Description
Technical field
The present invention relates to automobile more particularly to a kind of New-energy electric vehicles.
Background technique
The gantry of automobile is by vehicle frame, the rear axle (drive axle) of support vehicle frame and automobile front axle (bridge, is steeraxle before also known as)
It constitutes, the both ends of drive axle and front axle all connect wheel, and vehicle frame is connected on vehicle frame by suspension mechanism.
Initial is core drive, has been to realize vehicle just using fuel oil as power using engine (gasoline engine or diesel engine)
Often traveling.As long as but the starting of fuel power automobile vehicle one will consume the non-renewable energy (gasoline or diesel oil) while to ring
Cause considerable degree of pollution in border.
One, the characteristics of fuel (automobile) vehicle and the harm of vehicle exhaust
1, contain a large amount of toxic and harmful gas in vehicle exhaust, this is most directly and most apparent.People in city
Mouthful density is big, and the quantity of vehicle 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
It frustrates, gives rise to diseases, even result in the death of people.
It 2, is exactly that the people of not no driving efficiency is allowed to grasp this technical ability, the absolutely not people of driving efficiency the characteristics of learner-driven vehicle
When learning driving efficiency, it will necessarily practice on learner-driven vehicle for a long time, automatic catch automobile engine long-play, by
Shift hunting during driving technology is not practiced fortunately can be impacted caused by gearbox, cause power shift gear to damage, such as
It does not shift gears and to will lead to engine burn oil serious, tail gas severely exceeds, and 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.
3, the tail gas discharged 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
Home abundant, and China is even more gasoline country in short supply, this undoubtedly increases 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 thus, it is the most mature with electric vehicle engineering in new-energy automobile.
For using existing fuel-engined vehicle when existing New-energy electric vehicle has the disadvantage that progress anticollision design
Structure, i.e. the front/rear collision bumper that is connected on vehicle frame of setting carries out anticollision, therefore not only anti-side impact ability is poor but also generation is touched
Vehicle frame can be squeezed when hitting and leads to frame distortion, and frame distortion is then easy to damage occupant and/or cargo.
Summary of the invention
