Description
Technical field
The present invention relates to pure electric automobile, and in particular to a kind of pure electric vehicle power system.
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.At present, common pure electric vehicle power system, including the motor comprising motor shaft, include clutch
Speed changer, the output shaft of device and brake, and its sun gear is located within planet carrier, planetary gear is rotatably installed on planet
On frame, gear ring be located at planet row outside planet carrier, the right-hand member of the motor shaft of the motor and the sun gear of planet row are solid
Connection, right-hand member and the output shaft of the planet carrier of the planet row are connected firmly.This pure electric vehicle power system, in order to realize gearshift,
Its speed changer employs clutch and brake, the problems of be；In shift process, to prevent power interruption, it is necessary to same
When control clutch and brake, control difficulty is larger；To prevent from producing impact in shift process, and reduce in shift process
Impact is produced, the required precision to controlling organization is higher, and structure is more complicated, cost is higher.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of relatively simple for structure, cost is relatively low and control difficulty is less
Pure electric vehicle power system.
In order to solve the above technical problems, the pure electric vehicle power system of the present invention, including the electricity of the driving comprising motor shaft
Machine, the speed changer comprising clutch and brake, output shaft, and its sun gear is located within planet carrier, planetary gear is rotatable
Ground is installed on planet carrier, planet row of the gear ring outside planet carrier, the right-hand member and planet of the motor shaft of the motor
The sun gear of row is connected firmly, and right-hand member and the output shaft of the planet carrier of the planet row are connected firmly, it is characterised in that：Also include outer ring, list
To clutch, the clutch of the one-way clutch and speed changer or so side by side positioned at motor and planet row sun gear it
Between and one-way clutch outer shroud fix, the left end of inner ring and outer ring is connected firmly, the interior drum and the motor shaft of motor of clutch
Connection, external drum couple with the middle part of outer ring, and the right-hand member of the outer ring joins with the brake of speed changer and the gear ring of planet row respectively
Connect.After said structure, the present invention individually can be controlled in shift process to the clutch or brake of speed changer
And power interruption is occurred without, it controls difficulty low；, then can be with due to the clutch and brake of speed changer need not be controlled simultaneously
Avoid producing impact in shift process, the requirement to the controlling organization of gearshift is relatively low, and the structure of controlling organization also compares
It is relatively low compared with simple, cost.Meanwhile, in shift process, the combination to the braking procedure and clutch of the brake of speed changer
Progressively carry out, correspondingly, the speed of automobile is stepping, and whole process does not have power interruption, rushed in the absence of gearshift
Hit, smooth gear shifting is also preferable.
Further, the brake is many friction disk type brakes.This allows the invention to preferably buffer vehicle
Impact, gearshift more smooth out.
Further, the clutch is many friction plate clutch.This causes the enough preferably buffering vehicles of the present invention
Impact, gearshift are more smoothed out.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The preferred embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.
Referring to Fig. 1, pure electric vehicle power system of the invention, including the motor 1 comprising motor shaft 2, comprising from
Speed changer, the output shaft 10 of clutch 7 and brake 8, and its sun gear 3 be located at planet carrier 5 within, planetary gear 4 rotationally
Be installed on planet carrier 5, gear ring 6 be located at planet carrier 5 outside planet row, the right-hand member and row of the motor shaft 2 of the motor 1
The sun gear 3 of star row is connected firmly, and right-hand member and the output shaft 10 of the planet carrier 5 of the planet row are connected firmly.As seen from Figure 1, the present invention is gone back
Including outer ring 9, one-way clutch 11, the clutch 7 or so of the one-way clutch 11 and speed changer is located at motor 1 side by side
Between the sun gear 3 of planet row and one-way clutch 11 outer shroud fix, the left end of inner ring and outer ring 9 is connected firmly, clutch 7
Interior drum couples with the motor shaft 2 of motor 1, external drum couples with the middle part of outer ring 9, the right-hand member of the outer ring 9 respectively with speed change
The brake 8 of device and the gear ring 6 of planet row couple.
The brake 8 is many friction disk type brakes.
The clutch 7 is many friction plate clutch.
Operation principle of the present invention is as follows；
One gear change two is kept off；Motor 1 is rotated forward, and clutch 7 disconnects, and brake 8 is braked.Power is passed through electricity by motor 1
Arbor 2 passes to sun gear 3, in the case where the gear ring 6 of planet row is braked by brake 8, and planet row will be dynamic by planet carrier 5
Power passes to output shaft 10, now speed changer be in one gear, speed changer will change to two keep off when, brake 8 by on-position progressively
Unclamp, one-way clutch 11 is combined under dynamic action, and the gear ring 6 of planet row and outer ring 9 remain in that and do not turned, until brake
After 8 are totally released, clutch 7 is progressively combined, after clutch 7 is completely combined, and completes powershift, and now speed changer is in two
Gear.
Two gear changes one are kept off；Motor 1 is rotated forward, and clutch 7 is combined, and brake 8 unclamps, and one-way clutch 11 disconnects.
Motor 1 passes to power by motor shaft 2 sun gear 3 of planet row, in the case where clutch 7 is combined, planet row
Sun gear 3 and gear ring 6 it is affixed, turn together with sun gear 3, planetary gear 4, planet carrier 5 and the gear ring 6 of planet row are overall with outer ring 9
Dynamic, power passes to output shaft 10 by planet carrier 5, and now speed changer is in two gears, when speed changer keeps off change one, clutch
7 are progressively unclamped by bonding state, after clutch 7 is fully disconnected, the gear ring 6 arranged in dynamic action lower planet and outer ring 9
Rotate by rotating forward vanishing and then there is the trend inverted so that one-way clutch 11 is combined, until brake 8 is progressively braked,
Brake 8 is braked completely, completes powershift, and now speed changer is in a gear.
Reverse gear：Motor 1 is inverted, and clutch 7 disconnects, and brake 8 is braked.Power is passed through motor shaft 2 by motor 1
The sun gear 3 of planet row is passed to, in the case where the gear ring 6 of planet row is braked by brake 8, planet row passes through planet carrier 5
Impart power to output shaft 10, 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
Embodiment, in the knowledge 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.
