<p>An efficient electronic gearbox is described suitable for use as: an automotive overdrive, a retrofitted automotive overdrive, a reverse gear, and useful in wind turbines and marine applications. The gearbox enables a direct drive coupling between an input shaft (2) and an output shaft (5) or shifting to drive through one or more gear trains to provide a mechanical advantage and/or reverse gear. When shifted to the direct drive mode the gear train (12, 13, 15, 16) is uncoupled from the drive input and output. Shifting is facilitated by synchromeshes (11, 19, 20) actuated by electronically controlled actuators which obviate mechanical linkages.</p> |
