Square high-load air spring

Abstract

The invention discloses a square high-load air spring. The square high-load air spring comprises a sac body, an upper snap ring, a lower snap ring, an upper cover plate, a lower cover plate, an upper limiting part, a lower limiting part and a plurality of connecting pieces, wherein the sac body is formed by vulcanizing a sac body rubber, a framework layer, an upper seam allowance steel ring and a lower seam allowance steel ring together; the upper cover plate and the lower cover plate are provided with grooves which are matched with the shapes of the upper seam allowance steel ring and the lower seam allowance steel ring of the sac body; the sac body is assembled on the upper and lower cover plates through the grooves; the upper seam allowance steel ring of the sac body is tightly pressed on the upper cover plate by the upper snap ring, and the lower seam allowance steel ring of the sac body is tightly pressed on the lower cover plate by the lower snap ring; the upper and lower snap rings are connected and fastened to the upper and lower cover plates through the connecting pieces; the upper and lower limiting parts are positioned in the sac body, the upper limiting part is connected to the upper cover plate through the connecting pieces, and the lower limiting part is connected to the lower cover plate through the connecting pieces; and an air hole and mounting holes are formed on the upper cover plate.

Description

technical field [0001] The invention relates to a mechanical component device, in particular to a square high-load air spring for ships. Background technique [0002] Vibration and noise are ubiquitous in nature and life, and have brought many problems to people. In order to improve the safety of equipment and the comfort of human life, many vibration and noise reduction components are applied. Commonly used vibration damping components include rubber vibration isolators, metal vibration isolators, and pneumatic vibration dampers. Air spring is an important vibration and noise reduction product. Due to its low natural frequency, nonlinear stiffness and many other advantages, it is widely used in automobiles, railway vehicles, ships, aviation and various mechanical equipment. [0003] At present, air springs at home and abroad can be roughly divided into two types: capsule type and membrane type, and the airbags are mostly circular. For some applications, such as ships, du...
