摘要： Vibrations in the rear wheel caused by variations in the driving power transmitted to the rear wheel via the chain or movements transmitted to the rear wheel from the road surface are damped. The rear wheel includes an axle, a wheel hub, a plurality of bearings, an annular member, a sprocket, elastic members, and a damping mechanism. The axle is inserted into the wheel hub. The bearings are located between the wheel hub and axle such that the wheel hub, bearings and axle are arranged in a radial direction of the wheel hub. The annular member is positioned to be rotatable relative to the wheel hub in a circumferential direction of the wheel hub. The sprocket is coupled to the annular member and the chain is wound around the sprocket. The elastic members elastically deform when the annular member is rotating relative to the wheel hub. The damping mechanism damps vibrations that act to displace the annular member relative to the wheel hub in a circumferential direction with respect to their positions after the rotation of the annular member relative to the wheel hub.

摘要翻译：通过链条传递到后轮的驱动力或从路面传递到后轮的运动的变化引起的后轮振动被衰减。后轮包括轮轴，轮毂，多个轴承，环形部件，链轮，弹性部件和阻尼机构。轴插入轮毂。轴承位于轮毂和轮轴之间，使得轮毂，轴承和轮轴沿轮毂的径向布置。环形部件被定位成可相对于轮毂沿轮毂的周向方向旋转。链轮与环形部件连接，链条缠绕在链轮上。当环形构件相对于轮毂旋转时，弹性构件弹性变形。阻尼机构在环形构件相对于轮毂旋转之后衰减振动，该振动用于使环形构件相对于轮毂相对于它们的位置在圆周方向上移位。
