From Fig.32.1,it can be seen that the propeller shaft applies to the shaft D a torque which,as it is transmitted through the bevel gearing,is increased in the same ratio as the speed is reduced.This increased torque is then transmitted through the shaft G to the road wheels.From Newton's third law of motion,we know that action and reaction must be equal and opposite,so not only will this torque tend to rotate the wheel,but also the reaction from the wheel will tend to rotate the shaft G in the opposite sense.Therefore,there will be a tendency for the pinion and its shaft D to swing bodily around the crown wheel,and this tendency will be reacted by the axle casing Some means therefore must be introduced to prevent the axle casing from rotating in the opposite direction.This may be simply the leaf springs themselves,or additional links - torque-reaction or radius rods - may be used and will be essential if coil,instead of leaf,springs are employed.

从图32.1可以看出,滚轴适用于轴D,它通过锥齿轮传递扭矩的,增加同样的比率,速度反而会降低.如果增加扭矩,然后通过传送轴G的车轮,从牛顿第三定律,可知,运动和方向必须相同,如果方向相反,不仅会改变轮子的运动,还会让轮子反方向旋转.因此,会有一个小齿轮轴的趋势,其D来左右摆动身体的冠轮,这个趋势将是由外壳,因此必须作出防止在相反方向旋转轴半轴套管一些措施.比如用简单的钢板弹簧,或者其他链接-半径棒(?)-也可以,这个辅助工具是很必要的,如果用线圈代替叶片的话,弹簧也会产生作用.
