半轴（Driver Shaft）也叫驱动轴（CVJ,CV joint,constant velocity joint）是将差速器与驱动轮连接起来的轴。半轴是变速箱减速器与驱动轮之间传递扭矩的轴，其内外端各有一个万向节（U/JOINT)分别通过万向节上的花键与减速器齿轮及轮毂轴承内圈连接。

In this research a kind of half axle gear was introduced, whose model was made by the CAD technology. The forming process of the half axle gear was simulated by FEM software.
本课题以半轴齿轮为例，先利用模具CAD技术对半轴齿轮进行三维实体建模，然后应用FEM模拟技术等对半轴齿轮的成形过程进行数值模拟仿真。

行星齿轮压着半轴齿轮，则半轴齿轮转动。
The differential pinions press against the side gears, and the side gears rotate.
由于半轴通过花键与半轴齿轮连接，从而半轴也转动。
Since the axle shafts are splined to the side gears the shafts lso rotate.
这样外侧车轮轴上的半轴齿轮比内侧车轮轴上的半轴齿轮转动更快。
Thus, the side gear on the outer-wheel axle turns more rapidly than the side gear on the inner-wheel axle.
