Optimization Analysis of the Efficiency of the Gear Box in the In-Wheel Drive System

In-wheel drive electric vehicles have the incomparable advantage over conventional electric vehicles, and the efficiency of the gear box is an important factor which affects the transmission efficiency of the electric vehicles. This paper focuses on a kind of gear boxes of the in-wheel drive system, in the premise of ensure the structure is stable and reliable, optimizes the related parameters with the goal of maximizing the efficiency of the gear box by using MATLAB optimizing toolbox. Comparing the optimization results with the efficiency before optimized,the influence of related parameters is studied. The results have practical significance to the selection of gear box parameters.
