设计简介
摘 要
随着人们生活水平的提高，能源节约、环境保护问题日趋严重，人们的关注程度也越来越高。
本文以中国节能竞技车大赛为背景，以本校已有的竞技车为基础。同时整个设计在满足大赛要求的基础上，以省油为主要指导思想，减少竞技车复杂程度和轻量化。本次设计对竞技车的转向系、传动系和离合器进行改进设计。论文首先对竞技车的总体方案进行了确定。然后对转向机构进行设计，运用CATIA对其进行实体建模，同时利用CATIA的运动仿真对转向系进行了仿真模拟运动，验证了转向机构的合理性。通过对相关期刊的研读，通过其中大量的实车试验数据，确定了传动系传动方案为链传动，也确定了离合器的改进方案。

ABSTRACT
As people's living standards improve, energy conservation and environmental protection are becoming more and more serious, and people are becoming more and more concerned.
Energy saving in China based on competitive car competition as the background, on the basis of our existing sports car.At the same time, the whole design is on the basis of satisfying the requirements of the competition, which is the main guiding principle of oil saving, reducing the complexity and light weight of the competitive vehicle.This design is designed to improve the steering, transmission and clutch of competitive vehicles.The paper first identified the overall scheme of competitive vehicles.And then to design of steering mechanism, using CATIA to entity modeling, at the same time, using CATIA movement simulation of steering system has carried on the simulation, the rationality of the steering mechanism was verified.Through the study of related journals, through which a large number of real vehicle test data, determine the drivetrain transmission scheme for the chain, also identified the improvement scheme of the clutch.
Key Words：Write Criterion; Typeset Format; Dissertation；CATIA 3 d modeling
