Abstract
A split flywheel construction having a spring arrangement coupling two flywheel elements together which works by friction dependent on centrifugal force, so that the coupling of the flywheel elements is stiffened at higher speeds. At operating speeds, an undesirable flexibility of a drive train is thereby prevented while at low speeds and with low friction a low resonant frequency is obtained below the vibration frequencies occurring in the drive train at these speeds.
