Abstract:
A vehicle with an auxiliary traveling device comprising:a power train including a primary power transmission for normal traveling, which is connected to a traveling prime mover for normal traveling, for transmitting a rotational torque of said traveling prime mover to driving wheels, through a rotary power transmission shaft, a drive shaft speed reducer and a drive shaft;an external power takeoff mechanism incorporated in said primary power transmission;a hydraulic pressure generator connected to an external power takeoff shaft of said external power takeoff mechanism;a hydraulically controlled power transmission for traveling at inching speed, which includes a hydraulic motor connected to said hydraulic pressure generator;said power train being active for enabling the vehicle to travel at a normal traveling speed while said primary power transmission for normal traveling is placed at a range position other than neutral range position,said auxiliary traveling device being operated for enabling travel at inching speed when said primary power transmission for normal traveling is placed at neutral range position, andwhen said primary power transmission for normal traveling is shifted out of said neutral range position, said external power takeoff mechanism and said hydraulically controlled power transmission for traveling at inching speed being made inoperative instantly in response to an electrical signal from a neutral position detector incorporated in said primary power transmission for normal traveling.
