The invention provides a gearbox for engineering machinery and a working method of the gearbox. The gearbox structurally comprises an engine power input shaft. A first locking mechanism; a planet wheel; a planet carrier; a sun gear; a first motor EMI; the first motor EMI outputs power to a gear A; a power output gear B of the first motor EMI; an inner gear ring; an outer ring gear; a PTO gear; a PTO synchronizer; a second motor EMII; the second motor EMII is a power output gear; a second locking mechanism; a second planetary mechanism sun gear; a second planetary mechanism planet wheel; a second planetary mechanism planet carrier; a second planetary mechanism inner gear ring; and a power output shaft. The locking mechanism and the planet row power dividing mechanism are combined for use, so that multiple working modes can be realized; the two-gear planet row is added in the structure, a wide speed ratio range can be provided, the dynamic property is high, and more energy is saved and efficiency is higher.

    本发明提供了一种工程机械用变速箱及其工作方法,变速箱结构包括发动机动力输入轴;第一锁止机构;行星轮;行星架;太阳轮;第一电机EMⅠ;第一电机EMⅠ动力输出齿轮A;第一电机EMⅠ动力输出齿轮B;内齿圈;外齿圈;PTO齿轮;PTO同步器;第二电机EMⅡ;第二电机EMⅡ动力输出齿轮;第二锁止机构;第二行星机构太阳轮;第二行星机构行星轮;第二行星机构行星架;第二行星机构内齿圈;动力输出轴。锁止机构与行星排功率分流机构组合使用,可以实现多种工作模式;构型中加入两挡行星排,可提供较宽的速比范围,动力性强,更加节能高效。
