. Bei den bekannten Flüssigkeits-Wechsel- und -Wendegetrieben mit Pumpen und Motoren kann die Geschwindigkeit gewöhnlich nur stufenweise verändert werden. Bei Anordnungen mit veränderlichem Hub kann zwar eine beliebige Geschwindigkeitsregelung stattfinden. Es verursachen jedoch die vielen kleinen Pumpenkolben mit geringem Hub große Verluste durch undichte Stopfbuchsen und durch die. In the known fluid change and reversing gearboxes with pumps and motors the speed can usually only be changed in stages. With orders with a variable stroke, any speed control can take place. However, the many small pump pistons with a small stroke cause large losses through leaky stuffing boxes and through the
ίο mit großer Geschwindigkeit hin und her geschleuderten Kolbenmassen. Auch durch die Leitung der Flüssigkeit durch Schieber und Rohrleitungen zu den Motoren entstehen Energieveiiuste. ίο flung back and forth at great speed Piston masses. Energy reserves also arise when the liquid is conveyed through valves and pipes to the motors.
Diese Nachteile sollen durch die nachstehend beschriebene Erfindung vermieden und neue, technische Vorteile erzielt werden.These disadvantages are to be avoided by the invention described below and new, technical advantages can be achieved.
Zu diesem Zwecke ist die in Fig. 1 im Querschnitt und in Fig. 2 im Längsschnitt dargestellte Flüssigkeitspumpe und der Flüssigkeitsmotor in einem Gehäuse i untergebracht, durch dessen feste Zwischenwände w einerseits der Pumpenkolben d, anderseits der Motorkolben e hindurchragt.For this purpose, the liquid pump shown in cross section in FIG. 1 and in longitudinal section in FIG. 2 and the liquid motor are accommodated in a housing i , through whose fixed partition walls the pump piston d on the one hand and the motor piston e on the other hand protrude.
Durch Verschieben der Kolben zugleich mit der mittleren Wand c, durch welche die Flüssigkeitspumpe p von dem Flüssigkeitsmotor m getrennt ist, wird die Leistung der Pumpe verringert oder vergrößert und gleichzeitig die Leistung des Flüssigkeitsmotors in demselben Maße vergrößert oder verringert. Zwischen dem Kolben d der Pumpe p und dem Kolben e des Flüssigkeitsmotors m befindet sich eine Mittelwand c, die nicht drehbar, aber seitlich mitverschiebbar ist. Wird die Druckfläche des Pumpenkolbens d durch Längsverschieben verkleinert, so wird gleichzeitig die Druckfläche des Flüssigkeitsmotorkolbens e vergrößert. Die Folge davon ist, daß sich der Kolben e des Flüssigkeitsmotors m langsamer dreht als der Pumpenkolben d und die Kraft vergrößert wird, ähnlich wie bei einer hydraulischen Presse, bei welcher durch einen kleinen Pumpenkolben, die Druckflüssigkeit' auf den großen Pressekolben geleitet wird. Wird dagegen die Druckfläche des Pumpenkolbens d durch Verschieben vergrößert und. dadurch gleichzeitig die Druckfläche des Flüssigkeitsmotorkolbens e verkleinert, so läuft die Kolbenwelle f des Flüssigkeitsmotors m schneller als die Kolbenwelle g der Pumpe p. Sind beide Druckflächen gleich groß, so laufen beide Kolbenwellen f und g gleich schnell.By moving the piston at the same time as the central wall c, by which the liquid pump p is separated from the liquid motor m , the output of the pump is reduced or increased and at the same time the output of the liquid motor is increased or decreased to the same extent. Between the piston d of the pump p and the piston e of the liquid motor m there is a central wall c, which cannot be rotated, but can be moved laterally with it. If the pressure area of the pump piston d is reduced by longitudinal displacement, the pressure area of the liquid motor piston e is increased at the same time. The consequence of this is that the piston e of the liquid motor m rotates more slowly than the pump piston d and the force is increased, similar to a hydraulic press, in which a small pump piston guides the pressure fluid onto the large press piston. If, on the other hand, the pressure surface of the pump piston d is increased by moving it and. thereby simultaneously reducing the pressure surface of the liquid motor piston e , the piston shaft f of the liquid motor m runs faster than the piston shaft g of the pump p. If both pressure surfaces are the same size, both piston shafts f and g run at the same speed.
Man'hat es also in der Hand, der Flüssigkeitsmotorkolbenwelle f durch Verschieben der KoI-ben jede gewünschte Geschwindigkeit zu geben, ohne daß Kraftverluste durch Bremsung oder Rückleitung der Druckflüssigkeit ohne Arbeitsverrichtung entstehen. Soll die Welle f des Flüssigkeitsmotors m eine andere Drehrichtung erhalten, so braucht nur durch einen Schieber oder Hahn h die Flüssigkeit auf die andere Seite des Kolbens geleitet zu werden. Wenn jedoch, wie dies bei Automobilmotoren-häufig vorkommt, die Kardanwelle direkt mit der Motorwelle 6g verbunden werden soll, ohne daß durch das Flüssigkeitsgetriebe Kraftverluste entstehen sollen, dann schließt man den Schieber oder Hahn h, so daß keine Flüssigkeit von der Pumpe p in den Flüssigkeitsmotor m gelangenSo it is up to you to give the liquid motor piston shaft f any desired speed by shifting the piston, without any loss of power due to braking or return of the hydraulic fluid without performing any work. If the shaft f of the liquid motor m is to have a different direction of rotation, the liquid only needs to be passed to the other side of the piston through a slide or cock h. If, however, as is often the case with automobile engines, the cardan shaft is to be connected directly to the motor shaft 6g without any loss of power due to the fluid transmission, then the slide or valve h is closed so that no fluid from the pump p into the Get liquid motor m
