<p>A hydraulic-controlled differential (10) includes a case (12) defining a central chamber with intermeshed control gears (52-58) different ones of which are drivingly-connected via shaft and gear arragements (60-66, 88, 90, 94, 98 and 102) through side chambers to opposite output shafts (86). The central and opposite side chambers of said case (12) are interconnected for fluid communication via control valves (113) for controlling flow of hydraulic fluid between the chambers to effect hydraulic modulation during differential drive for more controllability. A second embodiment (150) for lighter-duty applications incorporates two control gears (152, 154).</p> |
