Wheel equipment of transportation vehicle

Abstract

Abstract PURPOSE:To get rid of any slippage of wheel, when a vehicle is steered, on the floor face for the purpose of minimizing creation of wheel dust resulting from wear by specifically determining the mutual relation among the clearance distance measured between the wheel and the axis of a steering shaft, the radius of the wheel and the reduction ratio of a reduction gear. CONSTITUTION:A steering shaft 3 is vertically attached via a bearing 2 to a fitting base 2 which is the lower part of a vehicle body. A wheel shaft 4 is also attached via another bearing to the steering shaft 3 at right angles with the center axis A thereof and a wheel 5 having a radius R is disposed apart by the distance L from the center axis A. A reduction gear 7 which turns a driving shaft 6 is mounted on the base 1. The relation among reduction ratio between the gears 8 and 9 of the reduction gear 7, the distance L and the radius R are determined to be NL=R. Since the wheel 5 mav roll on the floor face without any slippage thereon when the wheel vehicle is steered, creation of dust resulting from wear of the wheel may be restrained to a minimum. Application of a transportation vehicle in the field of a very large scale integration factory which disgust any creation of dust and dirt will offer a materially effective result.
