1、 本科学生毕业设计 轻型商用车传动轴及万向节设计 系部名称： 汽车工程系 专业班级： 车辆工程 B05-18 班 学生姓名： 指导教师： 职 称： 二九年六月 The Graduation Design for Bachelors Degree Design of Light Commercial Vehicle Transmission Shaft and Cardan Joint I 摘 要 汽车的万向传动轴是由传动轴、万向节两个主要部件联接而成，在长轴距的车辆 中还要加装中间支承。 万向传动轴主要用于工作过程中相对位置不断改变的两根轴间 传递转矩和旋转运动。在本世纪初万向节与传动轴的发明

2、与使用，在汽车工业的发展 中起到了极其重要的作用。 随着汽车工业的发展， 现代汽车对万向节与传动轴的效率、 强度、耐久性和噪声等性能方面的设计及计算校核要求也越来越严格。本毕业设计将 依据现有生产企业在生产车型(CA1041)的万向传动装置作为设计原型。在给定整车 主要技术参数以及发动机、变速器等主要总成安装位置确定的条件下，对整车结构进 行了分析，确定了传动轴布置方案，采用两轴三万向节带中间支承的布置形式。在确 定了传动方案后，对传动轴、万向节总成、中间支承总成进行设计，使该总成能够在 正常使用的情况及规定的使用寿命内不发生失效。 关键字：传动轴；万向节；中间支承；设计；校核 II ABST

3、RACT The universal drive shaft of automotive is composed of transmission shaft and cardin joint. The main function of the universal drive shaft is to transmitting torque and rotation movement between two shafts whose relative position is variation in the working process. At the beginning of this cen

4、tury the transmission shaft and cardin joint play an important role in the development of automobile industry. As the development of automobile industry, the automobile demand that the design and verification of transmission shaft and cardin join stricter in the efficiency, intension, durability and

5、 noise performance. This graduation design chooses existing production business enterprise of basis is producing the car type(CA1041) of ten thousand to spread to move to equip the conduct and actions design prototype. Under the conditions of the main technical parameters of the given vehicle, insta

6、llation location of engine, transmission and other major assembly are determined , the structure of the vehicle is analysised, the transmission shaft layout program is determined. Two shaft-three cardin joints is adapted. After determining the transmission options, the right drive shaft and universal joint assembly, intermediate bearing assembly is designed, so that the assembly can be used in normal situations and the life within no failure.
