Abstract
An axle driving system, wherein a first chamber and a second chamber partitioned from each other are formed in a housing, a hydraulic non-stage transmission is housed in the first chamber, axles and means for transmitting power from the transmission to the axles is housed in the second chamber. At the upper portion of the housing is disposed an oil storage tank positioned across the first and second chamber. Oil through-bores for flowing oil therethrough are provided in the first and second chambers respectively. At the oil storage tank are provided means in common to charge oil into each chamber. Means for observing oil quantity, and breather means for ventilating outside air are also provided. The first and second chambers are not in direct fluid communication with each other, so that the hydraulic non-stage transmission is not adversely effected by foreign objects, such as iron powder or air bubbles produced by the differential gear, thereby improving durability and reliability and lowering the manufacturing cost.
