Design of Suspension System and its effect on different Sub-Systems in an ATV

ABSTRACT Suspension system is one of the important Subsystems in an ATV. It ensures both safety and comfort of the driver. The main aim of this paper is to design the suspension system of an ATV and explain the suspension parameters that have a significant impact on other subsystems such as the frame, braking, and steering. The study of relations between sub-systems is important because the effective functioning of the vehicle is dependent on the coordination between the two sub-systems. The design of suspension includes design methodology, design considerations, and design parameters of different components like the knuckle, hubs, control arms, and the result of iterations. Catia V5 and Solid Works are used to build the CAD model and Auto CAD is used for 2D projections furthermore Lotus Shark to acquire hard points of the suspension system. Keywords: Suspension, Camber, Knuckle, castor, Control arms, Steering.
