ABSTRACT:
An axle driving apparatus of the present invention consists of a hydrostatic transmission for driving a vehicle. The transmission is so designed that a fan is disposed on a power input shaft so as to cool a housing as well as cooling tubing or an oil passage disposed between the fan and the upper surface of the housing. The housing of the axle driving apparatus is filled with lubricating oil, used on the gears and bearings of the power transmission from the hydrostatic transmission to the axles, and operating oil, used in the pump and motor of the hydrostatic transmission. The oil circulates within the tubing or the oil passage. Cooling the oil passing in the tubing or the oil passage prevents a deterioration in efficiency of the axle driving apparatus.
