Document Type and Number:
Japanese Patent JPS6441480
Kind Code:
A
Abstract:
PURPOSE:To improve the steering performance for a tractor and a trailer by operating a driving means for controlling an arm member for connecting a tractor and a trailer when the relative angle between the tractor and the trailer becomes equal to a previously set value in turning operation. CONSTITUTION:A steering device 20 is equipped with a driving motor 28 for driving a hitch member 22 so as to swing around a supporting shaft and a lid motor 40 for opening/closing-operating a lid for opening and closing an accommodation part. The both motors 28 and 40 are controlled by a controller 41, which receives the signals supplied from a detecting means 43 for detecting the steering angle of the front wheel of a tractor, can speed detecting means 42, relative angle detecting means 44 for detecting the relative angle between the tractor and the trailer, and a turning angle detecting means 45 for a hitch member for the center line in the longitudinal direction of the tractor. The motor 28 is driven by the signal supplied from the controller 41, and the optimum steering state can be obtained.
