1、标准文案摘要驱动桥处于汽车传动系统传动系的末端，其基本功能是增大由传动轴或变速器传来的转矩，并将动力合理地分配给左、右驱动轮，另外还承受作用于路面和车架或车身之间的垂直力，纵向力和横向力。在一般的汽车结构中驱动桥一般由主减速器，差速器，车轮传动装置和驱动桥壳等组成。本次驱动桥设计应满足如下基本要求：1．所选择的主减速比应能保证汽车具有最佳的动力性和燃料经济性。2．驱动桥轮廓尺寸不大，以便于汽车的总布置及与所要求的驱动桥离地间隙相适应。3．齿轮及其它传动件工作平稳，噪声小。4．在各种转速和载荷下具有高的传动效率。5．驱动桥各零部件在强度高，刚行好，工作可靠及使用寿命长的条
2、件下。6．与悬架导向机构运动协调，对于转向驱动桥，还应与转向机构运动相协调。7．驱动桥总成及零部件的设计应尽量满足零件的标准化，部件通用化和产品的系列化及汽车变形要求。8.结构简单，加工工艺好，制造容易，拆装，调整方便。关键词：后桥，差速器，后桥壳，设计。大全标准文案AbstractThedrivingaxleisintheautomobiletransmissionsystempowertransmissiontheterminal,itsbasicfunctionincreasesthetorquewhichtransmitsbythedriveshaftorthe
