第二转子23一面固接有转轴29，在转轴29周围至少分布有三个滚珠槽 28，本实施例中有三个滚珠槽。第二转子23外围至少有一个同所述第二轴臂 孔之凸体42配合的凹体43，本实施例中有三个凹体。第二转子23中的转轴 29穿设在第二定子22中的轴孔38内，第二定子22滚珠槽28与第二转子23 滚珠槽28合在一起形成滚珠盒，每个滚珠盒中放有第二滚珠30；第二转子 23装在所述第二轴臂孔27中。
所述滚珠槽28为一端由深到浅延伸至另一端，为斜面逐渐过渡结构。
见图3-6，A表示深槽处，B为浅槽处，从深槽处A延伸至浅槽处B，为 斜面逐渐过渡。第一定子18、第一转子20之滚珠槽28以顺时针由浅至深过 渡。第二定子23、第二转子22之滚珠槽28以顺时针由深至浅过渡。
第一定子、第二定子、第一转子、第二转子为圆形状，第一轴臂孔、第 二轴臂孔为圆形孔。第一转子、第二转子分别能装入第一轴臂孔、第二轴臂 孔中，并且第一转子、第二转子分别能在第一轴臂孔、第二轴臂孔中轴向移 动。
第二制动组件3中，所述第二轴臂孔27内至少有一凸体42，第二转子 23外围至少有一同所述凸体42配合的凹体43，第二转子23装入第二轴臂孔 27中，凸体42与凹体43扣合一起，本实施例为三个凸体与凹体。双轴连杆 21转动时才会带第二转子转动。也就是说，因受到凸体与凹体限制，第二转 子只能同双轴连杆一起旋转，同时，第二转子还可以在第二轴臂孔单独轴向 移动，第一制动组件2与之原理相同。
在刹车线连接部1中固定刹车线130，当拉动刹车线时，带动双轴连杆 21转动，第一转子20也会随之转动，由于第一定子18固定不动的，第一转 子20在转动时会使第一滚珠19向斜面的浅槽处移动，这样，当第一转子20 因受到第一滚珠19挤压时，第一转子20在第一轴臂孔26内向内移动，并推 动刹车片紧压刹车碟盘。以此同时，另一边第二转子23因受到第二滚珠30 挤压时，第二转子23在第二轴臂孔27内向内移动，并推动刹车片紧压刹车 碟盘，这样，就成为双边制动。
本发明并不是一个完整的机械碟刹，而是机械碟刹中的一个驱动刹车片 的组件。本发明为金属材料。
见图7、8，并参见图16，使用本发明时，第一定子18与第二定子23要 分别固定在机械碟刹的壳体中，第一定子18装在第一定子安装孔202中，第 二定子22装在第二定子安装孔150中。在第一转子20与第二转子23内一面 放置刹车片7，刹车片定位弹件70将刹车片7分别固定在第一转子20与第 二转子23内一面。使用时，刹车碟盘16是设在两个刹车片7之间的。
本实施例解决双轴连杆复位采用方法：见图7、8，在刹车线连接部1与 刹车线调节螺栓13之间的刹车线130中设有第三复位弹簧702。刹车时，刹 车线连接部1向刹车线调节螺栓13方向移动时，第三复位弹簧702受到挤压， 当不刹车时，刹车线松开，第三复位弹簧702到回原位。
双轴连杆另一复位方法：见图9，第四复位弹簧703安装在刹车线连接 部1下端，其原理与上述相同。
实施例2：
见图10、11，第一定子18与第二定子结构相同，第一转子20与第二转 子结构相同，本实施例与实施例1不同的是：以第一定子18、第一转子20 为例说明。A表示深槽处，B为浅槽处，从深槽处A延伸至浅槽处B，为斜面 逐渐过渡，第一定子18之滚珠槽28以顺时针由深至浅过渡。第一转子20之 滚珠槽28以顺时针由浅至深过渡。本实施例不是最佳方案，因为在使用时， 第一转子受挤压移位距离较短，会造成刹车片在刹车碟盘中的制动效果差。
实施例3：
见图12-16，本实施例与实施例1不同的是：第一定子18外侧有第一弹 簧孔位504(图14)，第一复位弹簧401装在第一弹簧孔位504内，在第一复 位弹簧401外面有第一弹簧固定盖402及卡环203，第一弹簧固定盖402中 间具有通孔，所述第一转子20之转轴29中有一卡槽290，转轴29依次穿过 第一定子18之轴孔38、第一复位弹簧401、第一弹簧固定盖402后，一卡环 203扣合于卡槽290中。
所述第二定子22外侧有第二弹簧孔位503，第二复位弹簧501装在第二 弹簧孔位503内，在第二复位弹簧501外面有第二弹簧固定盖502及卡环203， 第二弹簧固定盖502中间具有通孔；所述第二转子23之转轴29中有一卡槽 290，转轴29依次穿过第二定子22之轴孔38、第二复位弹簧501、第二弹簧 固定盖502后，一卡环203扣合于卡槽290中。
实施例1解决双轴连杆复位，是在使用时采用外加安装第三复位弹簧702 或第四复位弹簧703(见图7、9)。本实施例直接在本实施例中安装复位弹簧 (第一复位弹簧401与第二复位弹簧501)。
其过程与作用是：以第二制动组件3为例进行说明，第二复位弹簧501 为塔形，装在第二弹簧孔位503内，第二转子23之转轴29依次穿过第二定 子22之轴孔38、第二复位弹簧501、第二弹簧固定盖502后，一卡环203扣 合于卡槽290中。并见图16，第二定子22是安装在机械碟刹下盖15之第二 定子安装孔150中的，第二定子22是不动的。刹车时，双轴连杆21转动， 由于凸体42与凹体43限制作用，第二转子23会随双轴连杆21旋转，因第 二复位弹簧501被第二弹簧固定盖502压在第二弹簧孔位503内，加之，第 二转子23之转轴29被卡槽290扣紧，因此，第二转子23旋转时，第二复位 弹簧501、第二弹簧固定盖也会随第二转子23旋转，第二复位弹簧501受到 扭压，当松开刹车，因第二复位弹簧501的作用，第二转子23连同带动双轴 连杆21复为原位。
实施例不采用卡环也可以：在转轴29中设一内螺纹，第二转子23之转 轴29依次穿过第二定子22之轴孔38、第二复位弹簧501、第二弹簧固定盖 502之中间通孔后，一螺丝螺接于内螺纹中固定。另一边第一定子、第一转 子同之。
见图15、16，图15是个完整的机械碟刹，包括上盖201及下盖15，本 发明实施例3之双轴转子装置装于上盖201与下盖15之间的内腔中。第一定 子18装在第一定子安装孔202中，第二定子22装在第二定子安装孔150中。
在第一转子20与第二转子23内一面放置刹车片7，刹车片定位弹件70 将刹车片7分别固定在第一转子20与第二转子23内一面。使用时，刹车碟 盘16是设在两个刹车片之间的，见图17。
所述双轴连杆21刹车线连接部1还装有一压线板4及压线螺栓5。
所述下盖15一端设有刹车线调节螺栓13及螺母12，
上盖201与下盖15结合一体后，其一侧具有间隔，供刹车碟盘16的一 边插入上盖201与下盖15之间。
刹车线接于双轴连杆21刹车线连接部1，用压线板4压紧刹车线，压线 螺栓5穿过压线板4固接于螺孔中，刹车线再通过刹车线调节螺栓13后与自 行车上的刹车把连接。刹车线调节螺栓其作用是调节刹车线的松紧。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节， 而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实 现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且 是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨 在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。 不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
