1、汽车后桥壳设计毕业论文摘要汽车后桥壳是汽车的重要组成部分,它与主减速器、差速器和车轮传动装置组成驱动桥。驱动桥处于动力传动系的末端,其机动功能是增大由传动轴或变速器传来的转矩,并将动力合理的分配给左、右驱动轮,另外驱动桥桥壳是汽车上重要的承载件和传力件。驱动桥的桥壳不仅支承汽车重量,将载荷传递给车轮,而且还承受由驱动车轮传递过来的牵引力、制动力、侧向力、垂向力的反力以及反力矩,并经悬架传给车架或车身。在汽车行驶过程中,由于道路条件的千变万化,桥壳受到车轮与地面间产生的冲击载荷的影响,可能引起桥壳变形或折断。因此,驱动桥壳应具有足够的强度、
2、刚度和良好的动态特性,合理地设计制造驱动桥壳是提高汽车行驶稳定性的重要措施,汽车后桥壳广泛应用于各种车辆当中。所设计的后桥壳夹具可广泛应用于卡车的后桥壳加工中,后桥壳起保护和支撑的作用,其主要加工表面为端面外圆、法兰平面、弹簧座平面、以及内孔等。本次设计的内容主要包括机械加工工艺规程、夹具的设计。结合本次设计零件的特点,在设计中完成工艺规程一套,夹具一套。铣床夹具,采用手动夹紧。通过对汽车后桥壳夹具的学习和设计,可以更好的学习并掌握现代夹具设计与机械设计的全面知识和技能。关键词:汽车后桥;工艺规程;夹具AbstractAutomobile
