Abstract
PURPOSE:To enable quick turning operation by providing a pair of right and left front wheel brakes for supplying braking force to the respective right and left front wheels independently and controlling in such a manner that when a steering angle exceeds a preset value, the front wheel brake on the steering direction side is operated. CONSTITUTION:There is provided a volume VR for detecting the steering amount of a handle 5, and the output data is always checked by CPU 21. When a handle 5 is, for example, operated to the right side and the output of the volume VR gets a positive value, a solenoid SOL 3 of a directional control valve 12 is driven, so that steering of the opposite phase to that of front wheels 4a, 4b is applied to rear wheels 7a, 7b by a power cylinder 8 for rear wheels. After that, it is checked whether the value of the volume VR is within a designated value + or -K, and if it is not within the range, the output value of the volume VR is judged to be positive or negative, and a directional control valve 10a or 10b is controlled to supply pressure oil to a front wheel brake 1a or 1b on the inside in the turning direction.
