Abstract:
A hydraulic circuit for traveling comprising:a hydraulic pump; two hydraulic motors for driving and rotating traveling wheels, respectively; a pumping passage for supplying a high pressure fluid discharged from the hydraulic pump to the two hydraulic motors, the pumping passage including one end connected to said hydraulic pump and bifurcated halfway, other ends of the pumping passage being connected to the hydraulic motors, respectively; two rotation detectors for detecting rotational speeds of the hydraulic motors, respectively; a detection controller for detecting whether or not any traveling wheel is skidding by comparing the rotational speeds detected by the rotation detectors; and two braking force applying members for applying a braking force only to the hydraulic motor of the skidding traveling wheel on the basis of the result of detection from the detection controller, the braking force applying members being installed in each of the hydraulic motors.
