Abstract

A built-in cooling fan type magnetor used for a motorcycle comprises a flywheel (1), a bushing (2) and a stator (3), wherein, a strip bulge processed on the bushing (2) rotates with the rotation of the flywheel, liking a fan, which accelerates ventilation in the flywheel and speeds up air circulation, then the quantity of heat generated by a stator coil is rapidly emitted, thus the heat dissipation function is achieved. The built-in cooling fan type magnetor has the advantages of simple structure, easy implementation and low cost.

Description

A kind of motorcycle is with built-in cooling fan formula magneto

Technical field

The utility model is applied to motorcycle ignition system, particularly the cooling device of built-in fans.

Background technology

Now, motorcycle has developed into for a kind of amusement and recreation instrument, its function is more and more, so, also more and more higher to the demanded power output of magneto on it, simultaneously, want also miniaturization lightweight of cube, but the harmful effect that brings is exactly: the motor stator caloric value is increasing, understands the scaling loss stator coil when serious, influences the reliability of motor.It is that flywheel increases radiator fan outward or surges cold in addition or the oil cooling cooling system that existing solution adopted more: flywheel increases radiator fan outward, though can reduce coil temperature, but need to increase the fan installing space, increased the engine overall volume, and water-cooled or oil cooling system configuration are complicated, the assembling difficulty increases cost.

Summary of the invention

In order to address the above problem, the utility model provides a kind of engine overall volume that do not increase, cooling fan formula magneto simple in structure.

The utility model be the magneto flywheel 1. neck bush 2. above, process the strip projection, along with the rotation of flywheel, just like a fan, promote the flywheel inner air flow, quicken air circulation, thereby the heat that fast stator coil is produced distributes, played the effect of heat radiation, matching requirements have been reduced, not only play the cooling effect of fan, and do not increased the overall volume of magneto flywheel, reached good effect.

The beneficial effects of the utility model are: ingenious reasonable use the space between flywheel and the stator, increased the built-in fans of integral type, not only reached the effect of stator coil shape heat, and the magneto overall volume there is not influence, can not increase size of engine, in addition, this project organization is simple, implement easily, cost is low.

Brief description of drawings

Below in conjunction with accompanying drawing and example the utility model is further specified:

Fig. 1 is a magneto flywheel schematic diagram, 1 expression magneto flywheel among the figure, 2 expression linings.

Fig. 2 is the cutaway view of Fig. 1 flywheel, 3 expression magneto stator coil part schematic diagrames.

Fig. 3 is the schematic perspective view of magneto flywheel.

Preferred forms

In Fig. 1, above magneto flywheel 1 neck bush 2, process strip projection (lining is that stainless sheet steel is stamped to form, and it is shaped as Mould Machining, so the regular shape unanimity), seem a fan, when magneto flywheel 1 high speed rotating, lining 2 resembles a fan, quickens the flywheel inner air flow, thereby the heat that stator coil 3 produces is taken away, reached radiating effect.

This built-in fan, not only processing is simple, implement easily, and radiating effect is obvious, and magneto outward appearance and fitted position are had no effect, and is a kind of good solution.

Claims (1)

1. a motorcycle comprises flywheel (1) with built-in cooling fan formula magneto, and retainer (2) and stator (3) is characterized in that processing the strip projection on described lining (2).
