AUTOMATIC GEARSHIFTING PROCESS FOR A VEHICLE WITH ENGAGED COUPLING-DEPENDENT POWER TAKE OFF AND AUTOMATIC DISENGAGEMENT PROCESS OF A COUPLING-DEPENDENT POWER TAKE OFF

摘要

The automatic gear-changing process is for a vehicle with a coupling-dependent power take-off connected when the vehicle is in movement. The power take-off (32) is driven by an engine (1) in the vehicle by at least one coupling (3), which in turn is coupled to an automatic stage-geared gearbox (9) in which there is at least one intermediate shaft (11) used for driving the power take-off. The gearbox, engine and power take-off are controlled by at least one control unit (45). The control unit limits the effect take-off in the power take-off during at least a part of the gear-changing process when the intermediate shaft is uncoupled from the vehicle drive wheels, which limits the torque loading of the power take-off over the gearbox.
