The invention relates to a new energy vehicle driving shaft and hub connecting structure. The connecting structure comprises a hub, a universal joint shell and a spline adapter arranged between the hub and the universal joint shell, wherein an inner end of the spline adapter is inserted into the hub, an outer end of the spline adapter is exposed out of the hub, a first spline matching part is arranged between an inner end of the spline adapter and the hub, a second spline matching part is arranged between an outer end of the spline adapter and the universal joint shell, and the number of spline teeth of the second spline matching part is larger than that of spline teeth of the first spline matching part. Compared with the prior art, by adding the spline switching structure, an original spline assembling part is moved out of a space limited area, then a purpose of increasing the tooth number of the driving shaft and the hub spline of the new energy vehicle is achieved, spline extrusion stress and abrasion are reduced, abnormal sound faults are reduced, and the use experience is improved.

    本发明涉及一种新能源车驱动轴与轮毂连接结构,包括轮毂、万向节壳体以及设置在轮毂与万向节壳体之间的花键转接件,该花键转接件的内端插设在轮毂内,外端外露出轮毂,花键转接件的内端与轮毂之间设有第一花键配合部,花键转接件的外端与万向节壳体之间设有第二花键配合部,并且第二花键配合部的花键齿数大于第一花键配合部的花键齿数。与现有技术相比,本发明通过增加花键转接结构,将原有的花键装配部分外移出空间受限区域,进而实现增加新能源车驱动轴与轮毂花键齿数的目的,减少了花键挤压应力与磨损,降低受异响故障,提高了使用体验。
