Description
Technical field
The present invention relates to pure electric automobile speed changer, and in particular to a kind of shift transmission of pure electric automobile planet row type two.
Background technology
Pure electric automobile is a kind of clean energy vehicle, and as the promotion energetically of energy-saving and emission-reduction is pure, electric automobile becomes
One developing direction.Although traditional pure electric automobile speed changer disclosure satisfy that the functions such as speed governing traveling.But, due to traditional
The decelerator of pure electric automobile speed changer is fixed speed ratio so that the transmission efficiency of vehicle is low.And increase gear to two gears
Can solve the problem that the low problem of above-mentioned vehicle transmission efficiency.
At present, the common shift transmission of pure electric automobile planet row type two, including motor and planet row, in order to realize
Gearshift, using a non-centrifugal clutch and a brake, the problems of be；Respectively to non-centrifugal clutch and
Brake is controlled, and needs Liang Tao executing agencies and control system, structure is more complicated, relatively costly and shift process in
Two sets of control systems are controlled simultaneously, control difficulty is larger.
The content of the invention
The technical problem to be solved in the present invention is to provide that a kind of relatively simple for structure, cost is relatively low and control difficulty is less
The shift transmission of pure electric automobile planet row type two.
In order to solve the above technical problems, the technical scheme is that；
A kind of shift transmission of pure electric automobile planet row type two, including motor, motor shaft, output shaft and outer ring, clutch
And brake, and its sun gear is located within planet carrier, planetary gear is rotatably installed on planet carrier, gear ring is located at planet
Planet row outside frame, the right-hand member of the motor shaft of the motor is connected firmly with the sun gear of planet row, the row of the planet row
The right-hand member of carrier is connected firmly with output shaft, and the gear ring is connected firmly with the left end of outer ring, it is characterised in that：The clutch is tied for high speed
Centrifugal clutch is closed, it is coupled with the right-hand member of outer ring and the planet carrier of planet row respectively, the middle part of the brake and outer ring
It is coupled.After said structure, the present invention can combine centrifugal clutch and brake as gearshift using high speed, and
Only brake needs extra increase executing agency and control system to realize disconnecting or combining action, and combines at a high speed centrifugal
Clutch can be automatically performed according to speed and disconnect or combine and realize gearshift function, it is not necessary to extra to increase executing agency and control
System processed, the i.e. present invention only need to a control system being controlled to brake.Thus, the pure electronic vapour with prior art
The shift transmission of car planet row type two is compared, and relatively simple for structure, cost is relatively low, and control difficulty is smaller.Meanwhile, in shift process
In, the braking procedure of brake is progressively carried out, and correspondingly, with being changed stepwise, whole braking procedure does not have the speed of automobile
Dynamic interruption, in the absence of shift shock, smooth gear shifting is also preferable.
As it is of the invention enter an improvement, the brake be many friction disk type brakes.This is allowed the invention to more
The impact of vehicle, gearshift are buffered well compares smooth-going.
As it is of the invention enter an improvement, the centrifugal clutch be many friction plates at a high speed combine centrifugal clutch.
This causes that the impact of the enough preferably buffering vehicles of the present invention, gearshift are more smoothed out.
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.
Referring to Fig. 1, the shift transmission of pure electric automobile planet row type two of the present invention, including motor 1, motor shaft 2, output
Axle 7 and outer ring 8, clutch 10 and brake 9, and its sun gear 3 is located within planet carrier 5, planetary gear 3 is rotatably mounted
In on planet carrier 5, gear ring 6 be located at planet carrier 5 outside planet row, the right-hand member and planet row of the motor shaft 2 of the motor 1
Sun gear 3 connect firmly, right-hand member and the output shaft 7 of the planet carrier 5 of the planet row are connected firmly, and the left end of the gear ring 6 and outer ring 8 is consolidated
Connection.As shown in Figure 1, the clutch 10 is to combine centrifugal clutch at a high speed, its respectively with the right-hand member of outer ring 8 and planet row
Planet carrier 5 is coupled, and the brake 9 is coupled with the middle part of outer ring 8.
The brake 9 is many friction disk type brakes.
The centrifugal clutch 10 is that many friction plates combine centrifugal clutch at a high speed.
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 is braked, at a high speed with reference to the clutch 10 of centrifugal clutch
（Hereinafter referred to as clutch 10）It is off.Power is passed to sun gear 2 by motor 1 by motor shaft 2, in gear ring
In the case that 6 are braked by brake 9, planet row imparts power to output shaft 7 by planet carrier 5, and now speed changer is in one
Gear, when speed of the speed higher than setting, brake 9 is progressively unclamped by on-position, as speed is further lifted, clutch
10 are progressively combined automatically；After brake 9 is totally released, clutch 10 is completely combined, and completes powershift, now speed change
Device is in two gears.
Two gears change to a gear；Motor 1 is rotated forward at a high speed, and brake 9 unclamps, and clutch 10 is in bonding state.Drive
Power is passed to sun gear 2 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 output shaft 7 by planet carrier 5, and now speed changer is in two
Gear；When speed of the speed less than setting, clutch 10 is progressively turned off automatically, and brake 9 is progressively combined, as speed is entered
One step declines, and after clutch 10 is fully disconnected automatically, brake 9 is progressively completely combined, and completes powershift, now speed changer
In a gear.
Reverse gear：The low speed and reverse of motor 1, brake 9 is braked, and clutch 10 is off.Vehicle reverses gear and is less than
Setting speed, clutch 10 is off all the time, and power is passed to sun gear 2 by motor 1 by motor shaft 2,
In the case that gear ring 6 is braked by brake 9, planet row imparts power to output shaft 7, transmission reverse gear fortune by planet carrier 5
OK.
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.
