摘要： 在中国大学生方程式赛车（FSC）中，变速机构通常采用集成于发动机内部的变速箱。 为实现换挡机构的轻量化与集成化，基于车队在换挡系统中的实际应用经验，文章设计了一 种以舵机为核心，结合机械控制单元与电子控制单元的电动换挡机构。借助 CATIA 建模软件 完成了机械结构的设计与建模，通过舵机驱动换挡杆执行换挡操作。与手动换挡和电控气动 换挡相比，舵机换挡结构具有质量轻、集成度高、便于维护等优势，更加适用于 FSC。该技 术不仅进一步提升了赛车的轻量化水平，也为换挡系统的研究与创新设计提供了新思路。

Abstract: In formula student China (FSC), the transmission mechanism typically utilizes a gearbox integrated within the engine. To achieve lightweight and integrated design of the shifting mechanism, this study designs an electric shift system centered on a servo mechanism, combining mechanical and electronic control units, based on the team's practical experience with shift systems. The mechanical structure is designed and modeled using CATIA software, enabling shift operation through servodriven control of the shift lever. Compared to manual and electro-pneumatic shift systems, the servo shift mechanism offers advantages such as reduced weight, high integration, and ease of maintenance, making it particularly suitable for FSC. This technology not only further enhances the lightweight performance of the vehicle but also provides new insights for the research and innovative design of shift systems.
