Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this.
As shown in Figure 1, a kind of hydraulic sterring engine control system, comprises oil cylinder 1, three-position four-way electromagnetic directional valve 2, buffer 3, accumulator 4, safety valve 5, relief valve 6, one-way valve 7, constant pressure variable displacement pump 8, motor 9, throttle valve 10, filter 11 and fuel tank 12; Described fuel tank 12 is the oil supplying device of whole hydraulic control system; The filler opening of described constant pressure variable displacement pump 8 connects fuel tank 12 by filter 11; Described motor 9 is arranged on constant pressure variable displacement pump 8, for the oil-absorbing process of pump provides power; The oil outlet of described constant pressure variable displacement pump 8 is connected with one-way valve 7 with relief valve 6 simultaneously, and the flow-off of described relief valve 6 is connected with fuel tank 12, thus a composition skimmer circuit; The oil outlet of described one-way valve 7 connects three oil circuits respectively, wherein an oil circuit is connected with accumulator 4, as the auxiliary power source of hydraulic control system, the pressure oil that in short time, supply hydraulic control system is certain, when hydraulic control system breaks down suddenly, still can ensure the oil cylinder safe operation of hydraulic control system, add the Security of system, and accumulator 4 can also reveal the compensation device of loss as hydraulic control system hydraulic oil, thus ensure that the stable of system working pressure preferably; The other end of accumulator 4 is connected with fuel tank 12 by safety valve 5, thus plays the effect of safety protection in whole oil hydraulic circuit.
Another oil circuit of described one-way valve 7 oil outlet is connected with buffer 3, avoids one-way valve 7 to go out the excessive damage to solenoid directional control valve 2 of oil pressure; The Article 3 oil circuit of one-way valve 7 oil outlet is connected with the hydraulic fluid port P of three-position four-way electromagnetic directional valve 2; The hydraulic fluid port P of described three-position four-way electromagnetic directional valve 2 is connected with the oil outlet of one-way valve 7, and hydraulic fluid port O is connected with throttle valve 10; Throttle valve 10 is connected with fuel tank 12 via oil circuit again, composition meter out flow control circuit, is used for regulating the movement velocity of loof mechanism; The hydraulic fluid port A of solenoid directional control valve 2 is connected with the left chamber filler opening of the oil cylinder 1 of steering wheel loof mechanism; Hydraulic fluid port B is connected with the right chamber filler opening of oil cylinder 1.The speed of coming about can be controlled preferably by device of the present invention, make steering wheel Comparision steady, be applicable to very much the servos control of spitkit.
Working procedure is as follows:
When needs steering wheel works, actuating motor 9, constant pressure variable displacement pump 8 is started working.Constant pressure variable displacement pump 8 is by filter 11 suction pressure oil from fuel tank 12, and pressure oil enters in accumulator 4 through one-way valve 7.When three-position four-way electromagnetic directional valve 2 mediates, hydraulic fluid port P, hydraulic fluid port A, hydraulic fluid port B, hydraulic fluid port O are not connected, fluid in the left and right oil cylinder of oil cylinder 1 of loof mechanism is in locking states, steering wheel is stabilized on set rudder angle, because system is without pressure oil, the oil pressure in accumulator 4 raises gradually.When this pressure is elevated to the system nominal working pressure of being set up by relief valve 6, oil spilling opened by relief valve 6, and the oil that constant pressure variable displacement pump 8 is discharged all overflows back fuel tank 12 through this relief valve 6, and system internal pressure no longer raises.When the system pressure drops, relief valve 6 cuts out, and stop oil spilling, constant pressure variable displacement pump 8 recovers again to accumulator 4 and system fuel feeding.
When three-position four-way electromagnetic directional valve 2 left end is energized, the spool of three-position four-way electromagnetic directional valve 2 moves on to left position, hydraulic fluid port P is communicated with hydraulic fluid port O respectively with hydraulic fluid port B, hydraulic fluid port A, pressure oil in accumulator 4 just enters the right oil pocket of loof mechanism oil cylinder 1 through three-position four-way electromagnetic directional valve 2, the fluid of left oil pocket then flows back to fuel tank 12 via three-position four-way electromagnetic directional valve 2 and throttle valve 10, and namely loof mechanism drives rudder blade aport to deflect.
When three-position four-way electromagnetic directional valve 2 right-hand member is energized, the spool of three-position four-way electromagnetic directional valve 2 moves on to right end position, hydraulic fluid port P is communicated with hydraulic fluid port O respectively with hydraulic fluid port A, hydraulic fluid port B, pressure oil in accumulator 4 just enters the left oil pocket of loof mechanism oil cylinder 1 through three-position four-way electromagnetic directional valve 2, and the fluid of right oil pocket flows back to fuel tank 12 via three-position four-way electromagnetic directional valve 2 and throttle valve 10, namely loof mechanism drives rudder blade astarboard to deflect.
When steering wheel goes to the rudder angle of specifying, the power-off simultaneously of three-position four-way electromagnetic directional valve 2 two ends, namely the spool of three-position four-way electromagnetic directional valve 2 gets back to neutral position, and hydraulic fluid port P, hydraulic fluid port A, hydraulic fluid port B, hydraulic fluid port O are not connected, cut off oil circuit, rudder is just stabilized on the rudder angle of requirement.
Because throttle valve 10 is connected in loof mechanism oil circuit, as long as so change the aperture of throttle valve 10, i.e. the adjustable flow by loof mechanism, thus regulate speed of coming about.When throttle valve 10 aperture increases, speed of coming about improves; Otherwise speed of coming about reduces.Because accumulator 4 can provide a large amount of pressure oil to loof mechanism at short notice, therefore improve the speed of coming about, shorten time of rudder movement, meet the needs of coming about.Meanwhile, when constant pressure variable displacement pump 8 breaks down fuel cut-off, accumulator 4 is exportable part fluid still, can maintain steering wheel at short notice and normally run.Accumulator 4 is as Emergency power source, and General Requirements fuel delivery can meet full load, there to be time enough to take emergency measure.When relief valve 6 is malfunctioning; when oil pressure in accumulator 4 is increased to the system nominal working pressure of being set up by relief valve 6; safety valve 5 will be unlocked; the fluid that constant pressure variable displacement pump 8 enters accumulator 4 flows back to fuel tank 12 through safety valve 5; thus the oil pressure in anti-locking system continues to raise, and plays the effect of safety protection.
Described embodiment is preferred embodiment of the present invention; but the present invention is not limited to above-mentioned mode of execution; when not deviating from flesh and blood of the present invention, any apparent improvement that those skilled in the art can make, replacement or modification all belong to protection scope of the present invention.
