| 摘要 |
A hydraulic power transmission apparatus for reducing the speed of rotation of output from a power source and changing the speed of rotation thereof at a given transmission ratio, includes an oil pump having a drive shaft to which the power from the power source can be applied, the oil pump being drivable by the power from the power source, a pair of oil motors having output shafts, respectively, and associated with a pair of axles, respectively, the oil motors being drivable by hydraulic pressure generated by the oil pump, a pair of speed reducer mechanisms disposed between the outupt shafts of the oil motors and the axles for reducing the speeds of rotation of the output shafts, respectively, and transmitting the rotation of the output shafts to the axles, respectively, an inner case having a closed space defined therein, the oil pump and the oil motors being housing in the closed space, and a transmission case having a transmission chamber defined therein, the inner case and the speed reducer mechanisms being housed in the transmission case, the transmission case storing oil therein.
