ABSTRACT:
In a switchable suspension system for automobiles and other vehicles, an auxiliary air-spring chamber is provided above a main air-spring chamber in such a manner as to enclose a piston rod so that the spring force of the suspension can be adjusted appropriately. An air passage to connect the two air-spring chambers is provided in the piston rod. The piston rod and a control rod extending inside the piston rod make up a switch valve that controls the opening and closing of the air passage. The air passage of the suspension system is enclosed with a cover to cut off the outward leakage of the noise resulting from the inflow and outflow of air through the air passage that leads from an air compressor to the two air-spring chambers of the suspension system.
