The use of environmentally friendly materials in the design of new energy vehicles greatly reduces the pollutant emissions in the operation of the vehicle.
At present, China has focused on the research of new energy vehicles, and has been proposed as an emerging industry.
1. The development of automobile chassis technology in the early days, through certain improvements, the bicycle parts have been transformed into the design of new energy vehicles using environmentally friendly materials, which greatly reduces the emission of pollutants in vehicle operation.
At present, China has focused on the research of new energy vehicles, and has been proposed as an emerging industry.
Therefore, this paper will discuss the chassis structure design of new energy vehicles.
New energy vehicles are different from traditional cars in the use of power energy. Traditional cars basically use diesel and gasoline, while new energy vehicles use renewable environmental energy, such as solar energy, natural gas and liquefied petroleum, etc.
China’s new energy vehicles mainly for electric vehicles.
According to the different types of energy used by electric vehicles, electric vehicles can be divided into pure electric vehicles, fuel electric vehicles and battery energy storage electric vehicles.
2.1 Use of traditional vehicle chassis design platform In the process of chassis design of new energy vehicles, the design framework of traditional vehicle chassis should be used as far as possible, such as chassis frame, suspension system, steering system, braking system, etc.;
In other details to improve the fine tuning, such as the front and rear axle load distribution, front and rear braking force distribution.
This can not only save research and development expenses, but also shorten the time of research and development.
2.2 Canceling the traditional fuel engine because the traditional automobile powertrain will be replaced by a new type of powertrain, that is, the powertrain of engine, transmission and retarder will be replaced by the powertrain of power battery and motor.
Therefore, the chassis design of new energy vehicles needs to make some adjustments on the basis of the traditional vehicle chassis, such as adding electric steering booster oil pump, electric air compressor, etc., to meet the power source demand of power steering system, braking system, air suspension and other related subsystems.
Compared with the traditional automobile power system, the new type of power system change is bigger, need scientific adjustment of piping, wiring harness and other related parts, when the components of each subsystem design is completed, need according to the arrangement of the chassis overall checking, to improve the strength of the bracket, suspension system, and reduce the noise.
