Abstract: In response to the short comings of the leaf spring suspension, the four link suspension has evolved as the suspension of choice in recent years for large passenger vehicles that have solid drive axles. The geometric design of four link suspension allows for better control of roll centre location, anti-squat, antidrive performance and roll steer properties.The main purpose of Suspension system is to provide good ride comfort and provide good vehicle handling techniques. And the Suspension which best serves this purpose is Air-Suspensin system. This is because it provides good ride comfort in Variable load conditions. In this project a Bus having semi-elliptical leaf-spring type rear suspension is taken and is replaced by Air-Suspension to increase the Ride comfort, Vehicle braking and Handling Techniques. One type of four link type suspension called Sub frame type suspension is chosen. In this project, dimensions of the vehicle is taken manually and the design is created to fit air suspension.Then Analysis is done and then the customized model is sent for manufacturing. The Bus chosen is Bharat Benz 914 & 917. Both have similar rear suspension.
