Abstract

The utility model discloses a flywheel mechanism for hub-type electric bicycles, wherein the flywheel is pulled on the wheel axle in a rotary manner; one side of the flywheel is connected with the hub motor through the clutch. Since one side of the flywheel is connected with the hub motor through the clutch and the flywheel can directly be pulled on the wheel axle, diameter of the flywheel is not restricted by size of the clutch, thus diameter of the flywheel can be minimized; therefore, overall size of the electric bicycle can be smaller, enabling electric bicycles to be small in size and light in weight.

Description

The flywheel mechanism of hub-type electric bicycle
Technical field
The utility model relates to a kind of flywheel mechanism of hub-type electric bicycle.
Background technology
Popular along with Electrical Bicycle requires more and more stronger to the Electrical Bicycle weight-saving.Therefore steamboat footpath Electrical Bicycle also increases gradually.Wheel is little, and vehicle frame and chain drum are also corresponding to be reduced.After chain drum reduces, guarantee reasonable " stroke " (stroke is that crank rotates a circle distance that bicycle travelled) of bicycle, just need the corresponding diameter that reduces flywheel.Yet, the flywheel mechanism of existing hub-type electric bicycle, as Fig. 1, flywheel and wheel hub motor cooperatively interact by ratchet and ratchet, the inner ring of flywheel is that ratchet matches with the ratchet that is fixed on the wheel hub motor, the inevitable diameter of the diameter of its flywheel greater than ratchet, thereby limited reducing of flywheel wheel footpath.
Summary of the invention
The utility model purpose is to provide a kind of flywheel wheel footpath not limited by ratchet, can accomplish the flywheel mechanism of minimum hub-type electric bicycle.
The flywheel mechanism of hub-type electric bicycle described in the utility model, flywheel is rotating to be set on the wheel shaft, and a side of flywheel links to each other with wheel hub motor by power-transfer clutch.
Hub-type electric bicycle freewheel of the present utility model mechanism, a side of flywheel links to each other with wheel hub motor by power-transfer clutch, and flywheel can directly be enclosed within on the wheel shaft, and its diameter can not be subjected to the restriction of the size of power-transfer clutch, thereby flywheel diameter can be done minimumly.The diameter of flywheel can be minimum, and the size of so whole Electrical Bicycle also just can be littler, also just more helps the miniaturization and the lightweight of Electrical Bicycle.

The specific embodiment
Embodiment 1, as Fig. 2, Fig. 3, a kind of flywheel mechanism of hub-type electric bicycle, flywheel 1 two ends are installed on the wheel shaft 10 by steel ball 3,4 and axle bowl seat 5,6, relatively wheel shaft 10 is rotatable, and flywheel 1 and wheel hub motor 12 link to each other by ratchet device, and ratchet 2 is fixed on the wheel nave motor 12, one side of flywheel has ratchet 7, and ratchet 7 matches with the gear teeth 8 of ratchet 2.
Flywheel 1 also can be installed on the wheel shaft 10, as Fig. 4 by antifriction-bearing box 9.
Embodiment 2, as Fig. 5, and a kind of flywheel mechanism of hub-type electric bicycle, flywheel 1 two ends are installed on the wheel shaft 10 by steel ball 3,4 and axle bowl seat 5,6, and wheel shaft 10 is rotatable relatively, and flywheel 1 one ends link to each other with wheel nave motor 12 by overriding clutch 11.Overriding clutch is an existing product, and stage clip 13 is installed between overriding clutch 11 and wheel hub motor.The fitting surface of overriding clutch 11 is the unidirectional serration of intermeshing end face, as Fig. 6, Fig. 7.
