ABSTRACT:
Arrangement for preventing incorrect shifting in a gearbox having a base portion and a two-speed range portion has a gear selector mechanism coupled to a shift unit and comprising a first blocking system coordinated with the shift unit of the range portion and the gear selector mechanism of the base portion to block shifting in the base portion during shifting of the shift unit in the range portion, and a second blocking system coordinated with means for sensing the rotational speed of the output shaft and with the gear selector mechanism of the base portion to prevent shifting to certain gears in the base portion when the rotational speed of the output shaft exceeds certain values. First and second blocking systems have a common blocking device. The first system has apparatus sensing the shifting movement of the shift unit and disposed to activate the blocking device to block the gear selector of the base portion in the neutral position during shifting. The second system has apparatus for sensing the lateral position of the gear lever and disposed, depending on the rotational speed of the output shaft, in the lateral position of first and second gear to actuate the blocking device to block the gear selector of the base portion in the neutral position.
