<p>PROBLEM TO BE SOLVED: To prevent vibration and the generation of dust by suppressing the looseness of a bogie to a minimum when starting and smoothly travel along a curve without adopting complicated control. SOLUTION: When a left curve is discriminated on the basis of a detection signal from a sensor, a current of a motor 16 on the inner wheel side out of lateral driving wheels 7, 8 supported on both sides of a bogie 12 is cut off to put the inner wheel in free rotation, and a conveying truck 1 travels only with the driving force of the outer wheel (Fig. (a)). When a right curve is discriminated, a current of a motor 15 on the inner wheel side out of the lateral driving wheels 7, 8 is cut off to put the inner wheel in free rotation, and the conveying truck 1 travels only with the driving force of the outer wheel (Fig. (b)). In a linear path, both motors 15, 16 are driven to drive both lateral wheels 7, 8.</p> |
