PURPOSE:To obtain a titled truck for two-direction shifting free from impediments due to flexure of the truck body by connecting driving wheels for lateral movement, driving wheels for longitudinal movement and center wheels provided in consideration of flexure of the truck body to one driving section. CONSTITUTION:When moving laterally, a reduction gear with a motor 1 is driven and a central gear 4 is rotated through rotation of a pinion 2 and an idle gear 3, and driving wheels for lateral movement L, K are driven to shift a truck P laterally. When moving longitudinally, driving shafts 13, 14 are rotated by rotation of a pinion 4 and rotating force is given to left and right driving wheels F, B. Rotating force is also given to a central driving wheel for longitudinal direction D and the truck P is shifted in longitudinal direction. The wheel D, central wheel for longitudinal direction C, central wheels for lateral direction I, J are smaller in amount of projection from the lower face of the truck compared with other wheels F, E, L, K etc. in consideration of flexure of the truck body 20. Thus, slipping phenomenon of driving wheels is prevented by making the load applied to wheels uniform. |
