    • An air spring assembly has a pair of spaced end plates (5, 6) and a flexible sleeve (12) extending therebetween forming an internal fluid chamber. One of the end plates is a bead plate which is crimped ti an open end of the sleeve. An insert having an internally threaded hole is mounted in a central hole formed in the bead plate. An externally threaded coupler (30) having a hollow bore (32) is mounted in a central opening (19) formed in an end member of an auxiliary reservoir (3) and is threadably engaged with the internally threaded hole (23) to mount the auxiliary reservoir (3) in an abutting relationship on the air spring bead plate to provide a variable rate air spring. A fluid path is provided through the threaded connection for the flow of fluid between the air spring and auxiliary reservoir.
    • 空气弹簧组件具有一对间隔开的端板(5,6)和在其间延伸的柔性套筒(12),形成内部流体室。 端板中的一个是在套筒的开口端处卷曲的胎圈板。 具有内螺纹孔的插入件安装在形成在胎圈板中的中心孔中。 具有中空孔(32)的外螺纹联接器(30)安装在形成在辅助容器(3)的端部构件中的中心开口(19)中,并且与内螺纹孔(23)螺纹接合以安装 辅助贮存器(3)在空气弹簧胎圈板上具有邻接关系,以提供可变速率的空气弹簧。 通过用于空气弹簧和辅助容器之间的流体流动的螺纹连接件提供流体路径。
