In a drive arrangement for driving a fork lift truck with a primary energy source (1) whose adjusting member (46) is connected to the output (45) of an electronic controller (44), and a hydrostatic transmission (3, 4, 5, 6, 7) and a pump (60) for charging consumers with hydraulic energy, a deliberately actuatable valve (12) is connected between the pump (60) and the consumer, the switching travel of which valve is a signal for the setpoint of the flow through said valve (12). The controller (44) is supplied with signals for the set-point of the transmission output speed, for the actual value of the primary energy source speed and for the valve switching travel. Flow through the valve (12) is controlled by a flow divider throttle valve (67) which throttles in the driven state and a pressure limiting valve (70) protects the line (66) between the pump (60) and the valve (67). A pump (62) controls the steering (65) and a pump (61) controls the actuating device (30-33) for the pump (3) and is connected to a pressure limiting valve (69). <IMAGE> |
