Title:
HYDRAULICALLY DRIVEN TRAVELING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2001/056864
Kind Code:
A1
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) transmitted thereto, both driving sprockets having mutually opposite two-flow output rotations separately transmitted thereto from a revolving HST (120), thereby effecting travel driving and revolving, electromagnetic solenoids (61a, 61b, 62a, 62b) serving as output regulating means for the traveling HST and revolving HST being provided so that the manipulated variables and directions of a speed change lever and a revolution operating 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 revolving HST are controlled on the basis of both the electric signal resulting from the operation of the speed change operating tool and the electric signal resulting from the operation of the revolution operating tool.
