压力弹簧26一端抵住轮子座29，通过轮子座29作用在压杆25上，即压力弹簧26一端作用在压杆25上，另一端抵住固定锥盘悬臂20，当轮子28落在凸轮30的a：啮合区47时，压力弹簧26伸长；当轮子28落在凸轮30的c：分离区50时，轮子28被凸轮30顶起，压力弹簧26被压缩。
链条34由链条轴12、链条轴轮7、链片9、链条边片6组成。
特例一：在滑车3中，只有活动摩擦片(链轮)8和固定摩擦片10，它们可以间隔存在，并没有活动摩擦片一11。

该无级变速器工作原理
1、动力传递工作过程：
动力从输入轴42进入变速器，在a：啮合区47的滑车3上，弹簧26的弹力把活动摩擦片(链轮)8和固定摩擦片10压紧在滑车3上，即活动摩擦片(链轮)8通过滑车3分别被固定在一对主动锥盘和一对被动锥盘上，也就是链条34分别与一对主动锥盘的活动摩擦片(链轮)8和一对被动锥盘的活动摩擦片(链轮)8啮合，输入轴42带动一对主动锥盘转动，一对主动锥盘通过一对主动锥盘上的活动摩擦片(链轮)8、链条34和一对被动锥盘上的活动摩擦片(链轮)8带动一对被动锥盘转动，再带动输出轴31转动，输出动力。
2、调速过程：调速丝杠43转动，带动调速杠杆40摆动，调速杠杆40带动限位器1来回移动，限位器1带动移动锥盘2来回移动，造成滑车3带着活动摩擦片(链轮)8沿着锥盘导轨14来回滑动，造成与活动摩擦片(链轮)8配合的链条34所在的一对主动锥盘和一对被动锥盘上的工作节圆半径变化，就改变了输入轴42和输出轴31转速速比，实现变速器的速比变化，实现了变速器的调速。
3、活动摩擦片(链轮)8被压紧在滑车3上，与滑车3成为一体的工作过程：
(1)当轮子28落在凸轮30的a：啮合区47时，在压力弹簧26的弹力作用下，活动摩擦片(链轮)8、固定摩擦片10、活动摩擦片一11和滑车3被压紧，成为一体，活动摩擦片(链轮)8与链条34啮合，传递动力。
(2)当轮子28落在凸轮30的b：正在分离区49时，轮子28被凸轮30顶起，压力弹簧26的弹力通过轮子28施加在凸轮28上，轮子28带动轮子座31、压杆25、压力铰接片二22、压力片16同时移动，压力片16脱离加压轴13，松开固定摩擦片10、活动摩擦片一11和活动摩擦片(链轮)8，造成对固定摩擦片10、活动摩擦片一11和活动摩擦片(链轮)8的压紧力的消失，活动摩擦片一11和活动摩擦片(链轮)8可以自由转动。
(3)当轮子28落在c：分离区50时，活动摩擦片一11和活动摩擦片(链轮)8不受压紧力，可以自由转动；
(4)当轮子28落在凸轮30的d：正在啮合区时，链条34和活动摩擦片(链轮)8自由搭接，压力弹簧26的弹力通过轮子座29、压杆25、压力铰接片二22、压力片16、加压轴13作用在活动摩擦片(链轮)8上，活动摩擦片(链轮)8压紧固定摩擦片10，固定摩擦片10压紧活动摩擦片一11，使活动摩擦片(链轮)8、固定摩擦片10、活动摩擦片一11和滑车3成为一体，活动摩擦片(链轮)8与链条34啮合，传递动力，即在活动摩擦片(链轮)8压紧固定摩擦片10后，活动摩擦片(链轮)8与链条34啮合，传递动力。活动摩擦片(链轮)8就是可以与链条34啮合的链轮。活动摩擦片(链轮)8中心的方孔和活动摩擦片一11中心的方孔与中心轴5方形断面形线配合，固定摩擦片10的半圆豁口与固定摩擦片定位轴46配合，滑车定位轴孔57与固定摩擦片定位轴46配合，固定摩擦片10通过固定摩擦片定位轴46与滑车3配合，固定摩擦片10只能在固定摩擦片定位轴46上滑动，不能转动。
4、特例一的运动原理，当轮子28落在凸轮30的a：啮合区47时，压力弹簧26的弹力通过轮子座29、压杆25、压力铰接片二22、压力片16、加压轴13作用在活动摩擦片(链轮)8上，活动摩擦片(链轮)8压紧固定摩擦片10，活动摩擦片(链轮)8中心的方孔与中心轴5方形断面形线配合，固定摩擦片10的半圆豁口与固定摩擦片定位轴46配合，滑车定位轴孔57与固定摩擦片定位轴46配合，固定摩擦片10通过固定摩擦片定位轴46与滑车3配合，固定摩擦片10只能在固定摩擦片定位轴46上滑动，不能转动；当轮子28落在c：分离区50时，轮子28被凸轮30顶起，压力弹簧26的弹力通过轮子28施加在凸轮28上，轮子28带动轮子座31、压杆25、压力铰接片二22、压力片16同时移动，压力片16脱离加压轴13，松开固定摩擦片10和活动摩擦片(链轮)8，活动摩擦片(链轮)8可以自由转动，与链条34自由搭接。
当加压轴13压紧活动摩擦片(链轮)8和固定摩擦片10时，活动摩擦片(链轮)8、固定摩擦片10、固定摩擦片定位轴46和滑车3固定在一起；当加压轴13松开活动摩擦片(链 轮)8和固定摩擦片10时，活动摩擦片(链轮)8和固定摩擦片10脱离，活动摩擦片(链轮)8可以自由转动。链条34上的链条轴轮7可以自由搭接上活动摩擦片(链轮)8。再当轮子28落在凸轮30的a：啮合区47时，链条34与活动摩擦片(链轮)8啮合，即链条34就可以通过活动摩擦片(链轮)8、固定摩擦片10和滑车3与固定锥盘33和移动锥盘2互相传递动力，固定锥盘33和移动锥盘2通过链条34再将动力从输入轴42传给输出轴31。
由于采用了本发明结构，使该种无级变速器具有以下有益效果是：
1.动力传输的功率和扭矩大。
2.功率损耗小。
3.实现了机械无级变速。

该无级变速器工作原理
1、动力传递工作过程：
动力从输入轴42进入变速器，在a：啮合区47的滑车3上，弹簧26的弹力把活动摩擦片(链轮)8和固定摩擦片10压紧在滑车3上，即活动摩擦片(链轮)8分别被固定在一对主动锥盘和一对被动锥盘上，也就是链条34分别与一对主动锥盘的活动摩擦片(链轮)8和一对被动锥盘的活动摩擦片(链轮)8啮合，输入轴42带动一对主动锥盘转动，一对主动锥盘通过一对主动锥盘上的活动摩擦片(链轮)8、链条34和一对被动锥盘上的活动摩擦片(链轮)8带动一对被动锥盘转动，再带动输出轴31转动，输出动力。
2、调速过程：调速丝杠43转动，带动调速杠杆40摆动，调速杠杆40带动限位器1来回移动，限位器1带动移动锥盘2来回移动，造成滑车3带着活动摩擦片(链轮)8沿着锥盘导轨14来回滑动，造成与活动摩擦片(链轮)8配合的链条34所在的一对主动锥盘和一对被动锥盘上的工作节圆半径变化，就改变了输入轴42和输出轴31转速速比，实现变速器的速比变化，实现了变速器的调速。
3、活动摩擦片(链轮)8被压紧在滑车3上，与滑车3成为一体的工作过程：
(1)当轮子28落在凸轮30的a：啮合区47时，在压力弹簧26的弹力作用下，活动摩擦片(链轮)8、固定摩擦片10、活动摩擦片一11和滑车3被压紧，已经成为一体，活动摩擦片(链轮)8与链条34啮合，传递动力。
(2)当轮子28落在凸轮30的b：正在分离区49时，轮子28被凸轮30顶起，压力弹簧26的弹力通过轮子28施加在凸轮28上，轮子28带动轮子座31、压杆25、压力铰接片二22、压力片16同时移动，压力片16脱离加压轴13，松开固定摩擦片10、活动摩擦片一11和活动摩擦片(链轮)8，造成对固定摩擦片10、活动摩擦片一11和活动摩擦片(链轮)8的压紧力的消失，活动摩擦片一11和活动摩擦片(链轮)8可以自由转动。
(3)当轮子28落在c：分离区50时，活动摩擦片一11和活动摩擦片(链轮)8不受压紧力，可以自由转动；
(4)当轮子28落在凸轮30的d：正在啮合区时，链条34和活动摩擦片(链轮)8自由搭接，压力弹簧26的弹力通过轮子座29、压杆25、压力铰接片二22、压力片16、加压轴13作用在活动摩擦片(链轮)8上，活动摩擦片(链轮)8压紧固定摩擦片10，固定摩擦片10压紧活动摩擦片一11，使活动摩擦片(链轮)8、固定摩擦片10、活动摩擦片一11和滑车3成为一体，活动摩擦片(链轮)8与链条34啮合，传递动力，即在活动摩擦片(链轮)8压紧固定摩擦片10后，活动摩擦片(链轮)8与链条34啮合，传递动力。活动摩擦片(链轮)8就是可以与链条34啮合的链轮。活动摩擦片(链轮)8中心的方孔和活动摩擦片一11中心的方孔与中心轴5方形断面形线配合，固定摩擦片10的半圆豁口与固定摩擦片定位轴46配合，滑车定位轴孔57与固定摩擦片定位轴46配合，固定摩擦片10通过固定摩擦片定位轴46与滑车3配合，固定摩擦片10只能在固定摩擦片定位轴46上滑动，不能转动。
在图1中可见，在输出轴31上，一对被动锥盘距离最大，在一对被动锥盘上，链条34的工作节圆直径最小；在一对主动锥盘上，链条34的工作节圆直径最大，变速器是最大超速比。
在图2中可见，一对被动锥盘距离最小，在一对被动锥盘上，链条34的工作节圆直径最大；在一对主动锥盘上，链条34的工作节圆直径最小，变速器是最大减速比。
图3是特例四的结构，输出轴31上的移动锥盘2后有移动锥盘弹簧61，对移动锥盘2施加压力用于调速，移动锥盘弹簧61一端抵住移动锥盘2，另一端抵住移动锥盘弹簧底座62，移动锥盘弹簧底座62固定在输出轴31上；或者输入轴42上的移动锥盘2后有移动锥盘弹簧61，对移动锥盘2施加压力用于调速，移动锥盘弹簧61一端抵住移动锥盘2，另一端抵住移动锥盘弹簧底座62，移动锥盘弹簧底座62固定在输入轴42上。移动锥盘弹簧61推动移动锥盘2压紧传送带链条34。
在图4中可见，涨紧轮54压紧链条34。
在图3、5中可见，链条34靠移动锥盘弹簧61压紧，就不用涨紧轮54。
在图6中可见，移动锥盘2、固定锥盘33和输出轴31的位置图。
在图7、16、17、18、19中可见，固定摩擦片定位轴46的一半(半圆形)在滑车3中；固定摩擦片定位轴46的另一半(半圆形)在固定摩擦片10中，使固定摩擦片10只能在滑车3中沿着固定摩擦片定位轴46的轴线方向来回滑动，固定摩擦片定位轴46上有豁口对应着活动摩擦片8，使活动摩擦片(链轮)8活动时不至于碰着固定摩擦片定位轴46，活动摩擦片(链轮)8中心的方孔和活动摩擦片一11中心的方孔与中心轴5方形断面形线配合，在没有压紧力时活动摩擦片(链轮)8和活动摩擦片一11只能和中心轴5一起转动。
在图8、11、15中可见，滑车3和滑车滑轨4的位置关系。
在图14中可见，在特例五中，由于滑车滑轨4上，有滚珠59和背面滚珠51，滚珠59和背面滚珠51都是一半在滑车滑轨4中，另一半在锥盘导轨14上的半圆槽中，起到滚珠滑动轴承作用，同时滚珠59和背面滚珠51互为回程滚珠。
在图20、21、22、23中，在特例二中固定摩擦片10伸出2个耳朵与固定摩擦片定位轴46配合。活动摩擦片(链轮)8与固定摩擦片定位轴46有足够的距离，固定摩擦片定位轴46上即使没有豁口，活动摩擦片(链轮)8在活动时也碰不到固定摩擦片定位轴46。
在图24中，轮子28落在凸轮30的分离区50，轮子28被抬起，活动摩擦片(链轮)8、固定摩擦片10和活动摩擦片一11可自由活动；
在图25中，轮子28落在凸轮30的a：啮合区47，轮子28被放下，活动摩擦片(链轮)8、固定摩擦片10、活动摩擦片一11和滑车3被压紧，成为一体。
图26是特例一结构图，在滑车3中，活动摩擦片(链轮)8和固定摩擦片10间隔存在，并省去了活动摩擦片一11。
在特例一中，特例一的运动原理，当轮子28落在凸轮30的a：啮合区47时，压力弹簧26的弹力通过轮子座29、压杆25、压力铰接片二22、压力片16、加压轴13作用在活动摩擦片(链轮)8上，活动摩擦片(链轮)8压紧固定摩擦片10，活动摩擦片(链轮)8中心的方孔与中心轴5方形断面形线配合，固定摩擦片10的半圆豁口与固定摩擦片定位轴46配合，滑车定位轴孔57与固定摩擦片定位轴46配合，固定摩擦片10通过固定摩擦片定位轴46与滑车3配合，固定摩擦片10只能在固定摩擦片定位轴46上滑动，不能转动；当轮子28落在c：分离区50时，轮子28被凸轮30顶起，压力弹簧26的弹力通过轮子28施加在凸轮28上，轮子28带动轮子座31、压杆25、压力铰接片二22、压力片16同时移动，压力片 16脱离加压轴13，松开固定摩擦片10和活动摩擦片(链轮)8，活动摩擦片(链轮)8可以自由转动，与链条34自由搭接。
当加压轴13压紧活动摩擦片(链轮)8和固定摩擦片10时，活动摩擦片(链轮)8、固定摩擦片10、固定摩擦片定位轴46和滑车3固定在一起；当加压轴13松开活动摩擦片(链轮)8和固定摩擦片10时，活动摩擦片(链轮)8和固定摩擦片10脱离，活动摩擦片(链轮)8可以自由转动。链条34上的链条轴轮7可以自由搭接上活动摩擦片(链轮)8。再当轮子28落在凸轮30的a：啮合区47时，链条34与活动摩擦片(链轮)8啮合，即链条34就可以通过活动摩擦片(链轮)8、固定摩擦片10和滑车3与固定锥盘33和移动锥盘2互相传递动力，固定锥盘33和移动锥盘2通过链条34再将动力从输入轴42传给输出轴31。
在图27、28中，看出调速杠杆40的结构。
在图29、30中，特例三，调速杠杆40、滑块36、调速丝母销轴37、限位器销轴62的结构图；
图12、13是加压轴13结构图，加压轴13一端有沟槽，与压力片16配合。
