Automobile rear axle drive after as a key component, its quality has important influence on the safety of the vehicle performance, thus to optimize the mechanics of the major components analysis and design is very necessary, automobile driving axle withstand shock at run time, the effect of repeated bending and torsional stress, so must be high enough for flexural strength, fatigue strength and good toughness.

Structure and design parameters of automobile rear axle in addition to have important influence on automobile reliability and durability, and performance of vehicles, such as performance, fuel economy, comfort, through sex, mobility and maneuverability, etc have a direct impact, therefore, the structure of the automobile rear axle type selection, design parameter selection and design calculation of motor vehicle design is extremely important.

In today's rapid economic development, the production technology, design and development of the automobile rear axle must closely rely on the reality of scientific production, only to master the latest production technology, to create the high quality of automobile rear axle products, to meet the market demand, develop the automobile rear axle products to satisfy the needs of the consumers.

Automobile rear axle of vehicle structure, assembly, production technology, using performance, safety, etc all have important influence, therefore it is important to pay special attention to when processing, the production technology of automobile rear axle must be as the key link to control, in improving the quality of the vehicle at the same time, but also fully take into account factors such as production technology conditions and quality cost, so that you can fully improve the comprehensive efficiency of automobile rear axle production.

The quality inspection standards for automobile rear axle need combined with the production technology condition and the use of performance requirements, such as car body for different types and models of automobile rear axle should formulate quality standard, if there is a dimensional deviation is, given the problems in the design, planning and other craft level is unavoidable in the production, but the size of the deviation directly determine the appearance of the vehicle, and the matching degree of automobile driving axle installation, parts and components such as quality level.

The raw materials used for processing the rear axle of the automobile must conform to the specified technical conditions, and the dimensional accuracy and surface quality should be inspected. All links specified in the process specification should be fully and strictly observed, and comprehensive inspection should be carried out. Only after qualified inspection can the automobile be put into production.
