Description
Technical field
The utility model relates to the shelf of the simple and easy vehicle, relates in particular to a kind of cycle frame.
Background technology
Cycle frame is the important composition parts of bicycle, popular and universal along with cycle racing, and the vehicle frame improvement never stops, and uses various materials and technology in the hope of promoting intensity and reducing weight.Lifting and mountain bike race sports requirement along with bicycle manufacturer research and development ability, mountain bike tare, intensity, life-span have also been proposed very high requirement, and the upper pipe of vehicle frame, lower pipe will bear that horizontal direction is repeatedly reciprocal draws, presses combined stress under the actual Practical Condition, as car body load, antidetonation and the center of coordinating each assembly, the weight of front triangle structure, intensity and fatigue property are the keys that determines vehicle security, stability and service life.But the vehicle frame that existing intensity is high is relatively heavier and each parts is weld togethers, and is moving defeated inconvenient.Use also very heavy.
The utility model content
For above-mentioned technological deficiency, the technical matters that the utility model need solve provides low, the detachable and high rigidity of a kind of traffic cost and lightweight vehicle frame.
For solving the problems of the technologies described above, the technical scheme that the utility model need provide is: a kind of cycle frame, whole triangular in shape, comprise head tube, seat pipe and Five-way tube, be connected by upper siphunculus between head tube and the seat pipe, seat manage and Five-way tube between by vertical siphunculus connection, be connected by lower through-tube between head tube and the Five-way tube, head tube is that interlocking is connected with the pipe of being connected and upper siphunculus, and the seat pipe is that interlocking is connected with Five-way tube and vertical siphunculus, and head tube is that interlocking is connected with Five-way tube and lower through-tube.
Further: in above-mentioned cycle frame, head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube all are that the blanked part of digital controlled lathe, especially head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube all are TC4 titanium alloy casting casting dies.Perhaps head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube all are carbon fibre resin complex plastic spares.Again or: head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube are the blanked part of digital controlled lathe and in the carbon fibre resin complex plastic spare any, and namely head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube can be that the blanked part of digital controlled lathe and the mixing of carbon fibre resin complex plastic spare are used.
Further again: in above-mentioned cycle frame, described interlocking junction is provided with standing screw, perhaps: described interlocking junction is to be threaded, further strengthened head tube, seat pipe, Five-way tube respectively with being connected of upper siphunculus, vertical siphunculus, lower through-tube.
Compared with prior art, above-mentioned cycle frame head tube is that interlocking is connected with the pipe of being connected and upper siphunculus, and the seat pipe is that interlocking is connected with Five-way tube and vertical siphunculus, and head tube is that interlocking is connected with Five-way tube and lower through-tube, so be detouchable, traffic cost is low.Head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube all are blanked parts of digital controlled lathe, CNC (numerically-controlled machine tool) is the abbreviation of computer digital control machine tool (Computer numerical control), is a kind of by programme controlled automated machine tool.This control system can logically be processed has control coding or other symbolic instruction regulated procedures, by computing machine it is deciphered, thereby the action that lathe has been put rules into practice is processed into the half-blank fabricated part by Tool in Cutting with the blank material.The precision of this lathe itself is high, rigidity is large, can select favourable machining dosage, high productivity (be generally general machine tool 3 ~ 5 times); The Machinery Tool Automation degree is high, can reduce labor intensity; Mass production, product design is easily controlled; Specialized capability to operating personal requires lower.Stamping technology refers to utilize mould sheet metal to be made various en plaque parts and housing, container class workpiece on compression machine, or pipe fitting is made various tubular workpieces.The moulding technique that this class is carried out in cold conditions is called cold stamping, is called for short punching press.Blanked part is compared with foundry goods, forging, has thin, even, light, strong characteristics.Punching press can be made the workpiece with reinforcing ribs, fluctuating or flange that additive method is difficult to make, to improve its rigidity.Because adopt precision die, workpiece accuracy can reach micron order, and repeatable accuracy is high, specification is consistent, nest, boss etc. can punching press portal.Cold-stamped part is generally no longer through cutting, or only needs a small amount of cutting.Heat-punch member precision and apparent condition are lower than cold-stamped part, but still are better than foundry goods, forging, and the cutting amount is few, and efficient is high.Especially head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube all are TC4 titanium alloy casting casting dies.TC4 titanium alloy casting casting die is so that the mechanical property of vehicle frame is good, toughness is high, and lightweight, corrosion stability are good.
Perhaps: head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube all are carbon fibre resin complex plastic spares.Carbon fibre resin complex plastic spare is a kind of new material of mechanical property excellence, and its proportion is less than 1/4 of steel, and the carbon fiber resin composite material tensile strength all more than 3500Mpa, is 7 ~ 9 times of steel generally, and tensile modulus of elasticity is that 230 ~ 430Gpa also is higher than steel.Therefore the strength-to-density ratio of CFRP is that the ratio of intensity and its density of material can reach more than the 2000Mpa/ (g/cm3), and the strength-to-density ratio of A3 steel only is about 59Mpa/ (g/cm3), and its specific modulus is also high than steel.The strength-to-density ratio of material is higher, and then member dead weight is less, and specific modulus is higher, and then the rigidity of member is larger.Again or: head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube are the blanked part of digital controlled lathe and in the carbon fibre resin complex plastic spare any, and namely head tube, seat pipe, Five-way tube, upper siphunculus, vertical siphunculus, lower through-tube can be that the blanked part of digital controlled lathe and the mixing of carbon fibre resin complex plastic spare are used.
In sum, the cycle frame of the utility model gained has detachably, convenient transportation, and can arbitrarily replace with siphunculus, vertical siphunculus, lower through-tube, reaches random change overall height or adjusting seat appearance, satisfies the people of differing heights to the operating needs of vehicle frame.Vehicle frame self has lightweight, the characteristics that intensity is high, convenient for production and cost is low, convenient recovery maintenance, recycles, and reduces resource consumption, reaches the purpose of energy-conserving and environment-protective.
