Description
Technical field
The utility model is related to pure electric automobile speed changer, and in particular to a kind of shift transmission of pure electric automobile two.
Background technology
Pure electric automobile is a kind of clean energy vehicle, and with the promotion energetically of energy-saving and emission-reduction, pure electric automobile becomes
One developing direction.Although traditional pure electric gear shift(ing) disclosure satisfy that the functions such as speed governing traveling.But, due to traditional pure electricity
The decelerator of dynamic speed changer is fixed speed ratio so that the transmission efficiency of vehicle is low.And increase gear and can solve the problem that to two gears
The problem of above-mentioned vehicle transmission efficiency is low.
At present, the common shift transmission of a kind of pure electric automobile two, including motor and planet row, is changed to realize
Gear, using a non-centrifugal clutch and a brake, the problems of be；Respectively to non-centrifugal clutch and system
Dynamic device is controlled, and needs Liang Tao executing agencies and control system, structure is more complicated, cost is higher and shift process in it is same
When two sets of control systems are controlled, control difficulty it is larger.
Utility model content
The technical problems to be solved in the utility model be to provide that a kind of relatively simple for structure, control difficulty is smaller and cost compared with
The low shift transmission of pure electric automobile two.
In order to solve the above technical problems, the technical solution of the utility model is；
A kind of shift transmission of pure electric automobile two, including the motor comprising motor shaft, the decelerator comprising main shaft, bag
Planet row containing sun gear, planetary gear, planet carrier and gear ring, and outer ring, brake and clutch, the sun of the planet row
Wheel is located within planet carrier, planetary gear is rotatably installed on planet carrier, gear ring is installed on outside planet carrier, the driving electricity
The right-hand member of the motor shaft of machine and the planet carrier of planet row are connected firmly, the right-hand member of the sun gear of the planet row and the main shaft of decelerator
Left end is connected firmly, and the right-hand member of its gear ring and outer ring is connected firmly, it is characterized in that：The clutch is disconnection centrifugal clutch at a high speed, its
It is coupled simultaneously with the left end of outer ring and the planet carrier of planet row, the middle part of the outer ring is coupled with brake.Using said structure
Afterwards, the utility model can disconnect centrifugal clutch as gearshift using brake and at a high speed, and only brake needs to hold
Row mechanism and control system act to realize to disconnect or combine, and disconnect centrifugal clutch at a high speed and do not need executing agency and control
System processed can just be automatically performed disconnection according to speed or combine and realize gearshift function, that is, the utility model only needs to one
Set executing agency and control system can be realized as the gearshift of two gears, so relatively simple for structure, cost is relatively low.Meanwhile, during gearshift
Only need to be controlled brake.Then, control difficulty is smaller.In addition, in shift process, the braking procedure of brake is
Progressively carry out, correspondingly, the speed of automobile is with being changed stepwise, and whole braking procedure does not have power interruption, in the absence of gearshift
Impact, smooth gear shifting is also preferable.
As further improvement of the utility model, the brake is many friction disk type brakes.This causes this practicality
Smooth-going is compared in the new impact that can preferably buffer vehicle, gearshift.
More enter an improvement as of the present utility model, the clutch is that many friction plates disconnect at a high speed centrifugal clutch.
This enables the utility model preferably to buffer the impact of vehicle, gearshift and compares smooth-going.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Preferred embodiment of the present utility model is elaborated below in conjunction with the accompanying drawings.
It is shown in Figure 1, the shift transmission of the utility model pure electric automobile two, including include the motor of motor shaft 2
1st, the decelerator 11 comprising main shaft 7, include the planet row of sun gear 3, planetary gear 4, planet carrier 5 and gear ring 6, and outer ring 8, system
Dynamic device 9 and clutch 10, the sun gear 3 of the planet row is located within planet carrier 5, planetary gear 4 is rotatably installed on planet
On frame 5, gear ring 6 be installed on outside planet carrier 5, the right-hand member of the motor shaft 2 of the motor 1 and the planet carrier 5 of planet row are solid
Connection, the left end of the right-hand member of the sun gear 3 of the planet row and the main shaft 7 of decelerator 11 is connected firmly, its gear ring 6 and the right-hand member of outer ring 8
Connect firmly, the clutch 10 is disconnects at a high speed centrifugal clutch, its left end and the planet carrier 5 of planet row with outer ring 8 simultaneously
It is coupled, the middle part of the outer ring 8 is coupled with brake 9.
The brake 9 is many friction disk type brakes.
The clutch 10 is that many friction plates disconnect at a high speed centrifugal clutch.
Utility model works principle is as follows：
One gear change two is kept off；The low speed of motor 1 is rotated forward, and brake 9 unclamps, and clutch 10 is in bonding state.Driving
Power is passed to planet carrier 5 by motor 1 by motor shaft 2, whole in the case where gear ring 6 and planet carrier 5 are combined by clutch 10
Individual planet row is rotated together with sun gear 2, and imparts power to main shaft 7 and decelerator 11 by sun gear 3, now speed change
Device is in a gear, and when speed of the speed higher than setting, clutch 10 is progressively turned off automatically, and brake 9 is progressively combined, with
Speed further to be lifted, after clutch 10 is fully disconnected automatically, brake 9 is progressively completely combined, complete powershift, this
When speed changer be in two gear.
Two gear changes one are kept off；Motor 1 is rotated forward at a high speed, and brake 9 is braked, and clutch 10 is off.Driving
Power is passed to planet carrier 5 by motor 1 by motor shaft 2, and in the case where gear ring 6 is braked by brake 9, planet row passes through too
Sun wheel 3 imparts power to output shaft 7 and decelerator 11, and now speed changer is in two gears, when speed of the speed less than setting,
Brake 9 is progressively unclamped by on-position, and as speed is further reduced, clutch 10 is progressively combined automatically；Work as braking
After device 9 is totally released, clutch 10 is progressively completely combined, and completes powershift, and now speed changer is in a gear.
Reverse gear；The low speed and reverse of motor 1, brake 9 unclamps, and clutch 10 is in bonding state.Vehicle, which reverses gear, to be less than
Setting speed, clutch 10 is in bonding state all the time, and power is passed to planet carrier 5 by motor 1 by motor shaft 2,
In the case that the planet carrier 5 of gear ring 6 and planet row is combined by clutch 10, planet row is imparted power to defeated by sun gear 3
Shaft 7 and decelerator 11, transmission reverse gear operation.
Preferred embodiment of the present utility model is elaborated above in conjunction with accompanying drawing.But, the utility model is simultaneously
