The invention provides a two-gear gearbox integrated with a differential mechanism. The two-gear gearbox comprises a differential coupling module, a power input gear shaft (8), a power conversion gear shaft (9), a clutch (12), a brake (13), a lower box body (10), an upper box body (11), a planet carrier bearing (31), a power input gear shaft bearing (32) and a power conversion gear shaft bearing (33). The two-gear gearbox integrated with the differential mechanism has the beneficial effects that through ingenious design, a speed change device and a differential speed output device are integrated, so that the structure is compact, the weight is light, and the cost is low; speed change of motion input by a motor can be achieved, the motion subjected to speed change can be output to a transmission shaft in a differential speed mode, and finally a vehicle is driven to run efficiently; and the two-gear gearbox is particularly suitable for being used as a gearbox of a pure electric vehicle or a hybrid electric vehicle, and is also suitable for an internal combustion engine or other vehicles in any power form.

    本发明提供一种集成差速器的两档变速箱,包括:差动耦合模块,动力输入齿轮轴(8),动力转换齿轮轴(9),离合器(12),制动器(13),下箱体(10),上箱体(11),行星架轴承(31),动力输入齿轮轴轴承(32),动力转换齿轮轴轴承(33);本发明的有益效果为:通过巧妙的设计,将变速装置和差速输出装置集成为一体,结构紧凑,重量轻,成本低,既能够对电动机输入的运动实现变速,又能够将变速后的运动差速输出至传动轴并最终驱动车辆高效行驶,尤其适合作为纯电动汽车或混合动力汽车的变速箱,也适用于内燃机或其它任何动力形式的车辆。
