Abstract:
PROBLEM TO BE SOLVED: To solve problems such as the complication of steering operation during turning and an unpleasant feeling in turning operation and low accuracy in turning since a traveling hydraulic continuously variable transmission and a turning hydraulic continuously variable transmission are heretofore individually controlled in a crawler type traveling vehicle provided with the conventional traveling hydraulic continuously variable transmission and turning hydraulic continuously variable transmission. SOLUTION: A traveling HST 110 and a turning HST 120 are additionally provided with proportional solenoid valves 61, 62, and the output rotating speed of the traveling HST 110 and that of the turning HST 120 are controlled interlockingly with the magnitude of a steering wheel operating angle and a main shift lever operating angle.
