摘要
近几年来,因为环境的污染变得越来越严重,电动车这一领域逐渐得大家的关注的支持,而在近几年,电子商务的急速发展的,使得电商物流得到了快速的发展,电商物流的流量急剧增长,所以电动物流车也成了这一领域的重要分支之一,在专用车领域占很大的比例。并且在城市里面的污染也变得越来越严重的情况下,一种新型交通工具—纯电动物流车,逐渐得到的政府大力推广。电动汽车丝毫没有污染排放,并且稳定性大于传动的内燃机汽车,在经济性方面也有明显的优点。此外,驱动桥作在纯电动物流车中作为传动系统的重要部分,在电动汽车的结构中有着非常重要的作用。驱动桥的构造和驱动形式以及驱动桥的安放对整车的动力性和经济性有很大的影响,本文主要是针对在现有轻型货车驱动桥的基础上进行改进,将传统的轻型物流车的驱动桥与驱动电动机结合,通过在结构以及传动形式上的改进,对驱动桥的传动部分产生较大的影响,电动物流车驱动桥的设计对于电动物流车的形式动力性和经济性的部分提高有着重要的设计以及指导意义。
论文主要根据电动汽车的设计要求,参考相关书目和设计标准,分析驱动桥的结构形式布置形式以及驱动形式,并且对驱动桥的减速齿轮差速器半轴等结构进行参数的计算,然后进行校核,最后运用CATIA进行驱动桥的建模,并对所建的模型进行理论分析,分析受力情况以及形变等,然后用有限元软件进行仿真,以查看设计所得结构是否满足设计所需要求。
研究结果表明:设计的新型电动物流车的驱动桥的满足题目中给的条件要求。
本文的特色:参考相关标准进行设计并建模,最后用有限元软件分析。

Abstract
In recent years, due to more and more serious environmental pollution, electric vehicles in this area gradually get everyone's favor, and in the rapid development of e-commerce under the strong pull, electricity business logistics to maintain a sharp growth, so the electric logistics car has become One of the important branches of this field, in the field of special vehicles accounted for a large proportion. And in the case of urban pollution more and more serious, pure electric vehicle traffic car has gradually become a new type of transport vehicles, electric vehicles with zero pollution emissions, the advantages of high economic advantages, and the driving stability of the noise is small, and the drive axle in the electric Automobile power transmission accounted for an important proportion of the drive axle structure and drive the form and layout of the car will have a great impact on the power and economy, this paper is mainly for the existing light truck drive bridge on the basis of The design of the drive axle of the traditional light logistics vehicle has a great influence on the transmission efficiency of the drive axle through the improvement of the structure and function. The design of the electric vehicle driving axle is the dynamic and economical Sexual promotion has important guiding significance.
Based on the design requirements of the electric vehicle, the paper analyzes the structure and the driving form of the drive axle with reference to the relevant bibliography and design standards, and calculates the parameters of the axle of the reduction axle of the drive axle, Core, and finally use CATIA to carry on the modeling of the driving axle, and carry on the theoretical analysis to determine the force situation, then uses the finite element software to carry on the simulation to see whether the designed structure satisfies the design request,
The results show that the design of the new electric vehicle driving axle meets the requirements.
The characteristics of this article: reference to the relevant standards for design and modeling, and finally with finite element software analysis.
Key Words:electric vehicle; driving axle; CATIA; finite element analysis
