Abstract
Drive axle is one of the most important parts of automobile. The function is to increase the torque from drive shaft or from transmission directly, and then distribute it to left and right wheels which have the differential ability automobile needed when driving. And the drive axle has to support the vertical force, longitudinal force, horizontal force and their moments between road and frame or body. Its quality and performance will affect the security, economic, comfortability and reliability.
This article analyzes and refers to the drive axle of Jianghuai HF15015 truck and the 468 drive axle of Hyundai seriously. Through the study of this topic, we can design the single driving axle devices that apply to the heavy truck with high-powered engine, and make sure the drive axle we design of heavy truck economic, practical, safe and reliable. On talking about the running principal of driving axle ,the three key techno ledge about vehicle traveling on the ride and through, and noise reduction technology applications and the standardization of parts, components of the universal, Products such as the serialization that we should master to meet, it describes and has a systematic analysis on the basic principles of viecle drive axle.
According to the design principles and analysis and comparison of economy, application, comfortability, safety and reliability , the heavy truck drive axle structure, layout ways, and the final drive assembly, differential assembly, the bridge case and axle structure can be determined; and the strength checking of brake parts, as well as major components improves overall design of the driving axle.
Through the study of this topic, we can design the single drive axle devices that apply to the heavy truck with high-powered engine, and make sure the drive axle we design of heavy truck economic, practical, safe and reliable.
