Description
Technical field
The present invention relates to pure electric vehicle power system, and in particular to a kind of two keep off pure electric vehicle power system.
Background technology
At present, common two gears pure electric vehicle power systems, including the motor comprising motor shaft, comprising clutch
Speed changer, output shaft with brake, and its sun gear is located within planet carrier, planetary gear is rotatably installed on planet carrier
Upper, gear ring is located at the planet row outside planet carrier, and the right-hand member of the motor shaft of the motor is connected firmly with the sun gear of planet row,
The right-hand member of the planet carrier of the planet row is connected firmly with output shaft.Two gear pure electric vehicle power systems of this structure, it is existing
Problem be;In order to realize gearshift, speed changer uses a clutch and a brake, is anti-stopping power in shift process
Interrupt, need to simultaneously control clutch and brake, its control difficulty is larger, to prevent producing impact in shift process, to control
The required precision of mechanism is higher, structure is more complicated, high cost.
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
Two gear pure electric vehicle power systems.
In order to solve the above technical problems, two gears pure electric vehicle power system of the invention, including the drive comprising motor shaft
Dynamic motor, the speed changer comprising clutch and brake, output shaft, and its sun gear is located within planet carrier, planetary gear can
Be rotatably mounted on planet carrier, gear ring be located at planet carrier outside planet row, the right-hand member of the motor shaft of the motor with
The sun gear of planet 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
And one-way clutch, the clutch of the one-way clutch and speed changer or so is located at motor and planet row too side by side
Between sun wheel and one-way clutch outer shroud fix, the left end connection of inner ring and outer ring, the interior drum of the clutch of speed changer with drive
The motor shaft connection of dynamic motor, external drum couples with the left end of the planet carrier of planet row, the right-hand member of the outer ring and the tooth of planet row
Circle is connected firmly, middle part couples with brake.After said structure, the present invention in shift process can individually to speed changer from
Clutch or brake are respectively controlled and occur without power interruption, thus control difficulty is smaller;Clutch need not simultaneously be controlled
The impact produced in shift process can be just avoided with brake, the requirement to controlling organization is relatively low thus relatively simple for structure,
Cost is relatively low.Additionally, in shift process, the braking procedure and clutch of brake are combined and progressively carried out, and correspondingly, vapour
With being changed stepwise, whole process does not have power interruption to the speed of car, and in the absence of shift shock, smooth gear shifting is also preferable.
Further, the brake of the speed changer is many friction disk type brakes.This is allowed the invention to preferably
The impact of vehicle, gearshift is buffered more to smooth out.
Further, the clutch of the speed changer is many friction plate clutch.This causes that the present invention is enough preferably
The impact of vehicle, gearshift is buffered more to smooth 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, two gears pure electric vehicle power system of the invention, including the motor 1 comprising motor shaft 2, bag
Speed changer containing clutch 7 and brake 8, output shaft 10, and its sun gear 3 is located within planet carrier 5, planetary gear 4 can turn
Be installed on dynamicly on planet carrier 5, gear ring 6 be located at planet carrier 5 outside planet row, the right-hand member of the motor shaft 2 of the motor 1
Sun gear 3 with planet 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, this hair
Bright also to include outer ring 9 and one-way clutch 11, the one-way clutch 11 is located at and drives side by side with the clutch 7 or so of speed changer
It is dynamic between motor 1 and the sun gear 3 of planet row and one-way clutch 11 outer shroud fix, the left end connection of inner ring and outer ring 9, become
The interior drum of the clutch 7 of fast device is connected with the motor shaft 2 of motor 1, external drum couples with the left end of the planet carrier 5 of planet row,
The right-hand member of the outer ring 9 is connected firmly with the gear ring 6 of planet row, middle part couples with brake 8.
The brake 8 of the speed changer is many friction disk type brakes.
The clutch 7 of the speed changer is many friction plate clutch.
Operation principle of the present invention is as follows;
One gear changes to two gears;Motor 1 is rotated forward, and the clutch 7 of speed changer is disconnected, brake 8 is braked.Motor 1 will be dynamic
Power passes to the sun gear 3 of planet row by motor shaft 2, in the situation that the gear ring 6 of planet row is braked by the brake 8 of speed changer
Under, planet row imparts power to output shaft 10 by planet carrier 5, and now speed changer is in a gear;Speed changer will change to two gears
When, the brake 8 of speed changer is progressively unclamped by on-position, and one-way clutch 11 is combined under dynamic action so that planet row
Gear ring 6 remain in that and do not turn that after the brake 8 of speed changer is totally released, clutch 7 is progressively combined, clutch 7 is complete
After full combination, powershift is completed, now speed changer is in two gears.
Two gears change to a gear;Motor 1 is rotated forward, and the clutch 7 of speed changer is combined, brake 8 unclamps, one-way clutch
11 disconnect.Power is passed to motor 1 sun gear 3 of planet row by motor shaft 2, is combined in the clutch 7 of speed changer
In the case of, the sun gear 3 and planet carrier 5 of planet row are affixed so that the sun gear 3 of planet row, planetary gear 4, planet carrier 5, tooth
Circle 6 is overall to be rotated together, and power passes to output shaft 10 by the planet carrier 5 of planet row, and now speed changer is in two gears;Speed change
When device will change to a gear, the clutch 7 of speed changer is progressively unclamped by bonding state, after clutch 7 is fully disconnected, in power
Then the rotation of the gear ring 6 of effect lower planet row there is the trend of reversion by rotating forward vanishing, combines one-way clutch 11,
Until the brake 8 of speed changer is progressively braked, after brake 8 is braked completely, powershift is completed, now speed changer is in one
Gear.
Reverse gear:Motor 1 is inverted, and the clutch 7 of speed changer is disconnected, brake 8 is braked.Motor 1 leads to power
The sun gear 3 that motor shaft 2 passes to planet row is crossed, in the case where the gear ring 6 of planet row is braked by the brake 8 of speed changer,
Planet row imparts power to output shaft 10, transmission reverse gear operation by planet carrier 5.
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.
