Flywheel arrangement for an internal combustion engine

摘要

The present invention relates to a flywheel arrangement for an internal combustion engine comprising a starter motor (1) having a pinion gear (2) at an output shaft. The pinion gear (2) constantly engages a corresponding crank gear of a crank wheel (3) located between an engine block and a flywheel assembly (9) of the engine. The crank wheel (3) is operatively connected to a crankshaft (4) of the engine via a one-way clutch unit (5). The flywheel assembly (9) comprises a first flywheel body (6) connected to the crankshaft (4) of the engine. A second flywheel body (7) is rotatable relative to the first flywheel body (6) and coupled thereto such that is able to move elastically through a limited angular distance relative to the first flywheel body (6). An interlocking device includes at least one locking arrangement (8) and is adapted to produce an interlocking connection between the second flywheel body (7) and the first flywheel body (6) during cranking of the internal combustion engine.
