The permanent magnet 26 of annular is set in the outer ring of cylinder body 23, the outside that is enclosed in cylinder body 23 of motor stator 27 concentrics of annular, promptly motor stator 27 concentrics surround permanent magnet 26, this motor stator 27 is fixedly linked with the inner surface of electric machine casing 25; Stator winding 28 is embedded in the motor stator 27.
Be provided with speed probe 3 in the inner chamber of left end cap 1, this speed probe 3 is fixedly set in the outer surface of rotating shaft 24, and promptly speed probe 3 is along with rotating shaft 24 rotates together; The lead of speed probe 3 and stator winding 28 is introduced into respectively in the terminal box 5.
Logical oily joint piece 16 is fixedly linked with right end cap 17, and logical oily joint piece 16 is provided with oil-in 15a and oil-out 15b.Oil-in 15a on the logical oily joint piece 16, the oil inlet passage in the right end cap 17 and the oil-feed window on the oil distribution casing 20 are connected successively, and the oil-out 15b on the logical oily joint piece 16, the oil discharge passage in the right end cap 17 and the fuel-displaced window on the oil distribution casing 20 are connected successively.In cylinder body 23 rotation processes, in 9 plunger holes 32, have 4 or 5 plunger holes 32 to be connected with oil-feed window on the oil distribution casing 20, remaining plunger hole 32 is connected with fuel-displaced window on the oil distribution casing 20.The plunger hole 32 that is connected with oil-feed window on the oil distribution casing 20 is called the high pressure chest plunger hole, and the plunger hole 32 that is connected with fuel-displaced window on the oil distribution casing 20 is called the low-pressure cavity plunger hole.
The magneto alternator that integrated hydraulic of the present invention drives is arranged on permanent magnet 26 on the cylinder body 23 along with rotating shaft 24 together rotate, thus the rotor of formation generator.
The magneto alternator operation principle that integrated hydraulic of the present invention drives is as follows:
On the one hand, after the oil-in 15a on the logical oily joint piece 16 connected high-voltage oil liquid, fluid entered the oil-feed window of oil distribution casing 20 through the oil-in 15a of logical oily joint piece 16, the oil inlet passage of right end cap 17 successively, flows into the high pressure chest plunger hole of cylinder body 23 then again; Because the effect of hydraulic oil makes that the plunger 8 in the high pressure chest plunger hole is ejected (promptly the inclined-plane 35 towards swash plate 31 moves).On the other hand, the plunger 8 in the low-pressure cavity plunger hole is contracted, and low pressure fluid is successively through the oil return window of valve plate 20, the oil discharge passage of right end cap 17, the oil-out 15b oil return of logical oily joint piece 16.The fluid of every plunger hole 32 periodically switches in high pressure chest, low-pressure cavity, thus the process of the oil-feed of execution cycle property, oil return.
Because the effect of high-low pressure fluid, the reaction force of 31 pairs of cylinder bodies 23 of swash plate forms unbalanced driving moment, drives cylinder body 23 rotations.In the rotary movement, piston shoes 6 are done the slip of elliptical orbit on the inclined-plane 35 of swash plate 31, and plunger 8 is done straight reciprocating motion with respect to cylinder body 23 in plunger hole 32, when in the plunger hole 32 during logical hydraulic oil, and plunger 8 outwards move (being ejected); When in the plunger hole 32 during logical low pressure oil, plunger 8 move inwards (being contracted).Be embedded with permanent magnet 26 on the cylinder body 23, constitute the rotor of generator, after the rotor rotation, according to electromagnetic induction principle, in the stator winding 28 of motor stator 27, will produce induced electromotive force, produce induced current after linking to each other with load by terminal box 5, thereby realize the direct conversion that hydraulic pressure can arrive electric energy.Speed probe 3 is used to detect the rotary speed of rotor, thereby can realize the closed-loop control of rotating speed, and then accurately controls flow.
In running, plunger 8 and plunger hole 32, the inclined-plane 35 of piston shoes 6 and swash plate 31, there is leakage inevitably in friction pair between cylinder body 23 and the valve plate 20, for fear of electric machine casing 25 inner fluid hypertonia, need in time the fluid that leaks to be discharged outside the electric machine casing 25, drain tap 14 promptly is used for discharging and leaks fluid.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
