Title:
WHEEL STEERING GEAR FOR TRACTOR-DRAWN FARM WORKING MACHINE
Document Type and Number:
Japanese Patent JPS621676
Kind Code:
A
Abstract:
PURPOSE:To make a wheel turnabout automatically performable accurately and surely with a pushbutton pressed only one time, by installing three-spot lock grooves for straight, right-turn and left-turn use in the slide rod pivotally attached to a turnabout shaft. CONSTITUTION:One end of a slide rod 23 is pivotally attached to a turnabout shaft, while lock grooves 24-26 for straight, right-turn and left-turn use are installed in three spots of the slide rod 23 at regular intervals, covering them with a dustproof case 27. And, a limit switch 10 attached to the center of this case 27, and a roller 28 is attached to an on-off contact point, and when this roller 28 is fitted in any of these lock grooves 24-26, the limit switch is formed so as to open. One end part of a hydraulic cylinder 14 is pivotally attached to the turnabout shaft, interlocking it with the slide rod 23. If a pushbutton is pressed, the roller 28 shifts to a rod large diametral part and keep on with operation till the next lock groove comes. Therefore, there is unnecessary to continue to press the pushbutton, thus an accurate turnabout is performable.
