Left end cap 1, right end cap 17 are fixedly linked by screw 3 and housing 18, at left end cap 1, arrange seal ring 14 between right end cap 17 and housing 18.Oil inlet passage and oil discharge passage is respectively equipped with in right end cap 17.In left end cap 1, be provided with left bearing 2, in right end cap 17, be provided with right bearing 15, the left end running through the running shaft 24 of housing 18 is connected with left bearing 2, right-hand member is connected with right bearing 15; The shaft axis of running shaft 24 and the shaft axis of housing 18 overlap.
In housing 18, be provided with the cylinder body 25 in hollow cylindrical, this cylinder body 25 is sleeved on the outer surface of running shaft 24, and cylinder body 25 and running shaft 24 are fixedly linked by spline; The inner ring of cylinder body 25 and the outer surface of running shaft 24 keep certain gap.Arrange swash plate 28 in the left side of cylinder body 25, this swash plate 28 is fixedly linked by pin 4 and left end cap 1; Arrange thrust plate 19 on the right side of cylinder body 25, this thrust plate 19 is fixedly linked by pin 13 and right end cap 17, and the right side of cylinder body 25 is close to by thrust plate 19.Thrust plate 19 is respectively equipped with oil-feed window and oil return window.
The plunger hole that 7 axis run through cylinder body 25 is evenly set in cylinder body 25, in each plunger hole, is equipped with a plunger 8 that can horizontally slip along plunger hole internal surface.The permanent magnet 9 of hollow cylindrical is set in each plunger.The spherical head of each plunger 8 is hinged with the spherical recess on corresponding piston shoes 6, uniform 7 circular holes on return plate 27, and therefore the upper end of each piston shoes 6 is all sleeved in the circular hole of return plate 27, thus piston shoes 6 and return plate 27 are fixedly linked.Ball pivot 26 with the form of mating spherical surfaces and return plate 27 hinged.Therefore, cylinder body 25 side and thrust plate 19 are tightly affixed, and opposite side is affixed by the cooperation of plunger 8, piston shoes 6, ball pivot 26, return plate 27 and swash plate 28.
The push rod 22 (6 shown in such as Fig. 2) of spring seat 10, back-up ring 20, retracting spring 21 and some is set in the gap that the inner ring of cylinder body 25 and the outer surface of running shaft 24 are formed.Back-up ring 20 near cylinder body 25 right side is fixedly linked with cylinder body 25, and the right-hand member of retracting spring 21 is by packing ring 11 against back-up ring 20, and the left end of retracting spring 21 arranges spring seat 10, and the two ends of every root push rod 22 are respectively against spring seat 10 and ball pivot 26.Retracting spring 21 is fixed into compressive state by spring seat 10 and back-up ring 20, thus makes cylinder body 25 compress thrust plate 19 on the one hand, makes piston shoes 6 be close to the inclined-plane of swash plate 28 successively on the other hand by push rod 22, ball pivot 26 and return plate 27.
Be fixedly installed coil 23 at the internal surface of housing 18, this coil 23 is enclosed in the outside of cylinder body 25.The wire of coil 23 is introduced in terminal box 5.
Logical oily joint 16 is fixedly linked with right end cap 17, and logical oily joint 16 is provided with filler opening and oil outlet.Filler opening on logical oily joint 16, the oil inlet passage in right end cap 17 are connected successively with the oil-feed window on thrust plate 19, and the oil outlet on logical oily joint 16, the oil discharge passage in right end cap 17 are connected successively with the fuel-displaced window on thrust plate 19.
Plunger hydraulic energy recycle device working principle of the present invention is as follows:
After the filler opening on logical oily joint 16 connects high-voltage oil liquid, fluid is successively through the oil-feed window leading to the filler opening of oily joint 16, the oil inlet passage of right end cap 17 enters thrust plate 19, then the partial plunger hole of cylinder body 25 is flowed into again, this partial plunger hole is called hyperbaric chamber plunger hole, and all the other plunger holes are called low-pressure cavity plunger hole; Due to the effect of high-voltage oil liquid, the plunger 8 in hyperbaric chamber plunger hole is ejected.Meanwhile, the plunger 8 in low-pressure cavity plunger hole is contracted, and low pressure fluid is successively through the oil discharge passage of the oil return window of thrust plate 19, right end cap 17, the oil outlet oil return of leading to oily joint 16.Due to the effect of high low pressure fluid, the reaction force of swash plate 28 pairs of cylinder bodies 25 forms unbalanced driving moment, drives cylinder body 25 to rotate.In cylinder body 25 rotary course, the fluid of every plunger hole periodically switches in hyperbaric chamber, low-pressure cavity, thus the process of the oil-feed of execution cycle property, oil return.
In running, plunger 8 does straight reciprocating motion relative to cylinder body 25 in plunger hole, and when leading to high pressure oil in plunger hole, plunger 8 outwards moves (being ejected); When leading to low pressure oil in plunger hole, plunger 8 moves (being contracted) inwards.Plunger 8 is embedded with permanent magnet 9, this permanent magnet 9 does identical straight reciprocating motion with plunger 8, according to electromagnetic induction principle, will produce induction electromotive force in coil 23, produce induction current after being connected with load by terminal box 5, thus realize the direct conversion of hydraulic energy to electric energy.
In running, plunger 8 and plunger hole, the inclined-plane of piston shoes 6 and swash plate 28, inevitably there is leakage in the friction pair between cylinder body 25 and thrust plate 19, in order to avoid housing 18 inner fluid overpressure, need to be discharged outside housing 18 by the fluid leaked in time, drain tap 12 is namely for discharging leakage fluid.
Finally, it is also to be noted that what enumerate above is only a specific embodiment of the present invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be had.All distortion that those of ordinary skill in the art can directly derive from content disclosed by the invention or associate, all should think protection scope of the present invention.
