Engagement, it is meant that gear of the internal tooth arrangement of sliding sleeve 13 not with the second synchronous gear tapered sleeve 28 engages, and this state is that this practicality is new
The state one of type；
In the case of state one, motor driven input gear 26 rotates, then first be fixed on input gear 26 is same
Step tooth tapered sleeve 27 is driven rotation, and drives intermeshing sliding sleeve 13, synchronizing tooth ring 15 to rotate, and then drives fixed toothholder 16
Rotate, final fixed toothholder 16 drives output shaft 18 to rotate output power, reaches speed change purpose；The rotational band of input gear 26 simultaneously
Nutating gear 22, jackshaft 21 rotate, that is, drive output gear 20 to rotate, thus when be connected to the second synchronous of output gear 20
Tooth tapered sleeve 28 separates with sliding sleeve 13, therefore output gear 20 dallies.
Magnetic field is produced when being powered with the magnet coil 3 of the homonymy of output gear 20, attracts matched permanent magnet rings 5,
The magnet coil 3 of opposite side powers off, and the permanent magnet rings 5 being magnetically attracted drive electromagnetism of the fork axle 11 to the side of output gear 20
Coil 3 moves, then the adjusting rod of shifting fork 9 and connection shifting fork 9 moves in the same direction, when corresponding concave inward structure is moved to
During the lower section in corresponding hole, the second compression spring 7 in corresponding aperture makes steel ball 8 with coordinating the concave inward structure of steel ball 8 to be combined, fork
Axle 11 is limited and no longer moved, and now adjusting rod drives movement of the sliding sleeve 13 to output gear 20 to stop simultaneously, and sliding sleeve 13
Internal tooth arrangement and synchronizing tooth ring 15, the gear of the second synchronous gear tapered sleeve 28 is intermeshed, it is meant that the internal tooth arrangement of sliding sleeve 13
The gear with the first synchronous gear tapered sleeve 27 does not engage, and this state is state two of the present utility model；
In the case of state two, motor driven input gear 26 rotates, the rotational band nutating gear 22 of input gear 26,
Jackshaft 21 rotates, that is, drive output gear 20 rotate, output gear 20 drive the second synchronous gear tapered sleeve 28 rotate, that is, drive with
The sliding sleeve 13 of the gear engagement of second synchronous gear tapered sleeve 28 rotates, and sliding sleeve 13, which rotates, drives intermeshing 15 turns of synchronizing tooth ring
It is dynamic, and then drive fixed toothholder 16 to rotate, drive output shaft 18 to rotate output power, reach deceleration purpose, and it is now first same
Step tooth tapered sleeve 27 separates with sliding sleeve 13, therefore does not influence the rotation of input gear 26.
By the switching of state one and state two, shift process is easily realized, it is simple to operate, pass through nibbling for a small number of gears
Close and reach speed change purpose, improve transmission effect.
The utility model mounting means is various, can be installed using axis connection mode and also be installed using hole connected mode, this
Embodiment takes hole connected mode installation.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
