【摘要】 汽车驱动桥一般由主减速器、差速器、四轮驱动装置和传动桥壳等组成,是汽车的主要部件之一。它主要具备的基本功有是增加变速箱或者传轴上的扭矩,合理地将扭矩分别配置到左边和右边的驱动轮上面,让两个驱动轮在车辆行驶的过程中具有达到需求量的差速功能。此外,汽车的驱动桥还要承受整个车身的重量作用于地面时的一些作用力,比如垂直力,纵横向力、还有扭矩。所以,汽车驱动桥在汽车的整个构成部件中十分重要,它的制作工艺的优劣,质量的好坏一定程度上直接影响着我们使用车辆时的安全性和乘坐车辆的舒适性。本次研究我们选择了现实生活中比较常见的交叉型乘用车辆为研究群体,主要研究后驱动桥总成的通气塞设计及优化;后桥壳总成的结构及优化;后驱动桥总成的密封性检测,实现车辆密封性提高的目的。本文主要研究汽车后驱动桥通气装置及后桥壳的密封优化以及制造影响因素,对后驱动桥总成的通气塞设计优化和后桥壳总成的制造工艺等进行理论分析,以此为基础对后驱动桥总成的通气塞设计、后桥壳总成的结构、桥壳的制造进行优化,实现通过制造工艺优化和结构改造,达到提升后驱动桥总成密封性的目的,同时优化后驱动桥总成密封性检测方式,提高劳动生产率。更多还原

【Abstract】 The automobile drive axle is generally composed of a main reducer,a differential,a four-wheel drive device,and a transmission axle housing,and is one of the main components of the automobile.The basic functions it has are mainly to increase the torque on the transmission or the transmission shaft,and to rationally distribute the torque to the left and right driving wheels,so that the two driving wheels can achieve the required differential speed during the driving of the vehicle.Features.In addition,the driving axle of the car also has to bear some forces such as vertical force,vertical and horizontal force,and torque when the weight of the entire vehicle body acts on the ground.Therefore,the automobile drive axle is very important in the entire component parts of the automobile.The pros and cons of its production process and the quality of the automobile directly affect the safety of our use of the vehicle and the comfort of the vehicle.In this study,we chose the common crossover vehicle as the research group,and studied the design and optimization of ventilators for the rear drive bridge assembly.Structure and optimization of rear bridge shell assembly;The sealing of the rear drive bridge assembly is tested to improve the vehicle seal.This paper studies the automobile driving factors of sealing optimal design and manufacture effect of bridge shell bridge ventilation device and a ventilation plug,to design and manufacture and installation and the rear axle assembly of the machining process is analyzed,on the basis of the rear drive manufacturing process design of ventilation plug axle assembly manufacturing and bridge structure parameters the shell is optimized and realized to ascend through the improvement of structure and manufacturing process optimization of drive axle assembly sealing purposes,while optimizing the drive sealing detection way assembly bridge,improve labor productivity.更多还原
