The invention relates to a vehicle, a wheel-side power system and a wheel-side speed reducer. The wheel-side speed reducer comprises a speed reducer shell, and a power input shaft, an intermediate shaft and a final-stage gear shaft are arranged on the speed reducer shell. The wheel-side speed reducer further comprises a planet row, one of a sun gear, a planet carrier and a gear ring in the planetrow is fixed to the speed reducer shell, and the other two of the sun gear, the planet carrier and the gear ring serve as an input component and an output component respectively and are used for achieving reduction transmission. The input component of the planet row is a sun gear, the sun gear is in transmission connection with the final-stage gear shaft, and speed reduction transmission is formedbetween the middle shaft and the final-stage gear shaft through a fixed shaft gear. Or the input component of the planet row is a gear ring, outer teeth are arranged on the gear ring, and the gear ring is meshed with an middle shaft output gear arranged on the middle shaft through the outer teeth; a planet row output shaft is connected to an output component of the planet row and forms a power output shaft of the speed reducer. According to the scheme, the problem that the axial space between an existing speed reducer and a wheel is limited is solved.

本发明涉及车辆、轮边动力系统及轮边减速器。其中轮边减速器包括减速器壳体，减速器壳体上设有动力输入轴、中间轴和末级齿轮轴；轮边减速器还包括行星排，行星排中的太阳轮、行星架和齿圈的其中一个固定在减速器壳体上，另外两个分别作为输入构件和输出构件，用于实现减速传动；行星排的输入构件为太阳轮，太阳轮与末级齿轮轴传动连接，中间轴与末级齿轮轴之间通过定轴齿轮形成减速传动；或者，行星排的输入构件为齿圈，齿圈上设有外齿，齿圈通过外齿与中间轴上设置的中间轴输出齿轮啮合；行星排的输出构件上连接有行星排输出轴，行星排输出轴构成减速器的动力输出轴。上述方案解决了现有的减速器与车轮之间的轴向空间有限的问题。
