METHOD FOR AUTOPILOTING TRANSMISSION AND SELF-TRAILING TRANSMISSION DEVICE FOR TRAILER VEHICLES, ESPECIALLY FOR TRACHED SENDING MACHINES, ATTACHABLE TO A SELF-PROPELLING VEHICLE

摘要

The method involves detecting displacement direction of mechanical unit i.e. drive wheels (4), of a train from stop position and by using twin sensors (7a, 7b), where movement direction of the mechanical unit indicates displacement direction controlled by a cockpit of the train for sending information concerning the movement direction to a logic controller. Adequate control of a pump of hydraulic propulsion system of a towed vehicle (1) or electric gear motor driving wheels of electric propulsion system of the towed vehicle, is guided by the logic controller. An independent claim is also included for a self-controllable transmission device for towed vehicles hitched to a self-propelled vehicle e.g. towed grape harvesting machine, comprising twin sensors or double sensor.
