摘要： A hydraulic machine (7, 8) includes a rotation shaft (11), a cam (20) configured to rotate with the rotation shaft (11), a plurality of cylinders (22) disposed around the cam (20) each of which includes a distal end portion disposed on an outer side in a radial direction of the rotation shaft (11), a part of the distal end portion being formed by a first curved surface (23), a plurality of pistons (30) disposed around the cam (20) so that end portions of the pistons (30) at an inner side in the radial direction contact a cam surface (21) of the cam (20), the plurality of pistons (30) being configured to reciprocate in the cylinders (22) along a direction of a center axis of the cylinders (22) in accordance with rotation of the cam (20), a stationary member (40) disposed on an outer side of the cylinders (22) in the radial direction, the stationary member (40) including sockets (42) having second curved surfaces (43) which are engageable with the first curved surfaces (23) of the distal end portions of the cylinders (22), and at least one elastic member (60) for biasing the plurality of cylinders (22) outward in the radial direction so as to force the first curved surfaces (23) of the cylinders (22) against the second curved surfaces (43) of the sockets (42). The first curved surfaces (23) of the respective cylinders (22) engage with the second curved surfaces (43) of the sockets (42) so that rocking of each of the cylinders (22) is permitted at least in a plane perpendicular to a rotational axis of the rotation shaft (11).

摘要： Es wird ein Hydrostatgetriebe eines hydrostatisch-mechanischen Leistungsverzweigungsgetriebes angegeben, bei dem die Hochdruckbegrenzungsventile im Hydrostatgetriebe entfallen oder auf ein Niveau eingestellt sind, welches einen Arbeitsdruck ermöglicht, der über dem Arbeitsdruck liegt, der bei einer Dauerbelastung des Hydrostatgetriebes als Maximaldruck zugrundegelegt wird, wobei für kurze Zeitintervalle ein wesentlich höherer Druck einstellbar ist, als der Druck, der bei einer Dauerbelastung des Hydrostatgetriebes als Maximaldruck zugrundegelegt wird, und wobei das Hydrostatgetriebe mit der Steuerung des hydrostatisch-mechanischen Leistungsverzweigungsgetriebes verbundene Hochdruck-Sensoren aufweist.

摘要： A hydrostatic transmission (34, 35) including a variable displacement pump (56) including an input shaft (40) and a pump cylinder barrel rotatably coupled to the input shaft, the pump cylinder barrel having a plurality of cylinder chambers arranged in parallel with other and distributed about the input shaft axis of rotation. Each cylinder chamber has a reciprocating piston therein which bears against a pivotable swashplate, the displacement of the pump being varied in response to changes in the position of the swashplate. A gerotor motor (66) is attached to the pump and has an output shaft (128). The motor includes an engaged pair of inner (120) and outer (118) members, the outer member being eccentric relative to the inner member. The inner member is rotatably driven relative to the outer member by fluid received between the inner and outer members from the pump, the inner member being drivingly connected to the output shaft. A plurality of fluid conduits (58, 60) extend between the pump to the motor, through which the motor is in fluid communication with the pump.

摘要： The invention relates to a hydrostatic-mechanical power split transmission, especially for use in tractors. In order to economically utilize the provided installation space in tractors, the invention provides that the hydrostatic transmission (4) and the planetary drum selector gear (PSW) are arranged together along the same axis and are integrated as a common modular unit in the carrier housing or in the vehicle frame. The transmission also contains the feed pump (279) and the control/regulating device which comprises the electronics. A traversing shaft (PTO) connected to the input shaft (1) is provided for the power take-off connection. The vehicle drive is effected via the drive shaft (336) which can be connected directly or via a corresponding spur gear stage to the pinion input shaft of the axle differential gearing in a manner which is axially offset to the output. The planetary drum selector gear (PSW) is, particularly according to the performance class of the vehicle, configured as a single-range transmission without clutches or as a range-change transmission with two or more clutches. When the transmission is configured as a single-range transmission, a range-shifting transmission which is arranged downstream can be alternatively provided. By virtue of the inline construction, the long installation space which inherently exists in the tractor can be used, and the provision of a very economical and simple structure is made possible. In addition, it is feasible to provide a very important narrow construction for tractors, said construction being determined by the maximum measure X . The transmission can be installed or removed in a few minutes.

摘要： The interior of a rotating body 62 having the shape of a hollow flywheel is made up of a cascade sequence of basins 14 located along a spiral path, formed and perforated 12 likewise the "Nautilus" shell interior; a pressure fluid source 30 feeds the fluid under pressure which is to press on the blades of the spiral; said fluid being linked to a compressor 30,38 which is controlled by the instantaneous pressure. A discharge passage located at the centre of the flywheel 62 and controlled by a shutter, 85 either permits or prevents the fluid escape, a succession of pressures and vacuums and hence a torque being set up by the opening of said passage.
