摘要： The invention relates to a hydrostatic drive comprising at least one hydraulic pump (1) and a first and a second hydraulic motor (6, 25), which are respectively connected to said hydraulic pump (1) by means of two service lines (4, 41, 5, 5′) and whose absorption volume can be regulated by means of a regulator (40, 41). One respective hydraulic motor (6, 25) for a drive train is provided per respective right or left vehicle side. The regulators (40, 41) are actuated by a respective regulator piston (7, 26). The regulator pistons (7, 26) of both hydraulic motors (6, 25) can be subjected to a force by means of a common high pressure, which equals the highest pressure that prevails in the service lines (4, 41, 5, 5′) of both hydraulic motors (6, 25). Each force is opposed to a respective counter-force, which is generated by a control pressure in a control pressure chamber (11, 11′). The pressure in the control pressure chamber (11)/(11′) of the first and second regulator pistons (7)/(27) of the first and second hydraulic motors (6)/(25) can be reduced by means of first and second pressure regulating valves (17)/(30) in relation to a tank (20) and the first and second pressure regulating valves (17)/(30) are impinged by the respectively higher pressure of the first and second service lines (4, 5)/(4′, 5′) that are allocated to the first and second hydraulic motors (6)/(20), in the form of a controlled variable.

摘要： The invention concerns a control for a hydrostatic power train (1) comprising a hydraulic pump (2) which is connected, via a first main pipe and a second main pipe (7, 8), to a first hydromotor unit (5, 5′) driving a front axle and to a second hydromotor unit (6, 6′) driving a rear axle. The first and second hydromotor units (5, 5′, 6, 6′) can be adjusted in terms of their displacement via a first and a second variation device (30, 31, 30′, 31′) respectively. A direction of travel is defined as forward movement (F) or reverse movement (R) by a position of an operating lever (37). The first and the second variation devices (30, 31, 30′, 31′) are controlled by a control valve (32, 32′) which takes up a first control position upon a forward movement (F) determined by the position of the operating lever (37) and which takes up a second control position upon reverse movement (R) determined by the operating lever (37). In the first control position, the first variation device (30, 30′) is controlled such that the first motor unit (5, 5′) is adjusted for a smaller displacement and, in the second control position, the second variation device (31, 31′) is controlled such that the second motor unit (6, 6) is adjusted for a smaller displacement.

摘要： The invention relates to an axial piston engine (1) comprising a housing (2) wherein a cylinder drum (17) is arranged. Several axially extending piston bores (21) are embodied in the cylinder drum and arranged in such a way that they are distributed around the longitudinal center axis (7a) of the cylinder drum (17). Pistons (23) are moveably guided in said bores and are supported by sliding shoes (29) on a pivoting mounted on a transversely extending pivoting axis (27). A stop (44b) or a stop (44a, 44b) on both sides of the pivoting axis (27) is/are provided in order to limit the pivoting movements of the pivoting plate (26). In order to stabilize the axial piston engine and provide it with a simple design, the stop (44b) or both stops (44a, 44b) are arranged on a sleeve-like supporting element (45) which is supported by the inner covering surface (3c) of the inside of the housing (4).

摘要： The present invention pertains to a dual-function hydraulic valve (1), i.e., a control valve and a pressure reduction or limitation valve at the same time. The inventive combined hydraulic valve (1) encompasses a valve casing (2) with a first central pressure connection (P), a second central pressure connection (Br) and a movable flow check piston (7) in the valve casing (2). The flow check piston (7) presents a pressure surface (16) enabling it (P), when the first central connection is put under supply pressure (P.sub.p), to move from its basic position against an opposing force proportional to said supply pressure (P.sub.p) It also presents a first control ridge (40) and a second control ridge (41). The first control ridge (40) is used to link the first central pressure connection (P) to the second central pressure connection (Br), starting from a first set minimum displacement of the flow check piston (7) which corresponds to a lower threshold value (P.sub.1) of the supply pressure (P.sub.p). The second control ridge (41) is used to break the linkage of the first (P) central pressure connection with both the second central pressure connection (Br) and the pressure surface (16), starting from a set maximum displacement (7) which corresponds to a higher threshold value (P.sub.2) of the supply pressure (P.sub.p).

摘要： A power or moment regulation device for an adjustable hydraulic pump having a servo setting apparatus providing for a smooth stepless setting of the pump delivery quantity. In the device, the delivery quantity setting is determined in dependence upon the delivery pressure of the hydraulic pump in a delivery pressure line and a control pressure in a control line. The setting apparatus has a spring setting a pump setting member in the direction of maximum delivery quantity and a piston acting upon the pump setting member in the opposite direction of delivery quantity reduction. The piston is acted upon via a hydraulically actuated control valve with the delivery pressure. The actuation of the control valve is effected by the control pressure in the control line. A moment valve is provided, the closure force of which is determined by a metering spring arrangement connected with the pump setting member and biased in dependence upon the delivery quantity setting. The moment valve connects the control line with a discharge in dependence upon the control pressure in the control line and the biasing of the metering spring arrangement. A settable choke device, for setting the control pressure acting upon the control valve and the moment valve, is arranged in the control line branching off from the operating pressure line of the pump.
