Description
Vorrichtung zur Verbesserung des Fahrbahnkontaktes von Rädern an Kraftfahrzeugen bei nasser Fahrbahn Die Erfindung bezieht sicli auf eine Vorrichtung zur Verbesserung des Fahrbahnkontaktes von Rädern an Kraftfahrzeugen, insbesondere an sclmellen Personenkraftwagen, bei nasser Fahrbahn. Device to improve road contact of wheels Motor vehicles on wet roads The invention relates to a device to improve the road contact of wheels on motor vehicles, in particular on small passenger cars, on wet roads.
bei hohen Fahrgeschwindigkeiten können die Räder von Kraftfahrzeu-en auf nassen Fahrbahnen den Kontakt mit der Fahrbahn verlieren, weil sich Wasser wie ein Keil unter die Häder schiebt.At high driving speeds, the wheels of motor vehicles can lose contact with the road surface on wet roads because water like pushes a wedge under the hats.
Da sich aus diesem Effekt Unfälle mit meist schwerwiegenden Folgen ergeben, maciit es sich die rfindung zur Aufgabe, die Nässe auf der Fahrbahn vorübergehend in einem solchen Maße zu entfernen, daX die Bereifung der Bäder den verbleibenden Rest an Nässe wegdrücken kann, ohne den Fahrbahnkontakt zu verlieren.Since this effect leads to accidents with mostly serious consequences As a result, the task of finding a solution is to temporarily reduce the wetness on the roadway to be removed to such an extent that the frosting of the baths takes the remaining Can push away any remaining moisture without losing contact with the road.
Die gestellte Auf'gabe wird erfindungsgemäß dadurch gelöst, daß eine Blasvorrichtung vorgesehen ist, mit der ein vor jedem Rad ouer nur Jedem vorderen Rad die Nässe aut der Fahrbahn wegblasen der, aus Luft und gegebenenfalls aus Abgasen bestehenuer Gasstrom erzeugt wird.The task set is achieved according to the invention in that a Blower is provided with the one in front of each wheel or only each front Blow away the moisture from the road, from air and possibly from exhaust gases existing gas flow is generated.
Durch die Erfindung wird erreicht, daß die Räder auf höchstens feuchter Fahrbahn abrollen und den Fahrbahnkontakt nicht verlieren Das Profil der bereifung an den Rädern braucht niciit mehr aul eine nasse, sondern nur noch auf eine trockene una feuchte Fahrbahn ausgelegt zu werden. Dadurch werden günstige Fahrbedingungen f'ür Brems- und Beschleunigungsvorgänge und für Kurvenfahrt schaffen. Die Reiten können breiter gemacht werden, so dai3 auger der Haftung auf der Fahrbahn auch die Lebensdauer der Reifen, der Fahrkomfort und die Tragfähigkeit verbessert werden. Schlieblich wird noch erreicht, daß lockerer Schnee, Blätter, Nägel, Steine und dergleichen Gegenstände aus dem Weg der Räder weggeblasen werden.The invention achieves that the wheels are at most damp Roll off the road and do not lose contact with the road. The profile of the tires on the wheels nothing more is needed a wet one, but only to be laid out on a dry and damp road surface. This will be cheap Create driving conditions for braking and acceleration processes and for cornering. The rides can be made wider so that there is less grip on the road also improves tire life, driving comfort and load capacity will. Finally it is achieved that loose snow, leaves, nails, stones and similar objects are blown out of the way of the wheels.
In vorteilhafter Ausgestaltung oes Gegenstandes der E@fin@ung kann ein von dem Motor oder vom Triebwerk aes Kraftfahrzeuges, z.B. von der Gelenkwelle, angetriebener Kompressor vorgesehen sein, der direkt oder gegebenenfalls über einen Vorratsbehälter unter Druck stehendes Gas zu blasdüsen vor den Rädern fördert.In an advantageous embodiment of the object that can be developed one from the engine or the power unit of a motor vehicle, e.g. from the cardan shaft, Driven compressor may be provided, which is directly or optionally via a Reservoir promotes pressurized gas to air nozzles in front of the wheels.
Da es bei geringeren Fahrgeschwindigkeiten er@ahrungsgemäß ungefährlich ist, auf sehr nassen Fahrbahnen zu fahren, können die Blasdüsen erst ab einer bestimmten Geschwindigkeit des Fahrzeuges betrieben werden, wobei die Ausbildung der Vorrichtung derart vorgenommen sein kann, daß die abgeblasene Gasmenge mit zunehmender Fahrgeschwindigkeit zunimmt.Since it is safe to use at lower driving speeds is to drive on very wet roads, the air nozzles can only be used from a certain point Speed of the vehicle can be operated, with the formation of the device can be made such that the amount of gas blown off with increasing driving speed increases.
Der Betrieb der Blasdüsen kann automatisch in Abhängigkeit von der Nässe der Fahrbahn erfolgen. Ferner kann vorgesehen sein, daX dem abgeblasenen Gas reibungserhöhende Stoffe, z.B. Sand, beigemengt werden.The operation of the air nozzles can be automatic depending on the Wetness of the road. It can also be provided that the vented gas friction-increasing substances, e.g. sand, can be added.
In der Zeichnung ist aer Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing aer is the subject of the invention in one embodiment shown.
bei dem gezeigten Kraftwagen 1 ist vor jedem Rad 2 an der Voruerachse und vor jedem Rad 2 an der Hinterachse je eine Blasdüse 3 angeordnet, deren Mündung gegen die Fahrbann 4 gericiltet ist.In the motor vehicle 1 shown, there is in front of each wheel 2 on the front axle and in front of each wheel 2 on the rear axle a blower nozzle 3 is arranged, the mouth of which against the Fahrbann 4 is gericiltet.
Diese Blasdüsen 3, die gegebenenfalls als Flachstrahldüsen ausgebildet sein können, haben die Aufgabe, bei schneller Fahrt auf nasser Fahrbahn die Nässe vor den Hädern 2 nach der Seite hin wegzublasen, damit die Räder ihren Kontakt mit der Fahrbahn nicht verlieren.These nozzles 3, which may be designed as flat jet nozzles can be, have the task of driving fast on a wet road the wet to blow away to the side in front of the wheels 2 so that the wheels make contact with them do not lose the road.
Die Blasdüsen 3 sind an ein Leitungssystem angeschlossen, in das gegebenenfalls unter Zwischensciialtung eines Vorratsbehälters, ein Kompressor oder Gebläse Luft fördert. Der Kompressor wird von dem Motor des Kraftwagens 1 angetrieben, wobei eine Inbetriebnahme des Kompressors zweckmäßigerweise nur dann erfolgt, wenn die Blasdüsen 3 in Funktion treten sollen.The blower nozzles 3 are connected to a line system into which, if necessary with an intermediate storage container, a compressor or a blower air promotes. The compressor is driven by the engine of the motor vehicle 1, wherein a commissioning of the compressor expediently only takes place when the Blowing nozzles 3 should come into operation.
