具体实施方式：
下面结合附图对本发明在有一组变速齿的基础上增加一组变速齿使原本一个挡位增加到三个挡位基本原理的详细说明：
如图一所示，本发明行星齿式三离合变速器由离合器部分1、差速器部分2和变速齿部分3组成。
如图所示，动力输入轴4设置于离合器主动盘5中间为一体，离合器主动盘5上分别设有离合器从动盘(一)7、离合器从动盘(二)8和离合器从动盘(三)9，所述太阳齿传动轴14一端设有离合器从动盘(2)为一体，所述太阳齿13中间设有太阳齿传动轴14为一体，所述太阳齿传动轴14另一端设有一挡主动齿16，所述一挡主动齿16上设有一挡从动齿17并互相啮合，所述太阳齿13周围设有行星齿轮11并互相啮合，所述行星齿轮11中间设有行星齿轮轴12，所述行星齿轮轴12一侧设有行星齿架6为一体，所述行星齿架6上设有离合器从动盘(二)8为一体，所述行星齿轮11外围设有行星齿圈10并互相啮合，所述行星齿圈10上设有离合器从动盘(三)9为一体，所述行星齿圈10一端设有行星齿圈传动轴15为一体，所述行星齿圈传动轴15一端设有三挡主动齿18为一体，所述三挡主动齿18上设有三挡从动齿19并互相啮合，所述一挡从动齿17与三挡从动齿19中间设有动力输出轴20为一体。
本发明行星齿式三离合变速器工作原理如下：
当离合器从动盘(一)7、离合器从动盘(二)8、离合器从动盘(三)9都与离合器主动盘5分离时，动力从动力输入轴4输入，进一步动力传递到离合器主动盘5，离合器主动盘5空转，不向外传输动力，本发明行星齿式三离合变速器为空挡。
当离合器主动盘5与离合器从动盘(二)8结合，离合器主动盘5与离合器从动盘(一)7分离，离合器主动5与离合器从动盘(三)9分离，此时动力由动力输入轴4传输到离合器主动盘5，进一步的离合器主动盘5通过结合的离合器从动盘(二)8将动力传输到太阳齿传动轴14，进一步的太阳齿传动轴14将动力传输到一挡主动齿16，进一步的一挡主动齿16将动力传输到互相啮合的一挡从动齿17，进一步的一挡从动齿17将动力传输到动力输出轴20并向外输出动力，此时的速比是一挡主动齿16与一挡从动齿17的速比，本发明行星齿式三离合变速器一挡完成。
当离合器主动盘5与离合器从动(二)8分离，离合器主动盘5与离合器从动盘(三)9分离，离合器主动盘5与离合器从动盘(一)7结合，此时动力由动力输入轴4传输到离合器主动盘5，进一步的离合器主动5通过结合的离合器从动盘(一)7将动力传输到行星齿架6，进一步的行星齿架6通过行星齿 轮轴12将动力传输到行星齿轮11，进一步的行星齿轮11将动力同时传输到行星齿圈10和太阳齿13，此时行星齿圈10和太阳齿13会与行星齿架6同方向运转，进一步的行星齿圈10和太阳齿13同时将动力传输到行星齿圈传动轴15和太阳齿传动轴14，进一步的行星齿圈传动轴15和太阳齿传动轴14同时将动力传输到三挡主动齿18和一挡主动齿16，进一步的三挡主动齿18和一挡主动齿16同时将动力传输到互相啮合的三挡从动齿19和一挡从动齿17，进一步的三挡从动齿19与一挡从动齿17同时将动力传输到动力输出轴20并向外输出动力，由于一挡主动齿16与三挡主动齿18转速不同存在转速差，太阳齿传动轴14与行星齿圈传动轴15也会有转速差，进一步的太阳齿13与行星齿圈10也会有转速差，太阳齿13与行星齿圈10的转速差由行星齿轮11来弥补均衡，此时的速比是一挡主动齿16和三挡主动齿18的平均值，本发明行星齿式三离合变速器升为二挡。
当离合器主动盘5与离合器从动盘(一)7分离，离合器主动盘5与离合器从动盘(二)8分离，离合器主动盘5与离合器从动盘(三)9结合，此时动力由动力输入轴4传输到离合器主动盘5，进一步的离合器主动盘5通过结合的离合器从动盘(三)9将动力传输到行星齿圈10，进一步的行星齿圈10将动力传输到行星齿圈传动轴15，进一步的行星齿圈传动轴15将动力传输到三挡主动齿18，进一步的三挡主动齿18将动力传输到互相啮合的三挡从动齿19，进一步的三挡从动齿19将动力传输到动力输出轴20并向外输出动力，此时的速比是三挡主动齿18与三挡从动齿19的速比，本发明行星齿式三离合变速器挡位升为三挡。
