ABSTRACT:
A split flywheel for reducing the transmission of vibrations from the engine to the drive shaft at certain frequencies of the flywheel is provided. Included are two flywheel elements drivingly connected to one another wherein one of which is connected or can be connected in a driven manner to the engine and the other of which is connected or can be connected in a driven manner to the drive line. The resonant frequency of the split flywheel unit is well below the frequency of engine vibrations which occur during normal traveling, so that only slight amplitudes of vibration occur between the flywheel elements during normal travel operation. However, during start-up of the engine, the resonant frequency of the flywheel is passed through. The drive connection between the elements a slip clutch having a greater friction contact than the maximum torque of the engine, placed in series with a spring mounting and positioned between the two flywheel elements. The slip clutch becomes operative only when the resonant frequency of the flywheel is passed through.
