The utility model solves the defect existed in background technique, and the utility model possesses following beneficial effect:
(1) by the action of toggle mechanism, actuation gear can be shifted one's position between the first gear and the second gear, serve the effect of conversion actuation gear engagement object, simultaneously because the first gear is contrary with the second gear sense of rotation, ensure that each actuation gear conversion engagement object rear drive shaft all converts sense of rotation.
(2) sense of rotation of live axle and the direction of stirring of toggle mechanism form linkage structure just, when actuation gear and the first gears meshing, toggle mechanism driven shaft drives the tendency and power that toggle mechanism are had actuation gear is allocated to the second gear, and final actuation gear departs from the first gear, and the elastic potential energy of the first spring on fork is relied on to drive and the second gears meshing; Otherwise when actuation gear and the second gears meshing, toggle mechanism can make actuation gear reversing motion.
(3) structure of feather key can ensure that the clip existed between actuation gear and live axle along live axle circumference limits on the one hand, ensure actuation gear can not circumferentially with live axle generation relative movement, on the other hand actuation gear can sliding axially along live axle, ensures that actuation gear moves between the first gear and the second gear.
(4) two shifting fork bars lay respectively at actuation gear both sides, actuation gear can driving lever drive under, along live axle axial motion.
(5) athletic posture that block can limit driving lever is overlapped, the fork that first spring drives can be limited in certain hunting range by block simultaneously, and then the range of movement of driving lever is also defined, ensure the left and right skew that driving lever can not be excessive, only ensure that actuation gear converts the spacing of engagement between the first gear and the second gear.
(6) when actuation gear and the first gears meshing, fork offsets towards the first gear side, now the first spring straining fork, swivel nut by bolt rod driving away from the first gear, then first the first tightrope is tauted, and then pull fork to rotate towards the second gear side, when fork crosses vertical state, actuation gear and the first gear depart from, now fork just can pull and support towards the second gear side by the pulling force of the first spring, and fork is swung towards the second gear direction, actuation gear presses and the second gears meshing the most at last.
(7) shifting fork bar is constantly moved left and right along live axle by two shifting fork bars promotion actuation gears in the side-to-side movement process of driving lever, change engagement object.
Cooperatively interacting of (8) first rotating shafts and the second rotating shaft, makes fork with the second rotating shaft for rotating in the center of circle, to drive driving lever to move left and right, and then shift fork bar is followed driving lever and moved left and right.
(9) two pulleys are arranged on the left and right sides of the second rotating shaft, and the second tightrope is by after the company's of walking around pulley, and the second tightrope of transformation pulls the direction of fork, ensures that two tightropes can pull fork respectively from different directions.
(10) move left and right in process at knee, the first tightrope and the second tightrope can realize nonsynchronous preferential tensioned state, fork is achieved situation that the same time only can be tightened by a tightrope.
(11) arranging of block ensures that the lower end of fork can not be departed from and overruns, and also namely fork can not make driving lever moving range excessive.
(12) structure of bolt rod driving swivel nut, and then swivel nut provides power resources for toggle mechanism, because the sense of rotation of screw rod is relevant with the object that actuation gear engages, so, the moving direction of swivel nut is relevant with the sense of rotation of live axle, and the sense of rotation of live axle is subject to the control of toggle mechanism; Such said process just forms interactional cyclic motion process, and toggle mechanism and driving mechanism constantly affect continuous loop control.
(13) when actuation gear and the first gears meshing, rolling wheel near the second gear side just tightens up the tightrope of its correspondence, after tightrope is tightened to certain energy degree, fork just pulls by tightrope, shifting fork bar motion now on driving lever, actuation gear promotes to the second gear direction by shifting fork bar, and finally makes actuation gear and the second gears meshing, and live axle is reversed; Otherwise actuation gear is pulled to the first gear direction and engages.
Spacing between (14) two shifting fork bars is greater than the axial length of actuation gear, provides heterodromous inertia to cushion can to the motion of actuation gear.
Spacing between (15) two shifting fork bars is greater than the axial length of actuation gear, the length of being longer than actuation gear is the length surpluses of two shifting fork bar spacing relative to actuation gear, due to the existence of above-mentioned surplus, fork is when being in vertical state, two shifting fork bars all can not stop by actuation gear, only need when fork crosses its vertical state to rely on inertia.
(16) driving gear is coaxial with the first gear, and the second gear engages with driving gear, achieves the counterrotating of the first gear and the second gear.
(17) locking lever on shut-down mechanism can pull up by handle, and being stopped the projection that the right-angle surface in mechanism blocks like this can depart from constraint, and driving lever just can continue to move left and right, only otherwise pulling up mechanism just only can do monocyclic motion.
(18) projection can be blocked in the position of actuation gear just between the first gear and the second gear by the position that shut-down mechanism is arranged, and now actuation gear departs from engagement.
