Technical field
The utility model relates to the electronlmobil field, relates in particular to a kind of electric drive system.
Background technology
At present; along with environmental protection and energy problem are more and more paid close attention to, developing of automobile industry begin gradually from traditional only rely on driving engine as combustion engine epoch of drive source to the hybrid power epoch transition of disposing motor and two kinds of drive sources of driving engine simultaneously.This hybrid vehicle can be selected arbitrarily to drive simultaneously by motor or by driving engine or by the two in motion, makes vehicle needn't rely on driving engine fully, has therefore realized energy-conservation and environmental protection to a certain extent.
Yet, owing to still continuing to use the engine installation and the transmission mode of traditional combustion engine automobile in this hybrid electric drive system, therefore cause messenger chain oversize, driving efficiency is low, complex structure, and still can't break away from engine drive fully, therefore also just can't realize energy-conservation fully and purpose environmental protection.
The utility model content
The utility model can't be realized energy-conservation and shortcoming environmental protection in order to overcome hybrid electric drive system fully, and a kind of electric drive system of energy-conserving and environment-protective is provided.
A kind of electric drive system of the present utility model, wherein, this system comprises: the motor with stator and rotor, box of tricks, the internal gear group that comprises first gear and second gear, semiaxis and wheel, the rotor of motor has hollow structure, described box of tricks is arranged in described hollow structure, described box of tricks comprises first rotating element, second rotating element and the 3rd rotating element, described first rotating element links to each other with the rotor shaft of motor, first rotating element is a pinion carrier, described internal gear group is positioned at the wheel hub of wheel, described second gear is captiveed joint with wheel hub, and described second rotating element links to each other with described first gear by semiaxis respectively with the 3rd rotating element.
Electric drive system of the present utility model is pure electric drive system completely, therefore can realize energy-conserving and environment-protective; Simultaneously, because this drive system has been omitted traditional structures such as change-speed box, also has simple in structure, driving efficiency advantages of higher.
Description of drawings
Fig. 1 is a kind of embodiment structural representation of the utility model electric drive system.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
According to a kind of embodiment of the present utility model, as shown in Figure 1, a kind of electric drive system, wherein, this system comprises: the motor 7 with stator and rotor, box of tricks 6, the internal gear group that comprises first gear 3 and second gear 2, semiaxis 9 and wheel 1, the rotor of motor 7 has hollow structure, box of tricks 6 is arranged in hollow structure, box of tricks 6 comprises first rotating element 8, second rotating element 4 and the 3rd rotating element 5, first rotating element 8 links to each other with the rotor shaft of motor 7, first rotating element 8 is a pinion carrier, the internal gear group is positioned at the wheel hub of wheel 1, second gear 2 is captiveed joint with wheel hub, and second rotating element 4 links to each other with first gear 3 by semiaxis 9 respectively with the 3rd rotating element 5.
Second rotating element 4 can be left half axle gear or right axle shaft gear, and the 3rd rotating element 5 can be right axle shaft gear or left half axle gear.
As a kind of embodiment, second rotating element 4 is a left half axle gear, and the 3rd rotating element 5 is the right axle shaft gear.Left and right sides axle side gear links to each other with first gear 3 by semiaxis 9 respectively, the semiaxis 9 that is left half axle gear by the left side links to each other with first gear 3 of the wheel that is positioned at the left side, the right axle shaft gear links to each other with first gear 3 of the wheel that is positioned at the right side by the semiaxis 9 on right side, driving first gear 3 thus rotates, and then drive 2 rotations of second gear, thereby powered vehicle is travelled.
Further, many these drive systems of group can be set according to actual needs, for example common 4 wheeled vehicles, two front-wheels can be used this drive system, and two trailing wheels are common wheel; Also can adopt this drive system respectively in front and back, promptly realize 4 wheel drive.
The internal gear group comprises that intermeshing first gear 3 and second gear, 2, the first gears 3 link to each other with semiaxis 9, and second gear 2 is positioned at the wheel hub (not shown) of wheel 1 and captives joint with wheel hub.This internal gear group can play to slow down and increase the effect of turning round.
Convenient for processing and fabricating, first gear 3 can be made into integration with semiaxis 9, and second gear 2 is shaped with the wheel hub integral production.
Foreign material such as sewage, silt enter the internal gear group when preventing vehicle ', further, also are provided with hermetically-sealed construction at the two ends of wheel hub, the lid hermetically-sealed construction can be a plectane, by being bolted to the two ends of wheel hub, also have circular hole on the plectane, pass through to make things convenient for semiaxis 9.
The utility model can adopt broken drive bridge and independent suspension as required, perhaps adopts rigid drive axle and dependent suspension, further, can also adopt universal-joint to be connected with first gear 3 with box of tricks 6 at the two ends of semiaxis 9.
Because the utility model is arranged on box of tricks 6 in the motor 7 with hollow structure, and the left and right sides axle side gear of box of tricks 6 directly is connected in one group of internal gear by semiaxis 9, this internal gear group is arranged in the wheel hub, thereby effectively utilized the space at wheel 1 place, and then simplified the structure of drive system, improve driving efficiency, helped reducing the cost of drive system.Simultaneously, because this drive system is a pure electric drive system, thereby can realize energy-conserving and environment-protective.
