adj.没有装弹簧的；未弹回的；未长芽的

With that in mind, the compression cycle controls the motion of the vehicle's unsprung weight, while extension controls the heavier, sprung weight. 因此，避震器在压缩循环时控制的时弹簧下部质量的运动，而伸展循环时控制的是弹簧上部质量。

The upper mount of the shock connects to the frame (i.e., the sprung weight), while the lower mount connects to the axle, near the wheel (i.e., the unsprung weight). 避震器的顶盖连接在车架上（弹簧支撑的重量），而避震器的底盖连接在车轴上，接近于车轮（非弹簧支撑的重量）。

With its strikingly curved, interrupted spokes, it not only looks superb but thanks to the lightweight construction method, keeps the unsprung weight to a minimum. 凭借其惊人的弯曲，中断辐条，它不仅看起来非常好，也采用了轻质结构的方法下，保持了弹簧的重量到最低限度。

The sprung mass is the mass of the vehicle supported on the springs, while the unsprung mass is loosely defined as the mass between the road and the suspension springs. 弹簧上方的质量是指弹簧上方支撑的车体的质量，而弹簧下方的质量通常是指路面与悬挂的弹簧之间的车体的质量。

The principle of lightweight construction on the chassis and suspension, in turn, guarantees supreme stability on low weight and minimizes the car's unsprung masses. 关于底盘和悬挂的原则，轻质结构，反过来，保证低体重最高的稳定性，减少汽车的非悬挂质量。
