1、汽车后桥是汽车的主耍部件Z-,其基本的功用是增大由传动轴或直接由变速器传来的转矩,再将转矩分配给左右驱动车轮,并使左右驱动车轮具有汽车行驶运动所要求的差速功能:同时,驱动桥述要承受作用于路面和车架或承载车身Z间的铅垂力、纵向力,横向力及其力矩。其质量,性能的好坏直接影响整车的安全性,经济性、舒适性、可靠性。在论述汽车驱动桥运行机理的基础上,提练出了在驱动桥设计屮应掌握的满足汽车行驶的平顺性和通过性、降噪技术的应用及零件的标准化、部件的通用化、产品的系列化等三大关键技术;阐述了汽车驱动桥的基本原理并进行了系统分析;根据经济、适用、舒适、安全可靠的设计原则和分析比较,确定了重型卡车驱
2、动桥结构形式、布置方法、主减速器总成、差速器总成、桥壳及半轴的结构型式。通过本课题的研究,开发设计岀适用于装置大马力发动机重型货车的单级驱动桥产品,确保设计的重型卡车驱动桥经济、实用、安全、可靠。关键字:载重汽车、驱动桥、单级减速桥、弧齿锥齿轮ABSTRACTDriveaxleisoneofthemostimportantpartsofautomobile・Thefunctionistoincreasethetorquefromdriveshaftorfromtransmissiondirectly,andthendistributeittoleftandrightwheelsw
