Freewheel clutch bears excessive torque, causes to start freewheel clutch damage.
Utility model content
The purpose of this utility model, which is just to provide, a kind of effectively prevent what starting freewheel clutch damaged when being inverted to rub
Motorcycle engine start freewheel clutch protection mechanism.
The purpose of this utility model is that technical solution in this way is realized, a kind of motorcycle engine starting surmount from
Clutch protection mechanism, including starting motor and crankshaft, the magneto that tape starting freewheel clutch is provided on the crankshaft turn
Son, the starting motor are connect by secondary gear mechanism with the frictional gear wheel mechanism being arranged on crankshaft, the starting
Freewheel clutch one end is connect with frictional gear wheel mechanism.
Wherein, the frictional gear wheel mechanism includes gear wheel inner ring, and it is super to penetrate starting for circle center in the gear wheel
More in clutch；It is arranged with gear wheel outer ring on the gear wheel inner ring, the outer both ends of the surface in the gear wheel outer ring are equal
Friction coatings are provided with, gear wheel outer ring junction is provided with the rubbing machine contacted with friction coatings in the gear wheel inner ring
Structure.
It further describes, the friction mechanism includes setting in gear wheel inner ring outer both ends of the surface and is located at gear wheel
The platen A and platen B, the platen A and platen B of inner ring and gear wheel outer ring junction pass through the rivet across gear wheel inner ring
Connection；Disc spring and gasket, the gasket and one end face of gear wheel outer ring are provided between the gear wheel outer ring and platen A
Friction coatings contact, the platen B are contacted with the friction coatings of gear wheel outer ring other end.
In the present invention, the secondary gear mechanism includes intermeshing primary duplex-gear and secondary duplex-gear,
The primary duplex-gear is engaged with the output shaft of starting motor, and the secondary duplex-gear is engaged with gear wheel outer ring.
By adopting the above-described technical solution, the utility model has smart structural design, using reliable, low-cost
Advantage, starting freewheel clutch is rushed in reversion when can be effectively prevent due to the improper starting of engine and be shut down using it
It hits, buffer protection has been carried out to freewheel clutch, it is therefore prevented that the damage of freewheel clutch extends service life.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the portion A enlarged view in Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, but the utility model
These embodiments are not limited to, any improvement or substitution on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1: as shown in Figure 1, a kind of motorcycle engine starts freewheel clutch protection mechanism, including starting motor
1 and crankshaft 2, the magneto rotor 4 of tape starting freewheel clutch 3 is provided on the crankshaft 2, it is characterized in that: the starting
Motor 1 is connect by secondary gear mechanism with the frictional gear wheel mechanism being arranged on crankshaft 2, the starting freewheel clutch
3 one end are connect with frictional gear wheel mechanism.
Wherein, the frictional gear wheel mechanism includes gear wheel inner ring 5, and 5 center of gear wheel inner ring penetrates starting
In freewheel clutch 3；It is arranged with gear wheel outer ring 6 on the gear wheel inner ring 5, in the outer two of the gear wheel outer ring 6
End face is provided with friction coatings 7, is provided in the gear wheel inner ring 5 with 6 junction of gear wheel outer ring and connects with friction coatings 7
The friction mechanism of touching.
As shown in Fig. 2, the friction mechanism includes setting in the 5 outer both ends of the surface of gear wheel inner ring and is located at gear wheel
The platen A8 and platen B9, the platen A8 and platen B9 of inner ring 5 and 6 junction of gear wheel outer ring are by passing through gear wheel inner ring
5 rivet 10 connects；Be provided with disc spring 11 and gasket 12 between the gear wheel outer ring 6 and platen A8, the gasket 12 with
The friction coatings 7 of 6 one end face of gear wheel outer ring contact, and the platen B9 and the friction coatings 7 of 6 other end of gear wheel outer ring connect
Touching.
It further describing, the secondary gear mechanism includes intermeshing primary duplex-gear 13 and secondary duplex-gear 14,
The primary duplex-gear 13 is engaged with the output shaft of starting motor 1, and the secondary duplex-gear 14 is engaged with gear wheel outer ring 6.
In the present invention, gear wheel outer ring 6 is assemblied on gear wheel inner ring 5, and by being fixed on gear wheel inner ring 5
Platen A8 disc spring 11 is pressed on gasket 12,6 two sides of gear wheel outer ring have generate rub friction coatings 7, generate one can
Cause the frictional force of gear wheel outer ring 6 and the opposite sliding of gear wheel inner ring 5；When engine in improper starting or is shut down and generated
When reversion impact, the frictional force of gear wheel inner ring 5 and the generation of gear wheel outer ring 6 is greater than its maximal friction, generates skidding, prevents
Surpass from being impacted, thus effective protection surpass from.
