<p><P>PROBLEM TO BE SOLVED: To provide a steering device of a guide rail type vehicle capable of performing the active steering of a wheel and continuing the operation even when a steering actuator is inoperative. <P>SOLUTION: A wheel 5 is steered in the right-to-left direction according to the turn in the right-to-left direction of a guide arm 4 for performing the guide along a guide rail. A restoration damper 14 for demonstrating the force for returning the wheel 5 in the straight posture and a steering actuator 17 capable of nullifying the control force of an operation rod 17a are interposed in parallel between a knuckle arm 13 fitted to the guide arm 4 and a truck frame 8 forming a fixed part on a vehicle body 1 side. Normally, the wheel 5 is steered in the right-to-left direction via the knuckle arm 13 and the guide arm 4 through the expansion operation of the steering actuator 17. If the steering actuator is uncontrollable, the passive steering of the wheel 5 is performed based on the guide of the guide arm 4 along the guide rail by nullifying the control force of the operation rod 17a. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
