Abstract
The utility model discloses a bicycle frame claw structure, in particular to a claw part which is connected and arranged at the combination location between the tail ends of a back bicycle fork and a horizontal bicycle tube and a wheel hub; the claw part is formed by a compound material; a surface layer of carbon fiber is coated on the periphery of the claw part; and a reinforcing plate is arranged on the combined contact surface of the claw part and the wheel hub. The structure intensity is large; the bearing force is high and the service life of the bicycle can be prolonged.
Description
Technical field
The utility model relates to bicycle rack, refers in particular to a kind of pawl that colludes that is connected to front and rear fork and car transverse tube end.
Background technology
Common cycle frame, in order to increase road speed, need alleviate vehicle frame weight, therefore utilize fine material light weight of carbon and external form that the advantage of texture is arranged, with the fine material manufacturing of carbon, but collude the claw position at the rear fork of vehicle frame and car transverse tube end, it is wheel hub winding with wheel, be used for all load-carryings on the support frame, and bear the antagonistic force that wheel rim rotates on ground, must possess sizable intensity so collude claw position itself, the function that carrying can be provided and support, yet with the fine material of carbon make to collude the pawl quality more crisp, be easy to just produce embrittlement, have phenomenon of rupture to produce, just jeopardize wheel with its winding and whether can rotate and drive bicycle very restfully and advance in case collude pawl, so often cause shorten the service life of bicycle, influence the upgrading of industry.
The utility model content
The purpose of this utility model is to provide a kind of vehicle frame to collude the pawl structure, and its intensity is big, and bearing capacity is strong, can prolong the service life of bicycle.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of vehicle frame colludes the pawl structure, refer in particular to connect the end that is located at bicycle back fork and car transverse tube and wheel nave winding place collude the claw position, this colludes the claw position and constitutes with composite material, and its peripheral part coats a carbon fiber top layer, also is provided with a reinforcing chip at the contact surface place of colluding claw position and wheel nave winding.
Above-mentioned composite material aluminium alloy.
The above-mentioned body that colludes the claw position is "? " shape hook shape, and reinforcing chip is located at the open end that colludes the claw position is for being " c " iron plate of shape.
After adopting said structure, the preferable composite material of the utility model working strength is made and is colluded the claw position, replace the fine material of the hard crisp carbon of quality in the prior art, quality influence to whole vehicle body is little, also has bigger intensity, improve and collude the bearing capacity of claw position, increase support, prolong the service life of bicycle the suffered ground reaction force desired structure of wheel to integral body and load-carrying; In addition, on the peripheral part carbon coated fiber top layer of colluding the claw position, bicycle back fork and the car transverse tube made with same use carbon fiber material cooperatively interact, and whole consistent, good looking appearance has preferable texture, promotes the high-quality sense of cycle frame single-piece; Moreover, also have additional reinforcing chip at the contact surface place of colluding claw position and wheel nave winding, reduce wheel nave and driven the loss that is produced with the contact surface friction of colluding claw position 11 when rotating, make and collude the claw position and have resistance to abrasion by wheel, increase and collude the support strength of claw position, promote industrial upgrading.
Description of drawings
Fig. 1 is the three-dimensional appearance scheme drawing that the utility model embodiment bicycle back fork and car transverse tube end collude the claw position;
Fig. 2 is the plan sketch of Fig. 1;
Fig. 3 is the A-A cross-sectional schematic of Fig. 2.
The main element nomenclature
1 bicycle back fork, 2 car transverse tubes 11 collude the claw position
12 open ends, 13 carbon fiber top layers, 14 reinforcing chips
10 vehicle frames collude the pawl structure
The specific embodiment
As shown in Figure 1, it is the schematic appearance that the utility model vehicle frame colludes pawl structure 10, special finger be located at bicycle back fork 1 with the end of 2 liang of members of car transverse tube with the winding of wheel nave (not shown) collude claw position 11, it is made with composite material, body is "? " the hook shape of shape, the wheel shaft two ends (not shown) that utilizes open end 12 to collude to hold wheel nave, here the structure of bicycle back fork 1, car transverse tube 2 and wheel nave all is known technologies, neither principal character of the present utility model position, do not repeat them here.
In the present embodiment, collude be "? " in the claw position 11 the body of shape hook shape is made with the aluminum alloy of composite material, and integrally manufactured by mould.Also be coated with a carbon fiber top layer 13 at the peripheral part that colludes claw position 11, with reference to Fig. 1 and shown in Figure 2, so that it cooperatively interacts with the bicycle back fork 1 and the car transverse tube 2 that use the carbon fiber material to make, generally speaking, aesthetic property with profile unanimity, give preferable texture impression simultaneously, promote the high-quality sense of cycle frame single-piece.In addition, though composite material is heavier than the fine material of carbon commonly used now, but the utility model is only colluding claw position 11 use composite materials, therefore little to the total weight influence of unitized frame, on the contrary because aluminum alloy itself has preferable intensity, can improve the bearing capacity that colludes 11 pairs of vehicle frame integral body in claw position and load-carrying, increase is to the support of the suffered ground reaction force desired structure of wheel, avoid in the prior art using the fine material of carbon makes collude pawl because intensity own a little less than, and be easy to generate embrittlement, cause the defective of the shortening in service life of bicycle.
Cooperate shown in Figure 3 again, the contact surface place of present embodiment when open end 12 that colludes claw position 11 and wheel nave winding, also be equipped with an iron reinforcing chip 14, its profile probably is " c " shape, the loss that is produced with the contact surface friction of colluding claw position 11 in the time of can reducing wheel nave by wheel drive rotation, make and collude claw position 11 and have resistance to abrasion, increase and collude the support strength of claw position, except promoting vehicle frame single-piece structural strength, can also prolong the service life of bicycle, promote industrial upgrading.
