阅读说明：本技术 分离副缸的隔套、隔套组件以及分离副缸 (Spacer bush and spacer bush assembly of separation auxiliary cylinder and separation auxiliary cylinder ) 是由 瓦勒瑞·科特加罗 郑飞翔 于 2018-03-21 设计创作，主要内容包括：一种分离副缸的隔套(1),在它的基体(10)的外周面具有螺纹状凸起(12),该螺纹状凸起用于与壳体(2)的内周面的螺纹状凹部(20)接合。该隔套避免了或者大幅减少了在装配过程中产生碎屑的风险；隔套本身以及壳体的尺寸允许更大公差,因此对制造工艺要求更低；螺纹状凸起进一步增强了隔套和壳体在轴向上的定位,防止意外的脱离；且该隔套的应用范围很广,例如可以用于对中式分离副缸、外置式分离副缸。还提供了一种隔套组件以及分离副缸。(A spacer 1 for a release sub-cylinder has a screw-shaped protrusion 12 on the outer peripheral surface of a base 10 for engaging with a screw-shaped recess 20 on the inner peripheral surface of a housing 2. The spacer avoids or substantially reduces the risk of debris generation during assembly; the dimensions of the spacer itself and of the housing allow greater tolerances and therefore lower requirements on the manufacturing process; the threaded bulge further enhances the positioning of the spacer bush and the shell in the axial direction, and prevents accidental separation; the spacer bush has wide application range, and can be used for a middle-type separation auxiliary cylinder and an external-type separation auxiliary cylinder. A spacer assembly and a separate slave cylinder are also provided.)
