Description

离心爪式离合器
技术领域
本发明涉及一种离合器，特别是涉及一种离心爪式离合器。
背景技术
现有摩擦块式离合器的体积大，成本高，要外加旋转接头才能使用；摩擦块尺寸大，传递扭矩小，摩擦材料为石棉，容易摩损，优点是可以在发动机不停机的情况下自由的分离和结合，操作员误操作时不会损坏离合器。且无法做到单向传递扭矩，低速现有结构的离心式离合器时传递扭矩很小。
发明内容
本发明为了解决上述问题提供了离心爪式离合器，克服了现有技术的不足，设计简单，结构合理，内圈离心爪的凹槽内各布置一对滚柱，在滚柱和离心爪之间置有耐磨片，压簧通过顶销向滚柱施加压力。内圈转动时离心力使内侧的滚柱向外移动，推挤柱销一侧的滚柱向柱销一侧移动，当达到一定转速时滚柱离心力克服顶销弹力，向内圈的离心爪和外圈形成的夹角内挤入，产生自锁角，离合器自锁从而使的内圈带动外圈转动，转速下降时离心力降低，顶销将滚柱推离自锁角，滚柱自由转动，本离合器在使用过程中具有高度耐磨、使用寿命长、低噪音、低油耗量和传动效率搞的优点。
本发明采用的技术方案如下：
离心爪式离合器，包括内圈，外圈，顶销，压簧，滚柱，其特征在于：所述内圈外形为离心爪，所述顶销安装在内圈离心爪上顶住滚柱，所述压簧安装在内圈离心爪上为顶销提供弹力；所述滚柱内圈之间的接触点置有钨钢耐磨片；所述外圈的和内圈离心爪凹槽面之间有夹角；所述外圈上留有通孔可连接联轴器；所述内圈上置有键槽可连接发动机。
与已有技术相比，本发明的有益效果如下：
本发明提供的离心爪式离合器结构合理，防卡死，节省能源；在使用过程中具有低速时高扭矩、使用寿命长、低噪音的优点。
附图说明
图1为本发明的工作状态结构示意图。
图2为本发明的非工作状态结构示意图。
图3为本发明的内圈示意图。
具体实施方式
参见附图，爪式离合器，包括内圈7，外圈6，顶销1，压簧3滚柱一2，滚柱二4，其特征在于：所述内圈外形为离心爪，所述顶销安装在内圈离心爪上顶住滚柱，所述压簧安装在内圈离心爪上为顶销提供弹力，所述滚柱一可延内圈凹槽面横向移动，所述滚柱二可在内圈凹槽内径向移动，工作时滚柱二向外移动，所述滚柱内圈之间的接触点置有钨钢耐磨片5。
