Description

一种可实现转子发动机不同压缩比的执行机构 技术领域
本发明涉及动力机械系统的技术领域，尤其涉及一种可实现转子发动机不同压缩比的执行机构。
背景技术
压缩比是指发动机的气缸总容积与燃烧室容积的比值。在内燃机的设计领域，是控制内燃机做功、爆震和排放的重要参数。传统发动机的压缩比是不可变动的，因为燃烧室容积及气缸工作容积都是固定的参数，在设计中已经定好。由发动机的理论循环可知，增大压缩比可以提高发动机的指示热效率，改善发动机的动力性、经济性及排放性，同时提高发动机的冷启动性能。但压缩比过大会增加发动机的机械负荷、热负荷和爆震的可能性，降低发动机的工作可靠性及使用寿命。特别是在涡轮增压器在发动机的应用以后，以上二者之间的矛盾更加凸显。这主要是因为，在增压发动机中，为了防止爆震，其压缩比要低于自然吸气式发动机。涡轮增压发动机实际工作过程中，增压系统需要在发动机达到一定转速的情况下才会起作用，形成所谓的增压滞后现象。所以，在发动机低转速工况下，增压系统是没有起到作用的，而增压发动机的压缩比又比自然自然吸气式发动机低，所以就造成增压发动机在低速时扭矩上升非常缓慢。而在发动机高转速工况下，增压发动机的增压系统工作后，随着进气量的增加，发动机内的充量系数增加，燃烧效率大大增加，这就导致增压发动机缸内比较容易出现爆震现象(也称“敲缸”现象)，同时增加发动机的机械负荷和热负荷，这对发动机的可靠性也非常不利。为了解决以上不同工况对压缩比要求的矛盾，本发明设计了一种用于转子发动机上的可变压缩比机构，其可实现随着工况的变化连续调节压缩比，以便能够从低转速到高转速整个工况范围内都能保证最佳的压缩比，从而克服了传统转子发动机压缩比不可变的缺陷，有利的提高了转子发动机的性能。

具体实施方式
下面结合附图以及具体实施例对本发明作进一步的说明，但本发明的保护范围并不限于此。
结合图1、图2和图3，一种可实现转子发动机不同压缩比的执行机构，包括偏心轴部分1，三角转子部分2和控制系统；所述偏心轴部分1包括偏心轴前部9、电动三爪组合体12和偏心轴后部14；所述电动三爪组合体12包括电动三爪前端盖10与电动三爪11，所述电动三爪11通过控制系统控制所述电动三爪11的爪顶伸缩距离；所述电动三爪11的每个爪顶装有内支撑弧块13；所述偏心轴前部9和偏心轴后部14上设有偏心圆台，所述偏心轴前部9设有第二通孔19内部固定控制所述电动三爪11的导线；通过第二螺栓3将偏心轴前部9、电动三爪组合体12和偏心轴后部14固定连接，使所述偏心轴前部9的偏心圆台与所述偏心轴后部14的偏心圆台同轴；所述三角转子部分2包括变容执行机构，转子前部4和转子后部8；所述转子前部4和转子后部8外表面设有转子凹坑20，且内部设有环形槽21，所述转子凹坑20通过第一通孔17与所述环形槽21相 贯通；所述转子凹坑20为方形槽；所述转子前部4和转子后部8通过第一螺栓25紧固安装，使所述转子前部4的转子凹坑20与转子后部8的转子凹坑20对齐；所述变容执行机构安装在所述环形槽21内；所述变容执行机构包括变容板5和外支撑弧块6，所述变容板5通过连接圆柱7与所述外支撑弧块6固定；所述变容板5上固定收缩弹簧15一端，所述收缩弹簧15另一端固定在所述转子凹坑20内；所述外支撑弧块6放置在所述环形槽21内；所述控制系统包括三爪电控系统18和旋转接头16；所述旋转接头16一端与所述第二通孔19内导线相连，另一端与三爪电控系统18相连，通过三爪电控系统18控制所述电动三爪11；所述偏心轴部分1穿过所述三角转子部分2，使所述电动三爪组合体12放置在所述环形槽21内，通过所述电动三爪11的爪顶伸缩使得所述变容执行机构做往复运动。
由于所述第二通孔19内导线连接于电动三爪上，即第二通孔19内的导线在发动机实际工作中是和整个偏心轴部分1一起做旋转运动，所以第二通孔19内的导线采用硬质导线，并且该导线通过旋转接头16与连接电控系统的导线相连接，使得连接电控系统的导线不发生扭转，从而保护了电控系统的正常运转。
具体工作过程为：根据不同工况下的压缩比要求，由三爪电控系统18控制电动三爪的伸缩量。当需要增大压缩比时，电动三爪11的爪伸出，通过内支撑弧块13带动变容执行机构运动，从而使转子凹坑20体积减小；当需要减小压缩比时，电动三爪11回缩，同时变容执行机构由安装在转子凹坑20内的收缩弹簧15拉回，从而使转子凹坑20体积增大。
由于所述的变容板5在转子凹坑20内做往复运动需要采取密封措施，结合图4和图5所示，故所述变容板5四周设有密封槽，所述密封槽内部装有波形弹簧23，所述波形弹簧外装有与转子凹坑20密封的密封片24。
结合图6所示，在三角转子发动机工作时，主轴与三角转子的转速不同，故内支撑弧块13与外支撑弧块6之间虽然始终贴在一起，但是存在着相对转动，为了保证其在工作时不产生干涉，所述外支撑弧块6的两端斜边向外倒角，使得所述外支撑弧块6截面外弧长大于内弧长。所述内支撑弧块13的两端斜边向内倒角，使得所述内支撑弧块6截面外弧长小于内弧长。
所述实施例为本发明的优选的实施方式，但本发明并不限于上述实施方式，在不背离本发明的实质内容的情况下，本领域技术人员能够做出的任何显而易见的改进、替换或变型均属于本发明的保护范围。
