Provided is a differential comprising: an input gear (5) capable of receiving torque from outside the differential; a planet gear shaft (2) which extends along a radial direction (R) of the input gear (5) and is directly drivingly coupled to the input gear (5); a planetary gear (3) attached to the planetary gear shaft (2) and capable of rotating around the planetary gear shaft (2); and an output gear (4) that meshes with the planetary gear (3) and can transmit torque to the outside of the differential. Therefore, the problems of overlarge geometric dimension and heavy weight of the shell caused by the fact that torque transmission needs to pass through the shell of the differential mechanism are solved, the number of bolts used for fixing the input gear and the shell is reduced, the corresponding cost is reduced, and the installation problem of the bolts is eliminated.

    提供一种差速器,包括:输入齿轮(5),其能够接收来自差速器的外部的扭矩;行星轮轴(2),其沿着输入齿轮(5)的一个径向(R)延伸且与输入齿轮(5)直接传动联接;行星齿轮(3),其安装于行星轮轴(2),并且能够绕着行星轮轴(2)转动;以及输出齿轮(4),其与行星齿轮(3)啮合,能够向差速器的外部传递扭矩。这样,避免了由于扭矩传递需要经过差速器的壳体导致该壳体几何尺寸过大且重量较重的问题,减少用于输入齿轮和壳体之间固定的螺栓的数量,降低相应的成本以及消除螺栓的安装问题。
