Description

A kind of shift transmission of pure electric automobile two
Technical field
The present invention relates to pure electric automobile, 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 be can solve the problem that to two gears The low problem of above-mentioned vehicle transmission efficiency.
At present, a kind of common shift transmission of pure electric automobile two, including motor and planet row, in order to realize changing 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, relatively costly and shift process in it is same When two sets of control systems are controlled, control difficulty it is larger.
The content of the invention
It is smaller and lower-cost that the technical problem to be solved in the present invention is to provide a kind of relatively simple for structure, control difficulty The shift transmission of pure electric automobile two.
In order to solve the above technical problems, the technical scheme is that;
A kind of shift transmission of pure electric automobile two, including the motor comprising motor shaft, the decelerator comprising main shaft, comprising too The planet row of positive wheel, planetary gear, planet carrier and gear ring, and outer ring, brake and clutch, the sun gear position of the planet row Within planet carrier, outside planetary gear is rotatably installed on planet carrier, gear ring is installed on planet carrier, the motor The right-hand member of motor shaft is connected firmly with the planet carrier of planet row, the left end of the right-hand member of the sun gear of the planet row and the main shaft of decelerator Connect firmly, its gear ring is connected firmly with the right-hand member of outer ring, it is characterized in that:, to disconnect centrifugal clutch at a high speed, it is simultaneously for the clutch It is coupled 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.After said structure, this Invention can disconnect centrifugal clutch as gearshift using brake and at a high speed, and only brake needs executing agency and control System processed is realized disconnecting or combines action, and is disconnected centrifugal clutch at a high speed and do not needed executing agency and control system with regard to energy It is enough disconnection to be automatically performed according to speed or is combined and is realized gearshift function, that is, the present invention only needs to set of execution mechanism and control System processed can be realized as the gearshift of two gears, so relatively simple for structure, cost is relatively low.Meanwhile, only needed to brake during gearshift It is controlled.Then, control difficulty is smaller.Additionally, in shift process, the braking procedure of brake is progressively carried out, phase Ying Di, with being changed stepwise, whole braking procedure does not have power interruption to the speed of automobile, in the absence of shift shock, smooth gear shifting Property is also preferable.
As a further improvement on the present invention, the brake is many friction disk type brakes.This is allowed the invention to Preferably buffer the impact of vehicle, gearshift and compare smooth-going.
More enter an improvement as of the invention, the clutch is that many friction plates disconnect at a high speed centrifugal clutch.This makes Obtain the impact that can preferably buffer vehicle of the invention, gearshift and compare smooth-going.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
The preferred embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.
It is shown in Figure 1, the shift transmission of pure electric automobile of the present invention two, including the motor 1 comprising motor shaft 2, bag Decelerator 11 containing main shaft 7, the planet row comprising sun gear 3, planetary gear 4, planet carrier 5 and gear ring 6, and outer ring 8, brake 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 carrier 5 Upper, gear ring 6 is installed on outside planet carrier 5, and the right-hand member of the motor shaft 2 of the motor 1 is connected firmly with the planet carrier 5 of planet row, The right-hand member of the sun gear 3 of the planet row is connected firmly with the left end of the main shaft 7 of decelerator 11, and its gear ring 6 is consolidated with the right-hand member of outer ring 8 Connection, the clutch 10 disconnects centrifugal clutch for high speed, its left end and the planet carrier 5 of planet row simultaneously with outer ring 8 Knot, 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.
Operation principle of the present invention is as follows:
One gear changes to two gears;The low speed of motor 1 is rotated forward, and brake 9 unclamps, and clutch 10 is in bonding state.Motor 1 Power is passed into planet carrier 5 by motor shaft 2, in the case where gear ring 6 and planet carrier 5 are combined by clutch 10, whole row Star row rotates together with sun gear 2, and imparts power to main shaft 7 and decelerator 11 by sun gear 3, now at speed changer In a gear, when speed of the speed higher than setting, clutch 10 is progressively turned off automatically, and brake 9 is progressively combined, with speed Degree further lifting, after clutch 10 is fully disconnected automatically, brake 9 is progressively completely combined, and completes powershift, this time-varying Fast device is in two gears.
Two gears change to a gear;Motor 1 is rotated forward at a high speed, and brake 9 is braked, and clutch 10 is off.Drive 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 is by 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 reverses gear and is 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.
The preferred embodiment of the present invention is elaborated above in conjunction with accompanying drawing, but the present invention be not limited to it is above-mentioned Implementation method, in the ken that art those of ordinary skill possesses, can also not depart from ancestor of the present invention Various changes can be made on the premise of purport.
