Description

Hydraulischer Antrieb, insbesondere für Fahrzeuge Zusatz zur Patentanmeldung H 13s169 II/63 c (Auslegeschlift 1021 251) Die in der Hauptpatentanmeldung dargestellten Einrichtungen können auch bei Antriebsanordnungen verwendet werden, die weder ein Uberlagerungsgetriebe noch eine hydrostatische Kupplung aufweisen. Es kann sich hierbei auch um die an sich bekannte Anordnung handeln, bei welcher ein hydrostatisches Getriebe durch zwei Zahnrädervorgelege und einen Wellenzug überbrückt ist. Im Gegensatz zu dieser befindet sich bei der in der Abbildung beispielsweise gezeigten Anordnung die lösbare Kupplung im Wellenzug ; außerdem kann das hydraulische Getriebe Hg dazu benutzt werden, um die Schaltklauen zu entlasten. Hierzu ist es nötig, das hydraulische Getriebe so auszulegen, daß es wenigstens kurzzeitig das Nutzdrehmoment übertragen kann. Dies stellt insofern eine Verbesserung gegenüber den in der Hauptpatentanmeldung beschriebenen Anordnungen dar, als bei ausgeschalteten KlauenSK das hydraulische GetriebeHg auch noch zur Drellzahlregelung verwendet werden kann wie auch zur Angleichung der Relativgeschwindigkeit der Schaltklauen SK vor ihrer Einschaltung auf die für das Zusammenschalten zweckentsprechende geringe Relativgeschwindigkeit. Hydraulic drive, especially for vehicles. Addendum to patent application H 13s169 II / 63 c (Auslegeschlift 1021 251) The ones shown in the main patent application Devices can also be used in drive arrangements that have neither a Overlay transmission still have a hydrostatic clutch. It can this also involves the arrangement known per se, in which a hydrostatic Transmission is bridged by two gear reducers and a shaft train. In contrast to this is located in the arrangement shown in the figure, for example the releasable coupling in the shaft train; In addition, the hydraulic transmission Hg can do so can be used to relieve the shifting claws. For this it is necessary to use the hydraulic Gearboxes should be designed in such a way that they transmit the useful torque at least for a short time can. To that extent, this represents an improvement over that in the main patent application described arrangements than when the KlauenSK is switched off, the hydraulic Gear Hg can also be used to control the twist ratio as well as for adjustment the relative speed of the switching claws SK before they are switched to the for the interconnection appropriate low relative speed.

Der Fortschritt gegenüber dem Antrieb-der Hauptpatentanmeldung besteht darin, daß im Hauptantrieb keine Kupplung mehr nötig ist, ferner daß überhaupt bei diesen Schaltoperationen die Leistungs-oder Drehmomentabgabe nicht unterbrochen werden muß und daß ferner das hydraulische Getriebe gleichzeitig die Regelung mit übernehmen kann. The advance over the drive-the main patent application exists in the fact that the main drive no longer needs a clutch, and that at all These switching operations do not interrupt the power or torque output must be and that also the hydraulic transmission with the control at the same time can take over.

Ein Druckzylinder Z mit dem Kolben K, welcher genau so geschaltet ist wie der Druckzylinder in den Abb. l und 3 der Hauptpatentanmeldung, kann in derselben Weise, wie dort beschrieben, zur Entlastung der Schaltklauen vor ihrer Entkupplung dienen. Die dort angegebenen Einrichtungen können unverändert übernommen werden, und es sind in der Zeichnung daher auch die gleichen Bezeichnungen angewendet vorden. A pressure cylinder Z with the piston K, which is switched in exactly the same way is like the printing cylinder in Figs. 1 and 3 of the main patent application, can in the same way as described there, to relieve the shifting claws in front of their Serve decoupling. The facilities specified there can be adopted unchanged and therefore the same designations are used in the drawing Before.
