Description
Technical field
It the utility model is related to automobile, more particularly to a kind of New-energy electric vehicle.
Background technology
The crane span structure of automobile is by vehicle frame, the back axle of support vehicle frame（Drive axle）And automobile front axle（Also known as propons, it is steeraxle）
Form, the both ends of drive axle and front axle all connect wheel, and vehicle frame is connected on vehicle frame by hitch.
It is initial with engine（Gasoline engine or diesel engine）For core drive, i.e. using fuel oil as power, realize vehicle just
Often traveling.But as long as the startup of fuel power automobile vehicle one will consume the non-renewable energy（Gasoline or diesel oil）Give ring simultaneously
Cause considerable degree of pollution in border.
First, fuel（Automobile）The characteristics of vehicle and the harm of vehicle exhaust
1st, substantial amounts of toxic and harmful gas is contained among vehicle exhaust, this is most directly and most obvious.People in city
Mouthful density is big, and the quantity of car is also more, and emission is also just more, it is easier to cause human body to be directly sucked in a large amount of tail gas, be human body by
Frustrate, give rise to diseases, even result in the death of people.
2nd, it is exactly to allow the people of no driving efficiency to grasp this technical ability, the completely people without driving efficiency the characteristics of learner-driven vehicle
When driving efficiency is learnt, it will necessarily practise for a long time on learner-driven vehicle, automatic catch automobile engine long-play, by
Shift hunting during driving technology is not practised fortunately can impact to caused by gearbox, cause power shift gear to damage, such as
Do not shift gears and engine burn oil can be caused serious, tail gas severe overweight, the carbon dioxide given off is also multiplied, so not
Only the body and mind of student in exercise floor and coach are damaged.Also greenhouse effects have more been aggravated.
3rd, the tail gas of discharge is more, it was demonstrated that Che Yeduo, the gasoline or diesel oil used are also more.The earth is not a resource in fact
Abundant home, and China is even more gasoline country in short supply, this undoubtedly adds national burden.Moreover, with vehicle exhaust
A large amount of discharges, haze weather are also increasingly apparent.
Carry out the research and development of new-energy automobile for this, it is the most ripe with electric vehicle engineering in new-energy automobile.
Existing New-energy electric vehicle has the following disadvantages：It is to use existing fuel-engined vehicle to carry out during anticollision design
Structure, that is, set and be connected to front/rear collision bumper on vehicle frame and carry out anticollision, therefore not only anti-side impact ability but also produce is touched
