摘要： The invention relates to a hydrostatic transmission having a hydraulic pump (1) and an adjustable hydraulic motor (2) which is connected to first and second working lines (13, 14) of which at least the first (13) leads to the hydraulic pump, and a setting member (40)--for setting the motor displacement volume--is connected with a setting device (4) which upon load operation of the hydrostatic transmission can be acted upon by a setting pressure in a first setting pressure line (44, 57, 43) connected at least to the first working line, and in the case of overrun operation, can be acted upon by the setting pressure in a second setting pressure line (45, 51, 43), connected at least to the second working line. There is a brake valve (6) arranged at least in the second working line downstream of the connection of the second setting pressure line and which upon overrun operation of the hydrostatic transmission the respective working line is restricted. In order to be able to adapt the braking effect to differing operating conditions, there is provided a relief valve device (9, 10) which upon overrun operation is controlled by means of a control pressure taken from the second setting pressure line (45, 51, 43), against a counter-pressure (66, 76) in the direction of throughflow position and in this throughflow position relieves the setting pressure in the second setting pressure line (45, 51, 43) controllably via a relief line (65) to the tank (12).

摘要： An axial piston machine is provided. A housing of the machine receives an eccentric disk and a rotatably mounted cylinder drum. The drum has cylinders and pistons. The pistons are reciprocatable in the cylinders. The ends of the cylinders project from the cylinders and are supported via sliding blocks against a sliding surface on the eccentric disk. The sliding blocks are held in abutment with the sliding surface through a holding-down device. A pressure prevailing in a pressure chamber under the sliding blocks by a throttle point partially compensates a force that is exerted by the holding-down device on the sliding blocks, through a hydraulic pressure between an annular seating surface of the sliding blocks and a support surface of the holding-down device.

摘要： A hydrostatic drive with first and second hydraulic pumps and a dual-acting hydraulic cylinder. The dual-acting hydraulic cylinder has a first working chamber defined by a first piston surface and a second working chamber defined by a second piston surface. The first working chamber is connected to first connections of the first and second hydraulic pumps. The second working chamber is connected to a second connection of the second hydraulic pump. A second connection of the first hydraulic pump is connected to a hydraulic fluid reservoir. The ratio of the first piston surface to the second piston surface differs from the ratio of the total delivery volume of the two hydraulic pumps relative to the delivery volume of the second hydraulic pump. A tapping valve for removing hydraulic fluid is provided for the volumetric flow equalisation.
