Title: Turning control device for tractor
Inventor: KANEFUJI YUJI
IPC: B60W10/11
Filed: 2000-01-06
Abstract: PROBLEM TO BE SOLVED: To simplify and facilitate turning operation by changing a high-low speed selecting device for changing a front wheel driving state over to high-low speed and a neutral state, from the low speed side to the high speed side, and braking a rear wheel braking device on the turning inside upon the detection of a steering angle detecting device. SOLUTION: When a detected steering angle detected by a steering sensor is in a range of θ1, a front wheel clutch is held to neutral, and only a rear wheel is driven to travel. When the detected steering angle is in a range of θ1 to θ2, the clutch is put into low speed. A rotation ratio of a front wheel to the rear wheel at this time is R1:R2, and the front wheel is rotated at slightly higher speed than the rear wheel. θ3 is a steering angle when turning with a minimum turning radius. When the detected steering angle gets close to θ3, a braking device on the turning inside of the rear wheel is actuated, and a brake on that side is applied to assist a sharp turn.
