Description
Technical field
The present invention relates to a kind of bicycle hub device.
Background technology
Bicycle hub device is located on the propeller boss of wheel, and the design quality of flower hub device directly affects the performance of bicycle
As speed compares.The column foot of existing colored hub device is integrally formed with axle sleeve, the need for maintenance is installed, otherwise flywheel whole at different levels
It is removably mounted on column foot, or being all integrally formed with column foot, very limits to inconvenience in this way, not only installing and safeguarding, also office
The design of minimum level flywheel is limited.
Additionally, it is well known that, the flywheel number of teeth is fewer, and voluntarily speed is than higher, and the colored hub device of existing single speed bicycle
Minimum level flywheel be 9 teeth, the minimum level flywheel of the colored hub device of multi-speed bicycle is 11 teeth, and the structure of existing colored hub is caused
The speed of current bicycle than not there is breakthrough raising yet.
Furthermore, existing colored hub device is typically integrally formed using steel and is made, although steel intensity is good, weight mistake
Weight so that bicycle is difficult to realize lightweight.Traditional settling mode be changing aluminum structure into entirely with material in colored hub structure,
So as to realize lightweight.But can so cause flywheel, column foot rapid wear situation occur, though because aluminium light weight intensity not
It is enough, it is yielding.
The content of the invention
In view of the shortcomings of the prior art, it is contemplated that in a kind of bicycle hub for solving above-mentioned technical problem of offer
Device.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of bicycle hub device, it includes column foot, bearing, axle sleeve and flywheel group；
The axle sleeve is coaxially sheathed on outside bearing, and the column foot is coaxially detachably sheathed on outside axle sleeve, and flywheel group sets
In outside column foot.
Preferably, the minimum level flywheel of flywheel group is integrally formed with column foot.
Preferably, flywheel group only includes the minimum level flywheel.
Preferably, flywheel group includes the minimum level flywheel, some grades of flywheels being removably mounted on column foot and is sheathed on
Some flywheel pads on column foot；A flywheel pad is provided between every two adjacent flywheels.
Preferably, the assembling through hole of some along the circumferential direction uniform intervals distributions, each flywheel pad are opened up on each flywheel
The installation through-hole corresponding with assembling through hole is opened up on piece；Flywheel group also includes quantity with assembling through hole identical alignment pin；Often
One alignment pin assembles the installation through-hole of through hole and flywheel pad through the correspondence of some grades of flywheels step by step.
Preferably, the column foot is connected through a screw thread axle sleeve.
Preferably, column foot and flywheel group are made up of steel, and axle sleeve and bearing are made of aluminium.
Beneficial effects of the present invention are at least as follows：
1st, using the detachable design installed, ease of assembly is safeguarded, widens the design space of colored hub for column foot and axle sleeve.
2nd, the minimum level flywheel and column foot of flywheel group are integrally formed.In this way, may be such that the number of teeth of minimum level flywheel according to need
Be designed to it is as few as possible, so as to carry high ratio to greatest extent, while, it is ensured that other performances of bicycle are unaffected, for example,
The design of the number of teeth of minimum level flywheel can be less than 9 teeth, so as to break through existing speed than limitation.
3rd, column foot and flywheel group are made up of steel, and axle sleeve and bearing are made of aluminium.In this way, can both mitigate the weight of colored hub
Amount, can also ensure to spend the intensity of hub, realize lightweight while increasing the service life.
4th, the present invention can install the flywheel of correspondence series on column foot according to the shifting needs of bicycle, the size of column foot with
Traditional column foot size is identical, be can be applied on this flower hub device so as to conventional flywheel.Afterwards, then by column foot and flywheel group one
It is easy to assembly quick with being installed on axle sleeve.

Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described further：
Refer to Fig. 1 to Fig. 6, the present invention relates to a kind of bicycle hub device, its better embodiment include column foot 10,
Bearing 20, axle sleeve 30 and flywheel group.
The column foot 10 is in hollow and both ends open, and axle sleeve 30 is in hollow and both ends open, and axle sleeve 30 is coaxially sheathed on
Outside bearing 20, removably coaxial line is sheathed on outside axle sleeve 30 column foot 10, and flywheel is mounted on outside column foot 10.
In this way, column foot 10 uses the detachable design installed with axle sleeve 30, ease of assembly is safeguarded, the design for widening colored hub is empty
Between.
Preferably, the column foot 10 is connected through a screw thread axle sleeve 30.Specifically, the inner peripheral wall of column foot 10 is provided with recessed screw thread,
The outer circle wall of axle sleeve 30 is correspondingly provided with convex thread.
Wherein, the minimum level flywheel 41 of flywheel group is integrally formed with column foot 10.In this way, may be such that the number of teeth of minimum level flywheel
Be designed to as needed it is as few as possible, so as to carry high ratio to greatest extent, while, it is ensured that bicycle other performances do not receive shadow
Ring, for example, the design of the number of teeth of minimum level flywheel can be less than 9 teeth, so as to break through existing speed than limitation.
In the present embodiment, column foot 10 and flywheel group are made up of steel, and axle sleeve 30 and bearing 20 are made of aluminium.In this way,
Both the weight of colored hub can have been mitigated, can have also ensured to spend the intensity of hub, realize lightweight while increasing the service life.
Referring to Fig. 1 and Fig. 2, flywheel group only includes one and the integrally formed minimum level flywheel 41 of column foot 10, and it can be applied to
In single speed bicycle.
Referring to Fig. 3 to Fig. 6, in other embodiment, flywheel group include with the integrally formed minimum level flywheel 41 of column foot 10, can
Remove and install in some grades of flywheels 42 on column foot 10 and some flywheel pads 60 being sheathed on column foot 10.Every two adjacent fly
A flywheel pad 60 is provided between wheel 42.In this way, the flywheel 42 that can install correspondence series according to the shifting needs of bicycle arrives tower
On base 10, the size of column foot 10 is identical with traditional size of column foot 10, be can be applied on this flower hub device so as to conventional flywheel.
Afterwards, then by column foot 10 and flywheel group together it is installed on axle sleeve 30, it is easy to assembly quick.
Referring to Fig. 5, it is preferable that open up the assembling through hole of some along the circumferential direction uniform intervals distributions on each flywheel 42
421, the installation through-hole corresponding with assembling through hole 421 is opened up on each flywheel pad 60.Flywheel group also includes quantity with assembling
The identical alignment pin 70 of through hole 421.Each alignment pin 70 is step by step through some grades of correspondence assembling through hole and the flywheel pads of flywheel 42
The installation through-hole of piece 60, to reinforce flywheel group.
Need it is clear that, flywheel 42 refers to the flywheel in addition to minimum level flywheel 41 in flywheel group.
For a person skilled in the art, technical scheme that can be as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the protection model that should all belong to the claims in the present invention
Within enclosing.
