For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As Fig. 1-shown in Figure 5: the sprocket wheel of power resources is fixed in the groove of four paws sleeve 4, four paws sleeve 4 is supported on the hollow shaft 1 by A bearing 2, four paws sleeve 4 can be stirred cross shift fork 6, between four paws sleeve 4 and the internal clickwork circle 9 C bearing 5 is arranged, internal clickwork circle 9 usefulness screw threads are fixed on an end of shell 10, the trig loop 11 that is fixed on the shell 10 with screw thread is supported on the hollow shaft 1 by B bearing 3, one end face of the A ring gear 7 that has A ratchet 8 as shown in Figure 6 withstands on the end face of internal clickwork circle 9, have four projections 12 in the hole of A ring gear 7 and constitute spline, A ring gear 7 and four A planetary pinion 13 engagements, four A planetary pinions 13 mesh with A central gear 14 again, A central gear 14 is keyed on the hollow shaft 1, A planetary pinion 13 is supported in the aperture as the planetary carrier 17 of Fig. 6-shown in Figure 8 by little axle 15 and A spring 16 respectively, little axle 15 stretches out outside the A planetary pinion 13 always under the effect of A spring 16, one side of A planetary carrier 17 has B ratchet 18, B ratchet 18 and the ratchet interlock of being with on the internal clickwork circle overcoat 19; Mesh with B central gear 21 as Fig. 1, B planetary pinion 20 shown in Figure 14, B central gear 21 is keyed on the hollow shaft 1, flying wheel 22 is fixed on by disk 23 on the B ring gear of being with in the internal clickwork circle overcoat 19 24, and B ring gear 24 is threaded with band internal clickwork circle overcoat 19.
As shown in Figure 1: the two ends of described hollow shaft 1 have outside thread, fix with nut, have two elongated slots 25 on the hollow shaft 1, withstand pull bar 27 by B spring 26 in the hollow shaft 1, the two ends of pull bar 27 have two apertures, one end sliding fit A axle sleeve 28 of hollow shaft 1, with by A bearing pin 29 cross shift fork 6 being fixed on the pull bar 27 in aperture of A bearing pin 29 insertions, in addition, the other end sliding fit B axle sleeve 30 of hollow shaft 1 inserts in another aperture with B bearing pin 31, by B bearing pin 31 slotted disk 32 is fixed on the pull bar 27, when pull bar 27 actions, cross shift fork 6 and slotted disk 32 interlocks.
As Fig. 2, shown in Figure 3: an end of described four paws sleeve 4 has four pawls, and the side of pawl has three inclined-planes point grooves 33, is bumped into A bearing 2 in another stomidium of four paws sleeve 4.
As Fig. 9, shown in Figure 10: described flying wheel 22 by disk 23, little axle 34, get rid of hammer 35 and lever 36 is formed, have four attachment holes on the disk 23, be connected with B ring gear 24 with bolt, get rid of hammer into shape 35 and lever 36 be integral, be supported on little 34.
When the electric vehicle automatic transmission is in quick grade of state: as shown in Figure 1: utilize centrifugal force and lever principle, speed changer automatic speed changing, in the time of quick grade, the hammer 35 that gets rid of on the flying wheel 22 opens up into maximum, at this moment, lever 36 promotes slotted disk 32 and drives pull bar 27 compression B springs 26, because of cross shift fork 6 and slotted disk 32 interlocks, then cross shift fork 6 moves to little axle 15 places and stirs A planetary pinion 13 and rotate, 13 direct and A central gear 14 engagements of A planetary pinion, at this moment, A planetary pinion 13 is initiatively, and it drives 7 motions of A ring gear again, A ring gear 7 is driven, A ratchet 8 on the A ring gear 7 is stirred internal clickwork circle 9 and is driven shell 10 and rotates, and the speed of this moment is 1: 1.6, the wheel quick rotation; Drive internal clickwork circle overcoat 19 and 24 rotations of B ring gear when shell 10 rotates, B ring gear 24 drives B planetary pinions 20 and rotates around B central gear 21, and at this moment, the disk 23 that is fixed together with B ring gear 24 drives flying wheel 22 rotations.
Its advantage is: simple in structure, flexible movements, be convenient to process, easy to use, easy grasp, electric motor car in the process of moving can automatic gear-shifting speed governing between three gears according to the hobby of oneself, applied range can be widely used in lithium battery motor-car, cart, tricycle and electrician's automobile etc.
Embodiment 2 is that example is illustrated with the electric motor car neutral gear
The mounting point of each component is all identical with embodiment 1 with Placement in the electric vehicle automatic transmission;
By quick shelves during to the neutral speed change, be that the electric vehicle automatic transmission is in neutral state: before each speed change, at first, should remove power (sprocket wheel of its power resources is fixed in the groove of four paws sleeve 4) earlier, the inclined-plane point groove 33 that allows cross shift fork 6 break away from the four paws sleeves 4 can speed change, when by fast normal when fast to neutral, the speed of a motor vehicle slows down gradually, as Fig. 9, Figure 10, shown in Figure 11: the hammer 35 that gets rid of on the flying wheel 22 draws in gradually, lever 36 left-hand to Figure 11 under the drive of getting rid of hammer 35 is swung, and loosened thrust to slotted disk 32, at this moment, the pull bar 27 in the hollow shaft 1 is under the effect of B spring 26, be moved to the left, because of cross shift fork 6 and slotted disk 32 interlocks, then cross shift fork 6 leaves little axle 15, and cross shift fork 6 is in the middle of projection 12 and the little axle 15, at this moment, speed changer is inoperative, and external power directly drives wheel, and its speed is 1: 1; Described B planetary pinion 20, B central gear 21, B ring gear 24 and disk 23 still play the effect that flying wheel 22 rotates that drives.
Its advantage is identical with embodiment 1.
Embodiment 3 is that example is illustrated with the slow shelves of electric motor car
The mounting point of each component is all identical with embodiment 1 with Placement in the electric vehicle automatic transmission;
By neutral gear during to the bottom gear speed change electric vehicle automatic transmission be in the bottom gear state: shift after laying down power, as Fig. 9, Figure 10, shown in Figure 12: flying wheel 22 draws in fully, lever 36 on the flying wheel 22 is thrown off slotted disk 32, under B spring 26 effects in hollow shaft 1 of slotted disk 32 and B bearing pin pull bar 27 is moved to the left, driving B bearing pin 31 moves, because of B bearing pin 31 and the A bearing pin of adorning on the pull bar 29 links, A bearing pin 29 also moves, drive 6 groups of splines of living on the A ring gear 7 of cross shift fork, (at this moment, A ratchet 8 is thrown off the internal clickwork circle on the internal clickwork circle shell 9), and drive A ring gear 7 engagement A planetary pinions 13, A planetary pinion 13 engagement A central gears 14, the A ring gear is initiatively, A planetary pinion 13 is driven, and it passes than being 0.7: 1, then the wheel low speed driving; Drive internal clickwork circle overcoat 19 and 24 rotations of B ring gear when shell 10 rotates, B ring gear 24 drives B planetary pinions 20 and rotates around B central gear 21, and at this moment, the disk 23 that is fixed together with B ring gear 24 drives flying wheel 22 rotations.
Its advantage is identical with embodiment 1.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
