Abstract

A hydraulically driven traveling vehicle comprising a pair of right and left driving axles (driving sprockets) differentially connected to each other by a differential mechanism, the input section of the differential mechanism having the output rotation of traveling HST 110 (110) transmitted thereto, both driving sprockets having mutually opposite two-flow output rotations separately transmitted thereto from a steering HST (120), thereby effecting traveling driving and turning, electromagnetic solenoids (61a, 61b, 62a, 62b) serving as output regulating means for the traveling HST and the steering HST being provided so that the manipulated variables and directions of a speed change lever and a steering operation tool are converted into electric signals, on the basis of which electric signals the output current values of the electromagnetic solenoids are controlled, causing the respective output rotary speeds of the HSTs to correspond to the output current values, wherein the respective output current values of the electromagnetic solenoids (61a, 61b) of the traveling HST and the electromagnetic solenoids (62a, 62b) of the steering HST are controlled on the basis of both the electric signal resulting from the operation of the speed change operation tool and the electric signal resulting from the operation of the steering operation tool. <IMAGE>
