Embodiment
Referring to Fig. 1, Fig. 2, be used for the closed type hydraulic system of the stepless double-current steering equipment of light-duty all-terrain vehicle, its hydraulic oil container 5 is communicated with oil hydraulic pump 8 by oil outlet tube 6, is communicated with by first high-pressure oil pipe 9 and second high-pressure oil pipe 11 between oil hydraulic pump and the oil hydraulic motor 10; Oil hydraulic motor is flowed to the 3rd low pressure return tube 4 by the first low pressure return tube 12, oil hydraulic pump by the second low pressure return tube 7 and is communicated with filter cleaner 3, filter cleaner 3 is communicated with hydraulic oil radiator 13 by radiator oil inlet pipe 1, and hydraulic oil radiator is communicated with hydraulic oil container 5 by radiator oil outlet tube 2.The aperture Control Shaft 8-1 of oil hydraulic pump 8 is connected with the steering shaft 15 of light-duty all-terrain vehicle by turning to drag-line 14, is controlled by steering wheel; The power input splined shaft 8-2 of oil hydraulic pump 8 is connected with gearbox 18 by counter drive shaft 20; The power output spline 10-1 of oil hydraulic motor 10 is 21 by sprocket driving and turns to transmission case 16 to be connected.
Two pressure ducts are set between oil hydraulic pump and the oil hydraulic motor, and hydraulic oil is flow at high speed therein.During left steering, first high-pressure oil pipe is the in-line of oil hydraulic motor, and second high-pressure oil pipe is the fuel-displaced pipeline of oil hydraulic motor; During right steering, second high-pressure oil pipe is the in-line of oil hydraulic motor, and first high-pressure oil pipe is the fuel-displaced pipeline of oil hydraulic motor.Hydraulic oil has leakage when oil hydraulic motor and hydraulic pump works, the hydraulic oil of leakage by the first low pressure return tube and the second low pressure return tube be flowed to behind the 3rd low pressure return tube after filtration, heat radiation finally flows back to hydraulic oil container; Simultaneously, the oil in the hydraulic oil container flows to oil hydraulic pump again, the leakage part in compensated pump and the motor, unnecessary oil constantly washes away the housing of pump in pump, with the pump cooling, thus the hydraulic oil that flows in the cooling pressure duct, and last unnecessary oil also flows back to fuel tank through return line.
This hydraulic system car load is arranged as shown in Figure 3.When turning to, the power of motor 17 is divided into two groups, and one group passes to by gearbox 18, main drive shaft 19 and to turn to transmission case 16; One group is 21 to pass to and turn to transmission case by gearbox, counter drive shaft 20, oil hydraulic pump 8, oil pipe, oil hydraulic motor 10, sprocket driving.After turning to transmission case that two groups of power are converged, will make two output shafts that speed difference is arranged, thereby realize continuous turning.The main effect of oil hydraulic pump is to turning to transmission case that the second tunnel power circuit is provided, have only in the time of Vehicular turn in the system, and oil hydraulic pump is transmitted power, is idle running during straight-line travelling.Oil hydraulic pump is directly with turning to drag-line to be connected with steering shaft.When turning to, turn to drag-line to drive hydraulic pump works, hydraulic oil flows in the pressure duct high speed, oil hydraulic motor is worked under the pressure of hydraulic oil, the straight line motion of its inner oil cylinder is converted to rotatablely moving of main shaft, the output high pulling torque, thus realize that car load turns to flexibly.
