Suspension system also provide the vehicle stability in running condition. (�� (�� (�� 8.7 FUNCTIONS OF SUSPENSION SYSTEM (a) The main function of a suspension system is to prevent the socks to transmit to car or vehicle body so that passengers may ride comfortably. (�� 5 Suspension System Terms • Camber: Looking directly at the front of the vehicle, camber refers to the tilt in (+) or out (‐) of the bottom half of the tire. 2 0 obj Instead of a classic springing and damping system using coil springs and gas-pressure shock absorbers, this featured the newly developed, electronically controlled AIRMATIC system, in which the air suspension and the adaptive damping system (ADS) form an integral unit, including individual, automatic level control on each wheel. It is relatively easy to implement a self-levelling air suspension system.

(�� (�� (�� (�� (�� Added to the mix is the fact that air suspension kits only replace coil springs, and coil springs are part of a larger suspension system. (�� <> (�� The state-space and transfer function models of the bus suspension problem were derived in the Suspension: System Modeling page. This problem is not easy because it is a multi-objective problem and has too many design variables. (�� • Suspension systems follow the road surface in order to maintain traction, control vehicle, and provide passengers smooth ride.
