In order to describe the technical characterstic place of the present invention in detail, lift preferred embodiments below and coordinate accompanying drawing
After illustrating such as, wherein:
As shown in Figures 1 to 4, a kind of bicycle that a preferred embodiment of the present invention is provided is put double
Motor small teeth number difference planet gear speed change gear 10, mainly by shell 11, small teeth number difference planet gear group
21, an assist motor 31 and a variable speed driver 41 are formed, wherein:
This shell 11, is fixed on the vehicle frame (not shown) of this bicycle, and pivotally pivot
It is located at the crank axle 91 of this bicycle.
This small teeth number difference planet gear group 21, mainly has ring gear 22, two external gear 23, a pair of inclined
24, support plate 25 of spindle sleeve, plural number trundle 26 and an output panel 27；This ring gear 22 be by
One first isolator 221 so that this crank axle 91 can be sheathed in the way of single direction rotation, this double-eccentric shaft set
24 is to be sheathed on this crank axle 91 in the way of direct or indirect rotationally, and this double-eccentric shaft set 24
Having a two eccentric segments 241 and section 242 without acceptance of persons, this two external gear 23 respectively has plural pin-and-hole 231,
And pivotally it is sheathed on this two eccentric segment 241 and the anglec of rotation phase of this double-eccentric shaft set 24
Differ from 180 degree, and this two external gear 23 be bridle joint in this ring gear 22, this support plate 25 is with rotatably
Mode be sheathed on this double-eccentric shaft set 24 section 242 without acceptance of persons, those trundles 26 are each passed through this
Those pin-and-holes 231 of two external gears 23 and be fixedly arranged on this support plate 25 and this output panel 27, this output
Dish 27 is pivotally to be sheathed on this crank axle 91, and is directly or indirectly connected to this bicycle
In put fluted disc 93.
The kinestate of this small teeth number difference planet gear group 21 is as shown in Figures 3 and 4.Wherein, shown in Fig. 3
It is that this double-eccentric shaft overlaps 24 states being positioned at 0 degree of position；It is then that this double-eccentric shaft overlaps 24 shown in Fig. 4
State in 60 degree of positions.
In the present embodiment, it is as a example by this double-eccentric shaft set 24 is sheathed on this crank axle 91 indirectly, and
And as a example by this output panel 27 is indirectly coupled in this put fluted disc 93, its framework is: also include a biography
Dynamic set 29, is pivotally sheathed on this crank axle 91, and this double-eccentric shaft set 24 is rotationally
Being sheathed on this drive sleeve 29, and be indirectly sheathed on this crank axle 91, this output panel 27 is then by this transmission
Set 29 is connected in this put fluted disc 93 in an indirect way.Certainly, the most also can not be by this transmission
Overlap 29 and be directly attached, and owing to this kind of mode can be deduced by the accompanying drawing of the present invention easily,
The most no longer represent with accompanying drawing, and repeat no more.
This assist motor 31, is arranged in this shell 11, and is connected to this ring gear 22, to turn this
Ring gear 22.In the present embodiment, this assist motor 31 is again via a belt by a reducing gear 32
Wheel 33 is connected to this ring gear 22.But, on reality is implemented, this assist motor 31 also can directly connect
It is connected to this ring gear 22, not to set up this reducing gear 32 and this belt pulley 33 for necessary.
This variable speed driver 41, is arranged in this shell 11, and is connected to this double-eccentric shaft set 24, uses
Turn this double-eccentric shaft set 24.
On reality is implemented, this assist motor 31 and this variable speed driver 41 are connected to a motor control
Device 51, this two motor controller 51 can be located at this shell 11, and be electrically connected with in this when arranging
Assist motor 31 and this variable speed driver 41.
Aforesaid rotating annexation, in addition to using the technical characteristic of isolator, remaining
Rotating annexation all can use bearing to connect, and in the accompanying drawing of the present invention, the most all shows
Go out to use the state of bearing.
It is explained above the structure of the present embodiment, next the mode of operation of the present embodiment is described.
Refer to Fig. 1 to Fig. 4, operation time, the trample action of rider can by this crank axle 91 via
This first isolator 221 turns this ring gear 22 in the way of unidirectional turning, and then turns this two external tooth
Wheel 23, the rotation of this two external gear 23 is i.e. driven those trundles 26 together with this by those pin-and-holes 231
Support plate 25 and this output panel 27 rotate, and then drive this drive sleeve 29 to rotate, and related turning puts tooth in this
Dish 93 drives the chain (not shown) of bicycle that bicycle is advanced.At the same time, by controlling
This variable speed driver 41 drives this double-eccentric shaft set 24 rotation, and then drives this two external gear 23 to produce bias
Motion, thus can change this two external gear 23 rotating speed relative to this ring gear 22.Change this outside two
Gear 23 i.e. can allow rider feel changing of gear ratio when trampling relative to the rotating speed of this ring gear 22
Become.
Additionally, during trampling, this assist motor 31 turns the driving that this ring gear 22 is provided
Power can be as the power-assisted of auxiliary stampede power.
Referring again to Fig. 5, the rotor 311 of this assist motor 31 also can be by one second isolator 35 with can be single
It is arranged at this shell 11 to the mode rotated.Owing to this variable speed driver 41 is turning this double-eccentric shaft set 24
Time, it is possible to the reversion of this ring gear 22 can be caused because of the dynamic of this two external gear 23, and then band
This assist motor 31 dynamic inverts.Therefore, this second isolator 35 is set so that this assist motor
Therefore 31 will not invert, and then this ring gear 22 will not be inverted.And ring gear 22 will not invert
The pushes pedals i.e. representing rider will not invert, and therefore the present invention solves the trample action of rider
The anti-problem pushed away of driving force can be suffered from.
From the foregoing, it will be observed that the present invention can be reached the continuous variable speed of bicycle by small teeth number difference planet gear framework
Effect；Additionally, in the situation that the rotor 311 of this assist motor 31 is arranged this second isolator 35
Under, it is also possible to prevent the problem that ring gear 22 inverts, and then also solve the trample action meeting of rider
Suffer from the anti-problem pushed away of driving force.
