What looks like an industrial-strength blender is actually the DN-01's hydro-mechanical Human Friendly Transmission. Basically, it's comprised of a pump and a motor, with a pair of swash plates-designed to turn rotational energy into the reciprocating kind-and a volume of engine oil in between. A circular array of seven pistons on the pump side turns engine power into hydraulic pressure, which moves nine pistons on the motor side, turning the HFT output shaft and, ultimately, the rear wheel. Changing the angle of that motor-side swash plate changes the stroke of those motor-side pistons, which produces continuously variable drive ratios. Increasing the angle increases hydraulic pressure, which increases the amount of torque leaving the transmission.
