Description
Technical field
The present invention relates generally to a kind of bicycle, be particularly related to a kind of bicycle wheel frame, it does not need to utilize the alloy frame interface of welded joint friction framework and is the structure of composite material bicycle wheel frame of the sandwich combined type integrative-structure of one carbon fiber-aluminum alloy-carbon fiber.
Background technology
The wheel frame of standard bicycle is by the alloy material of elongated rod shape, for example: aluminum alloy material, through special-purpose machines and tools roll extrusion brake forming, make overall appearance be circular, due to the restriction that is subject to alloy material matter physical property, can't make while making the brake forming of alloy material and there is higher wheel frame (generally speaking, the moulding of 30mm is difficult) of taking turns height (profile height).The weight of tradition wheel frame is subject to the heavier impact of its material, overall weight also and then improves, and in the end during work programme, more need the alloy frame interface at welding or interlocking alloy material both ends to make it form ring bodies, and form smooth brake lining in two sides grinding pedestal, and cause the loaded down with trivial details and inconvenient problem of production process, significantly improve its cost of manufacture in invisible.Moreover the alloy frame interface of this alloy material wheel frame easily forms stress raiser, easily fracture thus, and reduction of service life.The wheel frame that alloy material is made simultaneously, often because alloy material has certain ductility, therefore, when stressed collision, easily produces diastrophic phenomenon, the safety of impact driving.
And existing alloy material wheel frame cross section, the rigidity of its structure (stiffness) meets following relationship:
Rigidity=E value (coefficient of elasticity of alloy material, and Modulus) * I value (rotor inertia of moulding, Inertia)
Therefore existing dealer develops the made wheel frame of composite material, with driving property and the lightweight demand that adapts to road conditions and driver.Please refer to U.S. Patent number the 6th, 991, No. 298 " Composite bicycle rim with seamless braking surface " Patent Cases, the wheel frame that it is made for a kind of fibre resin plastics, it comprises that an alloy rim (metal tire receiving ring) and is positioned at the fibre resin plastics ring body (FRP body) of alloy rim inner edge, the cap bizet of the fibre resin plastics ring body top outside radial expansion in formation both sides (crown portion), form corresponding junction surface (extending leg portion) for the alloy rim chimeric, and the inner edge of fibre resin plastics ring body is provided with a plurality of for connecting, support the wheel bar (spoke) of fibre resin plastics ring body and wheel shaft flower hub, and the surface (brake surface) that utilizes alloy rim both sides is as brake lining.
And for example U.S. Patent number the 5th, 975, No. 645 " Carbon bodied bicycle rim " Patent Cases, the wheel frame that it is a kind of carbon fiber composite material, it comprises a carbon fiber body (carbon body portion) and an aluminum alloy rim section (aluminum tire engaging rim portion), and this carbon fiber body has a ring-type engagement section (circumferential rim engaging portion) and engages mutually with the inside face (radially inner surface) of this aluminum alloy rim section.
Above-mentioned Patent Case has all disclosed and a kind ofly please refer to Fig. 7 by aluminum alloy-carbon fiber combined type bicycle wheel frame, its section drawing that is general hollow structure.The rotor inertia I of hollow structure meets following relationship:
Because the carbon fiber body adopts blowing moulding, not blamed with bending by previous alloy material pledge rationality and be circular restriction, make aluminum alloy-carbon fiber combined type bicycle wheel frame to make and there is higher wheel frame of taking turns height (profile height), change by changing outer height h1, inner height h2, outer width b1 and insied width b2
The I value (rotor inertia of moulding, Inertia).And the E value of its structure meets following relationship:
E value=E-
1(coefficient of elasticity of alloy material)+E-
2(coefficient of elasticity of carbon fibre material)
Learn that by above-mentioned aluminum alloy-carbon fiber combined type bicycle wheel frame can change the E value of its structure and the rigidity (stiffness) that the I value increases structure.
Although yet the bicycle quick mount structure of this kind of aluminum alloy-carbon fiber combined type has advantages of high strength and high rigidity, but still there are many disappearances:
1. existing aluminum alloy-carbon fiber combined type bicycle wheel frame, its aluminum alloy part is still by the alloy material of elongated rod shape, through special-purpose machines and tools roll extrusion brake forming, make overall appearance be circular, and need the alloy frame interface at these alloy material both ends of welding and form ring bodies, and need to increase weld nugget in order to weld, must after processing, go and grind again, and cause the loaded down with trivial details and inconvenient problem of production process, improve its cost of manufacture, and the alloy frame interface of welding easily forms stress raiser, easily fracture thus, and reduction of service life.
2. existing aluminum alloy-carbon fiber combined type bicycle wheel frame, its aluminum alloy part need be with being welded and fixed in periphery, inside enclose and use carbon fiber hollow structure inflatable heat molded, when making aluminum alloy-carbon fiber combined type bicycle wheel frame for long descending highway section or needing the highway section of often brake, because the frequency of braking is high so that continue to make brake facing and wheel frame frictional heat, its temperature can be up to 80 degree, yet polyacrylonitrile-based carbon fibre commonly used (Polyacrylonitrile carbon fiber, be abbreviated as PAN-CF) thermal expansion coefficient be 20 ° of C of (0.5～-1.6) x10-6/k@, and the thermal expansion coefficient of aluminium is 20 ° of C of 24x10-6/k@, both thermal expansion coefficient have great gap, the thermal expansion coefficient of PAN-CF is even negative value, therefore in the frequency of brake under high situation, expand with heat and contract with cold to heavens, make peripheral aluminum alloy part because het expansion separates with interior carbon fiber structure delamination of enclosing, if not prison welding is solid, more can cause the risk of wheel frame moment disintegration, cyclist's life security is caused to great threat.
3. existing aluminum alloy-carbon fiber combined type bicycle wheel frame, it is two dissimilar materialss, and combination manufacture forms, the oxidation potential gap of aluminium and carbon fiber is very big, produce and electroplate corrosion corrosion (Galvanic Corrosion) or claim dissimilar materials corrosion corrosion (Galvanic or Dissimilar Metal Corrosion) phenomenon, make active larger aluminium accelerated corrosion.At existing aluminum alloy-carbon fiber combined type bicycle wheel frame, this phenomenon is another major cause that delamination separates.
Please refer to U.S. Patent number the 5th, 061, No. 013 " Bicycle rim and wheel " Patent Case, it has disclosed a kind of bicycle wheel frame of full carbon fiber, although that the wheel frame of full carbon fiber has is lightweight, moulding is unrestricted, can not change and can increase a lot of weight because of moulding, can after lightweight, not sacrifice too many intensity yet, so full carbon fiber frame has absolute advantage.But, brake rubber block is large more than aluminium alloy rim on the impact of carbon fiber wheel frame, the impact that the carbon fiber frame is subject to is only not hot, also has pressure, the brake rubber block design focal point of carbon fiber wheel frame special use is not being hindered the wheel frame and is not being produced heat as far as possible, this is just representing that friction coefficient is very low, and when driving speed can not fall must be more firmly go again the brake, but in fact such brake pressure than aluminium alloy rim same retardation efficiency much larger, and the wheel frame of the full carbon fiber distortion that quite easily is influenced by heat, for the rider, dangerous significantly raising at once.Moreover, the bicycle wheel frame of full carbon fiber is quite expensive, all adopt cheap aluminum alloy-carbon fiber combined type bicycle wheel frame while causing general player to practise, and just use the bicycle wheel frame of full carbon fiber in when match, the impact of price makes general masses can't enjoy the bicycle riding enjoyment that carbon fiber wheel frame brings.
