Abstract
In an air suspension device of a vehicle having a parallel combination of an air spring and a shock absorber, a housing to provide the air spring has an upper half cylindrical portion of a smaller diameter and a lower half cylindrical portion of a larger diameter; the shock absorber is coaxially disposed in the housing such that its upper axial end is connected with an upper end of the housing via a first elastic cushion while its lower axial end is axially extended out of the lower end of the housing to be connected with a wheel suspension member of the vehicle; an annular flange is coaxially mounted to the lower axial end of the shock absorber; an annular rolling diaphragm is extended between the open lower end of the housing and the annular flange so as to define a closed air chamber with the housing means; and a second elastic cushion is attached to the upper end of the housing for connection with a body of the vehicle.
