PURPOSE:To achieve Ackermann steering in all of the running conditions by carrying out steering by using an angle formed between an axis connecting a turning center to each steering center of right and left load wheels, and an axis on which the turning centers before they are rotated and moved, fall, as a steering angle of each of the right and left load wheels. CONSTITUTION:An axis G on which turning centers passing steering centers M, N, fall, is assumed for right and left load wheels 12R, 12L supported by a reach-type forklift 1 so that they can be steered. An axis D, on which turning centers after the axis G is turned and moved around a steering center O of a drive wheel 11, by a designated advance angle theta0, fall, is assumed. An intersect formed between the axis D and an axis F drawn from the steering center O along a steering angle theta1 of the drive wheel 11, is defined as a turning center P. Each axis H, I connecting the turning center P to each of the steering centers M, N, is determined, while steering is carried out by using each angle thetaL, thetaR formed between the respective axes H, I and the axis G, as steering angles of the right and left load wheels 12R, 12L. |
