The invention provides a hybrid power gearbox. The hybrid power gearbox comprises a first motor; a second motor; a transmission mechanism which comprises an input shaft, a front transmission gear set, a speed change mechanism and transmission gear sets of the two motors; a first housing, a second housing and a third housing; the first shell comprises a clutch chamber and a motor part, the motor part comprises a first hole, a second hole and a third hole, the input shaft is arranged in the first hole in a penetrating manner, and stators of the two motors are respectively arranged in the second hole and the third hole; a middle wall plate is arranged in an inner cavity of the second shell, a front transmission gear set and transmission gear sets of the two motors are arranged in a cavity defined by the middle wall plate and the first shell, and a speed change mechanism is arranged in a cavity defined by the middle wall plate and the third shell. Due to the fact that the two motors are arranged on the first shell, factory inspection can be carried out after assembly is completed, a speed change mechanism can be assembled in the cavity defined by the second shell and the third shell in advance by a speed change box factory, and therefore the hybrid power speed change box which is beneficial to assembly and low in cost is obtained.

    本发明提供一种混合动力变速箱,包括:第一电机;第二电机;传动机构,包括输入轴、前传动齿轮组、变速机构、两个电机的传动齿轮组;第一壳体、第二壳体和第三壳体;第一壳体包括离合器室和电机部,电机部包括第一孔、第二孔和第三孔,输入轴穿设在第一孔中,两个电机的定子分别安设在第二孔和第三孔中;第二壳体的内腔里设置有中间壁板,中间壁板与第一壳体围成的空腔里安设前传动齿轮组和两个电机的传动齿轮组,中间壁板与第三壳体围成的空腔里安设变速机构。由于两个电机安设在第一壳体上,可装配完成进行出厂检测,且变速箱厂可提前将变速机构装配在第二壳体和第三壳体围成的空腔里,从而得到一种利于装配且成本较低的混合动力变速箱。
