PURPOSE:To obtain a motormanless mobile vehicle to be used for performing maintenace and inspection within a reactor by providing front and rear wheels with auxiliary wheels to get over obstacles which are power supplied from a driving and steering motor and remote controlled with a minimum electric wiring. CONSTITUTION:A connection rod 13 is ball-jointed with a center disc 5 engaged with a front axle 1 and a rock 14 is engaged with a pinion of an output shaft of the steering motor 15. The front auxiliary wheels 18, 19, 20, 21 are projected from the peripheral edges of the front wheels. The rear axle 2 is rotated by the driving motor 9 through a bevel gear 10. The rear auxiliary wheels 28, 29, 30, 31 are associated with the rear axle 2 through a pair of chains 32, 33 to rotate at the same circumferential speed. This enables a smooth travelling and reduces the inclination and shock generated when the wheels get over the obstacles. Such a car is very prominent as the mobile vehicle equipped with many precision instruments for performing the maintenance and inspection of the reactor. |
