Description

一种外置控制的无级变速装置
技术领域
本发明涉及一种外置控制的无级变速装置，属于无级变速器领域。
背景技术
现代汽车上较广泛使用的无级变速器，多是通过改变主动轮与从动轮的有效半径的大小来实现连续的速比变化。如CVT，但限于材料与结构的原因，目前多数无级变速器无法在车用的大功率传动中应用。
发明内容
有鉴于此，本发明的目的是提供一种传递功率大，可连续变化速比的的外置控制的无级变速装置，通过控制摩擦力的大小实现速比变化的无级控制。
本发明采用以下方案实现：一种外置控制的无级变速装置，包括变速箱体和设于变速箱体上的输入轴和输出轴，还包括设于变速箱体内的行星轮系，所述行星轮系的太阳轮固连于所述输入轴上，所述行星轮系的行星架的动力输出端与所述输出轴固连，所述行星架的与所述行星轮系的行星轮相配合连接的动力输入端向外延伸并可与输入轴实现分离或接合传动；还包括套设于输出轴上并与所述行星轮系的内齿圈固连的外引盘以及对外引盘实施制动的制动器。
进一步的，所述输入轴上设置有与行星架的动力输入端延伸部实现分离和接合传动的离合器。
进一步的，所述离合器为牙嵌式离合器，并由气缸通过拨叉驱动其与行星架的离合。
与现有技术相比，本发明具有以下有益效果：该外置控制的无级变速装置设计合理，通过控制摩擦力的大小实现输出转速的无级控制，速比变化连续，控制单元结构简单，造价低，同时控制单元外置，安装和后期维修方便。
附图说明
图1是本发明实施例构造示意图；
图中标号说明：1-变速箱体、2-输入轴、3-输出轴、4-太阳轮、5-行星架、6-行星轮、7-内齿圈、8-外引盘、9-制动器、10-离合器、11-气缸、12-拨叉。
具体实施方式
为使本发明的目的、技术方案及优点更加清楚明白，以下将通过具体实施例和相关附图，对本发明作进一步详细说明。
如图1所示，一种外置控制的无级变速装置，包括变速箱体1和设于变速箱体1上的输入轴2和输出轴3，还包括设于变速箱体1内的行星轮系，所述行星轮系的太阳轮4固连于所述输入轴2上，并且该行星轮系中的太阳轮4、行星架5和内齿圈7均是绕同一轴线回转，所述行星轮系的行星架5的动力输出端与所述输出轴2固连，所述行星架5的与行星轮6相配合连接的动力输入端向外延伸并可与输入轴2实现分离和接合传动；还包括套设于输出轴3上并与所述行星轮系的内齿圈7固连的外引盘8以及对外引盘8实施制动控制的外置制动器9，该外引盘8与内齿圈7同步转动，通过制动器9控制外引盘8的转速便控制了内齿圈7的转速。
在本实施例中，所述输入轴2上设置有通过轴向滑移与行星架5的动力输入端延伸部实现分离和接合传动的离合器10。
在本实施例中，所述离合器10为牙嵌式离合器，并由气缸11通过拨叉12驱动其与行星架5的分离或接合。
该一种外置控制的无级变速装置的工作原理：（1）高速档：制动器9松开，气缸右移，驱动拨叉12带动离合器10将输入轴2和行星架5接合，此时i1H=n1/nH=1，即n1= nH，且n3=nH。
（2）低速档：气缸左移，驱动拨叉12带动离合器10将输入轴2和行星架5分离，同时制动器9对内齿圈制动使其刹紧（n3=0），此时i1H=n1/nH=1+z3/z1（z3、z1分别为内齿圈7和太阳轮4的齿数），此时nH=n1/(1+z3/z1)，i1H>1，所以为低速档。
（3）无级变速档：在制动器9制动过程中，可以控制内齿圈的转速从n3=n1下降到n3=0，在此过程中，行星架6的转速nH=，因此，当内齿圈的转速从n1下降至0时，行星架的转速nH则会连续地从n1下降到n1/(1+z3/z1)，从而通过控制外引盘的转速实现行星架的无级变速。
上列较佳实施例，对本发明的目的、技术方案和优点进行了进一步详细说明，所应理解的是，以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
