Description

一种可控双向同轴离合器 所属技术领域
本发明属于可控离合器技术领域，尤其涉及一种可控双向同轴离合器。
背景技术
目前使用的一般离合器为具有合上和脱离两种状态的简单离合器，还有超越离合器，在单向超越离合器基础上增加了方向切换，整个结构较为复杂，不便于小型化使用。例如带花键槽的小轮内套，小轮内套外套有小轮外套，小轮内套上开有半圆柱孔，半圆柱孔内安装有小轮棘齿，小轮内套上还开有弹簧孔，弹簧孔内插有小轮弹簧钢丝，小轮棘齿的自由端与小轮弹簧钢丝的端部相接触，小轮棘齿的自由端位于小轮弹簧钢丝的外部，小轮外套的内表面设计有小轮牙齿，小轮棘齿与小轮牙齿相齿接，小轮外套内装有滚珠，小轮外套上盖有小轮端盖，使用此种结构时，小轮内套主动正转，小轮棘齿嵌入小轮牙齿而锁定，带动小轮外套正转，反之，若小轮外套主动正转，小轮棘齿则被小轮外套内的小轮牙齿排挤出去而不能锁定，则小轮内套不能随之转动，也就是说只能一个方向运转，如需要两个方向运转，则需要安装两个，使用麻烦，结构复杂，本发明意在提供一种结构简单，能够实现双向离合的机构。
本发明设计一种可控双向同轴离合器解决如上问题。
发明内容
为解决现有技术中的上述缺陷，本发明公开一种可控双向同轴离合器，它是采用以下技术方案来实现的。
一种可控双向同轴离合器，其特征在于：它包括第一轴套、固定轴、第一切换筒壁、第二切换筒壁、第二固定盘、转盘、卡槽、齿轮环、第一固定盘、第一卡块、第一卡座、横向滑块、第二卡块、卡块复位弹簧、滑块复位块、滑块复位弹簧、导环、转盘凸环、导环槽、卡座槽、复位块腔、滑块腔、卡块滑槽、卡块导块、卡块斜面、卡块限位板、卡块凹弧面，其中第一固定盘通过第一轴套安装在固定轴一端，第一切换筒壁安装在第一固定盘上；第二固定盘通过第二轴套安装在固定轴另一端，第二切换筒壁安装在第二固定盘上，第一轴套与第二轴套均可以在固定轴上滑动；转盘安装在固定轴上且位于第一切换筒壁和第二切换筒壁之间；转盘外缘面上并列安装有两个转盘凸环，转盘外缘面上并列开有两个卡座 槽，卡座槽下侧开有连接两个卡座槽的滑块腔，滑块腔下侧开有复位块腔；两个卡座分别安装在横向滑块两端，滑块复位块安装在横向滑块下侧，每个卡座内部对称地开有两个卡块滑槽，第一卡块与第二卡块的两侧均对称地安装有两个卡块导块，第一卡块通过卡块导块与卡块滑槽的滑动配合安装在两个卡座的其中一个卡座中，第二卡块通过卡块导块与卡块滑槽的滑动配合安装在两个卡座的另外一个卡座中；第一卡块底端与其卡座底端、第二卡块底端与其卡座底端之间均安装有卡块复位弹簧；横向滑块滑动于滑块腔中，滑块复位块滑动于复位块腔中且滑块复位块两侧均安装有滑块复位弹簧，两个卡座分别滑动于两个卡座槽中；第一卡块顶端沿两个卡块导块安装方向开有卡块斜面，在卡块斜面两侧均开有卡块凹弧面，第二卡块除卡块斜面倾斜方向与第一卡块相反外，其他结构与第一卡块结构相同；转盘外缘面中间还开有导环槽，齿轮环内缘面中间安装有导环，且在导环两侧还对称地开有两排卡槽，齿轮环通过导环与导环槽的配合安装在转盘上，第一卡块、第二卡块均与卡槽配合；第一切换筒壁和第二切换筒壁分别与第一卡块和第二卡块的卡块凹弧面配合。

具体实施方式
如图1、2、3所示，它包括第一轴套、固定轴、第一切换筒壁、第二切换筒壁、第二固定盘、转盘、卡槽、齿轮环、第一固定盘、第一卡块、第一卡座、横向滑块、第二卡块、卡块复位弹簧、滑块复位块、滑块复位弹簧、导环、转盘凸环、导环槽、卡座槽、复位块腔、滑块腔、卡块滑槽、卡块导块、卡块斜面、卡块限位板、卡块凹弧面，其中如图4、3所示，第一固定盘通过第一轴套安装在固定轴一端，第一切换筒壁安装在第一固定盘上；第二固定盘通过第二轴套安装在固定轴另一端，第二切换筒壁安装在第二固定盘上，第一轴套与第二轴套均可以在固定轴上滑动；如图3所示，转盘安装在固定轴上且位于第一切换筒壁和第二切换筒壁之间；如图5所示，转盘外缘面上并列安装有两个转盘凸环，如图6所示，转盘外缘面上并列开有两个卡座槽，卡座槽下侧开有连接两个卡座槽的滑 块腔，滑块腔下侧开有复位块腔；如图7、8所示，两个卡座分别安装在横向滑块两端，如图5所示，滑块复位块安装在横向滑块下侧，如图10所示，每个卡座内部对称地开有两个卡块滑槽，如图11所示，第一卡块与第二卡块的两侧均对称地安装有两个卡块导块，如图7所示，第一卡块通过卡块导块与卡块滑槽的滑动配合安装在两个卡座的其中一个卡座中，第二卡块通过卡块导块与卡块滑槽的滑动配合安装在两个卡座的另外一个卡座中；如图9所示，第一卡块底端与其卡座底端、第二卡块底端与其卡座底端之间均安装有卡块复位弹簧；横向滑块滑动于滑块腔中，滑块复位块滑动于复位块腔中且滑块复位块两侧均安装有滑块复位弹簧，两个卡座分别滑动于两个卡座槽中；第一卡块顶端沿两个卡块导块安装方向开有卡块斜面，在卡块斜面两侧均开有卡块凹弧面，如图8所示，第二卡块除卡块斜面倾斜方向与第一卡块相反外，其他结构与第一卡块结构相同；转盘外缘面中间还开有导环槽，如图12所示，齿轮环内缘面中间安装有导环，且在导环两侧还对称地开有两排卡槽，齿轮环通过导环与导环槽的配合安装在转盘上，第一卡块、第二卡块均与卡槽配合，第一切换筒壁和第二切换筒壁分别与第一卡块和第二卡块的卡块凹弧面配合。
上述齿轮环外缘面上具有齿。
上述卡块复位弹簧为压缩弹簧。
上述滑块复位弹簧为拉伸弹簧。
上述齿轮环外缘面上具有皮带槽。
综上所述，本发明中转盘可以在固定轴上旋转，齿轮环通过卡槽与卡块的配合带动转盘旋转，同样转盘也可以通过卡块与卡槽的配合带动齿轮环旋转，横向滑块附带两个卡座、卡块在滑块腔中滑动，同时卡座在卡座槽中横向滑动，同时滑块复位块在两侧的滑块复位弹簧作用下在复位块腔中滑动，齿轮环两侧具有两排卡槽，卡块可以与其中任意一个卡槽形成限位配合作用。切换筒壁对卡块的卡块凹弧面作用，一方面壁对卡块、卡座、横向滑块施加一定的力使卡块、卡座、横向滑块整体沿着滑块腔移动到滑块腔的一侧，另一方面第一卡块被第一切换筒壁沿卡块滑槽向里压下，这两方面引起的效果是，通过控制切换筒壁的移动来控制转盘与齿轮环的传动方向，实现可控双向离合器的作用，具有较好的使用效果。
具体实施方式如下：当转盘在自由非工作状态下时，横向滑块在两侧的滑块 复位弹簧作用下位于中间位置，此时两个卡座分别位于两个卡座槽的中间位置，卡块在卡块复位弹簧作用下处于平衡状态，第一卡块与第二卡块顶端均一半卡入齿轮环卡槽中。当第一切换筒壁向转盘移动且与第一卡块接触后，且接触到卡块凹弧面半腰位置，一方面壁对卡块、卡座、横向滑块施加一定的力使卡块、卡座、横向滑块整体沿着滑块腔移动到滑块腔的一侧，另一方面第一卡块被第一切换筒壁沿卡块滑槽向里压下，这两方面引起的效果是第二卡块被移出齿轮环内缘面，第二卡块将不会与卡槽配合，第二卡块失去了对齿轮环的卡位作用，另外第一卡块被压下后，因为第一切换筒壁只接触到第一卡块的凹弧面半腰，所以卡块斜面较低的一端被压到卡座内，卡块斜面较高的一端仍然在卡座上部，这样的设计可以使齿轮环与转盘单向传动。将第一切换筒壁向外推开，转而将第二切换筒壁移动接触到第二卡块，将使齿轮环与转盘再一次发生单向传导，此次单向传导的方向与上一次单向传导的方向相反，原理相同，实现了可控的双向的单向传导。
