Cavity, holddown spring 18 in squeezed state protrude into the cavity by one end, the opening side plate of the other end and the second seat board 17
Inner wall close proximity.Traveller 26, traveller 26 are respectively and fixedly provided on the opening outer bottom of the mutually close one end of the first, second seat board 17
It in shift slot 901 and drives corresponding shift fork to stir corresponding balladeur train in the shift post 9 rotation to change to realize
Gear.
Said gear shifting lever component, driving lever component, power shift gear component are mounted on an individual casing and (do not show in figure
In out), the output shaft in the transmission shaft component is directly with the input gear in rear axle gear-box (not shown) (in figure
Be not shown) engagement, rear axle gear-box herein can according to shift bar assembly, driving lever component, power shift gear component size and
The radical of concrete shape adaptability design, transmission shaft can also be according to specific transmission ratio flexible design, this reality of specific constructive form
It applies example to be not particularly limited and be described in detail, shift bar assembly, driving lever component in the present embodiment, power shift gear component are formed
Transmission shifting mechanism structure it is simple, compact, be very suitable to directly connect with rear axle gearbox drive, without as tradition pass
Dynamic speed change is the same, transmission shifting mechanism is arranged far to the void spaces of rear axle, to directly remove one big section of intermediate transmission
Chain, transmission efficiency are keeping efficient premise flowering structure more stable.
As shown in Fig. 2,7, power shift 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 column 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
Existing shift speed change.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 retaining groove 901, traveller 26 will no longer merely opposite shift 9 center of circle of column moves in a circle, but is aided with a court
901 path of slot shift gears along the axial changed offset movement of shift column 9, so that traveller 26 is axial towards shifting shaft 8, or dials
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.

Arched is turned groove portion, the shift slot 901 of another shift column 9 have one towards turning groove portion described in arching upward outside column 9 of shifting gears,
So that the slot diameter variation of shift slot 901 is consistent with the shift moving direction height of driving lever component, shift effect is more preferable for the design,
It shifts gears more accurate timely.
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 gear is more steady, and 4 worm screw of worm gear, 2 mechanism driving is stablized, for the cooperation between 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 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
Design allows manually can also be automatic when shifting gears, and 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
