Description

离合器液力变矩调节装置 技术领域
本发明涉及一种汽车配件领域，特别是涉及一种可调节动力传输扭矩和转速的离合器液力变矩调节装置。
背景技术
传统变速箱在换挡过程中，离合器主动盘和丛动盘承受扭矩和转速变化过程中缓冲和动力衔接，对离合器的主动盘和丛动盘使用寿命影响很大，离合器的主动盘和丛动盘寿命短和换挡冲击直接影响双离合变速箱和电动汽车两挡变速箱的发展和使用。
发明内容
本发明的目的是弥补现有技术的不足，提供一种结构简单、操作简便、可精准控制在动力传输中的扭矩变化和转速差，从而可有效消除离合器冲击与摩擦的离合器液力变矩调节装置。
为了实现上述目的本发明采用的技术方案如下：
本发明离合器液力变矩调节装置主要由动力输入轴、设置于动力输入轴上的主动盘和从动盘、与动力输入轴相对应设有的动力输出轴构成，其中，所述动力输入轴的一端设有太阳齿轮，所述太阳齿轮设置于紧靠着从动盘设有的壳体中央，所述太阳齿轮上啮合有至少一个行星齿轮，所述行星齿轮的中央分别设有行星齿轮轴，所述行星齿轮轴固定在所述壳体的内侧，在所述壳体内所述太阳齿轮和行星齿轮相啮合的一侧形成有高压油腔，另一侧形成有低压油腔，所述低压油腔上连接有低压油腔进油管，所述高压油腔上连接有高压油腔出油管，所述高压油腔出油管上设有阀门。
所述太阳齿轮与所述动力输入轴成一体，壳体一侧与从动盘连接，壳体另一侧与输出轴为一体。
本发明离合器液力变矩调节装置的有益效果是：由于通过高压油腔和低压油腔内的油压来调节动力传输扭矩和转速，因此，完全可以消除离合器工作时的冲击与磨损，离合器的主动盘与从动盘只起到动力输出过程中的锁止作用。本发明离合器液力变矩调节装置还具有结构简单，操作简便、成本低、效果良好、使用寿命长等优点。
附图说明
图1是本发明离合器液力变矩调节装置的结构示意图；
图2是图1的A-A剖面图。
图中：1、壳体；2、太阳齿轮；3、行星齿轮；4、行星齿轮轴；5、低压油腔；6、高压油腔；7、低压油腔进油管；8、高压油腔出油管；9、从动盘；10、主动盘；11、阀门；12、动力输入轴；13、动力输出轴。
具体实施方式
下面结合附图对本发明进行详细说明。
如图1、图2所示，本发明离合器液力变矩调节装置主要由动力输入轴12、设置于动力输入轴12上的主动盘10和从动盘9、与动力输入轴12相对应设有的动力输出轴13构成，其中，所述动力输入轴12的一端设有太阳齿轮2，所述太阳齿轮2与所述动力输入轴12成一体，所述太阳齿轮2设置于紧靠着从动盘9设有的壳体1中央，所述太阳齿轮2上啮合有至少一个行星齿轮3，所述行星齿轮3的中央分别设有行星齿轮轴4，所述行星齿轮轴4固定在所述壳体1内侧，在所述壳体1内，所述太阳齿轮2和行星齿轮3相咬合的一侧形成有高压油腔6，另一侧形成有低压油腔5，所述低压油腔5上设有低压油腔进油管7，所述高压油腔6上设有高压油腔出油管8，所述高压油腔出油管8上设有阀门11，所述动力输出轴13与所述壳体1成一体。
本发明离合器液力变矩调节装置的工作原理如下：
当主动盘10与从动盘9分离时，动力输入轴12带动太阳齿轮2旋转，太阳齿轮2进而带动行星齿轮3旋转，从而将液力油通过低压油腔进油管7吸入到低压油腔5内，当太阳齿轮2和行星齿轮3相啮合旋转时，液力油通过太阳齿轮2和行星齿轮3的齿与齿间的缝隙排挤到高压油腔6内，排挤到高压油腔6的液力油通过高压油腔出油管8和阀门11向外排出，此时，所述壳体1与与壳体1成一体的动力输出轴13不随动力输入轴12一起转动。
当阀门11缓慢关闭时，所述高压油腔8内的液力油排出受到阻力，高压油腔6内的液力油压升高，而对行星齿轮3和太阳齿轮2之间产生反作用力，此时，所述行星齿轮轴4带动壳体1随同动力输入轴12同方向一起旋转，所述壳体1带动所述动力输出轴13向外输出动力，所述阀门11关闭的越小，高压油腔6内的油压越大，液压油对行星齿轮3和太阳齿轮2的反作用力也就越大，通过行星齿轮轴4对外壳1的扭矩力越大，动力输出轴13的扭矩力就越大。
当阀门11完全关闭时，所述高压油腔出油管8内的液力油完全停止流动，所述高压油腔6内的液力油不可压缩，迫使行星齿轮3围绕太阳齿轮2同方向转动，此时，动力输入轴12与动力输出轴13转速和扭矩基本相同，从动盘9与主动盘10通过离合器原理锁止为一体，使动力输入轴12通过锁止在一起的主动盘10和从动盘9与壳体1为刚性连接，通过 动力输出轴13直接向外输出动力，阀门11打开，高压油腔6内的液力油压下降，为下一个工作周期做准备，离合器液力变矩调节装置完成一个工作周期。
