Method for widening application range of bellow type air spring

Abstract

The invention discloses a method for widening the application range of a bellow type air spring. The bellow type air spring comprises a base, an air chamber, a partition board, an air bag and a top plate, wherein the air chamber is defined by air chamber walls. The base is located at the bottom of the air chamber. The partition board is located at the top of the air chamber. A drainage hole is formed in the center of the partition board. The top plate is located above the partition board. The air bag is located between the partition board and the top plate and fixed to the partition board and the top plate through fixing elements, so that an expansion air chamber is formed by the air bag. An auxiliary bearing structure is welded to the portion, in the expansion air chamber, of the partition board to be used for protecting the air bag of the bellow type air spring, and the height of the auxiliary bearing structure is not larger than that of the air bag in a no-loaded state. The method for widening the application range of the bellow type air spring has the following advantages that (1) the bearing capacity of the bellow type air spring in a non-inflated state is improved; (2) the inflation rising speed of the bellow type air spring is guaranteed; (3) the height different of the bellow type air spring before inflation and after inflation is decreased; and (4) the service life of the air bag of the bellow type air spring is prolonged.

Description

technical field [0001] The invention belongs to the field of vibration isolation and noise reduction of air springs, and in particular relates to a method for increasing the use range of a capsule air spring. Background technique [0002] The air spring is a kind of high-efficiency shock absorber, which is widely used in vibration isolation projects. Generally, the spring is installed in place before the construction of the vibration isolation platform. During the construction of the platform, the air spring is in a no-pressure static load condition. In addition, the spring After being put into use, the idle working condition without air pressure will also carry the load of the platform and equipment, so that the spring airbag directly bears the pressure of the platform, which will greatly reduce the life of the spring. For spring vibration isolation equipment that is often charged and deflated, reducing the inflation lift height can increase the inflation speed of the sprin...
