The invention belongs to the technical field of air spring, in particular to a restrained rubber airbag. The new restrained rubber airbag comprises an upper cylindrical and a lower conical composite structure, which is vulcanized into an integral whole by inner and outer rubber and cord. The cylindrical structure of the airbag body is internally provided with a supporting ring, and the outer part of the airbag body is provided with a supporting ring. The outer restraint cylinder, the air bag body and the support ring are connected by pressure buckling; the outer restraint cylinder is designed by upper and lower arc flanging, and has a straight cylinder structure. The screw anti-skid line is arranged at the corresponding buckling position on the inner wall of the outer restraint cylinder. The new rubber balloon is protected by external restraint cylinder and has stable inflation diameter and mechanical characteristics. It can effectively avoid friction interference with peripheral components, reduce the influence of external mud and sand, and improve the fatigue life and safety of products.

一种约束型橡胶气囊
本专利技术属于空气弹簧
,具体涉及一种约束型橡胶气囊。
技术介绍
空气弹簧是一种较为理想的弹性元件,采用空气作为工作介质,具有理想的非线性力学特性,广泛应用于商用车驾驶室、车辆悬架、设备减震等领域,采用空气弹簧的车辆具有良好的乘坐舒适性和道路友好性等。橡胶气囊是空气弹簧的关键部件,橡胶气囊的性能决定了空气弹簧的性能。但现有技术中,空气弹簧结构中橡胶气囊为无约束设计,橡胶气囊在工作过程中,气囊外径变化大,特别是受到振动冲击较大工况和橡胶气囊经过反复疲劳后,橡胶气囊的外径变大容易导致气囊表面与周边部件产生干涉摩擦,使橡胶气囊过早失效,降低空气弹簧的疲劳寿命和安全性。
