The utility model relates to a driving flywheel with a small lag angle. The utility model is characterized in that the driving flywheel comprises an outer ring 1, and an inner ring 4. The inner ring of the outer ring 1 is provided with a plurality of ratchets 2, and the outer ring of the outer ring 1 is provided with a plurality of external teeth 3 which are engaged with other gears or chainwheels. The periphery of the inner ring 4 is provided with two detents 5 and a detent groove 6. The detents 5 can rotate upwards and downwards in the detent groove 6. A certain distance is formed between the two detents 5, which makes the detents 5 respectively engaged with the two ratchets 2 of the outer ring 1. The utility model relates to a detent type driving flywheel with a small lag angle of 10 DEG-12 DEG, which can reduce the phenomena of the interruption and the lag of the driving, and therefore, the deadweight loss of the mechanical power is reduced. The utility model has the advantages of simple structure, small volume, and flexible driving. The utility model is suitable for the transmitting torque of the unidirectional rotation and the transmitting torque of the roundtrip rotation, and is widely applied to the mechanical equipment or the vehicles, such as the small-size car, the bicycle, the yacht, etc., which require various continuous or intermittent transmitting torques.
