It is of great significance to design a central brake reducer to meet the requirements of Baja racing car and pursue lightweight, so as to solve the problems of single structure, high cost and low trans-mission efficiency of the self-made reducer of Baja racing car in the current market. This paper analyzes the design concept of Baja racing car reducer, determines the design goal and overall design of the central brake reducer, uses CATIA drawing software to design the central brake deceleration parts, topological optimization of the key parts of the central brake reducer, to achieve the light-weight design goal. The function and power transmission route of reducer are introduced, and the lubrication and sealing of reducer are analyzed. The design process of the central brake reducer is summarized. The reliability of the central brake reducer in Baja racing is proved by a lot of calculation and experimental results.
