Abstract: PURPOSE: To raise the transmission efficiency of an oil-hydraulic driving device and eliminate a quiver at a neutral mode by a method wherein an oil-hydraulic pump of fixed capacity type is connected with each of oil-hydraulic motors of fixed capacity type connected with right and left wheels through the intermediary of oil-route switching valves of high speed responsiveness.  
     CONSTITUTION: An oil-hydraulic pump P of fixed capacity type is driven by an engine E and is connected with electromagnetic 3-position switching valves 1l and 1r. Right and left oil-hydraulic driving motors Ml and Mr are the oil-hydraulic motors of fixed capacity type which obtain the driving force by being connected directly with wheels and are joined to the electromagnetic 3-position switching valves 1l and 1r, respectively. A signal from a steering wheel 3 and a speed-change lever 5 is guided by a controller 7 to control a pulse generator 8, thus driving the electromagnetic 3-position switching valves. Since the oil-hydraulic pump P of fixed capacity type is used as in the above, the transmission efficiency is raised and thus a quiver at a neutral mode can be eliminated.

In other words, the value of the closed loop time constant becomes smaller when the value of the error signal Ei is large and the value of the closed loop time constant becomes larger when the value of the error signal Ei is comparatively small.  Moreover, the relation between the error signal and the closed loop time constant can be expressed by a reverse relation in which the closed loop time constant is an inverse relation to the system error.
