Abstract
Automated multi-stage gearbox, includes a basic gearbox with a number of gears and a two-stage split gearing coupled in front of and in series with the basic gearbox. Shifting is effected by compressed-air cylinders which are controlled by a control computer (45) which is programmed to put the split gearing in a neutral position in the event of an input signal representing zero throttle.
