Enter the first seat board 11 to be open in a hole at interior bottom, the first guide post 30 can be sliding along the direction for being parallel to shift lever axis 10 in hole
Dynamic, fork handle is in sleeve-shaped, and the both ends of fork handle are glued with respectively to be placed on shift lever axis 10 and can be along the institute in axial sliding of shift lever axis 10
Gripping sleeve 27 is stated, two gripping sleeves 27 are equipped with a ring annular groove on the external cylindrical surface of fork handle one end, slide the one of connecting plate 13
End is stuck in annular groove, and the other end is buckled on the bottom plate of the first seat board 11 and can slide axially along bottom plate along shift lever axis 10,
Two cylindrical springs 12 cover on shift lever axis 10 by 11 ground of the first seat board respectively, and 12 one end of cylindrical spring is withstood on side plate, the other end
It covers outside gripping sleeve 27 and on the shaft shoulder end face for withstanding on gripping sleeve 27, so that cylindrical spring 12 is compressed in the first seat board 11
Between side plate and corresponding gripping sleeve 27, to allow the first shift fork by the elastic compression of two cylindrical springs 12.Second shift fork group
Part includes in " [the second seat board 17 of " type is respectively positioned on connecting in the second seat board 17 opening for stirring the second balladeur train 25
The fork handle 16 of second shift fork of transmission, cylindrical holddown spring 18, bottom is equipped with strip-shaped hole in the opening of the second seat board 17, the
16 bottom of fork handle of two shift forks is equipped with the second guide post 31, and the second guide post 31 protrudes into strip-shaped hole and can be in strip-shaped hole along putting down
Row is slided in the direction of shift lever axis 10, and the second shift fork fork handle is axially arranged with the recessed of annular shape along it by one end of the first pull-fork assembly
Chamber, holddown spring 18 in squeezed state protrude into the cavity by one end, in the opening side plate of the other end and the second seat board 17
Wall close proximity.It is respectively and fixedly provided with traveller 26 on the opening outer bottom of the mutually close one end of the first, second seat board 17, traveller 26 is located at
Corresponding shift fork is driven to stir corresponding balladeur train to realize gear shift in gear shift slot 901 and in the shift post 9 rotation.
As shown in Fig. 2,7, change gear component includes several transmission shaft components, the transmission shaft of two of them transmission shaft component
On be respectively equipped with first balladeur train 24 and the first balladeur train 24, one end of two balladeur trains is coaxially connected with movable sleeve
23, two balladeur trains and movable sleeve 23 are rotationally placed on the transmission shaft at respective place, and the external cylindrical surface of movable sleeve 23
On along it be axially arranged with external splines structure, transmission shaft is fixedly cased with fixing sleeve 22, fixing sleeve 22 at the position of slide cartridge
It is equipped with external splines, the inner spline housing 21 with its spline fitted, the shift fork fork of two pull-fork assemblies are also cased with outside fixing sleeve 22
Head be stuck in the outside of inner spline housing 21 and can drive inner spline housing 21 slided to along axial direction and meanwhile with movable sleeve 23 and fixing sleeve
22 positions matched.For the corresponding spline structure on inner spline housing 21, fixing sleeve 22 and movable sleeve 23, spline tooth is preferably selected
Type is identical, also can choose different size of flute profile, if meet inner spline housing 21 can simultaneously with movable sleeve 23 and fixing sleeve
Spline structure outside 22 is connected.I.e. in the rotation process of shift post 9, shift fork pushes one of inner spline housing
21 move axially to the position that adjacent fixing sleeve 22 is mutually bridged with movable sleeve 23, so that corresponding balladeur train and 22 institute of fixing sleeve
Transmission shaft between secure fit become from rotatable cooperation, it is real so that balladeur train be made to work initially as transmission gear
It is existing shifted.And the presence of cylindrical spring 12 makes corresponding shift fork movement reliable much sooner, changes when traveller 26 moves to
When the deformation section of shelves groove 901, traveller 26 will no longer merely move in a circle with respect to 9 center of circle of shift post, but be aided with a court
So that traveller 26 is axial towards selector shaft 8, or dialled along the axial changed offset movement of shift post 9 in 901 path of gear shift slot
The axial movement towards yoke bar is pitched, and more stable when 12 elastic reaction lower shift fork of cylindrical spring is mobile, is not in shake,
So that inner spline housing 21 bridges fixing sleeve 22 and movable sleeve 23.
Further, there are two curved towards 9 axis both ends of shift post respectively for the tool of gear shift slot 901 in one of shift post 9
Arched is turned groove portion, the gear shift slot 901 of another shift post 9 have one towards turning groove portion described in arching upward outside shift post 9,
So that the slot diameter variation of gear shift slot 901 is consistent with the gear shift moving direction height of driving lever component, gear shift effect is more preferable for the design,
Gear shift is more accurate in time.
Further, there are two cylinders of different sizes for the part fixation of 1 output shaft of the motor stretching, 1 shell end face of motor
Gear 3, and wherein lesser roller gear 3 is arranged by 1 shell end face of motor, 1 shell end face of motor is additionally provided with parallel with output shaft
Mandrel 28, set on mandrel 28 there are two can respectively with two 3 meshed gears of roller gear on output shaft.The design is so that change
The output of motor 1 of shelves is more steady, and 4 worm screw of worm gear, 2 mechanism driving is stablized, the cooperation between gear shift slot 901 and traveller 26
Variation relation plays facilitation.
Further, the plug is semicircular circular arc batten, convenient for connecting with the ring groove on inner spline housing 21
The transmission connection that inner spline housing 21 realizes balladeur train and transmission shaft where it is stirred rapidly in cooperation.
Further, the sliding connecting plate 13 is stuck in the circular arc batten structure of the part semicircular in shape in annular groove, button
Part on the bottom plate of the first seat board 11 is in Π type, and the on both sides of the middle of the bottom plate in the first seat board 11 extends outwardly into limit
Lug boss 29, lug boss 29 by two sliding connecting plates 13 separately be isolated so that sliding win in succession slide it is more stable, while be shift fork axis
Preferable guiding role is played to sliding, promotes the stabilization accuracy of gear shift.
Further, the end of the transmission shaft where two balladeur trains is equipped with the revolving speed for detecting rotating speed of transmission shaft
Sensor, the speed probe acquisition signal make controller that the motor 1 be driven to rotate after passing to controller.The structure
Designing manually can also be automatic when allowing gear shift, auto-manual is realized, in addition to being mounted directly control switch and 1 phase of motor
Even, the automatic speed-changing system that can also be arranged in pairs or groups using such speed probe and controller.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
