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.
