第1页摘要本次设计的是在SX4180型载货汽车的基础上进行的万向传动轴优化设计。万向传动装置采用可伸缩的花键十字万向传动轴,万向节十字轴轴承盖的设计选择了内卡式的方式定位,油封座圈采用了卡环式的定位方式,万向节凸缘叉的设计参考SX4180型载货汽车的方式设计。文中还对万向传动轴的主要部件进行设计计算和校核,同时阐述了运用 UG软件对万向传动轴三维图的作图方法,以及简单介绍了万向传动装置总成的技术要求和使用保养。关键词:万向节,传动轴第2页 Abstract The design of the SX4180 vehicle on the basis of optimizing the design of the universal drive transmission using scalable cross universal spline shaft, universal joint cross shaft bearing caps with the design chosen the way of cassette positioning, oil seal ring seat ring card using the positioning means, universal joints fork flange design SX4180design for vehicles. The article also ponents of the drive shaft universal design calculations and checking, while the use of MATLAB software universal shaft diameter and diameter to optimize the design of software using the UG shaft universal mapping three-dimensional map. The use of Flash software shaft universal principle of animation, as well as a brief introduction of the universal transmission of the technical requirements for assembly and use of maintenance.
