    • A vertical power unit includes an input shaft and an output shaft which have axes in the vertical direction and are vertically arranged to each other; and a torque converter between the input shaft and the output shaft. The output shaft includes an upper output shaft connected to a turbine runner and a lower output shaft connected to the upper output shaft. An oil tank and an oil pump are provided outside the torque converter. The upper output shaft is provided with a vertical hole which communicates at an upper end with a circulation circuit of the torque converter so as to introduce the oil discharged by the oil pump into the circulation circuit, and a bottom wall which closes a lower end of the vertical hole. Thus, an working oil is constantly supplied to the circulation circuit of the torque converter through the interior of the output shaft, thereby cooling the working oil in the circulation circuit, and improves maintainability of loading devices driven by the output shaft.
    • 垂直动力单元包括输入轴和输出轴,其具有在垂直方向上的轴线并且彼此垂直布置; 以及在输入轴和输出轴之间的变矩器。 输出轴包括连接到涡轮机转轮的上输出轴和连接到上输出轴的下输出轴。 变矩器外部设有油箱和油泵。 上输出轴设有垂直孔,上下孔与变矩器的循环回路连通,将由油泵排出的油引入到循环回路中,底壁将下端 垂直孔。 因此,通过输出轴的内部将工作油不断地供给到变矩器的循环回路,从而冷却循环回路中的工作油,提高由输出轴驱动的装载装置的维护性。
