狮跑汽车后桥机械设计CAD图纸及论文——驱动效能与设计方案详解

The driving axle assembly is an essential component of a vehicle, directly impacting its performance and lifespan. It typically consists of the main reducer, differential, semi-axle, and axle housing. The main function is to increase the torque transmitted from the transmission shaft or gearbox, distribute it to the left and right wheels, and provide the necessary differential function for the vehicle to operate smoothly. Additionally, it must withstand vertical, longitudinal, and lateral forces between the road surface and the vehicle frame or body. This undergraduate mechanical design project focuses on the design of the driving axle assembly, with a particular emphasis on the main reducer, differential, semi-axles, and axle housing. The overall design scheme includes the use of an integrated driving axle assembly with a single-stage main reducer featuring spiral bevel gears, a differential with conical planetary gears, semi-axles with a full-floating design, and an axle housing made from cast integrated castings. Key aspects of the project involve the design and analysis of the single-stage main reducer, conical planetary gear differential, full-floating semi-axles, and the structural verification and material selection for the axle housing. The use of computer-aided design (CAD) technology facilitates the detailed design process and ensures the accuracy and efficiency of the project. In conclusion, this undergraduate mechanical design project provides a comprehensive overview of the design and analysis of a driving axle assembly for a vehicle, focusing on key components such as the main reducer, differential, semi-axles, and axle housing. The project emphasizes the importance of a well-designed and optimized driving axle assembly for enhancing vehicle performance and longevity.
