Title:
STEERING DEVICE OF TRACTOR
Document Type and Number:
Japanese Patent JP3900638
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To quickly change a steering device according to a work condition and a travel condition, and make a safe turn by precise steering operation by arranging a setting unit to change/adjust a steering angle of steering to a constant reference value in a power steering.
SOLUTION: A setting unit to set a reference value of a control start angle is composed of a setting dial to change/adjust this reference value in control to increase a steering angle of front wheels 1 by a power steering 37 when a steering angle of a steering wheel 7 reaches the reference value. An adjusting quantity by this setting dial is renewed by being inputted to a controller by a potentiometer to be set as the reference value. When the reference value is changed, the reference value by the setting unit is enlarged, and a steering angle of steering S reaching the reference value is enlarged. The reference value is reduced, a steering angle of the steering S is reduced, and a steering speed of the front wheels 1 is increased to make steering sensitive, so that a safe turn can be made.
