a Four Wheel Drive System for a Formula Style Electric Racecar

Abstract

This is a master thesis detailing the development and design of a four wheel drive transmission system for a formula style race car using four electric motors to achieve asynchronous power output to each wheel. First an in depth analysis was performed in order to identify key system performance parameters. A concept development phase was used to come up with a system layout based on the performance requirements. The transmission system was then designed and calculated using KISSSoft. Topology optimization in OptiStruct was used to design the gearbox/wheel upright. Results have been evaluated, showing significant reduction in weight and increase in performance over existing systems. Manufacturing documentation has been designed for every part of the system. A discussion on commercial viability of such a system has then been discussed.
