摘要： The present invention discloses an air spring design wherein the second retainer plate utilized in some conventional designs is eliminated. This accomplishes the objective of reducing the manufacturing cost of the air spring as well as its weight. The air springs of this invention also offer an advantage over conventional air springs that do not include a second retainer plate in that the flexible member of the air spring cannot be detached from the piston. The subject invention more specifically discloses an air spring which is comprised of a retainer plate, a piston, and an elastomeric sleeve, wherein the elastomeric sleeve is sealingly engaged with the first retainer plate and the piston to define a pressurizable chamber, wherein the piston has a wall which provide a surface on which the elastomeric sleeve rolls during compression, wherein the piston has a bead seal which extends from the piston wall toward the center of the air spring to provide a surface onto which the elastomeric sleeve is crimped with a crimp ring which extends from the bead seal.

摘要翻译： 本发明公开了一种空气弹簧设计，其中消除了在一些常规设计中使用的第二保持板。 这实现了降低空气弹簧制造成本及其重量的目标。 与不包括第二保持板的传统空气弹簧相比，本发明的空气弹簧的优点在于，空气弹簧的柔性部件不能从活塞拆卸下来。 本发明更具体地公开了一种空气弹簧，该空气弹簧包括保持板，活塞和弹性套筒，其中弹性套筒与第一保持板和活塞密封接合以限定可加压腔室，其中活塞具有 提供弹性套筒在压缩期间滚动的表面的壁，其中活塞具有从活塞壁朝向空气弹簧的中心延伸的凸缘密封件，以提供表面，弹性套筒用压接环 其从珠密封件延伸。
