Pre-compaction type air spring system

Abstract

The invention discloses a pre-compaction type air spring system. The pre-compaction type air spring system comprises an upper cover plate, a gasbag, an upper end plate and a lower end plate, wherein the periphery of the upper cover plate is connected with the periphery of the upper end plate through the gasbag; a lower elastomer is connected between the upper end plate and the lower end plate; a pre-compaction plate is arranged on the top of the upper end plate; a higher ring-shaped elastomer is arranged between the pre-compaction plate and the upper end plate; and a first stop part which is positioned in the higher ring-shaped elastomer is arranged on the middle position of the pre-compaction plate. The air spring system has the advantages of being simple in structure, convenient to mount, low in gas-leakage heavy-load perpendicular rigidity and high in comfort and stability.

Description

technical field [0001] The invention mainly relates to buffering and damping technology, in particular to a preloaded air spring system. Background technique [0002] When the vertical load is not large, the air spring has a combination form of a belt-type airbag and a conical spring or an hourglass spring. When applied to larger loads, the combination of belt-type airbags and laminar springs is generally used, but the vertical stiffness of the laminar springs is generally large, resulting in an increase in the derailment coefficient of the laminar springs when they work alone in the deflated state. Forced to reduce operating speed. Therefore, it is necessary to design a new structural form. Under the premise of ensuring the stability of the air spring in the inflated and deflated state under large loads, the vertical stiffness in the deflated state is reduced to improve the safety and comfort of the deflated operation and ensure the deflated state. The lower speed will no...

When applied to larger loads, the combination of belt-type airbags and laminar springs is generally used, but the vertical stiffness of the laminar springs is generally large, resulting in an increase in the derailment coefficient of the laminar springs when they work alone in the deflated state. Forced to slow down

Therefore, it is necessary to design a new structural form. Under the premise of ensuring the stability of the air spring in the inflated and deflated state under large loads, the vertical stiffness in the deflated state is reduced to improve the safety and comfort of the deflated operation and ensure the deflated state. The lower speed will not reduce too much to affect the efficiency
