Abstract
A drive mechanism is disclosed which includes a hydraulic pump whereby at least two hydraulic motors may be supplied with pressure medium. The drive mechanism in accordance with the invention has on the meter-in side or on the meter-out side of each hydraulic motor a variable hydraulic resistor that is biased into a basic position of minimum open cross-section and may be subjected to a control pressure in a direction of increased open cross-section. This control pressure is dependent on the pressure on the meter-in side or on the meter-out side of the hydraulic motor.
