HYDRAULIC TRAVELING VEHICLE

摘要

A hydraulic traveling vehicle where, when it turns quickly and slowly, deficiency of the traveling speed in the turning and loss of hydraulic pressure are prevented. In the hydraulic traveling vehicle, a hydraulic pump section (17) has a first pressurized oil supply port (25) for supplying pressurized oil to a first hydraulic circuit (20) and a second pressurized oil supply port (26) for supplying pressurized oil to a second hydraulic circuit (21).A flow converging/dividing valve (23) switches over between the convergence and division of the first hydraulic circuit (20) and the second hydraulic circuit (21). A controller (66) can switch over the flow converging/dividing valve (23) between a converged flow state and a divided flow state. In the converged flow state, the vehicle turns quickly where either a right travel motor (18) or a left travel motor (19) is stopped and the other is driven. In the divided flow state, the vehicle turns slowly where the right travel motor (18) and the left travel motor (19) are driven at different rotation speeds.
