Can be two connections of element internal.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
Concrete structure is as Figure 1-Figure 2.Fig. 1 for the utility model provide it is a kind of with new drive component voluntarily
The structural representation of car；Fig. 2 is the signal of the structure of the drive component of the bicycle with new drive component shown in Fig. 1
Figure.
A kind of bicycle with new drive component that the present embodiment is provided includes bicycle main body and installed in institute
State the drive component in bicycle main body；
Wherein, drive component includes pedal rod structure, ring gear 22, external toothing 1 and rotating shaft 6；
Pedal rod structure is connected with each other with external toothing 1 and fixation is integrally formed, and external toothing 1 is set in the outside of rotating shaft 6, outward
Gear ring 1 can rotate around rotating shaft 6, and both separate can rotate；
Ring gear 2 is arranged on the inside of external toothing 1, and between the two by toothing drive connection；The ring gear 2 is arranged
In the outside of rotating shaft 6, and the ring gear 2 can drive rotating shaft 6 to rotate in the lump therewith；
Preposition sprocket wheel 3 is also arranged with rotating shaft 6, the preposition sprocket wheel 3 can be rotated with the drive of rotating shaft 6；
The preposition sprocket wheel 3 is connected by chain 5 with rearmounted sprocket wheel 4, and preposition sprocket wheel 3 passes motion to chain
5, rearmounted sprocket wheel 4 is further passed to, so as to drive rearmounted sprocket wheel 4 and rear wheel to rotate.
When people drive pedal rod structure to positive direction, external toothing 1, ring gear 2, rotating shaft 6, preposition sprocket wheel are driven successively
3rd, chain 5 and rearmounted sprocket wheel 4 rotate or mobile, and most power and motion are delivered to rear wheel at last, so as to drive bicycle
Walking；When people drive pedal rod structure round about, external toothing 1 is reversely rotated, because ring gear 2 uses ratchet knot
Structure, from without following external toothing 1 to reversely rotate, from the normally travel without influenceing bicycle.By above drive component, effectively
Reduce due to the phenomenon that the chain 5 that pedal rod structure reverse drive is brought drops, the traveling for giving people brings conveniently.
In the optional technical scheme of the present embodiment, internal tooth arrangement is uniformly arranged in the inside circumference of external toothing 1, while
Outer toothing is uniformly arranged in the outer circumference of ring gear 2, and internal tooth arrangement is engaged with outer toothing, by external toothing 1
Rotation can drive ring gear 2 to rotate by internal tooth arrangement and outer toothing, so as to realize that power and motion are transmitted from external toothing 1
To ring gear 2.
When external toothing 1 rotates to positive direction, ring gear 2 is driven to rotate with；When external toothing 1 rotates in the opposite direction,
Ring gear 2 is not reversely rotated therewith, and is to continue with being rotated to positive direction, so as to realize the reverse rotation of external toothing 1 or stop
The only motionless purpose for not influenceing bicycle normally travel.
In the optional technical scheme of the present embodiment, outer toothing uses ratchet structure, and the ratchet structure can be with respect to internal tooth
Circle 2 turns an angle, and is additionally provided with return element between ratchet structure and ring gear 2；When external toothing 1 is rotated forward,
Ratchet structure protrudes in the presence of return element and is abutted against with the internal tooth arrangement of the inner side of external toothing 1 such that it is able in driving
Gear ring 2 rotates with external toothing 1；When external toothing 1 reversely rotates or be slack, now ring gear 2 is rotated forward, and spine
Toothing is rotated forward with ring gear 2, and the ratchet structure touches internal tooth arrangement and depresses return element, it is achieved thereby that
Ring gear 2 is mutually disengaged with external toothing 1.
In the optional technical scheme of the present embodiment, pedal rod structure includes pedal rod 7 and pedal 8；Wherein, pedal rod 7
One end is fixedly connected with external toothing 1, and for driving external toothing 1 to be rotated around rotating shaft 6, the other end and the pedal 8 of pedal rod 7 connect
Connect；And external toothing 1 and pedal 8 are separately positioned on the both sides of pedal rod 7 so that people driven when pedal 8 is pedaled pedal rod 7 and
External toothing 1 rotates, so that the preposition sprocket wheel 3 for driving ring gear 2 and being coaxial therewith setting rotates；Then after chain 5 drives
Put sprocket wheel 4 to rotate, finally realize the normal walking of bicycle.
The bicycle with new drive component that the present embodiment is provided is difficult due to the drive component when reversely rotating
Chain 5 is caused to be dropped from sprocket wheel, so as to reduce inconvenience of the people when riding；Simultaneously according to this feature, can also be to this
The carrying out of the bicycle with the new drive component dress that embodiment is provided, the disabled person in order to be applied to some single legs makes
With, and for disabled person concrete condition only side set pedal rod structure.
Flexible member is set between pedal rod structure and bicycle main body, or between pedal rod structure and rotating shaft 6, from
And cause that pedal rod structure makes it revert to original position when turning an angle by flexible member.
The flexible member is specially：It is extension spring between pedal rod structure and bicycle main body；Pedal rod structure and rotating shaft 6 it
Between be torsion spring.
Finally it should be noted that：Various embodiments above is only used to illustrate the technical solution of the utility model, rather than it is limited
System；Although being described in detail to the utility model with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
