Abstract

Ein hydrostatisch leistungsverzweigtes Getriebe (10), insbesondere für Land- und Baufahrzeuge, umfasst wenigstens zwei Hydrostaten (H2), welche hydraulisch untereinander in Verbindung stehen und als Pumpe bzw. als Motor arbeiten, wobei wenigstens einer der Hydrostaten (H2) mittels einer Steuerung (16, 20, 21; SK1,..,SK4) verstellt bzw. verschwenkt werden kann, mechanische Kopplungsmittel (K1, K2; Z1,..,Z12), welche die Hydrostaten (H1, H2) mit einer inneren Antriebswelle (W1) und einer inneren Abtriebswelle (WT) koppeln, ein einen Deckel (14) und ein Gehäuseunterteil (31) umfassendes Gehäuse (14, 31), wobei die Hydrostaten (H1, H2), die inneren Antriebs- und Abtriebswellen (W1, W7) und die mechanischen Kopplungsmittel (Z7, Z9) auf der Unterseite des Deckels (14) angeordnet und befestigt sind, und im Gehäuseunterteil eine von aussen zugängliche äussere Antriebswelle und Abtriebswelle gelagert sind, welche bei zusammengebautem Gehäuse mit der inneren Antriebswelle bzw. Abtriebswelle in Wirkverbindung stehen. Bei einem solchen Getriebe wird ein kompakter Aufbau bei leichter Zugänglichkeit und grosser Flexibilität bei der Anpassung an unterschiedliche Fahrzeuge dadurch erreicht, dass die Steuerung (16, 20, 21; SK1,..,SK4) zur Verstellung bzw. Verschwenkung des wenigstens einen Hydrostaten (H2) auf der Oberseite des Deckels (14) angeordnet ist und durch den Deckel (14) hindurch auf den wenigstens einen Hydrostaten (H2) einwirkt.
