<p>A hydromechanical transmission having plural power paths, one being a mechanical path and the other being a hydraulic path with an output differential for combining the torque of the two paths and providing an output for the transmission, there being provided a low speed plural path mode effected by clutching one of the differential elements to the input shaft, and a high speed straight hydraulic mode effected by locking the differential elements together for rotation as a unit. Both the low and high speed modes have forward and reverse speeds. A transmission ratio and mode control is provided that compensates for the difference in hydraulic displacement in the two modes so that the transmission may be easily shifted from zero output in the low speed mode to zero output in the high speed mode and vice versa.</p> |
