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.

Combined air spring system

An emergency air spring assembly includes an upper cover plate, an air bag, an upper end plate and a lower end plate. An outer periphery of the upper end plate is connected with an outer periphery of the lower end plate through the air bag. An hourglass elastomer is connected between the upper cover plate and the upper end plate. A plurality of steel springs are arranged between the upper cover plate and the upper end plate in a circumferential direction of the sand clock elastomer in a pressing mode.

Emergency air spring assembly

A prepressed emergency air spring assembly includes an upper cover plate, an air bag, an upper end plate and a lower end plate. The periphery of the upper end plate is connected with an outer periphery of the lower end plate through the air bag. A steel spring is arranged between the upper cover plate and the upper end plate in a pressing mode. A plurality of hourglass elastomers are arranged between the upper cover plate and the upper end plate along a circumferential direction of the steel spring.

Prepressed emergency air spring assembly

A pre-compression type emergency air spring assembly includes an upper cover plate, an air bag, an upper end plate, and a lower end plate. A periphery of the upper end plate is connected with a periphery of the lower end plate through the air bag. A top part of the upper end plate is provided with transverse pre-compression cavities and transverse pre-compression plates arranged at transverse openings of the transverse pre-compression cavities. The transverse pre-compression cavities are internally provided with laminated spring elastomers through the transverse pre-compression plates in a pressing mode. Multiple steel springs are arranged between the upper cover plate and the upper end plate in a pressing mode along a circumferential direction of the laminated spring elastomers. The upper cover plate is arranged on a periphery of the transverse pre-compression cavities in a sleeving mode.
