Description
Technical field
The present invention relates to bicycle art, in particular to a kind of two-stage multi-speed bicycles.
Background technique
The transmission system of bicycle is the very crucial a part of bicycle, and effect is exactly the literal meaning.Mainly
The strength of human body, it is transmitted to the wheel set system of bicycle, so that bicycle be made to generate the power that can be run.
Bicycle transmission system is mainly divided into two major classes at present, and one kind is the transmission system of variable-ratio, in addition be exactly
The transmission system of single speed.The transmission system type selected for different road conditions and the different modes of riding is also inconsistent.
In addition there are also the two-stage occurred to obtain higher speed transmission or Multi-stage transmissions.The bicycle level-one list of the prior art
The disadvantage of speed is the slow of race；The bicycle of variable-ratio is also that primary transmission speed is also not quickly after all；More than two-stage voluntarily
Vehicle can be run fast, but difficulty in starting.Also a kind of is exactly interior change, and this is like this speed change of speed changer of automobile gearbox
Device be not only it is complicated and more expensive, maintenance price is also expensive, so being rarely employed now.The ordinary bicycle of the prior art,
Either single speed or variable-ratio because be all level-one gear ratio, speed will not quickly, it is extraordinary to physical efficiency from
It cannot give full play to for driving fan because happy brought by speed.For current two-stage or Multi-stage transmission from
Driving, the difficulty in starting if speed ratio is too big, goes up a slope difficult, and speed ratio is too small cannot equally to play the faster mesh for allowing bicycle to run
's.There are also a kind of devices of rarely found internal gear transmission, and complexity is high, inconvenient maintenance.
Summary of the invention
The technical problem to be solved by the present invention is to providing one kind in view of the above problems should make bicycle be easy starting, again
Want bicycle energy high-speed cruising.And it is technically simple；It is reliable for operation；It is easy to maintenance；It is low in cost；Energy-saving and environment-friendly technical solution.

Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings.
The present invention in the specific implementation, a kind of two-stage multi-speed bicycle, including bike rack 1, the bike rack 1
On axis 2 is installed, central shaft chain wheel group 5 is installed, the central shaft chain wheel group 5 is by three chains differing in size on the axis 2
Wheel forms, and gear A 3 is also equipped on the axis 2, and cooperation is equipped with gear B 4 in the gear A 3, fixes in the gear B 4
One sprocket wheel 6, unilateral bearing is equipped with inside the gear B 4, and the gear B bracket 8 supports one end, the tooth by hinges 7
The other end of B bracket is taken turns by the speed changer beside the connection Handlebar of bicycle of speed changer wirerope 15, the bicycle rear shaft spine
Sun gear 9 is installed, 9 side of sun gear is equipped with planet carrier 10, is equipped with planet tooth in the planet carrier 10 on wheel
Wheel 11,11 radial outside of the planetary gear cooperation are equipped with gear ring 12, and the gear ring 12 is axially external to be equipped with gear ring sprocket wheel 13, institute
It is axially external equipped with planet carrier sprocket wheel 14 to state planet carrier 10.
It is set on the planet carrier 10 there are three planetary gear, the planetary gear 11 is fitted in planet carrier.
The sun gear 9 is fixed on the ratchet of bicycle rear shaft, and gear ring 12 and planet carrier 10 are located at the sun
The both sides of gear 9.
The gear B bracket 8 is mounted on axis in the following, one end is supported by hinge 7, and the other end is connected certainly by wirerope 15
Speed changer beside hand handle of driving a vehicle.
Unilateral bearing is installed, the unilateral bearing is by sprocket wheel 6, and chain, gear ring sprocket wheel 13 is unidirectionally in the gear B 4
Lock gear ring sprocket wheel.
The working principle of the invention: the characteristics of this technology is secondary transmission, and the first order is the transmission of variable-ratio sprocket wheel chain, the
Second level is variable-ratio Planetary Gear Transmission, due to two-stage transmission can speed change, so riding for bicycle just becomes easier to.
1. bicycle starts:
Can be used axis minor sprocket cooperation secondary transmission lower-speed state (allow one-way clutch gear B be detached from
Shaft gear A)；
2. riding when going up a slope:
As state when bicycle starting, relatively slow slope also can be used axis relatively big sprocket wheel and maximum chain
Wheel；
3. level road is ridden:
Use the maximum sprocket wheel of the first order；If the state at a slow speed of the cooperation second level, speed at this moment should with it is current
Primary transmission multi-speed bicycle rapid pace it is suitable；If road conditions are preferable, second level planetary gear speed-changing can be switched to
The fast state (gear B and the gear A of axis is allowed to engage) of device can thus increase speed ratio, accelerate the speed of bicycle.
4. the cooperation of 3 high lower-speed states of chain drum and planetary transmission of different sizes by axis chain drum group,
Bicycle can have 6 kinds of speed that can select in riding, and ride so just more casual, and adaptation population is also relatively wide.
In conclusion the present invention solves substantially is easy starting and fast contradiction of riding, also has and adapt to most of landform
Function.
Technical solution implementation method:
On the hind axle of existing multi-speed bicycle, transmission flywheel is removed, then installs a planetary transmission, such as
Upper figure: the sun gear of speed changer is fixed on the ratchet of bicycle, and gear ring and planet carrier are located at the both sides of sun gear, and all
Sprocket wheel is installed, the sprocket wheel on planet carrier passes through the axis chain drum group of chain connection bicycle, and the chain drum on gear ring links gear B
The chain drum of upper fixation, gear B are engaged with the gear A being installed on axis or are detached to increase or reduce when needed
Speed ratio.
A gear B bracket is installed below in the axis of bicycle；Install a gear on axis additional again on bicycle middle shaft
A as above schemes.
When cycling, be by sun gear transmit power, move ahead when, axis chain drum drive planetary plate chain drum according to
It is rotated clockwise, needs fixed gear ring that sun gear could be driven to rotate clockwise at this moment to drive bicycle to move ahead.Gu
The method of fixed tooth circle is to allow fixed sprocket wheel in gear ring chain drum and gear B by chain connection, is equipped with unilateral bearing in gear B
Prevent gear ring from following planet carrier to rotate clockwise, achievees the purpose that monodirectional locking gear ring, bicycle is allowed normally to ride.(at this time
State we be known as the lower-speed state of planetary transmission) need accelerate move ahead when, according to the characteristic of planetary transmission, allow
In gear B and bicycle middle shaft on one-way clutch gear A engagement, such gear ring sprocket wheel will counter-clockwise direction rotation,
The speed ratio of (what is known as the fast state of planetary transmission to state at this time) due to increasing entire transmission system, so
Bicycle can be with full speed running.Speed at this time can be than common multi-speed bicycle is fast on the market now.
Such a succinct two stage speed change bicycle, structure is simple, cheap, easy to maintenance, be one can be general
And novel transmission system bicycle, the favor being bound to by numerous cycling enthusiasts.
