    • A flywheel with a torsional damper having two kind of spring mechanisms (30A and 30B), one spring mechanism (30A) directly connecting driving and driven side flywheels (10 and 20) and the other spring mechanism (30B) connecting the driving and driven side flywheels (10 and 20) via a friction mechanism (33). By this arrangement, the flywheel has two vibrational characteristics between which vibrational operation of the flywheel can shift depending on whether the friction mechanism (33) slides. The flywheel can pass through its resonance speed by shifting its operation from one vibrational characteristic to the other without being accompanied by a large amplification of vibration. In addition, since sliding at the friction mechanism (33) occurs only briefly, a good damping effect can be obtained at the usual range of engine operating speeds unlike a prior art flywheel with a continuously sliding hysteresis mechanism.
    • 具有扭转阻尼器的飞轮具有两种弹簧机构(30A和30B),一个直接连接驱动和从动侧飞轮(10和20)的弹簧机构(30A)和连接驱动侧和从动侧的另一弹簧机构(30B) 飞轮(10和20)经由摩擦机构(33)。 通过这种布置,飞轮具有两个振动特性,其中飞轮的振动操作可以根据摩擦机构(33)是否滑动而移动。 飞轮可以通过将其操作从一个振动特性转移到另一个而不伴随振动的大幅度放大而通过其共振速度。 此外,由于在摩擦机构(33)处的滑动仅短暂发生,与现有技术的具有连续滑动滞后机构的飞轮不同,在发动机运行速度的通常范围内可以获得良好的阻尼效果。
