Description

端部供油的机油控制阀及其组装方法
本申请要求2014年8月27日提交中国专利局、申请号为201410429431.X、发明名称为“端部供油的机油控制阀及其组装方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明属于可变气门正时(Variable Valve Timing，简称VVT)技术领域，特别是涉及一种端部供油的机油控制阀(Oil Control Valve，简称OCV)及其组装方法。
背景技术
机油控制阀是可变气门正时系统的核心部件之一。现有机油控制阀按供油方式分为端部供油的机油控制阀和侧面供油的机油控制阀两种。
结合图1至图2所示，现有一种端部供油的机油控制阀包括比例电磁铁1和液压体2两个部分。其中，比例电磁铁1包含可动电枢10。液压体2包含：阀体20，一端与比例电磁铁1固定连接、另一端设有进油口I；过滤器21，具有环形主体部21a、以及固设于环形主体部21a内周面上的滤网21b，环形主体部21a固设于阀体20设有进油口I的一端的外周面，滤网21b位于进油口I的外侧，液压油经过滤器21过滤后，自进油口I流向阀体20内；位于阀体20内的由内向外(即自比例电磁铁1至进油口I的方向A)依次排列的推杆22、可移动的活塞23、压缩弹簧24、弹簧座25、卡簧26。
其中，推杆22沿轴向的两端分别与可动电枢10、活塞23固定连接；压缩弹簧24的两端分别抵靠活塞23远离推杆22的端部、弹簧座25，并呈压缩状态；卡簧26固定在阀体20的内周面上，并沿轴向抵靠弹簧座25。
但是，现有端部供油的机油控制阀存在以下不足：1)过滤器21、弹簧座25、卡簧26是彼此独立的部件，不仅造成机油控制阀的结构 较为复杂、成本增加，而且，在组装时需先后逐个安装弹簧座25、卡簧26、过滤器21，造成组装工序较为繁琐、组装周期较长。
2)过滤器21中环形主体部21a的材料为钢，环形主体部21a与阀体20过盈配合，需利用拆卸工具撬起环形主体部21a后，才能将过滤器21从阀体20上拆卸下来，该拆卸过程会对过滤器21造成破坏，造成过滤器21无法重复使用。
3)弹簧座25利用冲压工艺形成，但是，冲压工艺很难保证加工精度，为了制作出加工精度高的弹簧座25，对冲压工艺的要求较为严格，会增加弹簧座25的加工成本。
发明内容
本发明要解决的问题是：现有端部供油的机油控制阀的结构较为复杂，不仅造成成本较高，还造成组装工序较为繁琐、组装周期较长。
为解决上述问题，本发明提供了一种端部供油的机油控制阀，包括：阀体，具有位于轴向一端的进油口；位于所述阀体内的呈压缩状态的压缩弹簧；过滤器，用于过滤自所述进油口流向所述阀体内的液压油，所述过滤器包括：环形主体部、以及固设于所述环形主体部上的滤网；所述过滤器位于所述阀体内，所述压缩弹簧位于所述过滤器远离进油口一侧且抵靠所述环形主体部的端面；所述阀体内周面设有卡槽；所述过滤器还包括：凸起，突出于所述环形主体部的外周面且沿径向向外突伸入所述卡槽内。

可选的，所述凸起具有面向所述阀体内周面的斜坡面以便于过滤器自进油口安装至所述阀体内部。
可选的，所述阀体在所述进油口处设有内倒角。
可选的，还包括：比例电磁铁，与所述阀体轴向的另一端固定连接，所述比例电磁铁包括可动电枢；位于所述阀体内的推杆和活塞，所述推杆的一端与所述可动电枢固定连接、另一端与活塞固定连接，所述压缩弹簧被压缩在所述活塞和所述过滤器之间。
另外，本发明还提供了一种机油控制阀的组装方法，包括：提供一阀体，所述阀体具有位于轴向一端的进油口、以及位于内周面的卡槽；提供一压缩弹簧；提供一过滤器，所述过滤器用于过滤自所述进油口流向所述阀体内的液压油，并包括：环形主体部、固设于所述环形主体部上的滤网、以及突出于所述环形主体部外周面的凸起；首先，将所述压缩弹簧自进油口安装至阀体内；接着，将所述过滤器自所述进油口塞入阀体内，所述凸起沿径向向外突伸入所述卡槽内，且所述环形主体部远离进油口的端面抵靠压缩弹簧，使所述压缩弹簧呈压缩状态。

具体实施方式
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
第一实施例
结合图3至图4所示，本实施例的机油控制阀包括：比例电磁铁A和液压体B两个部分。其中，比例电磁铁A包含可动电枢1。液压体B包含：阀体2，阀体2具有位于轴向一端的进油口I、以及位于阀体2内周面的卡槽20，卡槽20与进油口I沿轴向存在间隔，阀体2轴向的另一端与比例电磁铁A固定连接；位于阀体2内的由内向外(即自比例电磁铁A至进油口I的方向)依次排列的推杆3、活塞4、压缩弹簧5、过滤器6。
其中，推杆3的一端与可动电枢1固定连接、另一端与活塞4固定连接；压缩弹簧5被压缩在活塞4和过滤器6之间。过滤器6位于压缩弹簧5靠近进油口I的一侧，用于过滤自进油口I流向阀体2内的液压油。过滤器6与阀体2几乎无缝隙贴合，使得液压油不会未经过滤就从过滤器6与阀体2之间的间隙流向阀体2内。
如图4所示，过滤器6包括：环形主体部60，环形主体部60面向压缩弹簧5的端面设有环形第一凹槽610，压缩弹簧5的一端伸入第一凹槽610内，并抵靠第一凹槽610的底壁611；滤网61，固设于环形主体部60的内周面；凸起62，突出于环形主体部60的外周面S1且沿径向向外突伸入卡槽20内。由于压缩弹簧5被压缩在活塞4和过滤器6之间，因此，压缩弹簧5会向环形主体部60施加指向环形主体部60的轴向作用力。环形主体部60能够将所述轴向作用力传递给凸起62，使得凸起62沿阀体2轴向抵靠卡槽20的槽壁，进而 使得过滤器6固定在阀体2内。
在具体实施例中，滤网61与环形主体部60通过注塑一体成型。在本实施例的变换例中，滤网61也可以固设于环形主体部60的端面上。
由上述分析可知，过滤器6除了具备过滤作用之外，其环形主体部60还兼具弹簧座的作用，因而机油控制阀中不用再单独设置弹簧座，简化了机油控制阀的结构、降低了机油控制阀的成本。
结合图4至图6所示，在本实施例中，环形主体部60与阀体2的内周面过盈配合，使得环形主体部60的外周面S1与阀体20的内周面能够无缝隙贴合，并能够很好的防止液压油未经过滤就从过滤器6与阀体2内周面之间的间隙流向阀体2内。在其他实施例中，环形主体部60与阀体2的内周面也可以为过渡配合。
环形主体部60还设有：环形第二凹槽620，位于环形主体部60背向压缩弹簧5的端面，第二凹槽620的侧壁设有沿环形主体部60周向均匀间隔排列的多个开口630，开口630沿径向贯穿环形主体部60，并与第二凹槽620连通。
结合图5和图7所示，过滤器6还包括：位于第二凹槽620内的卡簧63，凸起62在卡簧63的径向外侧与其一体成型。在本实施例中，凸起62的数量为多个，多个凸起62沿卡簧63的周向均匀间隔排列。凸起62穿过开口630，并突出于环形主体部60的外周面S1。凸起62沿卡簧63周向的宽度尺寸稍小于开口630沿环形主体部60周向的宽度尺寸。
卡簧63与现有技术的卡簧结构相同，呈C型(即未封闭的环形)，沿周向的两端设有两个通孔630。卡簧63由弹簧钢制成，因而具有弹性。
在组装本实施例的机油控制阀之前，可以先将一体成型的卡簧和凸起弹性安装至环形主体部内。结合图5至图7所示，具体地，利用 卡簧钳压缩卡簧63，使其外径减小；然后，将与凸起62一体成型的卡簧63放入第二凹槽620内，待凸起62沿径向对准开口630之后，松开卡簧钳，卡簧63恢复形变，凸起62穿过开口630。
下面结合图5对本实施例的机油控制阀的组装方法作具体介绍。
首先，将压缩弹簧5自进油口I安装至阀体2内；
接着，将过滤器6自进油口I塞入阀体2内，凸起62沿径向向外突伸入卡槽20内，且环形主体部60远离进油口I的端面抵靠压缩弹簧5，使压缩弹簧5呈压缩状态。
结合图4至图5所示，在将过滤器6塞入阀体2内的过程中：首先，利用卡簧钳压缩卡簧63，当凸起62未从开口630伸出环形主体部60的外周面S1使，将过滤器6塞入阀体2内，并松开卡簧钳；接着，待过滤器6塞入至凸起62与卡槽20对准的位置时，卡簧63恢复形变，使得凸起62自环形主体部60的外周面S1伸入卡槽20内。
由上述可知，在组装机油控制阀时，可以直接将整个过滤器6安装至阀体20内，无需逐个安装弹簧座、过滤器，简化了组装工序，缩短了组装周期。
在本实施例中，如图4所示，阀体2在进油口I处设有内倒角21，这样一来，能够更为容易的将过滤器6自进油口I塞入阀体2内。
在本实施例中，环形主体部60的材料为塑料。这样一来，可以利用注塑成型工艺形成环形主体部60。在获得同样加工精度的条件下，利用注塑成型工艺制作环形主体部60所花费的成本低于冲压工艺，有利于降低机油控制阀的制造成本。另外，由于塑料一般具有一定弹性，因此，更容易将过滤器6自进油口I塞入阀体2内。
进一步地，该塑料为PA66系列塑料，其能够很好的与机油控制阀的工作环境兼容。
将过滤器6从阀体2上拆卸下来时，利用卡簧钳压缩卡簧63， 使得凸起62未伸入卡槽20内；然后，将过滤器6从阀体2内取出。在拆卸过滤器6的过程中，过滤器6并未被破坏，还可以重复使用。
第二实施例
第二实施例与第一实施例之间的区别在于：在第二实施例中，如图10所示，凸起62固设于环形主体部60的外周面S1，过滤器6未设置卡簧，环形主体部60未设置开口。在具体实施例中，凸起62与环形主体部60一体成型。
凸起62在环形主体部60的周向上未环抱整个环形主体部60，沿周向相邻的两个凸起62之间有间隔。结合图8至图9所示，为了防止液压油未经过滤就从该间隔流向阀体2内，环形主体部60的外周面S1与阀体2的内周面贴合。
与第一实施例不同的是，在本实施例中，在将过滤器6安装至阀体2内时，可以直接将整个过滤器6塞入阀体2内，不用借助卡簧钳。
结合图9至图10所示，凸起62具有面向阀体2内周面的斜坡面S2，斜坡面S2未与环形主体部60的外周面S1相连，沿自过滤器6至压缩弹簧5的轴向方向，斜坡面S2沿径向向内倾斜，使得自过滤器6至压缩弹簧5的轴向方向，斜坡面S2与环形主体部6中轴线之间的垂直距离逐渐减小。在安装过程中，斜坡面S2起引导作用，不仅便于过滤器6自进油口I塞入阀体2内，也便于凸起62伸入卡槽20内。
在本实施例的变换例中，凸起62在环形主体部60的周向上环抱整个环形主体部60，环形主体部60的外周面S1与阀体2的内周面存在间隙。由于凸起62沿阀体2轴向抵靠卡槽20的槽壁，且凸起62为环形，能够实现过滤器6与阀体2无缝隙贴合，不会出现液压油未经过滤就流向阀体2内的问题。另外，由于环形主体部60的外周面S1与阀体2的内周面存在间隙，使得整个过滤器6更容易塞入阀体2内。
当然，当凸起62在环形主体部60的周向上环抱整个环形主体部60时，环形主体部60的外周面S1也可以与阀体2的内周面贴合。
与第一实施例相比，第二实施例的技术方案具有以下优点：过滤器中不用设置卡簧，简化了机油控制阀的结构、降低了机油控制阀的成本，简化了机油组装工序，缩短了组装周期。
与第二实施例相比，第一实施例的技术方案具有以下优点：在将过滤器从阀体上拆卸下来时，过滤器并未被破坏，还可以重复使用。
本发明中，各实施例采用递进式写法，重点描述与前述实施例的不同之处，各实施例中的相同部分可以参照前述实施例。
虽然本发明披露如上，但本发明并非限定于此。任何本领域技术人员，在不脱离本发明的精神和范围内，均可作各种更动与修改，因此本发明的保护范围应当以权利要求所限定的范围为准。
