Title:
INPUT TORQUE CONTROLLER FOR VARIABLE CAPACITY HYDRAULIC CONDUCTION EQUIPMENT
Document Type and Number:
Japanese Patent JPS5822420
Kind Code:
A
Abstract:
A torque control for a drive system having a hydraulic transmission connectable to a prime mover (30) and having a pair of hydraulically-connected displacement devices V and F, with one device having variable displacement, a torque sensor (35) generates a torque signal representative of prime mover output torque in either driving or braking mode, torque demand generators (47,47') generate a torque demand signal selectively in either driving or braking modes, a governor valve (63) compares the torque signals and generates a control signal and a control servo 17, responsive to the control signal, controls the displacement of the variable displacement device V to eliminate any difference in torque signals.
