The transmission is formed by a motor, a spindle, a first planet row, a second planet row, a third planet row, a first brake, a second brake and a third brake which are all installed in a casing and the casing. The first planet row, the second planet row and the third planet row are all formed by respective sun gears, planet gears, planet carriers and gear rings, the sun gears of the first planet row, the second planet row and the third planet row are all connected with a rotor of the motor through the spindle, a gear ring of the first planet row is connected with a planet carrier of the second planet row, a gear ring of the second planet ring is connected with the planet carrier of the third planet row, the gear rings of the first planet row, the second planet row and the third planet row are respectively and correspondingly installed with the first brake, the second brake and the third brake. The transmission special for the novel pure electric bus is scientific and reasonable in structural design, has the advantages of being small in size, light in weigh, oil -saving and electricity-saving, is widely applied to working conditions, and has market popularization value.
Description
Technical field
The invention belongs to the automotive transmission field, particularly a kind of Novel pure electric bus dedicated transmission.
Background technique
At present, the speed changer of pure electric bus comprises motor-direct-drive type and motor+two kinds of forms of two～fourth gear AMT.Wherein, it is comparatively extensive that motor-direct-drive type is used, have advantages of simple in structure, but there are the following problems for it: need capacity motor large, and need low-speed big, so energy consumption is high, electricity decreases high; And require battery capacity large, battery weight accounts for car load about 20%, causes that complete vehicle weight is large, oil consumption is high; It is excessive that motor size is large, how number of batteries also causes whole drive part to take up room, and is unfavorable for that the space controls installation.The advantage of motor+two～fourth gear AMT formula is good dynamic property, and capacity motor and size all can be smaller.But the automatical control system more complicated, and there is large, the flimsy problem of load in the synchronizer among the AMT.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Novel pure electric bus dedicated transmission is provided, it is little, lightweight that it has a volume, fuel-economizing economize on electricity, the advantage that applicable working condition is wide.
The present invention solves its technical problem and takes following technological scheme to realize:
A kind of Novel pure electric bus dedicated transmission, it is characterized in that: by shell and installation motor in the enclosure, main shaft, the first planet row, the second planet row, third planet row, the first break, second brake, the 3rd break consists of, the first planet row, the second planet row, third planet row is by separately sun gear, planet wheel, planet carrier and gear ring consist of, the first planet row, the second planet row, third planet row's sun gear all is connected by main shaft with the rotor of motor, the gear ring of the first planet row is connected with the planet carrier of the second planet row, the gear ring of the second planet row is connected the first planet row with third planet row's planet carrier, the second planet row, third planet row's gear ring respectively with the first break, second brake and the 3rd break are corresponding to be installed.
Advantage of the present invention and good effect are:
Scientific structure design of the present invention is reasonable, adopt three groups of single planetary rows of driven by motor to carry out transmission, the small motor of realizing speed reducer drives, can adopt the motor of small capacity, small volume can realize job requirement, can reduce simultaneously volume and the weight of required outfit battery pack, thereby make speed changer structure compacter, play and reduce to take up room, and the effect of economize on electricity fuel-economizing; And, having the three class gear shift function, applicable working condition is in extensive range, and the automatical control system that is complementary with break is simple; Adopting motor driving, by control current of electric size, also can realize electrodeless variable-speed in certain speed range, is a kind of pure electric bus speed changer with higher innovation, has market popularization value.

Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of Novel pure electric bus dedicated transmission, it is made of shell 1 and installation motor 2, main shaft 18, the first planet row, the second planet row, third planet row, the first break 12, second brake 8, the 3rd break 5 in the enclosure.The first planet row, the second planet row, third planet row consist of by sun gear, planet wheel, planet carrier and gear ring, and planet wheel is installed on the planet carrier and engagement is installed between sun gear and the gear ring.The first planet row is made of sun gear 17, planet wheel 14, planet carrier 15 and gear ring 13.The second planet row is made of sun gear 16, planet wheel 10, planet carrier 11 and gear ring 9.Third planet row be made of sun gear 3, planet wheel 4, planet carrier 7 and gear ring 6.Ratio coverage 5.667 ~ 1.00.
The first planet row, the second planet row, third planet row's sun gear all is connected by main shaft with the rotor of motor, the gear ring of the first planet row is connected with the planet carrier of the second planet row, the gear ring of the second planet row and third planet row's planet carrier is connected, the gear ring that the first planet row, the second planet row, third planet are arranged respectively with the corresponding installation of the first break, second brake and the 3rd break.
The outside assembly of the first break, second brake and the 3rd break is connected with control system.
Each gear drive path of this speed changer is:
A shelves: the first arrester close.This moment, the gear ring 13 of the first planet row was locked, transmission of power: motor 1 → sun gear 17 → planet wheel 14 → planet carrier 15 → output.Be used for starting, ramp, need the driving cycle of high pulling torque.
The B shelves: second brake is closed.This moment, the gear ring 9 of the second planet row was locked, transmission of power: the planet carrier 15 of motor 1 → sun gear 16 → planet wheel 10 → planet carrier 11 → the first planet rows → first planet row → output.Be used in the city driving cycle or occupant less the time.
C shelves: the 3rd arrester close.This moment, third planet row's gear ring 6 was locked, transmission of power: planet carrier 15 outputs of motor 1 → sun gear 3 → planet wheel 4 → planet carrier, 7 → the second planet rows and the first planet row → first planet row.Be used for outskirts of a town, expressway around city road driving cycle.
