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 consolidated
Connection, right-hand member and the output shaft of the planet carrier of the planet row connect 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.
Utility model content
The technical problems to be solved in the utility model be to provide that a kind of relatively simple for structure, cost is relatively low and control difficulty compared with
Small pure electric vehicle power system.
In order to solve the above technical problems, pure electric vehicle power system of the present utility model, 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 is located at planet row outside planet carrier, the right-hand member of the motor shaft of the motor with
The sun gear of planet row connects firmly, and right-hand member and the output shaft of the planet carrier of the planet row connect firmly, it is characterised in that：Also include outer
Circle, one-way clutch, the clutch of the one-way clutch and speed changer or so are located at motor and planet row too side by side
Between sun wheel and one-way clutch outer shroud fix, the left end of inner ring and outer ring connects firmly, the interior drum and motor of clutch
Motor shaft connection, external drum couple with the middle part of outer ring, the right-hand member of the outer ring respectively with the brake of speed changer and planet row
Gear ring couples.After said structure, the utility model can the individually clutch to speed changer or braking in shift process
Device is controlled and occurs without power interruption, and it controls difficulty low；Due to the clutch and system of speed changer need not be controlled simultaneously
Dynamic device, then it can avoid producing impact in shift process, the requirement to the controlling organization of gearshift is relatively low, controlling organization
Structure is also fairly simple, cost is relatively low.Meanwhile in shift process, braking procedure to the brake of speed changer and from
The combination of clutch is progressively carried out, and correspondingly, the speed of automobile is stepping, and whole process does not have power interruption, no
Shift shock be present, smooth gear shifting is also preferable.
Further, the brake is more friction disk type brakes.This enables the utility model preferably to buffer
Impact, the gearshift of vehicle more smooth out.
Further, the clutch is more friction plate clutch.It is whole that this make it that the utility model enough preferably buffers
Impact, the gearshift of car more smooth out.
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.
Referring to Fig. 1, pure electric vehicle power system of the present utility model, 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
It is installed on dynamicly on planet carrier 5, gear ring 6 is located at planet row outside planet carrier 5, the right-hand member of the motor shaft 2 of the motor 1
Connected firmly with the sun gear 3 of planet row, right-hand member and the output shaft 10 of the planet carrier 5 of the planet row connect firmly.As seen from Figure 1, this reality
Also include outer ring 9, one-way clutch 11 with new, the clutch 7 or so of the one-way clutch 11 and speed changer is located at side by side
Between motor 1 and 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 connects firmly,
The interior drum of clutch 7 couples with the motor shaft 2 of motor 1, external drum couples with the middle part of outer ring 9, the right-hand member point of the outer ring 9
Do not couple with the brake 8 of speed changer and the gear ring 6 of planet row.
The brake 8 is more friction disk type brakes.
The clutch 7 is more friction plate clutch.
Utility model works principle is as follows；
The gear of one gear change two；Motor 1 is rotated forward, and clutch 7 disconnects, and brake 8 is braked.Motor 1 leads to power
Cross motor shaft 2 and pass to sun gear 3, in the case where the gear ring 6 of planet row is braked by brake 8, planet row passes through planet carrier 5
Output shaft 10 is imparted power to, now speed changer is in a gear, and when speed changer will change to two gears, brake 8 is by on-position
Progressively unclamp, one-way clutch 11 combines under dynamic action, and the gear ring 6 of planet row and outer ring 9 remain in that and do not turned, until system
After dynamic device 8 is totally released, clutch 7 progressively combines, and after clutch 7 is completely combined, completes powershift, now speed changer is in
Two gears.
The gear of two gear change one；Motor 1 rotates forward, and clutch 7 combines, 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 combines, 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 will change to a gear, clutch
7 progressively unclamped by bonding state, after clutch 7 is fully disconnected, gear ring 6 and outer ring 9 in dynamic action lower planet row
Rotating by rotating forward vanishing and then there is the trend inverted so that one-way clutch 11 combines, 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.
Preferred embodiment of the present utility model is elaborated above in conjunction with accompanying drawing, but the utility model is not
It is limited to above-mentioned embodiment, in art those of ordinary skill's possessed knowledge, can also departing from
Various changes can be made on the premise of the utility model aims.
