ABSTRACT:
A gearbox for automotive applications which includes an input shaft, an output shaft and a countershaft avoids driving the countershaft when in a direct drive mode by providing a selective coupling and decoupling mechanism. An input gear is mounted for free rotation about the input shaft when the gearbox is in a direct drive mode, thus eliminating the wasted energy in driving the countershaft and the change-speed gears thereon. When in a reduced or change-speed gear mode, the input gear is coupled for rotation with the input shaft to drive the countershaft. Alternatively, the countershaft may be provided with a countershaft input gear which can be selectively coupled and decoupled therefrom. The gearbox hereof preferably operates with a synchromesh gearbox and occupies no greater space and far less energy than conventional synchromesh gearboxes.
