Description
Es sind bereits Straßenfahrzeuge mit einem hydraulisch-mechanischen Antrieb bekannt, bei dem hand- oder fußbetätigte Kolben von Kraftpumpen über eine Druckflüssigkeit einen an der Achse des Treibrades sitzenden Drehkolbenmotor oder eine Turbine antreiben oder die Kolben von Arbeitspumpen bewegen und von diesen letzteren Kolben durch Zahnstangen mit Ritzeln das Fahrzeug antreiben.There are already road vehicles with a hydraulic-mechanical Drive known in which hand or foot operated pistons of power pumps via a Hydraulic fluid a rotary piston motor seated on the axis of the drive wheel or drive a turbine or move the pistons of and from working pumps the latter piston drive the vehicle through toothed racks with pinions.
Die Erfindung bezweckt, bei Fahrzeugen mit einem Antrieb der letztgenannten Art diesen so auszubilden, daß leicht .eine Veränderung der Übersetzung der ausgeübten Kraft durchzuführen ist, so daß der Fahrer je nach Beschaffenheit des Geländes beim Befahren von Ebenen und mehr oder weniger starken Steigungen in der Lage ist, durch mehr oder weniger schnelle Muskelbewegung sein Fahrzeug mit angemessener Geschwindigkeit fortzubewegen.The invention aims, in vehicles with a drive of the latter Art of training this in such a way that it is easy to change the translation of the one exercised Force is to be carried out, so that the driver depending on the nature of the terrain when Driving on plains and more or less steep inclines is able to get through more or less rapid muscle movement his vehicle at a reasonable speed move around.
Die Neuerung gemäß der Erfindung besteht darin, daß jeder von zwei Kraftpumpen mehrere Arbeitspumpen verschiedener Länge und verschiedenen Durchmessers zugeordnet sind, in deren Druckflüssigkeitszugängen sich einstellbare Drehschieber od. dgl. befinden, die je nach ihrer Einstellung die Druckflüssigkeit aus den Kraftpumpen in ein, zwei oder mehr der Arbeitspumpen einführen und in die ersteren zurückfließen lassen.The innovation according to the invention is that each of two Power pumps several working pumps of different lengths and different diameters are assigned, in the hydraulic fluid accesses adjustable rotary valve Od. The like. Depending on their setting, the hydraulic fluid from the power pumps introduce into one, two or more of the working pumps and flow back into the former permit.
In der Zeichnung ist ein Schema eines hydraulisch-mechanischen Fahrzeugantriebes mit hydraulischer Übersetzung gemäß der Erfindung dargestellt.The drawing shows a schematic of a hydraulic-mechanical vehicle drive shown with hydraulic translation according to the invention.
Für jeden Fuß bzw. jede Hand ist eine Kraftpumpe i vorgesehen. Die in deren Zylindern befindliche Druckflüssigkeit wird beim Abwärtshub der Kolben durch je eine Leitung zwei miteinander verbundenen und mittels eines Hebels verstellbaren Drehschiebern :2 zugeführt und strömt beim Aufwärtshub der Kolben in die Pumpenzylinder zu rück. Von den Drehschiebern gehen getrennte Leitungen zu den Zylindern von je drei Arbeitspumpen 3, die von verschiedenem Durchmesser und von verschiedener Länge sind. An den Kolben der Pumpen 3 sitzen Zahnstangen, die durch je ein Ritzel eine Welle q. in einer Richtung. in Drehung versetzen. Jedes Ritzel sitzt auf einem Freilauf, um eine Rückwärtsbewegung der Zahnstangen entgegen der Drehrichtung zu :ermöglichen. Auf der Welle q. ist das eine Rad eines Kettentriebes 5 befestigt, dessen anderes Rad auf der Achse des Fahrzeugtreibrades 6 sitzt.A power pump i is provided for each foot or hand. the The hydraulic fluid in their cylinders becomes the piston on the downward stroke two lines connected to each other and adjustable by means of a lever Rotary valves: 2 supplied and flows into the pump cylinders on the upstroke of the pistons return. Separate lines go from the rotary valves to the cylinders of each three working pumps 3 of different diameters and lengths are. On the pistons of the pumps 3 there are racks, each with a pinion Wave q. in one direction. set in rotation. Each pinion sits on a freewheel, to allow the racks to move backwards against the direction of rotation: enable. On the wave q. one wheel of a chain drive 5 is attached, the other one Wheel sits on the axis of the vehicle drive wheel 6.
Die gewünschte Übersetzung der Kraftübertragung wird durch Drehverstellung der Schieber a erreicht, wobei je nach der Einstellung die eingeschlossenen Flüssigkeitsmengen wahlweise in eine, zwei oder alle drei Arbeitspumpen 3 ein- und nach Arbeitsleistung aus diesen wieder in die Kraftpumpen i zurückgeführt werden.The desired translation of the power transmission is achieved through rotary adjustment the slide reaches a, depending on the setting, the amount of liquid enclosed optionally in one, two or all three working pumps 3 one and according to work performance from these are fed back into the power pumps i.
