Abstract
A combined air spring system includes an upper cover plate, an air bag, an upper end plate and a lower end plate. An outer periphery of the upper cover plate is connected with an outer periphery of the upper end plate through the air bag. A low-position sand clock elastomer is connected between the upper end plate and the lower end plate. A pressing plate is installed at a bottom portion of the upper cover plate, and a high-position elastomer is connected between the upper cover plate and the pressing plate. A limiting table is arranged at a bottom portion of the pressing plate. A limiting groove is formed in a top face of the upper end plate. The limiting table is located in the limiting groove in a deflated state.
