摘要： Die vorliegende Erfindung betrifft ein Verfahren zur Regelung eines hydraulischen Antriebssystems, insbesondere eines Krans oder einer Baumaschine, das einen geschlossenen Hydraulikkreis mit einer Hydraulikpumpe und einem Hydraulikmotor umfasst, bei dem in Abhängigkeit eines Soll-Werts eines Abtriebsparameters des Hydraulikkreises ein Stellsignal zur Einstellung der Hydraulikpumpe und/oder des Hydraulikmotors bereitgestellt wird. Die Erfindung betrifft weiterhin eine Vorrichtung zur Regelung eines solchen hydraulischen Antriebssystems, das einen geschlossenen Hydraulikkreis mit einer Hydraulikpumpe und einem Hydraulikmotor umfasst, mit einem Stellsignalkreis zur Erzeugung eines Stellsignals für die Hydraulikpumpe und/oder den Hydraulikmotor in Abhängigkeit eines Soll-Werts eines Abtriebsparameters des Hydraulikkreises. Die Erfindung betrifft schließlich einen Kran und/oder eine sonstige Baumaschine mit einem hydraulischen Antriebssystem, das einen geschlossenen Hydraulikkreis mit einer Hydraulikpumpe und einem Hydraulikmotor umfasst, sowie einer Regelvorrichtung zur Regelung des hydraulischen Antriebssystems mit einem Stellsignalkreis zur Erzeugung eines Stellsignals für die Hydraulikpumpe und/oder den Hydraulikmotor in Abhängigkeit eines Abtriebsparameters des Hydraulikkreises. Es wird eine Regelung vorgeschlagen, deren Prinzip darauf basiert, die Stellsignale, die für die einzelnen hydraulischen Komponenten aufgrund der gewünschten Abtriebsparameter bestimmt werden, durch Überprüfung von Leistungsvorgaben, die extern oder intern vorgegeben werden können, zu begrenzen bzw. zu reduzieren, um hierdurch die Stabilität des Systems zu gewährleisten. Die erzeugten Stellsignale werden so begrenzt bzw. reduziert, dass die vom Hydrauliksystem erzeugte Leistung und/oder die in das Hydrauliksystem rückgeführte Leistung die Leistungsvorgaben nicht überschreitet. Erfindungsgemäß wird das Stellsignal in Abhängigkeit eines Abgleichs eines vorgegebenen Leistungswerts mit einem aktuellen Leistungswert der Hydraulikpumpe und/oder des Hydraulikmotors von einem übergeordneten Steuerungsbaustein begrenzt und/oder reduziert. Hierdurch können zu rasche und/oder zu große Stellbewegungen der Stellorgane der Hydraulikkomponenten verhindert werden, die zu Unstabilitäten des Antriebssystems und/oder zu unerwünschten Abtriebsparametern führen würden.

摘要： The invention relates to a hydrostatic drive comprising a hydraulic pump (1) and at least one hydraulic engine (3). Said hydraulic engine (3) is contacted to a closed circuit via a first working line (5) and a second working line (6). In order to limit the swept volume flowing in one of the two working lines (5) towards the hydraulic pump (1), a volume flow divider (60) is provided in the working line (5) and allows to remove a partial volume flow from the working line (5).

摘要： Smaller and lighter hydraulic pump/motors provide remarkably improved volumetric efficiency with pistons having body portions substantially as long as the axial length of the respective cylinders in which they reciprocate. A plurality of respective lubricating channels, formed circumferentially and radially transecting the walls of each cylinder, are each positioned to be almost completely closed at all times by the axial cylindrical body of each respective piston during its entire stroke. Each lubricating channel is interconnected, one to another, to form a single, continuous lubricating passageway entirely within the cylinder block and not connected by either fluid 'input' or fluid 'output' passageways, being replenished solely by a minimal flow of fluid entering from the valve end of each cylinder and passing between each respective cylindrical wall of each cylinder and the axial cylindrical body of each respective piston. Several embodiments are disclosed in combination with various spring-biased hold-down assemblies.

摘要： A vehicle (A) has an HMT (T) mounted thereon that once divides an input rotating force from an engine (13) into two systems and transmits them respectively to an MT (23) and an HST (24), and then recombines them and delivers the same to wheels (12, 16). The HMT (T) is disposed on the vehicle body right-hand side of an engine (13) transversely mounted on the vehicle body (1), and an input shaft (25) and an output shaft (26) are disposed parallel with the crank shaft (13a) of the engine (13) and side by side with each other. The input shaft (25) is connected directly to the crank shaft (13a), and the input gear (27) of the MT (23) is disposed on the shaft, while the hydraulic piston pump (30) of the HST (24) is connected to the vehicle body right-hand side end of the input shaft (25). The planetary gear mechanism (28) of the MT (23) is connected to the vehicle body right-hand side end of the output shaft (26), and connected to the vehicle body right-hand side thereof is the hydraulic piston motor (31) of the HST (24). This arrangement improves the degree of freedom of layout of the components in the HMT (T), reduces the axial dimension, and improves the coolability and maintainability of the HST (24) portion.
