Description
Technical field
The present invention relates to a kind of bicycle gear part, more particularly to a kind of rigidity, intensity is higher and very light weight
Bicycle gear sprocket wheel.
Background technology
With the development of the society, the various vehicles are for lightweight, the requirement more and more higher of high intensity now.At present certainly
Driving carries out loss of weight typically by material lightweight with structure lightened, and lightweight is that have enough with intensity and rigidity
Guarantee premised on, for sports bicycle, its intensity to speed-changing chain and rigidity have it is higher will
Ask.And speed-changing chain is one of most important parts in bicycle, its basic performance requirement is in the certain situation of quality
Under, intensity is the higher the better with rigidity, i.e. specific strength and specific stiffness is the higher the better.
The structure wheel group that the speed-changing chain of bicycle be arranged in parallel for the gear ring of multilayer different-diameter, generally there is two kinds of typical cases
Structure type, a kind of to be punching press gear ring be stacked the speed-changing chain to be formed by riveting（Using SHIMANO as representative）, it is another
Kind is a kind of taper（Or cone pulley）The gear ring that hollow body does the multilayer different-diameter of supporter parallel is located at its cylindrical integral type
Sprocket wheel（Using SRAM as representative）.It is more that former product punching press gear ring, which is stacked by riveting and to form the product of speed-changing chain,
Number, often rigidity is smaller with intensity, and bearing capacity is weaker, and heavier mass, but processing technology is good；Latter is taper
（Or cone pulley）Hollow body structure, and be typically to be process by a block of material, thus there is higher intensity and rigidity, also simultaneously
With lighter quality.This taper（Or turriform）The sprocket wheel of hollow body structure, there are two kinds of structures, one is, it will hold greatly
Gear ring is made of one with spoke, is then axially connected into an entirety with the conical hollow body structure of the gear ring with small end again
Speed-changing chain；The second is big end tooth circle and small end gear ring all integral productions form conical hollow body structure, then spoke is flush-mounted in
The inner circle of big end tooth circle is axially connected with conical hollow body structure simultaneously.But either which kind of assembling structure, it is required for
Center steering position between small end gear ring and big end tooth circle sets a support cylinder, that is, passes through the spoke held greatly and taper
When hollow body structure axially connects, the support cylinder is clamped in the spoke held greatly and small end gear ring between the two, to bear
Axial force during installation.The support cylinder gap, which coordinates, to be socketed on wheel hub, so as on the rear axle of bicycle.Due to
The reason for said structure, it is not carried out between the large end face of bull gear, the small end face of conical hollow body and support cylinder rigid
Connection, only by the chucking power realization axially connection of both ends of the surface.Therefore, between large end face and small end face can only resistance to compression and can not
Tension, and moment of torsion can not be transmitted by support cylinder between large end face and small end face, particularly when conical hollow body exists
When being deformed after being turned round, conical hollow body have side axially outward open trend, and due to support cylinder can only resistance to compression not
Energy tension, thus outside nut mounted on hubs can only be relied on to prevent conical hollow body from axially deforming laterally, so
Then greatly weaken its intensity and rigidity.
Therefore, it is high that a kind of in light weight, intensity and rigidity how to be provided, meets the speed varying chain of sports bicycle big load operation
Wheel is industry urgent problem to be solved.
The content of the invention
The present invention is not high with rigidity in order to solve the intensity of existing bicycle variable speed chain wheel, is not met by sports bicycle
The technical problem of big load operation, propose that a kind of in light weight, intensity and rigidity are high, meet the operation of sports bicycle big load from
The integrative-structure of driving disc and wheel hub and the speed-changing chain with the integrative-structure.
The integrative-structure of a kind of disc and wheel hub proposed by the present invention, it includes the disc of integral production and wheel hub.It is described
Disc is located at described wheel hub one end, and the excircle part of disc is provided with attachment structure.
Preferably, described disc is provided with lightening hole.
Preferably, the endoporus of the wheel hub is provided with spline, and loss of weight annular groove is additionally provided with the middle part of wheelboss inner hole.
Preferably, the excircle part of the disc is provided with attachment structure at least threaded connection, key connection, riveting, welding
Or one kind of interference connection.
The present invention also proposes a kind of speed-changing chain of the integrative-structure with described disc and wheel hub, the disc outside
Circle is adapted to connection, described disc and the adjacent teeth in the conical hollow body structure with small end gear ring with the inner circle of big end tooth circle
The disc connection of circle, the cylindrical connection of described small end gear ring and the wheel hub.
Preferably, the cylindrical and connection of the inner circle of big end tooth circle of the disc for be threadedly coupled and/or welds, interference company
Connect and weld or one kind of key connection.
Preferably, the connection of the described disc disc adjacent with big end tooth circle is riveting and/or welding, screwing
It is a kind of.
Preferably, the small end gear ring of the speed-changing chain is at least threadedly coupled with the cylindrical connection of the wheel hub, key connects
Connect, rivet, welding or interference connection one kind.
The present invention is by disc and the integral part of wheel hub integral production, when itself and the conical hollow body with small end gear ring
After structure axially connects into an Integral variable-speed chain wheel, its axial section for a firm triangular support structure, so as to pole
The big intensity and rigidity that improve flywheel, the bicycle ridden especially suitable for competition type player.Disc is one with wheel hub
Part made in one piece, thus its accuracy of manufacture is easy to ensure, so as to be advantageous to improve the precision after assembling, so as to be more conducive to protect
Demonstrate,prove the gearshift performance of sprocket wheel.Described disc is circumferentially with lightening hole along it, and loss of weight annular groove is additionally provided with the middle part of wheelboss inner hole.
Ensure chain sprocket structure with the case of very high intensity and rigidity, the reasonable layout of lightening hole and loss of weight annular groove can make with opening up
Obtaining speed-changing chain has lighter quality, in favor of riding.The present invention is simple in construction, and easy making process, cost is relatively low, is easy to promote
Using.
