Abstract

The invention relates to a remote control device of a gear-box for motor vehicles with incorporated compressed-air system. A gear-shifting gate with servo-pneumatic control provided at the gear-box for setting the gears comprises substantially two working cylinders controlled by servo-valves whose travels are signalled via position indicator switches. A gearshift lever console in the driver's cabin transmits the shifting commands via position indicator switches to electronic control means which in turn control the gear-shifting gate at the gear-box. For feeding back to the gearshift lever the shifting states prevailing at the gear-box, a working cylinder is provided in the gearshift lever console which acts directly on the gearshift lever via a mechanical link.
