Wheel 44 and second another power gear in power gear 45, the first power gear 44 transmit power to the through elastic component 42
Two power gears 45.
Second power gear 45 is engaged in the first driven gear 46 with side, and the second power gear 45 is simultaneously engaged with the other side
In the second driven gear 48.From in Fig. 3 B as it can be seen that cabinet 40 and have first perforation 4002h and second perforation 4004h, first
Corresponding first driven gear 46 of the 4002h that perforates, the second corresponding second driven gear 48 of perforation 4004h.Wherein, the first driven gear
46 and second driven gear 48 be all that sector gear is preferred respectively, under the situation for not lowering effect, whole weight can be mitigated
Amount.
Cooperating Fig. 1, described in 2, fixed part 34 is affixed to vehicle frame 16, and it is socketed and axis is connected to the first perforation 4002h, opposite tooth
Roller box 32 rotates, and there is fixed part 34 first shaft 50 to connect the first driven gear 46.Guide chain portion 36 is to contact chain 12, set
It connects and axis is connected to the second perforation 4004h, also opposed gear case 32 rotates, and there is the second shaft 52 to connect the second driven gear 48.
Then, when the first power gear 44 rotates, the second power gear 45, elastic component 42 can be driven through elastic component 42
It can disperse the stress of moment concentration.It is passive that second power gear 45 of rotation can rotate the first driven gear 46 and second simultaneously
Gear 48 will also rotate fixed part 34 and guide chain portion 36 simultaneously.Since fixed part 34 is fixed on vehicle frame 16, so, by
The combination of fixed part 34 and the 36 two different directions components in guide chain portion, so that it may which the guide chain gear 3602 for controlling guide chain portion 36 is stirred
Chain 12 arrives opposite sprocket wheel 14 to correct position, achievees the purpose that gear shift.
Please refer to the schematic diagram that Fig. 4 A and Fig. 4 B, Fig. 4 A are elastic component 42 and power gear of the present invention.Fig. 4 B is this hair
The enlarged drawing of bright elastic component 42 and the second power gear 45.At least one corresponding described elastic component 42 of first power gear 44 has
At least a positioning hole 4402h, there are four elastic component 4 and four location hole 4402h, the second power gear 45 packets for tool in illustrated example
Containing gear part 4502 and linkage part 4504, gear part 4502 and the concentric combination of linkage part 4504, linkage part 4504 is provided with more
Several linked slot 4504S, gear part 4502 and the first driven gear 46 with and the second driven gear 48 engage.Elastic component 42 includes
Fixed part 4202, elastic portion 4204 and fastening part 4206, the first end of aforementioned elastic parts 42 are fixed part 4202, elastic component 42
Second end be fastening part 4206.Elastic component 42 is fixed on the first power gear 44, bullet with fixed part 4202 in this illustrated example
Property part 42 with the elasticity of elastic portion 4204 and be separably incorporated into the second power gear 45.
Fixed part 4202 is insertion to be fixed on location hole 4402h, and elastic portion 4204 connects and extend self-fixed department 4202,
Fastening part 4206 connects and extends from elastic portion 4204, and there are four turnovers with self-fixed department 4202 for the tool of elastic portion 4204 in illustrated example
Fastening part 4206 is extended to, because multiple turnovers there can be enough length, and has sufficient elastic effect.Fastening part 4206
The linked slot 4504S that can be set in grade linked slots 4504S.When the moment stress that elastic component 42 is subjected to is greater than energy load
Elastic force when, fastening part 4206 can slip originally where linked slot 4504S, slided into along the outer rim of linkage part 4504 next
Linked slot 4504S, therefore, the stress uprushed will be released, and reduce the injury to gear.
Referring to Fig. 5, Fig. 5 is the schematic diagram of driving unit of the present invention.Driving unit of the invention is motor 60, such as aforementioned
Bicycle electric rear chiain-moving device 30, wherein gear-box 32 can more further include motor 60 and transmission mechanism 62, motor
60 and transmission mechanism 62 be all arranged in cabinet 40, motor 60 receives electric power to generate power, and electric power can be for example from electricity
Pond.The power output axis connection transmission mechanism 62 of motor 60, transmission mechanism 62 are connected to the first power gear 44, so that first is dynamic
Powershift gear 44 is connected to driving unit.
Transmission mechanism 62 is possible there are many implementing, to contain worm gear, worm screw and many gears for legend, because of its implementation
Mode multiplicity, but this case technical characteristic is not influenced, as long as transmission mechanism 62 reliably has 60 driving force of motor in small space
Effect is transferred to the first power gear 44, and no longer redundant later in this.Wherein linkage part 4504 and gear part of the invention
4502 can also be integrally formed structures.
Therefore, using a kind of bicycle electric rear chiain-moving device 30 provided by the present invention, first is connected to by elastic component 42
Power is transmitted between power gear 44 and the second power gear 45, the improper stress uprushed can be dispersed, avoid gear failure, and borrow
It is all adopted as the design of sector gear by the first driven gear 46 and the second driven gear 48, keeps overall structure firm and lightweight
Change, also, structure can be combined with 60 driving unit of motor whereby, it is ensured that the smooth degree of gear shift, and bicycle can be substantially improved
Control impression.
By the above detailed description of preferred embodiments, it is intended to more clearly describe feature and spirit of the invention,
And not scope of the invention is limited with above-mentioned disclosed preferred embodiment.On the contrary, the purpose is to uncommon
Various changes can be covered and have being arranged in the scope of the claim to be applied of the invention of equality by hoping.
