<p>An integrated hydromechanical axle driving device (2), comprising a pair of drive axles (40L, 40R), a differential mechanism (5) differentially connecting both drive axles to each other, a hydraulic continuously variable transmission mechanism (21) for drivingly traveling formed by fluid-coupling a hydraulic pump (52) to a hydraulic motor (53), a hydraulic continuously variable transmission mechanism (22) for steering formed by fluid-coupling a hydraulic pump (71) to a hydraulic motor (72), and a transmission mechanism (6) which transmits the outputs of these both hydraulic continuously variable transmission mechanisms to the differential mechanism, all of which are stored in an integrated housing (23), characterized in that at least either of these both hydraulic continuously variable transmission mechanisms is disposed so that the rotating axes of pump shafts (25, 26) cross those of motor shafts (54, 77) perpendicularly.</p> |
