发明内容
本发明为了解决现有无级变速传动结构钢带易损坏、 结构复杂、 以及 维护不便的问题， 提供了一种无级变速器的机械运行结构。
本发明是采用如下技术方案实现的： 无级变速器的机械运行结构， 包 括中心轴； 中心轴的外侧面中部环向设置有齿槽段； 中心轴的外侧面配合 有轴套； 轴套的外侧面开设有若干个轴向限位槽； 各个轴向限位槽内均嵌 设有一个连接板； 各个连接板的内端端面上均设置有一个圆弧形轮齿段； 各个圆弧形轮齿段均与齿槽段相互啮合； 各个连接板的侧面均安装有一个 枢轴； 各个连接板分别通过各个枢轴一一对应铰接于各个轴向限位槽的槽 壁上。
工作过程如下： 进行变速时， 沿轴套的轴线方向移动中心轴或移动轴 套， 使得中心轴与轴套之间发生相对运动。 在相对运动和相互啮合的圆弧 形轮齿段和齿槽段共同作用下， 连接板沿轴套的轴线方向进行翘翘板式的 运动 （如图 15、 图 16所示）， 由此达到了变速目的。 在此基础上， 通过将 两个所述的无级变速器的机械运行结构进行串联（如图 17所示）或者并联 (如图 18所示）， 可以实现多种变速目的。 基于上述过程， 与现有无级变 速传动结构相比， 本发明所述的无级变速器的机械运行结构基于全新的变 速结构和原理， 避免了钢带损坏的问题， 同时其结构更加简单， 维护更加 方便。
本发明基于全新的变速结构和原理， 有效解决了现有无级变速传动结 构钢带易损坏、 结构复杂、 以及维护不便的问题， 适用于汽车变速。
