Abstract

本实用新型公开了一种制动主缸,包括有缸体,缸体的内腔中滑动安装有活塞,活塞的两端分别套装有皮碗、副皮圈,副皮圈的后侧设有挡圈,缸体的前端安装有闷盖,闷盖内安装有残留阀,缸体的侧壁上安装有放气螺钉,放气螺钉端部安装有放气帽。本实用新型采用皮碗、副皮圈双层密封,由于采用上述结构特征,从而实现了一人操作即可排除制动轮缸内气体的目的,同时本实用新型结构简单,基本不增加原有制动轮缸的成本。

Description

一种制动主缸
技术领域
本实用新型涉及汽车制动领域,具体属于一种制动主缸。 
背景技术
一种制动主缸是由制动缸盖、活塞、活塞杆、皮碗及缓解弹簧等组成,通过三通阀的作用,使压缩空气进入制动缸时,推动活塞通过一套基础装置而起制动作用。目前的一种制动主缸的结构设计不够合理,体积笨重,制动效果差。 
实用新型内容
本实用新型的目的是提供一种制动主缸,结构设计合理,采用皮碗、副皮圈双层密封,由于采用上述结构特征,从而实现了一人操作即可排除制动轮缸内气体的目的,同时本实用新型结构简单,基本不增加原有制动轮缸的成本。 
本实用新型的技术方案如下: 
一种制动主缸,包括有缸体,缸体的内腔中滑动安装有活塞,活塞的前端为弹簧,活塞的两端分别套装有皮碗、副皮圈,副皮圈的后侧设有挡圈,缸体的前端安装有闷盖,闷盖内安装有残留阀,缸体的侧壁上安装有放气螺钉,放气螺钉端部安装有放气帽。 
所述的闷盖与缸体的端部之间垫置有垫片。 
本实用新型的进气孔通入压缩气体,并推动活塞滑动,通过防尘盖的弹力从而控制推动活塞的推动力大小,结构设计合理,采用皮碗、副皮圈双层密封,由于采用上述结构特征,从而实现了一人操作即可排除制动轮缸内气体的目的,同时本实用新型结构简单,基本不增加原有制动轮缸的成本。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
参见附图,一种制动主缸,包括有缸体1,缸体1的内腔中滑动安装有活塞2,活塞的前端为弹簧11,活塞2的两端分别套装有皮碗3、副皮圈4,副皮圈的后侧设有挡圈5,缸体的前端安装有闷盖6,闷盖6内安装有残留阀7,缸体的侧壁上安装有放气螺钉8,放气螺钉8端部安装有放气帽9,闷盖与缸体的端部之间垫置有垫片。 

Claims (2)
