Description
Die Erfindung betrifft eine Hebe- und Abatützvorrichtung für luftbereifte, infolge Entweichens, der Luft schadhaft gewordene Kraftfahrzeugräder mit einem neben dem Fahrz@eügreifen angeordneten,' heb- und senkbaren Hilfsrad. Die bekannten Vorrichtungen dieser Art werden vom Führersitz oder einer anderen Stelle des Fahrzeuges aus von Hand betätigt. Die Erfahrung hat gezeigt, daß es bei plötzlichem Entleeren des Luftreifens, beispielsweise beim Platzen eines Schlauches, nicht möglich ist, die Hebe- und Abstützvorrichtung so schnell in die Wirklage zu bringen, daß erhebliche Schäden am Reifen und Unglücksfälle wirksam vermieden werden können. . .The invention relates to a lifting and Abatützvorrichtung for pneumatic tires, as a result of escaping, the air damaged motor vehicle wheels with one beside the vehicle tire arranged, 'raisable and lowerable auxiliary wheel. The known devices of this type are from the driver's seat or another part of the vehicle from Hand operated. Experience has shown that if the tire is suddenly deflated, for example when a hose bursts, the lifting and supporting device is not possible to bring into action so quickly that significant tire damage and accidents can be effectively avoided. . .
Die Erfindung, die auf diesem Gebiet einen beträchtlichen Fortschritt bringt, besteht darin, daß das normalerweise in geringem Abstand- von der Fahrbahn angeordnete Hilfsrad oder dessen Achse durch eine biegsame Welle, eine Spindel, durch Räder od. dgl. mit den Steuerorganen des heb- und . senkbaren Hilfsradträgers gekuppelt ist, so daß beim Nachlassen des Luftdrucks im Reifen- und bei der dadurch bewirkten Senkung der-Laufradächse das Hilfsrad auf der Fahrbahn abrollt und das dä-` durch auf die Steuerorgane des Hilf sradträgers ausgeübte Drehmoment zwangsläufig ein Ausfahrendes Hilfsradträgers nach unten so lange bewirkt, bis der -schadhafte Reifen die Fahrbahn nichtmehr berühTt und demzufolge kein weiterer Verschleiß des Reifenmaterials stattfinden kann. Als Träger für das. Hilfsrad können .an sich bekannte, mechanisch, pneumatisch oder-hydraulisch betätigte' Wagenlieber Verwendung finden.The invention made a considerable advance in this field brings, is that it is usually at a short distance from the road arranged auxiliary wheel or its axis by a flexible shaft, a spindle, by wheels or the like. With the controls of the lifting and. lowerable auxiliary wheel carrier is coupled so that when the air pressure is released in the tire and in the thereby caused lowering of the wheel axles the auxiliary wheel rolls on the roadway and that dä-`inevitably due to the torque exerted on the control elements of the auxiliary wheel carrier a downward extension of the auxiliary wheel carrier until the defective Tire no longer touches the road and consequently no further wear of the Tire material can take place. As a carrier for the. Auxiliary wheel. Per se known, mechanically, pneumatically or hydraulically operated 'Wagenlieber use.
In der Zeichnung ist der Erfindungsgegenstand an einem Ausführungsbeispiel schematisch veranschaulicht. Es zeigt Fig. z eine Ansicht gegen die Innenseite der. Hebe- und Abstützvorrichtung und Fig. 2 eine Vorder- bzw. Rückansicht.In the drawing, the subject matter of the invention is based on an exemplary embodiment illustrated schematically. It shows Fig. Z a view against the inside of the. Lifting and supporting device and FIG. 2 a front and rear view.
Auf der Achse a des Kraftfahrzeuges ist neben dem Laufrad b das Gehäuse c eines Wagenhebers befestigt, dessen nach unten ausfahrbarer Teil d eine Gab-elf trägt, :in-Hilfsrad g drehbar gelagert ist. Dieses Hilfsrad wird so angeordnet, daß es im normalen Betriebszustand einen gewissen '--Ab"stärid@vöri"der Fahrbahn hat und mit dieser nur darin in lä#@rührung kommt, wenn die Laufradachse infolge stark verminderten Luftdr ückes im Reifen des Laufrades b nach unten absinkt. Das Laufrad bzw. dessen Achse ist mit einer biegsamen Welle h verbunden, welche zu den nicht dargestellten, im Gehäuse c des Hebers angeordneten Steuerorganen führt. Sobald das Hilfsrad während der Fahrt die Fahrbahn berührt und somit in Umdrehung versetzt wird, tritt der Heberrnechanismus in-Tätigkeit, d. h. der Teil d mit dem Hilfsrad wird nach unten: ausgefahren, und zwar soweit, bis der schadhafte Reifen den Boden nicht mehr berührt.On the axis a of the motor vehicle is next to the impeller b, the housing c of a jack, whose downwardly extendable part d a fork eleven carries: in-auxiliary wheel g is rotatably mounted. This auxiliary wheel is arranged so that in the normal operating state there is a certain '--Ab "strengid @ vöri" of the roadway has and only comes into contact with this when the impeller axis as a result greatly reduced air pressure in the tire of the impeller b drops downwards. That The impeller or its axis is connected to a flexible shaft h which leads to the not shown, arranged in the housing c of the lifter controls leads. As soon the auxiliary wheel touches the roadway while driving and thus sets it in rotation the lifting mechanism comes into operation, i. H. the part d with the auxiliary wheel is down: extended until the damaged tire hits the ground no longer touched.
