    • A power of an input shaft driven by an engine is divided by a power dividing device and transmitted to first and second output shafts and a hydraulic pump of a hydrostatic continuously variable transmission is driven by the first output shaft, whereas a hydraulic motor is driven by the second output shaft through a mechanical transmission device and also by the hydraulic pump. A main oil pump is provided at the input shaft which rotates at the same speed as an engine speed, and a subsidiary oil pump is provided at the first output shaft which decreases rotational speed thereof to zero with an increase in the engine rotational speed. In a low rotational speed region of the engine, oil is supplied by both the main oil pump and the subsidiary oil pump, whereas in a high rotational speed region of the engine, oil is supplied by only the main oil pump. With this construction, it is possible to prevent a waste of energy required to drive the oil pump in the high rotational speed region of the engine while ensuring the quantity of oil supply from the oil pump in the low rotational speed region of the engine.
    • 由发动机驱动的输入轴的动力由动力分配装置分开,传递到第一输出轴和第二输出轴,液压无级变速器的液压泵由第一输出轴驱动,液压马达由 第二输出轴通过机械传动装置和液压泵。 主输油轴设置在与发动机转速相同的速度旋转的输入轴上,并且在第一输出轴处设置有辅助油泵,其随着发动机转速的增加而将其转速降至零。 在发动机的低转速区域中,油由主油泵和辅助油泵两者供油,而在发动机的高转速区域中,仅由主油泵供油。 通过这种结构,能够在确保从发动机的低转速区域的油泵供油量的同时,防止在发动机的高转速区域内驱动油泵所需的能量的浪费。

    • A shift control apparatus for an automatic transmission having an automatic shift mode for performing a shift operation by determining a gear ratio to be set according to a vehicle running condition and a manual shift mode for performing a shift operation instructed by a manual operation by an operator. The shift control apparatus includes a vehicle speed comparing unit for comparing a vehicle speed at the time of inputting a first manual shift command for downshift to a predetermined gear ratio in the manual shift mode and a vehicle speed at the time of inputting a second manual shift command for downshift during a first shift control period from the time of inputting the first manual shift command to the time of completing first shift control according to the first manual shift command, and a successive shift allowing unit for allowing the downshift by the second manual shift command when the vehicle speed comparing unit has determined that the vehicle speed at the time of inputting the second manual shift command is lower than the vehicle speed at the time of inputting the first manual shift command.
