STEERING DEVICE FOR AN ARTICULATED VEHICLE

摘要

An articulated vehicle, such as a forklift truck, has a steering bogie (14) articulated to the chassis (10) by a substantially vertical shaft (16). A pair of hydraulic steering cylinders (18A, 18B) are coupled to the shaft by means of a pair of chains (24A, 24B) passing around the shaft and terminating at a common link (26) connected to the shaft. By actuating the respective cylinders, the bogie can be turned to the left or right, and the fact that the chains are in non-slip engagement with the shaft means that pulling one or other of the chains causes the shaft to rotate without any significant lost motion or play in the mechanism.
