PAGE V PAGE 中型轿车驱动桥设计 摘要 今天，节能环保已成为世界共识。世界汽车的发展方向将继续朝着更加节能环保的微型化方向发展。前驱动汽车在小型和经济型汽车上很流行。前车架的布局通常被设置在引擎的横向方向，连接到紧凑的转化步骤。省略其车轴，紧凑地有效利用引擎房间的空间。它的内部空间是更宽敞的，有助于减少地板的高度，使其舒适感提高。发动机的动力传递较近，动力传递效率高，燃效性能良好，引擎和其他组装体的前端增加前车轴的负荷，使高速行驶时的稳定性和制动时的方向稳定性、简单的现实悬浮系统等另外，前面的类型有以下缺点。在启动时，在加速时减少前轮的负担，从而减少了阻力。前夫动作不仅是导游的轴，而且还有驱动轴，而且结构复杂，制造成本也很高。、维护和其他的困难。本文分析驱动轴整体的结构，分析现有驱动轴的结构、开发过程、优点、缺点。使用到底型驱动轴，使用主减速机的减速模式。双工器和主收款机被招募，招募者负责使用这个设计，两种产品的设计是双向塑料、齿轮、齿轮、粘合剂、螺旋设计、防水外壳检查和材料选择。 关键词：驱动桥；双级主减速器；弧齿锥齿轮  abstract Today, energy conservation and environmental protection has become a world consensus. The development direction of the world automobile will continue to develop towards more energy saving, environmental protection and miniaturization. Front drive cars are popular in small and economical cars. The layout of the front front car is generally arranged horizontally and connected with the compact variable speed drive bridge. It has the following advantages: by omitting the transmission shaft device to reduce the weight and the structure is compact; the space of the engine room is effectively used, the space between the cab is more spacious and the floor is reduced. The engine is close to the driving wheel, the engine is close to the driving wheel, the power transfer efficiency is high, the fuel economy is good; the engine and other assembly prepositions, increase the load of the front axle, improve the steering stability of the car at high speed and the stability of the direction of the brake, simplify the rear suspension system and so on. On the other hand, front drive type also has the following drawbacks: when starting, accelerating or climbing, the load of the front wheel is reduced and the traction power is reduced; the front axle is both the steering bridge, the driving bridge, the complex structure and process, the high cost of manufacturing, the difficulty of maintenance and so on. The overall structure of the drive bridge is discussed in this paper. On the basis of the analysis of th
