Abstract

Control procedure of hydraulic drag engines mounted on one or more axes of a motor vehicle, such as a tractor or a public works apparatus, of the type in which said motors are fed with hydraulic fluid to drive in rotation the or axes on which they are mounted when said vehicle must provide a high traction or thrust force at low speed, characterized in that said motors are fed by a total flow of hydraulic fluid at a total pressure that is a function of the sum of the pairs applied to said motors, and said fluid is distributed between said motors in such a way that each motor is fed by a fluid flow equal to a substantially constant fraction of the total flow, with a hydraulic pressure that is a function of the torque of said motor, being the total feeding pressure is substantially zero when the sum of the pairs of the motors is close to zero, the positive power supply of a motor while a torque is applied to said motor and canceling when said torque is substantially zero.
