Differential mechanism and vehicle

The invention relates to the technical field of differential mechanisms, and provides a differential mechanism and a vehicle. The differential mechanism comprises a planet shaft, a first transmission shaft and a second transmission shaft; the planetary gear is rotationally connected with the planetary shaft through a rolling piece; at least one first oil outlet hole is further formed in the position, connected with the rolling piece, of the planet shaft, and the first oil outlet hole is communicated with the cavity. According to the technical scheme, active lubrication can be provided for parts in the differential mechanism, so that the problem of ablation of the parts in the differential mechanism is solved. 本申请涉及差速器技术领域，提供一种差速器及车辆，其中，差速器包括：行星轴，行星轴内设有用于导油的腔室；行星齿轮，通过滚动件与行星轴转动连接；其中，行星轴与滚动件连接的位置还设有至少一个第一出油孔，第一出油孔与腔室相连通。通过本申请的技术方案，能够对差速器内的零部件提供主动润滑，以减少差速器内的零部件的烧蚀问题。
