AI Technical Summary
Technical Problem
Under extreme conditions, the airbags in the composite air suspension are prone to detaching during vehicle operation, resulting in significant vehicle bouncing.
Method used
A suspension rope is installed between the vehicle frame longitudinal beam and the airbag suspension. The suspension rope applies a restoring force to the airbag suspension, limiting its floating and preventing it from being pulled off.
Benefits of technology
It effectively controls the airbag's release under extreme conditions, reducing vehicle bouncing during driving and improving vehicle stability and comfort.

Abstract
This application relates to an airbag limiting device for a composite air suspension, comprising: a frame assembly, a rear axle assembly, and a limiting mechanism. The frame assembly includes parallel and spaced longitudinal beams. The rear axle assembly includes a rear axle and an airbag suspension connecting the rear axle and the longitudinal beams. The limiting mechanism includes a suspension rope connecting the longitudinal beams and the airbag suspension. By providing the suspension rope between the longitudinal beams and the airbag suspension, the airbag suspension can be limited in an extreme state, controlling airbag deployment and solving the technical problem in related technologies where, in an extreme state, the vehicle bounces significantly during driving, causing airbag deployment.
