Description

一种共轨电磁阀
技术领域
本发明涉及的是一种汽车电磁阀的改进发明，特别涉及的是一种共轨电磁阀。
背景技术
共轨电磁喷油器通过ECM（Engine Control Module引擎控制模块）接收发动机各种传感器的信号，经过分析、计算、比较后向控制器发出脉冲指令，控制电磁阀线圈通电与断电时刻精确地实现燃油喷射。电磁阀能否快速响应控制器发出的脉冲指令，铁芯起到了很重要的作用。申请人于2014年向国家知识产权局申请了发明名称为《电磁阀的硅钢片卷制铁芯总成》的发明专利，专利号为201410230032.0，上述专利采用的铁芯采用片状硅钢片排列而成，具有电磁力高，电磁阀的可靠性强的优点，但是存在加工难度大、生产效率低，生产成本高的问题。
发明内容
鉴于背景技术存在的技术问题，本发明要解决的技术问题是提供一种加工简易、生产成本低，且电磁力高，使用稳定、可靠的共轨电磁阀。
为了解决上述技术问题，本发明是采用如下技术方案来实现的：该种共轨电磁阀，其特征在于包括有钢套、铁芯、磁粉芯、线圈及阀芯，所述铁芯和磁粉芯均为环形柱体，所述磁粉芯与铁芯贴合且同心设置，所述铁芯和磁粉芯套设在阀芯外，所述钢套套设在铁芯外，所述铁芯开设有一道缝隙，所述缝隙沿母线轴向设置，所述铁芯的表面开设有环形凹槽，所述线圈绕设在线圈架上，所述线圈架安装在环形凹槽内。
所述缝隙的宽度为8-10MM。
所述铁芯采用硅铁制成。
本发明的铁芯为整体式，加工简便，在铁芯上开设缝隙以使得涡流场不连续，如此减少高频涡流损耗，减少热量产生，增加电磁阀的可靠性，所述铁芯的缝隙宽度为8-10MM最佳，产生的热量最少；本发明还增加了磁粉芯，铁芯与磁粉芯结合增强通电时的电磁力。与现有技术相比，本发明不仅加工简易、生产效率高、生产成本低，而且电磁力大，电磁阀使用灵敏、稳定。
附图说明
图1为本发明的结构示意图。
图2为本发明铁芯的结构示意图。
具体实施方式
下面结合附图进一步描述本发明的工作原理及其有关细节，参照附图，该种共轨电磁阀，包括有钢套5、铁芯2、线圈3、阀芯及磁粉芯1，所述磁粉芯1和铁芯2均为环形柱体，即中空的的圆柱体，其横截面为环形，所述铁芯2采用硅铁压制而成，加工十分简便，加工速度快，成本低；所述磁粉芯1与铁芯2贴合且同心设置，所述磁粉芯1和铁芯2套设在阀芯外，所述钢套5套设在铁芯2和磁粉芯1外，所述铁芯2开设有一道缝隙6，所述缝隙6沿母线轴向设置，所述缝隙6以使得涡流场不连续，如此减少高频涡流损耗，减少热量产生，增加电磁阀的可靠性，所述缝隙的宽度为8-10MM最佳；所述铁芯2的表面开设有环形凹槽7，所述线圈3绕设在线圈架4上，所述线圈架4安装在环形凹槽7内，线圈通电后，线圈3与铁芯2、磁粉芯1产生相应的电磁力并发生电磁感应，使阀芯的阀杆轴向移动，实现电磁阀精确喷射燃油。
本发明与现有技术相比，加工简便，生产效率高、生产成本低，而且开有缝隙的铁芯结合磁粉芯，不仅电磁力强，而且产生的热量少，电磁阀启动、关闭稳定，速度快，实现燃油的精确喷射。
