PURPOSE:To correct the travelling direction accurately in desired direction by indicating the steering and the direction upon occurrence of machine body steering due to the difference of slip between the steering wheel and the driving wheel. CONSTITUTION:A potentiometer 5 is fixed to a rolling interlocking tool 8 for interlocking respective knuckle arm 6 of a pair of front axles 1a, 1b and the steering wheel to detect the rolling direction and the rolling angle of said tool 8 against the machine body 8. While sensors 9, 10 for detecting the rotary direction and the rotary speed of rear wheel are fixed to the output shafts 12a, 12b of the wheel differential mechanism 11 for the rear wheels 2a, 2b. The outputs from a potentiometer 5 and the sensors 9, 10 are fed to an arythmetic circuit 14 to decide the steering direction and the steering angle of the machine body caused on the differential slip by means of a decision mechanism 16. |
