Abstract
Abstract The present invention, firstly, lowers the lower end of pump shaft to lower the belt transmitting mechanism to thereby provide the axle driving system for the integral hydraulic transmission matching with the running vehicle of lower floor system, which is concretely the L-like-shaped center section fixed within the axle casing, so that the upper surface of the horizontal portion of the L-like-shaped center section is used as the pump mounting surface 3b, the position of which is set lower than the fixedly junction surface of the axle casing. The present invention, secondly, provides the axle driving system which is capable of quickly putting the hydraulic transmission at the axle casing in the operable state when assembled. Concretely, at the center section in the axle casing are provided the second charge ports 3s and 3t which can manually supply operating oil into the closed circuit from the exterior of the axle casing.
