摘要
万向传动装置是汽车传动系中的重要总成,它直接与变速器和驱动桥相联系,用来实现对传动系的动力传递。课题研究对象是后轮驱动广泛应用的十字轴式万向传动装置,主要零件包括传动轴、万向节、支撑装置等,这些关键零部件的设计对整个万向传动装置性能具有很大的影响。
本文主要是对汽车的十字轴式万向传动装置进行设计。根据车辆使用条件和车辆参数,按照传动系统的设计步骤和要求,主要进行了以下工作:选择相关设计参数主要为:十字轴、万向节、传动轴、中间支承的参数确定,并进行了总成设计主要为:十字轴的设计,万向节的设计、传动轴的设计以及中间支承的设计等。并通过有限元ANSYS软件对设计万向传动装置进行结构分析,根据分析结果对万向传动装置进行改进优化设计并得出合理的设计方案。在传动轴的设计中采用有限元技术研究这些关键零部件的静力学特性,对其结构进行优化设计,可以大大缩短万向传动装置总成开发周期、降低开发费用,提高设计质量,保证其设计的精确性。

ABSTRACT
Universal transmission is important in automobile transmission assembly, which directly linked to transmission and drive axle, used to achieve the transfer of the power transmission system. Research object is widely used in rear-wheel drive transmission cross shaft universal, the main parts including drive shafts, universal joints, support devices, the design of these ponents for the universal transmission has a great influence on the performance .
This article mainly is carries on the design to the automobile cross shaft type rotary transmission device. According to vehicles exploitation conditions and vehicles parameter, according to transmission system design procedure and request, Mainly has carried on following work: Mainly has carried on following work choice correlation design variable mainly is: Cross axle, universal joint, drive shaft, middle supporting parameter determination, and has carried on the unit design mainly is: Cross axle design, universal joint design, drive shaft design as well as middle supporting design and so on. And to designs the rotary transmission device through the finite element ANSYS software to carry on
