dann mechanisch über das Einstellen der Schwellerstützen bestimmt.Usually So is in a wind tunnel test with ground simulation (wheel rotation u. s. w.) The vehicle according to the prior art Fixed by means of sill supports on the wind tunnel scale and thus is immovable in all directions. The height of the stand of the vehicle is then mechanically over the setting the sill supports determined.
Von daher liegt der Erfindung die Aufgabe zugrunde, die Fesselung und Abstützung des Fahrzeuges im Prüfstand dergestalt auszubilden, dass eine größtmögliche Annäherung an die Gegebenheiten bei normaler Straßenfahrt erreichbar ist.From Therefore, the invention has the object, the bondage and Support of the vehicle in the test bench in such a way train that the greatest possible Approaching the conditions of normal road driving is reachable.
Die erfindungsgemäße Lösung ist in Patentanspruch 1 angegeben. Damit ist eine „natürliche” Bewegung des Fahrzeugs in Richtung normal zum Untergrund während eines Prüfstandsversuches gegeben. Abhängig von der Windlast (Auftrieb bzw. Abtrieb) und der Federsteifigkeit des Fahrwerks kann das Fahrzeug, wie dies auch bei der üblichen Straßenfahrt der Fall ist, die Standhöhe ausbalancieren. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen beansprucht.The inventive solution is in claim 1 indicated. This is a "natural" movement of the vehicle in the direction normal to the underground during a test bench trial given. Depending on the wind load (buoyancy or downforce) and the spring stiffness of the Suspension can be the vehicle, as is the case with the usual Road travel is the case, balance the standing height. Further advantageous embodiments and refinements of the invention are claimed in the subclaims.
