The invention discloses a planet wheel type differential mechanism, a power transmission system and a vehicle, the planet wheel type differential mechanism comprises a planet mounting seat, a planet wheel structure and an output shaft structure, and the planet mounting seat is used for external power input; the planet wheel structure comprises a long planet wheel and a short planet wheel which are rotationally arranged on the planet mounting base along the axis where the first direction is located, the long planet wheel is provided with a first meshing section and a second meshing section, and the short planet wheel is meshed with the first meshing section and arranged in the circumferential direction of the planet mounting base; the output shaft structure comprises a left half shaft and a right half shaft which extend in the first direction and are oppositely arranged, a first sun gear is arranged on the left half shaft, a second sun gear is arranged on the right half shaft, the short planet gear is meshed with the first sun gear, and the second meshing section is meshed with the second sun gear. When the left half shaft and the right half shaft have rotation difference in the output process, the long planet wheel and the short planet wheel rotate relatively, power transfer is achieved, and meanwhile the axial size of the differential mechanism structure is greatly reduced.

    本发明公开一种行星轮式差速器、动力传动系统及车辆,行星轮式差速器包括行星安装座、行星轮结构及输出轴结构,行星安装座用以供外部动力输入;行星轮结构包括沿第一方向所处轴线转动设置于行星安装座的长行星轮与短行星轮,长行星轮具有第一啮合段和第二啮合段,短行星轮与第一啮合段啮合设置,且沿行星安装座的周向方向排布;以及,输出轴结构包括沿第一方向延伸且相对设置的左半轴及右半轴,左半轴上设置有第一太阳轮,右半轴上设有第二太阳轮,短行星轮啮合至第一太阳轮,第二啮合段啮合在第二太阳轮。当左右半轴在输出过程中出现转动差时,长短行星轮之间发生相对转动,实现功率转移,同时差速器结构轴向尺寸大大缩小。
