Abstract
An improved vehicle suspension system for providing kneeling function to a vehicle having a modified lower floor. The suspension system includes a pair of springs each of which is respectively mounted at one of the rear wheels of the vehicle. The system also includes a pair of air suspension members, each is respectively mounted at one of the rear wheels for partially supporting the load of the vehicle. A compressor is used for supplying air to the suspension members. An exhaust valve provides a path for air to be exhausted from the suspension members to bring the vehicle lower to the kneeling height, and thereby provides the kneeling function.
