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： The invention relates to a control and regulating device for a hydrostatic transmission which comprises a reversible hydraulic pump that can be driven by a driving motor, at least one hydraulic motor that is connected via two working lines to the hydraulic pump, and an adjusting device that can be acted on by an adjusting pressure for adjusting the volume and direction of displacement of the hydraulic pump, together with a displacement-direction control valve for controlling and regulating the action of the adjusting pressure on the adjusting device, can be actuated as desired both by a control signal that is proportional to the speed of rotation of the driving motor and predetermines the direction of displacement of the hydraulic pump and by a working pressure signal that is proportional to the working pressure in the working line then carrying the high pressure. To enable a load that has been decelerated to a standstill both to be maintained at a standstill and also to be shunted without mechanical braking, even when actuation of the displacement-direction control valve by the control signal is interrupted, the invention provides for switching over the working pressure signal applied to the displacement-direction control valve in the absence of the control signal.
