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 system. The combined air spring system comprises an upper cover plate, an air bag, a base, an outer metal sleeve, an inner metal pressing sleeve, a rubberspring set and a steel spring. The outer metal sleeve is arranged on the base, the inner metal pressing sleeve is sleeved with the outer metal sleeve, a gap is formed between the inner metal pressingsleeve and the inner wall of the outer metal sleeve, and the rubber spring set is arranged in the gap. The steel ring is arranged in the inner metal pressing sleeve, the inner metal pressing sleeve is pressed on the tops of the rubber spring set and the steel spring, and the periphery of the upper cover plate is connected with the periphery of the outer metal sleeve through the air bag. The air spring system has the beneficial effects that the structure is simple and compact, the air release heavy load vertical rigidity is low, and comfort and stability are high.

Description

technical field [0001] The invention mainly relates to buffering and damping technology, in particular to a combined air spring system. 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 spring ...
