Demnach wird ein hydrostatisch-mechanisches Leistungsverzweigungsgetriebe vorgeschlagen, umfassend einen mechanischen und einen hydrostatischen Leistungszweig, die in einem Summierungsgetriebe zusammengeführt werden, wobei der hydrostatische Leistungszweig eine Hydrostateinheit aufweist, umfassend eine Pumpe und einen Motor und wobei das Summierungsgetriebe Planetensätze und Schaltelemente aufweist, durch deren Kombination vier Fahrbereiche in Vorwärtsrichtung schaltbar sind, bei dem in Kraftflussrichtung zwischen dem hydrostatischen Leistungszweig und dem Summierungsgetriebe eine Schalteinrichtung vorgesehen ist, über die der hydrostatische Leistungszweig wahlweise über eine erste oder eine zweite Übersetzungsstufe mit dem selben Element des Summierungsgetriebes verbindbar ist, wobei über die erste Übersetzungsstufe eine Übersetzung ins Schnelle erzielt wird, so dass im Summierungsgetriebe eine Drehrichtungsumkehr zur Rückwärtsfahrt realisiert wird.Therefore becomes a hydrostatic-mechanical power split transmission proposed comprising a mechanical and a hydrostatic Power branch, which merged in a summation gearbox with the hydrostatic power branch having a hydrostatic unit, comprising a pump and a motor and wherein the summation gear Planet sets and switching elements has, by the Combination four driving ranges are switchable in the forward direction, in the direction of force flow between the hydrostatic power branch and the summation a switching device is provided via the hydrostatic power branch either via a first or second translation stage with the same Element of the summation gear is connectable, with over the first translation stage a translation into Fast is achieved, so that in the summation gear reversing the direction of rotation is realized for reversing.
Demnach erfolgt die Vorwärts- und die Rückwärtsfahrt durch Antreiben des gleichen Elementes des Summierungsgetriebes.Therefore the forward and the reverse drive takes place by driving the same element of the summation gear.
Gemäß der Erfindung erfolgt die Schaltung zwischen Vorwärts- und Rückwärtsfahrt und umgekehrt bei einer Geschwindigkeit von 0 km/h ohne Stufenspannung, wobei die Rückwärtsfahrt im ersten Fahrbereich realisierbar ist und wie die Vorwärtsfahrt stufenlos erfolgt.According to the Invention, the circuit between forward and Reversing and vice versa at a speed from 0 km / h without step voltage, with the reverse drive in the first driving range is feasible and like the forward drive stepless he follows.
Vorzugsweise
ist die Schalteinrichtung abtriebsseitig mit einem Sonnenrad eines
Planetensatzes des Summierungsgetriebes verbunden. Insbesondere

mit dem Sonnenrad verbunden ist, mit dem der hydrostatische Leistungszweig bei
einem hydrostatisch-mechanischen Leistungsverzweigungsgetriebe nach
dem Stand der Technik ohne die erfindungsgemäße
Schalteinrichtung gemäß
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass die Schaltreinrichtung eine Rückwärtskupplung und eine Vorwärts kupplung umfasst, wobei über die Rückwärtskupplung der Leistungsfluss über die erste Übersetzungsstufe und über die Vorwärtskupplung der Leistungsfluss über die zweite Übersetzungsstufe erfolgt.According to one advantageous embodiment of the invention is provided that the switching device is a reverse clutch and a forward clutch comprises, over the reverse clutch the power flow over the first gear ratio and the forward clutch the power flow through the second translation stage he follows.
