In which the motion law of suspension center is decided by designing a special curve for varied diameter wheel.

其中悬点运动规律是由设计的特殊曲线作为变径轮廓曲线决定的。

Center of mass below the suspension point.

重心在悬挂点下面。

But the basic idea is, then, that the center of mass will always in stable configuration line itself up below the point of suspension.

但是基本概念是，物体的重心将一直，处于稳定的结构线上，在悬挂点下面。

So the Pentagon awarded a 4-billion-dollar contract to build a version with a lower center of gravity and improved suspension.

Handling is impressive for a vehicle that weighs in a bit over 4600lbs -- thanks in great part to the low center of gravity, near 50-50 weight distribution and active air suspension.
