Lightweight Design of Large and Small Chain Wheels of University Formula Racing Car Transmission System Based on CAD Technology

The achievements of the Chinese college students’ equation competition have already represented the strength of a college automobile field, and more and more auto related colleges and universities have paid more and more attention to this event. The vehicle drive system has a great influence on the power of the car, and the research of the light quantization in the power transmission system has become a hot spot of concern in the world. This paper will design and study the light weight of the large and small sprockets, and hope to draw lessons from the design of the other university students’ equation racing car.
