Abstract

Ein Ausgang (19) eines ersten Leistungszweigs (3) ist mit einem ersten Eingang (21) eines Summiergetriebeabschnitts (20) verbunden. Ein Ausgang (44) eines zweiten Leistungszweigs (4) ist mit einem zweiten Eingang (23) des Summiergetriebeabschnitts (20) verbindbar. Der Ausgang (19) des ersten Leistungszweigs (3) ist direkt mit einer Ausgangswelle (29) des Summiergetriebeabschnitts (20) verbindbar. Zum Wechsel von einem rein hydrostatischen Fahrbereich in einen ersten leistungsverzweigten Fahrbereich wird zunächst ein Ausgang eines Summiergetriebeabschnitts (29) durch einen Hydromotor (13) des hydrostatischen Leistungszweigs (3) angetrieben. Die Drehzahl des Hydromotors (13) wird erhöht, bis eine Synchronisationsdrehzahl des anderen Eingangs (23) des Summiergetriebeabschnitts (20) erreicht ist. Anschließend wird der hydrostatische Leistungszweig (3) von dem Ausgang (29) des Summiergetriebeabschnitts (20) getrennt und der mechanische Leistungszweig (20) mit dem anderen Eingang (23) des Summiergetriebeabschnitts (20) verbunden.
