Fluid pump control device for wheel loaders
A fluid pump control device for wheel loaders includes an engine (8) for driving an axle through a transmission (9), a main pump (P1), a variable-displacement steering pump (P2) with a pump regulator (14), an auxiliary pump (P3), an electronic proportional control valve (17) provided on a discharge quantity control signal line (16) leading to the pump regulator (14) for variably controlling a pilot pressure (19) conveyed to the pump regulator (14), a hydraulic load detector (4) for detecting a real hydraulic load (Px), an engine revolution detector (10) for detecting the number of revolution (N1) of the engine (8), a transmission revolution detector (11) for detecting the number of output shaft revolution (N2) of the transmission (9). A controller (20) is adapted to control the electronic proportional control valve (17) and hence the fluid discharge quantity of the steering pump (P2), based on the real hydraulic load (Px), the number of revolution (N1) of the engine (8) and the number of output shaft revolution (N2) of the transmission (9).
