Abstract

本实用新型是一种柔性柱塞,由柱塞架、中空式塑料套构成,其特征是,带油孔的柱塞架外,底部设有一圈凹槽,柱塞架外,注有中空式塑料套,中空式塑料套下部直径与上部直径不同,即,上大下小,中空式塑料套内,设有一圈与柱塞架外底部凹槽相对应的凸楞。该柔性柱塞,具有设计合理、结构简单、造价低、中空式塑料套无缺口、伸缩性强、抗磨损,使用过程中能弥补磨损所产生的间隙,使用周期长等特点。

Description

一种柔性柱塞
技术领域:本实用新型涉及轿车减震器,具体地说是减震器中的一种柔性柱塞。
背景技术:目前,轿车减震器控制油的流向靠底阀和柱塞,密封靠各个部件的间隙。减震器使用一段时间后,柱塞和减震器内筒的间隙由于磨损就会逐渐变大,以至拉力下降,减震效果降低,如间隙过大就会失去减震作用。
发明内容:本实用新型的目的在于,研制出一种结构科学、耐磨、使用周期长、减震效果好、减震器内筒内壁磨损后能弥补间隙的柔性柱塞。其主要技术内容是,一种柔性柱塞,由柱塞架、中空式塑料套构成,其特征是,带油孔的柱塞架外,底部设有一圈凹槽,柱塞架外,注有中空式塑料套,中空式塑料套下部直径与上部直径不同,即,上大下小,中空式塑料套内,设有一圈与柱塞架外底部凹槽相对应的凸楞。本实用新型和现有技术相比所具有先进之处在于,一种柔性柱塞,具有设计合理、减震效果强、抗磨损、使用过程中能补尝减震器内筒内壁磨损所产生的间隙等特点,从而克服了现有减震器内柱塞使用周期短、拉力下降、减震效果差等不足之处。
附图说明:
图1为本实用新型俯视图;
图2为本实用新型正剖结构示意图
其中,油孔1、柱塞架2、中空式塑料套3、凹槽4、凸楞5。
具体实施方式:下面结合附图1-2对本实用新型再作进一步地描述,带油孔1的柱塞架2外,底部设有一圈凹槽4,柱塞架2外,注有中空式塑料套3,中空式塑料套3下部直径与上部直径不同,即,上大下小,中空式塑料套3内,设有一圈与柱塞架2外底部凹槽4相对应的凸楞5,以上便构成实用新型。
