<p>A method is provided for obtaining braking capacity from the engine-transmission unit of a hydromechanical vehicle transmission having a torque converter in combination with a plurality of mechanical gear steps. The braking force is provided by running the turbine member faster than the engine, either with the guide member of the torque converter kept stationary or released so as to be free to rotate and with the torque converter's direct drive clutch released, and with the pump member of the torque converter connected to the rotating casing of the torque converter which is connected to the engine. The braking capacity is regulated by regulating the engine speed and changing the gear ratios. Regulation of the engine speed can be accomplished by throttling the exhaust or, under other circumstances, by causing the engine to rotate faster.</p> |
