    摘要： A unitized seal for use in a gas spring seal assembly. The unitized seal includes a rigid thermoplastic insert having an elastomeric sealing layer surrounding the insert and bonded to the insert. The insert provides rigidity to the seal and includes a central, axial opening that receives and guides a rod slidably engaged with the insert. The sealing layer engages the interior surface of the gas spring cylinder to prevent the pressurized gas contained within the gas spring from escaping around the seal. The sealing layer also includes a central, axial opening aligned with the passage in the insert that slidably engages the rod and further prevent gas from escaping the gas spring cylinder. The unitized seal may be formed in a single or two-step process. In the single step process, the insert and sealing layer are formed by injection molding processes in a single mold and are bonded to one another by a subsequent covulcanization process. In the two-step process, the insert is formed in a first injection molding step, and has an adhesion promoter applied to the exterior of the insert. The coated insert is then placed within a second mold that is used to form the sealing layer about the insert in a subsequent injection molding process. The adhesion promoter intimately bonds the sealing layer to the insert forming the unitized seal.

    摘要翻译： 用于气体弹簧密封组件的单元密封件。 组合式密封件包括刚性热塑性塑料插入件，其具有围绕插入件并结合到插入件上的弹性体密封层。 插入件为密封件提供刚性并且包括中心的轴向开口，其接收并引导与插入件可滑动地接合的杆。 密封层接合气弹簧缸的内表面，以防止包含在气弹簧内的加压气体绕密封件逸出。 密封层还包括与插入件中的通道对准的中心轴向开口，其可滑动地接合杆，并且进一步防止气体逸出气体弹簧缸。 组合式密封件可以以一个或两个步骤的方式形成。 在单步骤中，插入和密封层通过在单个模具中的注射成型工艺形成，并且通过随后的共硫化工艺彼此粘结。 在两步法中，插入物在第一注塑步骤中形成，并且具有施加到插入件外部的粘合促进剂。 然后将涂覆的插入件放置在第二模具中，该第二模具用于在随后的注射成型工艺中围绕插入件形成密封层。 粘合促进剂将密封层紧密地粘合到形成组合密封件的插入件上。

    摘要： A method of forming a stabilizer bar is provided that includes the steps of roll forming sheet metal coil into a continuous tube. Next, a first portion of the continuous tube is flattened. The first portion of the continuous tube is sheared to define a first end. Next, a second portion of the continuous tube is flattened. The continuous tube is sheared at the second portion to define a final unit length with a second end opposite the first end. That is, the length is sheared from the rest of the continuous tube. The final length is the length is needed to form a single stabilizer bar. Finally, the final unit length is deformed into the desired stabilizer bar shape.
