"北京吉普BJ40汽车循环球式转向器设计与三维建模"

Recirculating ball steering gear is the most widely used type of steering gear in automobiles due to its numerous advantages, such as low friction, high transmission efficiency, long service life, and ease of operation. This design project focuses on the development of key components of the recirculating ball steering gear for the Beijing Jeep BJ40 model in accordance with national standards and automotive design principles. By leveraging the relevant parameters of the BJ40 model, a recirculating ball steering gear that meets the specific requirements of the vehicle is designed. The project includes the creation of a three-dimensional solid model and the generation of two-dimensional engineering drawings for the steering gear. This design project not only contributes to the enhancement of automotive safety but also showcases the practical application of engineering principles in the development of innovative automotive technologies._KEYWORDS: Recirculating ball steering gear; design; three-dimensional modeling; Beijing Institute of Technology Zhuhai College 2020 undergraduate graduation project.
