Suspension systems must support both road holding/handling and ride quality, which are at odds with each other. (�� Figure 9: Rubber axlebox suspension system. (�� (�� <> 5 0 obj (�� <> stream Passenger cars commonly use front suspension as Macpherson suspension system to absorb road shocks and provide comfort to passengers. 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.
