Job title



In this era of electrification, HEVs are mainly focused on weight and space saving. This is done to ensure the maximum size of the battery package on the vehicle. This situation demands for a drive by wire systems which makes the vehicle lighter as well as more spacious. This paper introduces a new type of In-Wheel suspension has been introduced in this paper. The problem of large suspension systems and its bulkiness were studied. Vehicle instability while driving and cornering was also stated. And the suspension's capability to handle uneven tyre wear which is caused due to improper or fixed camber angle was also addressed.

The Novel In-Wheel Suspension is introduced in this paper which houses all the crucial parts of the suspension inside the rim of the wheel thus making it compact, lighter and sturdy. Parts were first designed by the principles of Machine Design, Kinematics and Mechanics of Materials. They were later modelled on Solid Edge ST7. Structural simulations was carried out on FEA Solver under highly strained conditions and also under dynamic loading and the results were satisfactory.

A scaled prototype was made by manufacturing the parts on CNC machine. Later the suspension was assembled by brazing the parts together. The Impulse hammer technique was used to carry out the modal analysis which was used to study the damping characteristics of the suspension. Another innovation is introduced in this suspension which the Novel concept of Automatic Camber Control strategy which calibrates the camber angle of the wheel in real-time and greatly improves the performance as well as stability of the vehicle. The design process involved understanding the scaling down the size of the suspension without compensating the functionality of the suspension. The working prototype of the suspension was constructed and after rigorous testing which were carried out. It was found that the performance of suspension under low traction conditions was enhanced.
