Abstract
Abstract An axle driving apparatus which houses a hydraulic non-stage transmission in a casing comprised of at least two casing members and coupled by a substantially flat coupling surface formed therebetween. The casing also houses an output shaft of the hydraulic non-stage transmission which is offset in parallel to the coupling surface. This construction allows for simple manufacture and maintenance of the hydraulic non-stage transmission and axles, provides for a smaller downward projection of the casing thereby reducing interference with obstacles on the ground, improves sealing capability of the casing when a braking unit is attached to one axial end of the output shaft, and reliably bears the thrust of the hydraulic motor.
