Design and Development of Coil Over Spring Suspension for Differential Drive Electric 3-Wheelers

Abstract

The three-wheeler vehicle segment is crucial for urban mobility and last-mile connectivity in many developing nations. It needs chassis designs that are lightweight, cost-effective, robust, and safe. This paper reviews recent structural design, material selection, and computational analysis techniques for three-wheeler chassis. It synthesizes literature on Computer-Aided Design (CAD) methodologies, advanced materials, Finite Element Analysis (FEA), and optimization under different loads. The aim is to consolidate knowledge, identify research gaps, and suggest future directions for safer, more efficient three-wheeler chassis.
