Air spring characteristics:
(1) with nonlinear characteristics, and its characteristic curve can be designed to be ideal shape;
(2) the quality of light, in the small, the high frequency vibration has a good ability of noise elimination of vibration isolation;
(3) stiffness and bearing capacity by adjusting the rubber gasbag internal pressure to adjust;
(4) manufacturing process is complex, high cost. When air spring according to the working mode of deformation is divided into capsule, membrane type and hybrid three.
