Description

Den Gegenstand der Erfindung bildet ein hydraulischer Heber für Kraftfahrzeuge.The subject of the invention is a hydraulic jack for motor vehicles.

Bisher kennt man Heber für Kraftfahrzeuge, die hei der Montage von Reifen od.,dgl. unter das Fahrzeug gesetzt werden. Von Hand wird dann eine Spindel über Schneckentrieb ausgefahren und hebt das Fahrzeug. Derartige Wagenheber können im Fahrzeug mitgeführt werden. In Werkstätten verwendet man kräftigere Wagenheber, die nach dem System eines Hubwagens mechanisch oder hydraulisch arbeiten.So far we know jacks for motor vehicles, the hot assembly of Tires or the like placed under the vehicle. A spindle is then made by hand Extended via worm drive and lifts the vehicle. Such jacks can be carried in the vehicle. More powerful jacks are used in workshops, which work mechanically or hydraulically according to the system of a lift truck.

Die aufgeführten Wagenheber haben den Nachteil, daB sie schwierig anzusetzen sind bzw.,der Ansohaffungspreis sehr hoch liegt.The listed jacks have the disadvantage that they are difficult are to be set or, the initial purchase price is very high.

Demgegenüber befaßt sich die Erfindung mit einem hydraulischen Wagenheber, bei dem vier hydraulische Zylinder am Fahrgestell angeordnet sind, deren Kolben durch Einpumpen einer Flüssigkeit nach unten ausfahren, wobei der Wagen gehoben wird. Wird die Flüssigkeit abgelassen, dann ziehen Federn die Kolben wieder in die Ausgangsstellung zurück. Die Zylinder sind in Radnähe am Fahrgestell ,des Kraftfahrzeuges befestigt, und die Flüssigkeit kann von einer h.and- oder motorenbetriebenen Pumpe über einen Mehrwegehahn wahlweise einem oder mehreren Zylindern zugeleitet werden.In contrast, the invention is concerned with a hydraulic jack, in which four hydraulic cylinders are arranged on the chassis, their pistons extend downwards by pumping in a liquid, with the carriage being lifted will. When the liquid is drained, the springs pull the pistons back into the Starting position back. The cylinders are close to the wheels on the chassis of the motor vehicle attached, and the liquid can be drawn from a hand-operated or motor-operated pump can optionally be fed to one or more cylinders via a multi-way valve.

Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung und der Beschreibung. In der Zeichnung ist der Gegenstand der r-rfindung beispielsweise dargestellt, und zwar zeigt Abb. i eine Seitenansicht eines Fahrgestelles mit zwei im Schnitt dargestellten Wagenhebern, wobei der eire Kolben in eingefahrener und der andere Kolben in ausgefahrener Stellung dargestellt ist, Abb. 2 eine Draufsicht.Further details of the invention emerge from the drawing and the description. In the drawing, the subject of the invention is for example shown, namely Fig. i shows a side view of a chassis with two jacks shown in section, the eire piston in retracted and the other piston is shown in the extended position, Fig. 2 is a plan view.

Vier hydraulische Zylinder b sind durch Rohrleitungen mit der Pumpe d verbunden, die von Hand oder durch einen Motor angetrieben wird. In den Zylindern b sind die Kolben a geführt, die beim Rücklauf der Druckflüssigkeit in die Öl- behälter der Pumpe d durch die Federn c in ihre ursprüngliche Lage zurückgezogen werden. Das Fahrgestell ist mit e bezeichnet.Four hydraulic cylinders b are connected by piping to the pump d, which is driven by hand or by a motor. The pistons a are guided in the cylinders b and are pulled back into their original position by the springs c when the pressure fluid flows back into the oil container of the pump d. The chassis is denoted by e.
