Abstract
It is a kind of that there is the carbon fibre rim with boss carbocyclic ring, including a cricoid closed chamber, the side wall of the chamber is equipped with the position of foetus hole slot for being used for housing the inner tube of a tyre toward the direction extension away from wheel circle center, carbocyclic ring is equipped with the chamber, the side wall of carbocyclic ring is equipped with some boss, and the boss is equipped with the spoke hole for being used for installing spoke.The utility model using carbon fiber can post forming characteristic, on the basis of the original moulding of product is not influenced, it will be buried in carbocyclic ring with boss well prepared in advance inside wheel rim, spoke hole is designed at boss, it greatly reduces the weight of product again while the integral strength of product is improved, so as to improve product competitiveness in the market.
Description
Technical field
The utility model is related to a kind of has the carbon fibre rim with boss carbocyclic ring.
Background technology
Carbon fibre rim is in use, it is necessary to could realize bicycle with cycle frame after loading onto flower-drum, spoke
Rotating function., in actual use, just must be in carbon but different flower-drum usually corresponds to different spoke hole counts
Bore upper corresponding hole in the inner ring position of fiber wheel rim.But in the position for having spoke hole, because the reason for drawing spoke, make
Carbon fibre rim must design thicker wall thickness in the position of spoke hole wheel rim not be in the case of high-tensile strength to meet spoke
It is destroyed.Because wheel rim is indefinite using the number of spoke, the moulding of existing bicycle wheel rim made of carbon fibre inner ring is all
Equally, also so that the inner ring in carbon fibre rim is designed as unified thicker wall thickness, this both wastes raw material, also so that wheel
It is heavier to enclose the weight of design, can not meet the needs of market is actual.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of integral strength high, light-weight carbon fiber wheel
Circle.
Technical solution is used by the utility model：It is a kind of that there is the carbon fibre rim with boss carbocyclic ring, including a ring
The closed chamber of shape, the side wall of the chamber are equipped with the position of foetus hole for being used for housing the inner tube of a tyre toward the direction extension away from wheel circle center
Groove, the chamber is interior to be equipped with carbocyclic ring, and the side wall of carbocyclic ring is equipped with some boss, and the boss, which is equipped with, to be used to install spoke
Spoke hole.
Further, the boss is each provided on the outer ring side wall of carbocyclic ring.
Further, the lateral cross section shape of the boss is circular, oval, square, trapezoidal or triangle.
Compared with prior art, the utility model using carbon fiber can post forming characteristic, not influencing, product is original
It on the basis of moulding, will be buried in the carbocyclic ring with boss well prepared in advance inside wheel rim, spoke hole designed at boss, its
The weight of product is greatly reduced again while the integral strength of product is improved, and is competed in the market so as to improve product
Power.
Brief description of the drawings

Fig. 2 is the utility model carbocyclic ring and wheel rim cooperation schematic diagram.
In figure：1- carbocyclic rings, 11- boss, 2- wheel rims, 21- position of foetus hole slot, 22- chambers, 3- spoke holes.
Embodiment
Embodiment below in conjunction with the accompanying drawings, is described further the utility model：
As shown in Figure 1, 2, it is a kind of that there is the carbon fibre rim 2 with 11 carbocyclic ring 1 of boss, including a cricoid closed chamber
22, the side wall of the chamber 22 is equipped with the position of foetus hole slot 21 for being used for housing the inner tube of a tyre toward the direction extension away from wheel circle center, described
Carbocyclic ring 1 is equipped with chamber 22, the outer ring side wall of carbocyclic ring 1 is equipped with some boss 11, and the boss 11, which is equipped with, to be used to install
The spoke hole 3 of spoke, adds carbocyclic ring 1 in wheel rim 2, the wall thickness of wheel rim 2 can do it is thin so that its weight can greatly reduce, carbocyclic ring 1
It is embedded in previously prepared in wheel rim 2, the quantity of 1 convex platform 11 of carbocyclic ring determines that spoke hole 3 is arranged on by actually required spoke hole 3
The intensity of spoke hole 3 can be improved on boss 11, remaining part thickness of carbocyclic ring 1 is relatively thin, can reduce its weight, so as to reduce wheel rim 2
Overall weight.
In the present embodiment, the lateral cross section shape of the boss 11 for circular, oval, square, trapezoidal, triangle or its
His arbitrary polygon.
Specifically, the production method of wheel rim 2 comprises the following steps in the present embodiment：
Step 1：A carbocyclic ring 1 for carrying boss 11 is made with particular manufacturing craft, the quantity of boss 11 is by actually required spoke
Hole 3 determines；
Step 2：By the carbocyclic ring 1 with boss 11 during pre-shaped in be embedded in wheel rim 2 the inside shape, one complete wheel rim
2, the finished product of pre-shaped process is put into 2 molding die of wheel rim, is then placed in former, molding, fills height into shaping airbag
Calm the anger body, 160 degree are molded 60 minutes；
Step 3：The wheel rim 2 of forming is removed from the molds；
Step 4：Burr removing, takes out shaping airbag, examines the flatness and out of roundness of wheel rim 2；
Step 5：Bore spoked and gas nozzle hole；
Step 6：Surface baking vanish.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real
Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Protect scope.
