Description

一种新型活塞环 技术领域
本发明涉及机械领域，具体地涉及一种新型活塞环。
背景技术
现有的活塞环，每个活塞环槽里装有一个活塞环，由于受到金属热胀冷缩的影响，活塞环必须留有一定的开口间隙，在发动机压缩空气与做功时，是不可避免地往曲轴箱漏气，随着活塞环与缸桶不断的磨损，环口会加大漏气量，严重降低了发动机的功率，不断增加燃油的消耗量，而泄漏到曲轴箱的废气与燃烧颗粒物，使机油快速氧化变质。曲轴箱废气管与发动机进气管相连，大量的废气又被吸入气缸燃烧，导致发动机吸入的新鲜空气减少，相当于发动机在缺氧的状态下工作，发动机燃烧效率下降。由此，造成了发动机的工作恶性循环。
泄漏气体不但使发动机功率下降，而且废气排放会加大污染环境的力度。环口泄漏的气体沿着活塞在缸内侧冲击活塞敲击气缸，增加了气缸内的磨损，还增加了发动机的噪音。大量的高温高压气体把曲轴箱的机油形成油蒸汽。油蒸汽会随着废气管进入发动机进气管，吸入气缸燃烧形成了发动机机油大量机油消耗的情况。
发明内容
为了弥补现有技术中存在的以上不足，本发明提供了一种新型活塞环，其不会导致往曲轴箱漏气情况的发生。
本发明提供了一种新型活塞环，其包括上环和位于所述上环下方的下环，所述下环包括外环和内环，所述外环和内环的厚度相等；所述上环、外环和内环同心设置；所述内环的外径等于所述外环的内径，所述上环的外径等于所述外环的外径；所述上环、外环和内环上分别设置有上环开口、外环开口、内环开口；所述上环开口、外环开口、内环开口错开设置。
进一步地，所述内环的内径等于上环的内径。
可选地，所述外环开口与上环开口错开90-180°。
优选地，所述外环开口与上环开口错开180°。
可选地，所述外环开口与内环开口错开30-120°。
优选地，所述外环开口与内环开口错开90°。
可选地，所述上环的厚度为所述外环厚度的2/3-2倍。
优选地，所述上环的厚度与所述外环的厚度相等。
本发明提供的新型活塞环，其上环、外环和内环置于同一个环槽内。使用本发明提供的新型活塞环，发动机压缩空气时，空气从上环开口下行的方向被下环阻挡，空气沿上环开口进入上下环内侧(活塞环纵向间隙)。外环开口与内环开口的上面被上环封闭，外环开口的内侧口被内环的外侧密封，内环开口的外口被外环密封。下环下平面又被活塞环槽平面密封，互相密封致使燃烧室的气体被完全封闭，克服了现所有发动机气缸往曲轴箱漏气现象。
根据本发明提供的一种新型活塞环，能够带来至少以下有益效果：
1、发动机进气时吸入的是空气，含氧量高，与燃油混合燃烧充分，热效高，尾气更环保；
2、气缸空气压缩与做功时不漏气，发动机扭矩增加；
3、简化了发动机废气通道，PCV阀可以去掉，节省发动机制造成本；
4、机油不受废气与燃烧的颗粒物的污染，更好地改善了发动机的润滑条件，增加了发动机使用寿命，换机油周期延长了1倍以上，机油的滤芯可以做成细密的不锈钢滤网永久使用，而不换机油滤芯，大量节省了发动机保养成本；
5、发动机进气通道与气门不再因机油蒸汽形成积碳造成发动机的进气阻力降低动力，从而节省了维修成本；
6、没有环口漏气，活塞上下运行稳定，磨损小、噪音低，发动机使用寿命延长；
7、随着发动机的运转，即使活塞环的开口间隙与气缸的磨损加大也不会漏气，动力不衰减；
8、发动机低速扭矩大，可以低转速让车辆以更高的速度行驶，大量节省了燃油，减少了能源消耗；
9、活塞可以一道气环一道油环，降低了活塞高度，节约了发动机的制造成本；
10、这种组合环也可安装在空压机上、液压设备上，其具有耐高温、耐磨损、应用范围广的特点；
11、所有的车辆新发动机均可安装此活塞环，安装后动力立刻增加；
12、克服了现有涡轮发动机由于活塞环漏气量大而导致曲轴箱通风管窜机油烧机油现象；
13、可以制造生产出缸筒活塞式空气弹簧，克服了现有的橡胶密封空气弹簧不耐压、不耐用的问题。
附图说明
为了更清楚地说明本发明具体实施方式或现有技术中的技术方案，下面将对具体实施方式或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的新型活塞环的组合前结构示意图；
图2为上环的结构示意图；
图3为本发明实施例提供的新型活塞环的组合后结构示意图。
附图标记：
上环1，外环2，内环3，上环开口11，外环开口21，内环开口31。
具体实施方式
下面参照附图详细介绍本发明的示例性实施例。提供这些示例性实施例的目的是为了使得本领域普通技术人员能够清楚地理解本发明，并且根据这里的描述能够实现本发明。附图和具体实施例不旨在对本发明进行限定，本发明的范围由所附权利要求限定。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
实施例1
参照图1至图3，本实施例提供了一种新型活塞环，其包括上环1和位于该上环1下方的下环，该下环包括外环2和内环3，外环2和内环3的厚度相等，上环1的厚度与外环2的厚度相等；上环1、外环2和内环3同心设置；内环3的外径等于外环2的内径，上环1的外径等于外环2的外径，内环3的内径等于上环1的内径。
上环1、外环2和内环3上分别设置有上环开口11、外环开口21、内环开口31。外环开口21与上环开口11错开180°，外环开口21与内环开口31错开90°。
将实施例1提供的活塞环用于旧摩托车上。实验前发动机加速无力，还有活塞敲缸声音，拆开后活塞一侧敲击缸壁，活塞顶部有很明显的磨损，缸壁有轻微拉伤。缸套与活塞都不换，原活塞环宽2毫米、厚1毫米，直接把活塞环槽加宽到装两层活塞环的高度。原活塞环作为上环，又买了两个活塞环，加工后作为下环；新买的活塞环，其中一个打磨内侧0.5毫米，另一个打磨外侧1.5毫米；打磨外侧1.5毫米的活塞环作为内环，打磨内侧0.5毫米的活塞环作为外环，根据实施例1要求的各开口的错开角度，将活塞环安装于环槽内。
组装完后压缩明显增强，排气管声音加大，声音浑厚，动力非常强劲。加速时敲缸声音消除；发动机运转声音降低。风冷发动机的工作环境是最恶劣的，经常是高速运转，试用一年半，未出现任何问题。
需要说明的是，申请人为防止本发明的活塞环结构因泄漏而被公开，本实施例1中采用手工制作的内环3与外环2，如果内环3与外环2用专业的加工设备做出来效果会更好。
实施例2
本实施例提供了一种新型活塞环，其包括上环1和位于该上环1下方的下环，该下环包括外环2和内环3，外环2和内环3的厚度相等，上环1的厚度为外环2的厚度的4/5；上环1、外环2和内环3同心设置；内环3的外径等于外环2的内径，上环1的外径等于外环2的外径，内环3的内径等于上环1的内径。
上环1、外环2和内环3上分别设置有上环开口11、外环开口21、内环开口31。外环开口21与上环开口11错开150°，外环开口21与内环开口31错开60°。
实施例3
本实施例提供了一种新型活塞环，其包括上环1和位于该上环1下方的下环，该下环包括外环2和内环3，外环2和内环3的厚度相等，上环1的厚度为外环2的厚度的1.5倍；上环1、外环2和内环3同心设置；内环3的外径等于外环2的内径，上环1的外径等于外环2的外径，内环3的内径等于上环1的内径。
上环1、外环2和内环3上分别设置有上环开口11、外环开口21、内环开口31。外环开口21与上环开口11错开160°，外环开口21与内环开口31错开100°。
事实上，外环开口21与上环开口11错开90-180°之间的任意值均可，外环开口21与内环开口31错开30-120°之间的任意值均可；只要上环开口11、外环开口21、内环开口31互不重叠即可。
另外，上环1的厚度为外环2厚度的2/3-2倍之间的任意数值均可，根据不同发动机类型以及其他具体情况确定两者的厚度关系。当然，本发明的新型活塞环，上环厚度与下环厚度之和大于等于现有技术中单环的活塞环厚度；当上环厚度与下环厚度之和大于现有技术中单环的活塞环厚度时，将环槽变宽即可。
本发明的新型活塞环并不限定于某特定的材料，但优选地，要求材料弹性好、刚性强度大。球墨铸铁材料容易断不可以用它来制造。现在的活塞若装这种活塞环则必须加粗环槽，才能装这种活塞环，外环开口随着磨损环口间隙的加大，上环太薄了容易被高温高压气体在外环开口冲断。如果把第二道活塞环取消，只用一道新型活塞环，新型活塞环的润滑环境更好更耐磨。如果缸套上部20毫米高度完全激光淬火加硬处理，发动机的使用寿命就更长了。
需要注意的是外环与内环要严密地贴合，若贴合不严则有被高压气体冲断的可能；拉缸问题，在高速运转测试中，风冷发动机毕竟散热效果差，机油沸腾后从废气管涌出，也没有出现拉缸现象。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
