A kind of preferred embodiment, as shown in Figs. 1-3, one side of the present embodiment crankcase 400 away from driving motor are equipped with Two-way Swing line oil pump 300, for provide lubricating oil in crankcase.Structure such as Figure 18, Figure 19 of wherein two-way Swing line oil pump 300 It is shown, including the pump housing 310, internal rotor 330, outer rotor 340, the pump cover 320 being fixedly connected with the pump housing and outer rotor positioning disk 350.The center of its middle pump body 310 is equipped with axis hole 312, and the pump shaft being connected with pump housing rotary moveable is equipped in the axis hole 312 360.The pump shaft 360 is connected with bent axle 800 or the part for bent axle 800.Bearing block of the pump housing 310 as crankcase, is used for It is connected with bent axle 800 by bearing.
In the present embodiment, the column deep gouge 311 coaxial with pump shaft 360 is equipped in the one side of the pump housing, the column deep gouge 311 Slot bottom is equipped with oil-feed tank 313 and goes out oil groove 316.It should be noted that fuel feed hole 314 and overflow are wherein equipped in oil-feed tank 313 When fluid in hole 318, wherein oil-feed tank is excessive, flowed out by spout hole.Go out and outage 318 is equipped in oil groove 316, with oil inlet Hole 314 forms oil circulation.In addition, preferably, going out in oil groove to be additionally provided with oilhole 317, lubricating oil can be via the lubrication Oilhole 317 lubricates the other components such as bearing.
As shown in Figure 18, Figure 19, in the present embodiment, internal rotor 330 is located in column deep gouge 311 and is fixed with pump shaft 360 It connects, multiple external toothing teeth is laid on the outer circumferential surface of the internal rotor 330.Outer rotor 340 is located in column deep gouge 311 and covers On internal rotor 330, the inner ring of the outer rotor 340 is laid with multiple internal messing teeth engaged with the matching of external toothing tooth, and The quantity of internal messing tooth is one at least more than the quantity of external toothing tooth.Preferably, in the present embodiment, the quantity ratio of internal messing tooth The quantity of external toothing tooth is one more.
A kind of preferred embodiment, the quantity of the internal messing tooth is 7, and the quantity of the external toothing tooth is 6.
As the improvement of the present embodiment maximum, outer turn is additionally provided between the cell wall of column deep gouge 311 and outer rotor 340 Sub- positioning disk 350.As shown in Figure 22, Figure 23, which is included for the cell wall gap with column deep gouge 311 The outside fix circle 351 of cooperation and for the inside fic circle 352 with 340 clearance fit of outer rotor, and 357 phase of the center of circle of inside fic circle To 356 eccentric setting of the center of circle of outside fix circle.
Position restrainer is rotated in the forward direction it should be noted that being equipped between outer rotor positioning disk 350 and the pump housing 310 or pump cover 320 Structure and reverse rotation position-limit mechanism, and outer rotor positioning disk can between rotating in the forward direction position-limit mechanism and reversely rotating position-limit mechanism It rotates freely.Preferably, outer rotor positioning disk is rotating in the forward direction position-limit mechanism and is reversely rotating the freedom between position-limit mechanism Rotation angle is 180 °.
A kind of preferred embodiment, as shown in Figure 22, Figure 23, the outer rotor positioning disk 350 is set close to the one side of pump cover There is arc groove 353, the pump cover shown in Figure 21 is equipped with and the 353 corresponding positioning pin 370 of arc groove.Wherein arc groove 353 Both ends be respectively for the positive limit end 354 of /V positioning pin and reverse limit end 355, wherein positive limit end 354 with The composition of positioning pin 370 rotates in the forward direction position-limit mechanism, and reverse limit end 355 forms with positioning pin 370 and reversely rotates position-limit mechanism.
It should be noted that above-mentioned is only the preferred embodiment for rotating in the forward direction position-limit mechanism and reversely rotating position-limit mechanism, Not sole limitation.Other equivalent modes should also include:Arc groove is arranged on outer rotor positioning disk close to column sink groove bottom One side, positioning pin be arranged on column deep gouge slot bottom;Arc groove be arranged on column deep gouge slot bottom or pump cover close to column deep gouge One side, positioning pin are arranged on the corresponding side of outer rotor positioning disk;Arc groove is arranged on the cell wall of column deep gouge, and positioning pin is arranged on outer turn In the outside fix circle of sub- positioning disk;Arc groove is arranged in the outside fix circle of outer rotor positioning disk, and positioning pin is arranged on column deep gouge On cell wall, etc. forms.
As shown in figure 21, the pump cover 320 of the present embodiment be equipped with deep gouge 1 corresponding with the oil-feed tank and with it is fuel-displaced The corresponding deep gouge 323 2 of slot, the center of pump cover are equipped with the matched center positioning hole 321 in free end with pump shaft.It is preferably, heavy The shaft end lubrication hole 324 connected with center positioning hole 321 is equipped in slot 1.Lubricating oil in oil suction chamber is lubricated by shaft end Hole is flow between pump shaft and center positioning hole, realizes the shaft end lubrication of pump shaft.The two-way Swing line oil pump of the present embodiment, internal rotor External toothing tooth is six teeth, and the internal messing tooth of outer rotor is seven teeth, and inner and outer Rotator differs a tooth, since inner and outer rotors are multiple tooth nibble It closes, which forms several sealed volumes.When internal rotor is rotated around pump spindle center, drive outer rotor same around outer rotor center To rotation.At this moment, by the annular seal space formed between external toothing tooth tooth top and internal messing tooth tooth paddy, with the rotary seal volume of rotor Just gradually expand, then just form parital vacuum, fluid is inhaled into annular seal space from oil-feed tank.When rotor continues rotation, it is full of The annular seal space of fluid is just gradually reduced, and fluid is squeezed, and is then passed through out oil groove and is discharged oil, internal rotor each rotation, by outer The each annular seal space formed between engaging tooth tooth top and internal messing tooth tooth paddy completes suction, pressure oil respectively once, when internal rotor continuously turns When dynamic, that is, complete the suction oil work of hydraulic pump.
