  • Abstract:
  • Suspension is the system that connects a vehicle (chassis) to its wheels and allows relative motion between the two with the help of suspension linkages, shock absorbers and wheel uprights. Suspension system is responsible for the handling, road holding and ride quality of the vehicle. It is important for the suspension system to keep the road and wheels in contact. In automobile suspension a suspension link or control link is a suspension member, that connects at two points, one point on the frame and other attached to the upright. A link provides pivot and can control only one degree of freedom by itself. Independent suspension system allows each wheel on the same axis to move vertically independently of the other wheel. Independent suspension in off-road typically offers better ride quality and handling characteristics, due to lower un- sprung weight and the ability of each wheel to address the road undisturbed by activities of the other wheel on the vehicle. The available options for independent suspension systems for an All-Terrain Vehicle are mainly: Macpherson Strut, Trailing Arm/Semi-Trailing Arm, Double A-arm Suspension, Multi-link Suspension, H-arm and Camber link. Two link independent suspension system having an H-arm and a camber link is chosen for the application for its simplicity in design and application. An innovative solution to reduce the weight of suspension system by eliminating the camber link and using driveshaft with double Hooke joint as a suspension link which governs the wheel camber throughout the suspension travel. The driveshaft is also responsible for transmitting torque and rotation from the differential to the wheel hub. Double Hooke joint is used to provide sufficient articulation angle to accommodate vertical wheel travel and also acts like a suspension link as it provides only one degree of freedom. The primary aim is to reduce weight as it improves the overall performance of the vehicle i.e. reduction in un-sprung mass, better acceleration, enhanced handling and reduce the overall production cost by eliminating an entire link.
