Title:
STEERING DEVICE FOR COUPLED VEHICLE
Document Type and Number:
Japanese Patent JPS6432976
Kind Code:
A
Abstract:
PURPOSE:To improve the turning operability by three-point supporting a wheel hub on a wheel support member, forming the king-pin center line by a line connecting two supporting points on the front side of a car body, and turning the other two supporting point centering round one supporting point as designated. CONSTITUTION:When a traction vehicle is turned, lateral force is applied to a wheel 1, and a wheel hub 3 is turned in the opposite direction to the turning direction centering round the king-pin central axis P regulated by the first and second supporting points A, B. Whereupon, at a supporting point C, the forward end 33A is slid in a groove 53 in the direction of width of a car. As a result, the wheel 1 gets tow change corresponding to circular-ac angles alpha, betainward and outward from the center of the groove 53 in the direction of width of the car. On the other hand, in case of rectilinear motion, the wheel hub 3 is turned backward centering round the supporting point A, and the forward ends 32A, 33A are slid backward in the grooves 52, 53 to offset a king-pin zero. Thus, the turning operation can be facilitated.
