中文摘要：

提出了一种非圆行星差速器概念模型,将其应用于越野汽车分动器,可以实现两输出轴扭矩变比例分配,相当于增大了差速器的锁紧系数,即增加了差速器的防滑功能,从而有望提高车辆的越野通过性。组成行星齿轮差速器的三要素均为非圆柱齿轮,通过传动原理分析,给出了非圆节曲线的设计方法,并进行了示例计算。

英文摘要：

Integrated with three noncircular gear items, a new noncircular planetary differential was put forward, which may deliver variable proportional torque onto its two output axes. The new conceptive differential may be applied to off-road vehicles and may help to improve passing capacity. The driving theory and the design method of pitch curves were presented,and several case studies were illustrated.
