Title:
FLUCTUATION CONTROL DEVICE OF INDUSTRIAL VEHICLE
Document Type and Number:
Japanese Patent JP3721704
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fluctuation control device of an industorial vehicle which can avoid a running impossible condition in a low speed turning time securely, without sacrificing the running stability of the vehicle.
SOLUTION: A rear axle 10 to support rear wheels is provided allowable to fluctuate to a car body frame by making a center pin 10a as the center, and it is connected to the car body frame by its end through a damper 13. A controller 25 calculates a lateral force G operating to the car body, from a tire angle θ and a car speed V detected by a tire angle sensor 21 and a car speed sensor 22, and when the lateral force G is made more than a specific value, a solenoid change-over valve 14 is converted to lock the damper 13. The controller 25 releases the locking of the rear axle 10 even though the lateral force G is more than the set value, when the car speed V is less than the value corresponding to the idle rotation time of an engine.
