Abstract

本实用新型涉及摩托车减震器力值调节杆耐压密封机构，连杆设有中心过油孔，调节杆位于中心过油孔内，在连杆和调节杆之间设有油封，油封设于连杆靠近接头一端端面，在连杆该端面上设有台阶，油封嵌于该台阶中。所述油封由油封体和油封骨架组成，油封骨架嵌于油封体内。油封体靠里侧端面设有环形槽，环形槽与油封中心孔之间的油封体形成抱合调节杆的油封唇口。本实用新型由于将油封设于连杆一端面，不但连杆端面的台阶容易加工和检验，而且也利于油封的装配。同时，油封唇口的设计相对传统的O型密封圈而言，更利于耐压和密封。

Description

摩托车减震器力值调节杆耐压密封机构
技术领域
本实用新型涉及摩托车减震器，具体指摩托车减震器力值调节杆耐压密封机构，本耐压密封机构装配简单，便于加工和检验。
背景技术
摩托车减震器挡位调节是通过改变连杆中心过油孔的大小来实现的，中心过油孔的大小是由调节杆来调节的。调节杆位于中心过油孔内，调节杆一端具有锥尖结构，中心过油孔内靠近液室一端设有定位管，锥尖***定位管内，锥尖进入定位管的深度不同，中心过油孔的大小就不同。由于中心过油孔内会进入减震油，故连杆和调节杆之间会设置密封装置。现有的密封机构是在连杆和调节杆之间设置O型密封圈，O型密封圈位于连杆内壁或者调节杆外壁的环形槽内，环形槽位于连杆或调节杆大约靠近中间位置，同时为了可靠地密封，这样的结构设有两个。现有的密封结构至少存在以下不足：1、环形槽由于不在连杆或调节杆端头，给加工带来了困难，也不利于O型密封圈的装配；2、普通的O型密封圈在耐压和密封效果上并非最佳；3、环形槽的加工状况和O型密封圈安装情况不方便检验。
实用新型内容
针对现有技术存在的上述不足，本实用新型的目的是提供一种便于加工和检验、装配简单、更利于耐压和密封的摩托车减震器力值调节杆耐压密封机构。
本实用新型的技术方案是这样实现的：摩托车减震器力值调节杆耐压密封机构，它包括连杆和调节杆，连杆设有中心过油孔，调节杆位于中心过油孔内，在连杆和调节杆之间设有油封，其特征在于：所述油封设于连杆靠近接头一端端面，在连杆该端面上设有台阶，油封嵌于该台阶中。
进一步地，所述油封由油封体和油封骨架组成，油封骨架嵌于油封体内。
所述油封体靠里侧端面设有环形槽，环形槽与油封中心孔之间的油封体形成抱合调节杆的油封唇口。
本实用新型由于将油封设于连杆一端面，不但连杆端面的台阶容易加工和检验，而且也利于油封的装配。同时，油封唇口的设计相对传统的O型密封圈而言，更利于耐压和密封。
附图说明
图1—本实用新型结构示意图；
图2—本实用新型油封结构示意图。
具体实施方式
下面结合附图和具体实施方式对本实用新型作进一步说明。
参见图1，从图上可以看出，本实用新型摩托车减震器力值调节杆耐压密封机构，它包括连杆1和带锥尖的调节杆2，连杆1设有中心过油孔，调节杆2位于中心过油孔内，在连杆1和调节杆2之间设有油封3，所述油封3设于连杆1靠近接头一端端面，在连杆1该端面上设有台阶4，油封3嵌于该台阶4中。
见图2，所述油封3由油封体5和油封骨架6组成，油封骨架6嵌于油封体5内。油封体5靠里侧端面设有环形槽7，环形槽7与油封中心孔9之间的油封体形成抱合调节杆的油封唇口8。
本实用新型由于将油封设于连杆一端面，不但连杆端面的台阶容易加工和检验，而且也利于油封的装配。同时，油封唇口的设计相对传统的O型密封圈而言，更利于耐压和密封。
