摘要： A drive system for machines and vehicles with a hydraulic and mechanical transmission arranged thereafter having a driving motor and a control member which can continuously vary the speed of the motor. A hydraulic converter also controlled by a control member dependent upon the speed of the driving motor and the running pressure of the motor is also provided, in which a transmission arranged after the converter and a shifting mechanism is connected to an electronic control circuit so that an operating element for shifting gears of the transmission may achieve a comfortable shifting behavior for the transmission. Shifting from a high gear to a low gear will occur only under the following conditions: (a) before shifting, the output speed of the hydraulic converter is below a certain predetermined value, and (b) before shifting, the transmission ratio of the converter reaches a specific minimum value caused by the working pressure of the motor.

摘要： An automotive drive system for machines and vehicles, comprising a driving motor the speed of which can be continuously varied by means of a control member and a converter having control means for controlling its output speed in dependence on a depression of the speed of the driving motor determined by means of signal transmitters is arranged so that the power or torque available from the driving motor is better employed. This is achieved by controlling (adjusting) the converter to minimum transmission ratio independently of the driving motor speed when the driving motor speed resulting during operation of the drive system is greater than the driving motor speed given by a predetermined speed(rotation) depression, and on reaching the predetermined speed (rotation) depression the converter is controlled in dependence on the driving motor speed so that the driving motor speed does not fall below the controlling characteristic curve corresponding to the predetermined speed (rotation) depression.

摘要： A control device for a hydrostatic drive for at least two actuators, having a variable displacement pump whose adjusting device is acted on in accordance with the displacement and/or the flow pressure, wherein each actuator has associated with it, in its hydraulic supply line, a control valve and a preceding displacement controller in the form of a pressure compensator, is simplified while ensuring accurate control. This is achieved by associating with the control device an electronic regulating device which, depending on a measuring element that detects the opening position of the pressure compensator, controls, by means of an adjusting member associated with the adjusting device, the displacement setting of the pump, increasing it as the opening of the pressure compensator(s) becomes larger and decreasing as the opening becomes smaller.
