Description

Regelungsvorrichtung für Flüssigkeitsgetriebe. Die Patentschrift 430 522 betrifft eine Regelungsvorrichtung für Flüssigkeitsgetriebe, bei der die Ein- und Auslässe der Pumpe und des Motors je in eine von vier Kammern eines Flüssigkeitsgehäuses münden, dessen Kammern durch einen einzigen Drehschieber paarweise miteinander zu verbinden sind.Control device for fluid transmissions. Patent 430 522 relates to a control device for fluid transmissions, in which the input and outlets of the pump and the motor each into one of four chambers of a liquid housing open out, the chambers of which are closed in pairs by a single rotary valve connect are.

Eingehende Versuche mit derartigen Vorrichtungen haben bei Verwendung von Flügelkolbenpumpen oder kreisenden Kolbenpumpen mit nicht verstellbarem Hub zu der Feststellung geführt, daß der hydraulische Wirkungsgrad der Vorrichtung beim Wechsel der Geschwindigkeiten nicht den Anforderungen der Praxis entspricht, da beim Wechsel der Geschwindigkeiten ein Drosseln der Flüssigkeit erfolgt, so daß erhebliche hydraulische Verluste entstehen.Thorough experiments with such devices have resulted in use of vane pumps or rotating piston pumps with non-adjustable stroke led to the finding that the hydraulic efficiency of the device at Changing the speeds does not meet the requirements in practice, since when changing the speeds a throttling of the liquid takes place, so that considerable hydraulic losses arise.

Dieser NTachteil wird behoben durch die Verwendung von an sich bekannten kreisenden Kolbenpumpen mit verstellbarem Hub als Flüssigkeitspumpe und Flügelkolbenpumpen oder ähnlich wirkenden kreisenden Kolbenpumpen mit oder ohne verstellbaren Hub als Flüssigkeitsmotor. Soll nun der Vorteil der im Patent 43o 522 dargestellten Regelungsvorrichtung nicht herabgemindert werden, so muß bei Verwendung von kreisenden Kolbenpumpen mit verstellbarem Hub die im Patent gekennzeichnete Regelungsvorrichtung mit der Regelungsvorrichtung der verstellbaren Kolbenpumpe derart verbunden werden, daß nur eine Bedienungsvorrichtung für beide Regelungsvorrichtungen erforderlich ist, d. h., die Verstellung der Regelungsvorrichtung des Flüssigkeitsgetriebes von Vorwärts auf Rückwärts und umgekehrt muß gleichzeitig mit der Verstellung des Kolbenhubes der kreisenden Kolbenpumpe vor sich gehen.This disadvantage is eliminated through the use of known ones rotary piston pumps with adjustable stroke as liquid pumps and vane pumps or similarly acting rotating piston pumps with or without an adjustable stroke as Liquid motor. Should now the advantage of the control device shown in patent 43o 522 not be reduced, so must when using rotating piston pumps with adjustable stroke the control device identified in the patent with the control device the adjustable piston pump are connected in such a way that only one operating device is required for both control devices, d. i.e., the adjustment of the control device of the fluid transmission from forward to backward and vice versa must be simultaneous proceed with the adjustment of the piston stroke of the rotating piston pump.

In der Zeichnung ist eine Ausführungsform der Zusatzerfindung beispielsweise dargestellt. Abb. z zeigt den Schnitt einer Regelungsvorrichtung im Flüssigkeitswechsel- und Wendegetriebe, Abb. 2 einen Schnitt nach der Linie A-B der Abb. r, Abb.3 einen Schnitt einer Regelungsvorrichtung bei anderer Lage der Glieder des Flüssigkeitsgetriebes zueinander und Abb. 4 einen Schnitt nach der Linie C-D der Abb. 3.In the drawing, an embodiment of the additional invention is for example shown. Fig.z shows the section of a control device in the fluid change and reversing gear, Fig. 2 a section along the line A-B in Fig. r, Fig.3 a Section of a control device with a different position of the links of the fluid transmission to each other and Fig. 4 a section along the line C-D of Fig. 3.

Die Regelungsvorrichtung r des Flüssig keitsgetriebes 2 ist mittels der Kegelräder 3 und 4 einstellbar, und die Kegelräder 5 und 6 dienen zum Einstellen der Regelungsvorrichtung 7 der kreisenden Kolbenpumpe B. Die Kegelräder 4 und 6 sitzen auf derselben Welle, die durch das Glied 9 gedreht werden kann, so daß eine gemeinsame Bedienung beider Regelungsvorrichtungen r und 7 mittels der einzigen Bedienungsvorrichtung 9 möglich ist.The control device r of the liquid keitsgetriebes 2 is means the bevel gears 3 and 4 are adjustable, and the bevel gears 5 and 6 are used for adjustment the control device 7 of the rotating piston pump B. The bevel gears 4 and 6 sit on the same shaft that can be rotated by the link 9, so that a joint operation of both control devices r and 7 by means of the only one Operating device 9 is possible.
