Problems solved by technology

At present, the commonly used auxiliary springs are mostly rubber springs, mainly including hourglass springs, conical springs and layered springs. Among the three kinds of springs, the vertical stiffness of the conical spring is relatively small when the load is large, and some vehicles have a large load when the empty spring has no air. When the auxiliary spring is required to provide very small vertical stiffness, the general rubber spring cannot achieve it.

Abstract

The invention discloses a combined air spring assembly which comprises an upper cover plate, an airbag, a base, an outer metal sleeve, an inner metal press sleeve, a rubber spring set and a steel spring set. The outer metal sleeve is mounted on the base. The inner metal press sleeve is mounted in the outer metal sleeve in a sleeved manner and can move downwards along the inner ring wall of the outer metal sleeve. The rubber spring set is mounted in the inner metal press sleeve in a sleeved manner. The steel spring set is mounted in the rubber spring set in a sleeved manner. The inner metal press sleeve is pressed at the top of the rubber spring set and the top of the steel spring set. The periphery of the upper cover plate is connected with the periphery of the outer metal sleeve through the airbag. An air spring system has the advantages of being simple and compact in structure, low in air leaking heavy load vertical rigidity and high in comfort and stability.

Description

technical field [0001] The invention mainly relates to buffering and damping technology, in particular to a combined air spring assembly. Background technique [0002] Now the air spring needs to bear more and more vehicle loads. The airbag adopts a large curved airbag, which can reduce the stiffness value of the air spring system when it is inflated by increasing the space of the auxiliary air chamber. However, when there is no air, the auxiliary spring is required to provide vertical stiffness to ensure the normal operation of the vehicle. However, some vehicles are very unloaded. Under the premise of ensuring the stiffness of the inflation system, the auxiliary spring is required to provide a small vertical stiffness when the large load is deflated. At present, the commonly used auxiliary springs are mostly rubber springs, mainly including hourglass springs, conical springs and layered springs. Among the three kinds of springs, the vertical stiffness of the conical sprin...
