本实施例中，可以通过改变电流在多个电磁铁的电磁线圈上的流向，改变相应的电磁铁的极性。可以通过改变接入相应电磁线圈的电压的正负极，改变相应的电磁铁的极性。
由于集电器在工作的时候，集电器带电，因此必须对集电器进行密封，防止集电器浸泡在润滑油中。一实施例中，所述转动轴11外套设有第一轴承201，所述第一集电器91设于所述第一轴承201远离连接部12的一侧，且所述第一 集电器91靠近连接部12的一侧设有第一油封401，所述第一油封401套设于所述转动轴11。所述连接轴1通过第一轴承201与变速箱的壳体转动连接，通过所述第一油封401密封变速箱的壳体伸出转动轴11的部位，由于所述第一集电器91完全位于变速箱的壳体的外部，使得第一集电器91隔绝润滑油，防止漏电。

通过设置轴承保证第一转轴5、第二转轴6以及第三转轴104能够相对于变速箱的壳体正常转动，并通过设置油封防止漏油。本实施例中所采用的轴承可以通过轴肩或轴套定位。

上述实施例中的电磁离合器，通过机械结构实现将所述电磁离合器的锁定，结构简单，离合器的加工成本低，节能效果好，换挡平稳，避免相邻两个吸盘之间产生摩擦。采用相应的锁定电磁铁使所述电磁离合器处于一个工作挡位，节省资源。
本实施例还提供了一种变速箱，包括上述的电磁离合器。
如图1和图6所示，所述变速箱还包括变速结构，本实施例中所述变速结构为两级变速结构，所述两级变速结构包括设于第二转轴6远离第二吸盘4的一端且与第二转轴6固定连接的第一齿轮100，与所述第一齿轮100啮合连接的第二齿轮101，沿第二齿轮101的中心轴线设置且贯穿第二齿轮101的第三转轴104，设于所述第三转轴104的第四齿轮103，与第四齿轮103啮合且接于第一转轴5的第三齿轮102。所述第二齿轮101、第四齿轮103与第三转轴104均通过键连接，所述第三齿轮102与第一转轴5通过键连接，所述第一齿轮100与第二转轴6通过键连接。
上述实施例中的齿轮可以采用套筒和轴肩进行定位。
由多个齿轮之间的啮合关系可知，所述电磁离合器处于一挡状态时，第一转轴5将带动第三转轴104和第二转轴6转动，并通过第三转轴104输出，所述电磁离合器处于二挡状态时，第二转轴6将带动第三转轴104和第一转轴5转动，并通过第三转轴104输出，实现变速箱的两级输出。
本实施例中所述变速结构也可以为大于或者等于3级的多级变速结构。
本实施例中所述变速结构为两级变速结构的变速箱具有四个工作挡位，空挡，一挡，二挡以及倒挡，变速结构的工作过程如下。
所述连接轴1转动带动主吸盘2转动，此时所述电磁铁组件300不通电，第一吸盘3和第二吸盘4均不旋转，此时所述变速箱处于空挡状态。
当空挡切换到一挡时，由于第一吸盘3和主吸盘2之间产生不断交替变化的吸引力和排斥力，使得第一吸盘3随着主吸盘2不断旋转，为了保证换挡的平顺性，控制第一电磁铁301的线圈上的电流和第二电磁铁302的线圈上的电流均由小变大逐渐增加，使得第一吸盘3的转速逐渐增加。
当第一吸盘3和主吸盘2的转速相同，且第一吸盘3和主吸盘2之间产生吸引力时，所述第一锁定电磁铁72通电并产生吸引第一定位板712的吸引力，在所述吸引力的作用下，所述第一定位柱711将由第一位置运动至第二位置，第一复位弹簧73被进一步压缩，第一吸盘3相对于主吸盘2固定且二者之间不能够发生相对转动，此时所述电磁离合器保持在一挡工作状态。
在由空挡切换至一挡时，由于需要满足以下两个条件，第一吸盘3和主吸 盘2的转速相同且第一吸盘3和主吸盘2之间产生吸引力，即第一电磁铁301的线圈上的电流和第二电磁铁302的线圈上的电流均达到最大，所述第一锁定组件7才会动作。
满足上述两个条件之前，由于第一电磁铁301和第二电磁铁302之间存在相对转动，即打滑现象，因此第一电磁铁301和第二电磁铁302做切割磁感线运动，会导致第一电磁铁301的线圈和第二电磁铁302的线圈均产生反向电流，因此，可以通过检测第一电磁铁301的线圈和第二电磁铁302的线圈上是否产生反向电流，来判断第一吸盘3和主吸盘2是否出现打滑现象。
因此检测到第一电磁铁301的线圈上的电流和第二电磁铁302的线圈上的电流达到最大或在预设时间内未出现打滑现象，在第一锁定组件7锁止且不需要换挡时，可将第一电磁铁301和第二电磁铁302断电，节省电资源，依靠第一锁定电磁铁72工作时与第一定位板712产生的吸引力，使得所述变速箱保持在一挡工作状态。
当由一挡切换至二挡时，第一电磁铁301和第二电磁铁302通电且控制第一电磁铁301的线圈上的电流和第二电磁铁302的线圈上的电流达到最大。首先改变所述第一锁定电磁铁72的线圈的电流方向，使得第一锁定电磁铁72与第一定位盘71产生排斥力，在所述排斥力和第一复位弹簧73的作用下，所述第一定位柱711快速脱离相应的第一定位孔31，由第二位置恢复至第一位置。
第一电磁铁301、第二电磁铁302和第一锁定电磁铁72断电，第三电磁铁303和第四电磁铁304通电，由于第二吸盘4和主吸盘2之间产生不断交替变化的吸引力和排斥力，使得第二吸盘4随着主吸盘2不断旋转，为了保证换挡的平顺性，控制第三电磁铁303的线圈上的电流和第四电磁铁304的线圈上的电流均由小变大逐渐增加，使得第二吸盘4的转速逐渐增加。
当第二吸盘4和主吸盘2的转速相同，且第二吸盘4和主吸盘2之间产生吸引力时，第二锁定电磁铁82通电并产生吸引第二定位板812的吸引力，在所述吸引力的作用下，所述第二定位柱811将由第三位置运动至第四位置，第二吸盘4相对于主吸盘2固定且二者之间不能够发生相对转动，此时所述变速箱保持在二挡工作状态。
在由一挡切换至二挡时，由于需要满足以下两个条件，第二吸盘4和主吸 盘2的转速相同且第二吸盘4和主吸盘2之间产生吸引力，即第三电磁铁303的线圈上的电流和第四电磁铁304的线圈上的电流均达到最大，所述第二锁定组件8才会动作。
满足上述两个条件之前，由于第三电磁铁303和第四电磁铁304之间存在相对转动，即打滑现象，因此第三电磁铁303和第四电磁铁304做切割磁感线运动，会导致第三电磁铁303的线圈和第四电磁铁304的线圈均产生反向电流，因此，可以通过检测第三电磁铁303的线圈和第四电磁铁304的线圈上是否产生反向电流，来判断第二吸盘4和主吸盘2是否出现打滑现象。因此检测到第三电磁铁303的线圈上的电流和第四电磁铁304的线圈上的电流达到最大或在预设时间内未出现打滑现象，在第二锁定组件8锁止且不需要换挡时，可将第三电磁铁303和第四电磁铁304断电，节省电资源，依靠第二锁定电磁铁82工作时与第二定位柱811产生的吸引力，使得所述变速箱保持在二挡工作状态。
上述由一挡切换至二挡的过程，可适用于缓慢换挡的情况。如果是碰到突然急加速的情况，相应的第一电磁铁301的线圈上的电流和第二电磁铁302的线圈上的电流突然增至最大，以快速的满足换挡条件进行换挡，其他过程与上述由一挡切换至二挡的过程相同。
为了节省电资源，在变速箱保持在一挡工作状态之后，可以将第一电磁铁301和第二电磁铁302断电，通过第一锁定电磁铁72使得第一吸盘3相对于主吸盘2固定且二者之间不能够发生相对转动。在电磁离合器保持在二挡工作状态之后，可以将第三电磁铁303和第四电磁铁304断电，通过第二锁定电磁铁82使得第二吸盘4相对于主吸盘2固定且二者之间不能够发生相对转动。
根据变速箱的工作过程可知，所述第一电磁铁301和第二电磁铁302处于通电状态时，所述第一吸盘3带动所述第一转轴5转动，此时由第一转轴5带动第三转轴104和第二转轴6转动。为了避免造成第一转轴5和第二转轴6发生运动干涉，需要要求所述第三电磁铁303和第四电磁铁304处于断电状态。
相应的，当第三电磁铁303和第四电磁铁304处于通电状态时，第一电磁铁301和第二电磁铁302处于断电状态。
在产生反向电流时，可通过润滑油为相应电磁铁的线圈降温，保证相应的电磁铁能够正常工作。
倒挡与一挡所采用的结构相同，只需改变驱动结构驱动连接轴1的转动方向，使连接轴1的转动方向与一挡时连接轴1的转动方向相反即可。
本实施例所述的采用两级变速结构的变速箱应用于电动车时，电机作为所述变速箱的驱动装置，由于电动车在不行驶时电机就不转动，电动车通电后即可将通过第一定位盘71将第一吸盘3和主吸盘2锁定，即挂一挡。由于本实施例通过机械结构使得第一吸盘3和主吸盘2锁定，因此所述变速箱能够承受更大的扭力，更有利于电动车的起步以及加速，而传统的液压变速箱为摩擦片式的锁定方式，存在打滑的风险，不利于电动车的急加速。
本实施例通过控制多个电磁铁的体积和吸盘的直径，可以实现扭力输出承受值的变化。
上述实施例所述变速箱可以应用于燃油汽车，未连接于燃油汽车的发动机的液压泵，可以提升燃油汽车的动力性和燃油经济性，降低车辆成本和车身重量。
燃油汽车在怠速时，由于所述电磁离合器处于空转状态，第二电磁铁302和第三电磁铁303将会相对于第一吸盘3的第一电磁铁301和第二吸盘4的第四电磁铁304发生相对转动，第一电磁铁301的线圈和第四电磁铁304的线圈将会产生电压，可以通过对所述电压进行回收存储能量。
在所述主吸盘2转动的过程中，将第二电磁铁302和第一电磁铁301也通电，若通过改变电流的流向不断的改变第一电磁铁302或第一电磁铁301的极性，使得第一转轴5的转速不断增加，此时第一转轴5作为输出轴，本实施例所述电磁离合器可以作为直流电机使用。
在所述主吸盘2转动的过程中，将第三电磁铁303和第四电磁铁304通电，若通过改变电流的流向不断的改变第三电磁铁303或第四电磁铁304的极性，使得第二转轴6的转速不断增加，此时第二转轴6作为输出轴，本实施例所述电磁离合器可以作为直流电机使用。
汽车在运转时，无论是以一挡还是二挡进行工作，第一吸盘3和第二吸盘4中始终有一个与主吸盘2存在转速差，由于转速差的存在，有切割磁感线运动，因此可以利用这个转速来发电。
上述实施例中的变速箱还可以应用于混合动力汽车。

可选的，所述第二锁定组件8包括能够沿主吸盘2的径向往复运动于第三位置和第四位置的第二定位件820，驱动所述第二定位件820往复运动的第二定位电磁铁840，以及驱动所述第二定位件820运动并使所述第二定位件820置于所述第三位置的第二定位弹簧830，其中，所述第二定位件820远离所述第二吸盘4的一端为永磁体，且所述第二定位件820置于所述第三位置时，所述第二定位弹簧830处于压缩状态，此时，第二定位弹簧830的压缩量较小。
一实施例中，如图7所示，所述连接圆筒120的外壁上设有第二安装槽1203，所述第二安装槽1203上贯穿设有第三贯穿孔。所述第二定位件820可以包括由永磁体制成的第二定位板件8201，及连接于第二定位板件8201指向第二吸盘4所在侧的第二定位块8202，所述第二吸盘4上沿其周向设有至少一个与所述第二定位块8202相适配的第二定位槽410。其中，所述第二定位板件8201为永磁体。
可选的，所述第二定位弹簧830设有两个且分布于所述第二定位块8202两侧，并夹设于所述第二定位板件8201和第二定位电磁铁840之间。所述第二定位件820远离第二定位电磁铁840的一侧设有第二挡板810，通过所述第二挡板810将第二定位件820、第二定位电磁铁840安装于所述第二定位槽410内。所述第二定位电磁铁840上与第二定位块8202对应的位置设有第四贯穿孔，所述第三贯穿孔和第四贯穿孔对应设置。

所述第二吸盘4和主吸盘2之间相互锁定以及解锁的过程如下。
所述第三电磁铁303和第四电磁铁304通电后，在所述第二吸盘4与主吸盘2无相对转动时，所述第二定位电磁铁840通电并产生吸引第二定位板件8201的力，在所述吸引力的作用下第二定位板件8201将带动所述第二定位块8202向第二吸盘4运动，使得第二定位块8202依次贯穿所述第四贯穿孔，第三贯穿孔并插入第二吸盘4上相应的第二定位槽410内。在该过程中所述第二定位弹簧830被继续的压缩，使得第二吸盘4锁定主吸盘2。改变所述第二定位电磁铁 840的线圈上的电流方向，使得所述第二定位电磁铁840产生排斥第二定位板件8201的排斥力，在所述排斥力以及第二定位弹簧830的作用下，第二定位块8202脱离第二定位槽410，并置于所述第三贯穿孔内，且所述所述第二定位板件8201抵压于所述第二挡板810，使得第二吸盘4能够相对于主吸盘2转动，实现第二吸盘4和主吸盘2之间的解锁。
一实施例中，所述第一定位槽310的个数是所述第一锁定组件7的个数的倍数，所述第二定位槽410的个数是所述第二锁定组件8的个数的倍数，而且，所述第一锁定组件7的个数等于所述第二锁定组件8的个数。可选的，所述第一锁定组件7和第二锁定组件8均设有两个，而且两个第一锁定组件7、两个第二锁定组件8分别沿所述连接圆筒120的周向对称分布。

为了动平衡，所述第一锁定组件7和第二锁定组件8对称分布。可选的，每个所述第一定位槽310和与其相邻的两个所述第一电磁铁301之间的夹角，与每个所述第二定位槽410和与其相邻的两个所述第四电磁铁304之间的夹角一致。
实施例三
本实施例以实施例二为基础。
如图8和图9所示，为了保证第一吸盘3、第二吸盘4分别能够相对于主吸盘1自由转动，且能够承受大的吸引力而不易发生变形，可以在所述第一吸盘3和主吸盘2之间以及第二吸盘4和主吸盘2之间分别安装有一个推力轴承。
可选的，所述主吸盘2与第一吸盘3相对的一侧设有第一滑槽210，所述第一吸盘3与主吸盘2相对的一侧与第一滑槽210对应的位置设有第三滑槽320，所述第一吸盘3和主吸盘2之间设有夹设于第一滑槽210和第三滑槽320之间的第一滚动体500，所述第一滑槽210、第一滚动体500以及第三滑槽320形成第一推力轴承。
所述主吸盘2与第二吸盘4相对的一侧设有第二滑槽220，所述第二吸盘4与主吸盘2相对一侧与第二滑槽220对应的位置设有第四滑槽420，所述第二吸盘4与主吸盘2之间设有夹设于第二滑槽220和第四滑槽420之间的第二滚动体600，所述第二滑槽220、第二滚动体600以及第四滑槽420形成第二推力轴承。
通过设置第一滚动体500和第二滚动体600，使得第一吸盘3和主吸盘2相对的端面之间设有间隙，所述第二吸盘4和主吸盘2相对的端面之间也设有间隙。在第一吸盘3和主吸盘2以及第二吸盘4和主吸盘2发生相对转动时，第一吸盘3和主吸盘2相对的端面之间以及第二吸盘4和主吸盘2相对的端面之间不会发生摩擦。
本实施例所述的第一滚动体500以及第二滚动体600是推力轴承中的滚珠部分。实施例一所述电磁离合器也可以设置上述实施例中的第一滚动体和第二滚动体，滚动体的安装位置可以与上述实施例中第一滚动体和第二滚动体的安装位置相同。
