Abstract
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.
