    摘要： There is provided a working machine which is capable of vehicle speed control through accelerator pedal operation even during execution of work under a condition where engine rotational speed is maintained constant. The working machine has the normal mode for exercising vehicle speed control by controlling engine rotational speed on the basis of the amount of depression of the accelerator pedal and by controlling the swash plate of the HST pump on the basis of the engine rotational speed, and the attachment mode for exercising vehicle speed control by controlling the swash plate of the HST pump on the basis of the amount of depression of the accelerator pedal irrespective of engine rotational speed.

    摘要： Method for the load-dependent regulation of a hydrostatic drive (1), with a closed hydraulic fluid circuit comprising a first hydraulic motor (5) and, parallel to this, a second hydraulic motor (6), whereby both hydraulic motors (5 and 6) are capable of being powered by a hydraulic pump (3) via a high-pressure line (7) and a low-pressure line (8) and are mechanically coupled to each other via a transmission (70). The displacement of the first hydraulic motor (5) can be adjusted proportionally to an electrical signal of an electronic control system (50) by means of an electro-proportional control valve (10) and the displacement of the second hydraulic motor (6) can be adjusted by means of a pressure-proportional control valve (20) which is hydraulically connected to the high-pressure line (7) via a control pressure line (21). The pressure-proportional control valve can be activated by means of a control pressure which is dependent on the high pressure. By means of automatic opening of the pressure-proportional control valve (20) dependent on the high pressure, proportional to the exceedance of a predefinable pressure limit in the high-pressure line (7), the displacement of the second hydraulic motor (6) is adjusted by means of a second servo control unit which can be controlled via the pressure-proportional control valve (20). By means of the electronic control system (50), the actual volume flow passing through the first hydraulic motor (5) is determined and compared with a target value for the volume flow. Based on a deviation between the actual and target value for the volume flow, the electronic control system (50) calculates an adapted control signal and transmits this to the electro-proportional control valve (10), as a result of which the displacement of the first hydraulic motor (5) is adaptable by means of a first servo control unit (14), which is controlled via the electro-proportional control valve (10).

    摘要： It is intended to provide a power generating apparatus of renewable energy type and an operation method of the power generating apparatus, which can achieve both variable speed operation and grid connection without a frequency converting circuit and which uses a hydraulic transmission. In the power generating apparatus of renewable energy type 1, renewable energy received via a blade 4 is transmitted to a synchronous generator 20 via a rotating shaft 8 and a hydraulic transmission 10. The synchronous generator 20 is driven by a hydraulic motor 14 of the hydraulic transmission 10 to generate power. The synchronous generator 20 is connected to a grid without a frequency converting circuit and the power generated by the synchronous generator 20 is supplied to the grid 50. The power generating apparatus 1 is also provided with a transmission controller 40 which controls the hydraulic transmission 10. The transmission controller 40 controls the hydraulic transmission 10 in a normal operation mode to adjust displacement of each of a hydraulic pump 12 and the hydraulic motor 14 such that the rotating shaft 8 rotates at a rotational speed that is variable with respect to flow speed of the renewable energy while keeping a rotational speed of the synchronous generator 20 at a synchronous speed based on frequency of the grid 50 during normal operation of the power generating apparatus.
