CR-V轿车分动器设计.doc

摘要
汽车若在冰雪路面或无路的情况下行驶时,就要求增加驱动车轮的数目,以充分利用汽车的重量来增加车轮与道路间的附着力。分动器的主要功用是将发动机输出的动力分配到各驱动桥,并且进一步增大扭矩;其另一个功用是兼起副变速器的作用。分动器也是一个齿轮传动系统,它单独固定在车架上,其输入轴与分动器的输出轴用万向传动装置连接,分动器的输出轴有若干根,分别经万向传动装置与各驱动桥相连。
本设计根据匹配车型的使用条件和车辆参数选择分动器的结构形式,并按照分动器总成的设计步骤和要求,对其主要零部件,如齿轮、轴进行了相关的设计工作和校核工作。并根据汽车设计、汽车理论、机械设计、机械设计课程等参考资料提供的相关知识,对计算出的分动器具体参数进行检验,并论证设计的合理性。最终,用AutoCAD软件完成分动器二维装配图和零件图的绘制。

ABSTRACT
If car drive in snow and ice road or no way under the condition of the road, it’s to ask for an increase in the number of driver wheels,To take full advantage of the weight of the car to increase the wheels and the adhesion between road,The main function is to thansfer engine output power distribution to the driving axle, and further increase torque, the other a function is and the deputy variable is also a gear transmission system, it alone in frames, the fixed input shaft and thansfer output shaft with universal transmission devices connected, thansfer output shaft several root, the universal respectively with each drive transmission device connected.
This design according to the conditions of use and matching model vehicle parameter selection of structure form, and thansfer according to the design procedures of the assembly thansfer and requirement, for its main parts, such as gear, the shaft related design work and check work. And according to the car design, car theory, mechanical design, mechanical design courses provide reference information for the relevant knowledge, calculated from the concrete parameters for inspection, thansfer and demonstrates the rationality of the design. Finally, with AutoCAD software thansfer 2 d assembly drawings ponent drawing.
