Internal-combustion engine starting device, has device that is designed and driven in accordance with wheel and clutch, so that noises have frequency that is shifted to upper critical frequency of audio frequency range perceptible by human

摘要

The device has a circular gear wheel (3) rotatably held at a crankshaft of an internal-combustion engine (5) and constantly staying in mesh interference with an intermediate gear wheel (25). A one-way clutch (4) is arranged between the wheel (3) and the crankshaft to transfer torque of the wheel (3) to the crankshaft over an interference element (42). A device is designed and driven in accordance with the wheel (3) and the clutch, so that noises caused by the wheels and the clutch have frequency that is shifted to an upper critical frequency of an audio frequency range perceptible by human.
