Abstract
The invention relates to a high-strength wheel spoke which comprises a bar, a threaded portion at one end of the bar, a bending portion at the other end of the bar, a diameter enlarging portion between a neck and a bar cap and a diameter enlarging portion between the neck and the bending portion. A bar diameter enlarging portion is arranged on the joint part of the bar and the bending portion, reducing joint portions are arranged between a neck diameter enlarging portion and a bar cap and between the bar diameter enlarging portion and the bar. According to the high-strength wheel spoke, the practical problem that the joint part of the bar and the bending portion is worn most obviously and is prone to being broken in the using process of the spoke, the diameter enlarging portion is arranged on the joint part and remarkably reduces the phenomenon that breaking is caused easily due to the fact that the part is worn most obviously, and the tension intensity of the high-strength wheel spoke is obviously better than common hard steel spokes of the same specification. The high-strength wheel spoke is obtained through a die stamping method, and the bar cap and all the diameter enlarging portions are formed at the same time through stamping of two sets of dies. The high-strength wheel spoke has the advantages that the intensity of the spoke is improved remarkably.
Description
Technical field
The invention belongs to bicycle spoke, particularly relate to a kind of high-strength wheel spoke.
Background technology
Spoke is made up of the threaded portion of bar bar, bar bar one end and the bending part of the bar bar other end and bar cap, and spoke is widely used in bicycle, motor bike, three-wheel vehicle equal spoke wheel.
Spoke is divided into common spoke and special-shaped spoke by existing bicycle spoke standard, common spoke specification be set with № 12,13,14,15 4 kind, to spider materials, all size spoke each portion size with cut off intensity and all done clear stipulaties in standard.
Usually be consider according to vehicle, maximum load capacity and safety factor to determine to the selection of spoke specification.
But the spoke wheel of above-mentioned various vehicle in use disconnected bar phenomenon happens occasionally, especially the fracture that occurs of the junction of bar bar and bending part is comparatively concentrated.Learn that basic reason that above-mentioned position easily occurs to rupture is that the frictionally damage of this position and flower-drum is the most obvious through destructive vibration, tensile test.
In the patent of invention ' method of strengthening bicycle, locomotive spoke structure intensity ' of Authorization Notice No. CN100395051C, think that spoke can rupture at first at neck, therefore machine up mode is adopted to promote the neck of spoke body and the structural strength of bending part, namely neck and bending part wire diameter increase, and its ratio about increases by 1.15 times.The said neck of this patent of invention refers to the part adjusted between cap and bending part.
Foregoing invention patent increases the defect that there is the easy frictionally damage in the joint portion that can not make up bar bar and bending part and cause rupturing at spoke neck and bending part wire diameter.
Summary of the invention
The present invention increases wire diameter at spoke neck and bending part there is the technical matters that can not make up the easy frictionally damage of bar bar and joint portion, bending part and cause rupturing to solve, and discloses a kind of high-strength wheel spoke.
The present invention takes following technical scheme for achieving the above object: a kind of high-strength wheel spoke, comprise the enlarged diameter portion of bar bar, the threaded portion of bar bar one end, the bending part of the bar bar other end, neck and bar cap, neck and bending part, feature is, the joint portion of described bar bar and bending part is provided with bar shank diameter increase portion, is respectively equipped with undergauge convergence part between recess diameter increase portion and bar cap, between bar shank diameter increase portion and bar bar.
The present invention can also take following technical measures:
The diameter of bar shank diameter increase portion, recess diameter increase portion and bending part enlarged diameter portion be the 1.151--1.16 of bar shank diameter doubly.
Described bar shank diameter increase portion, recess diameter increase portion are connected with the surface smoothing of bending part enlarged diameter portion.
Described bar bar side is provided with the flat recess be spacedly distributed, and the width of flat recess is greater than the diameter of bar bar, and equally spaced flat recess is arranged at the bar bar side contrary with bar cap direction.
The both sides that described bar pole pair claims are provided with the symmetrical cambered surface that width is greater than bar shank diameter, and the height between the arc top of symmetrical cambered surface is less than bar shank diameter, and the direction, arc top of side cambered surface is consistent with bar cap direction.
The both sides that described bar pole pair claims are provided with the symmetrical plane that width is greater than bar shank diameter, and the height between symmetrical plane is less than bar shank diameter, and the vertical line direction of a side plane is consistent with bar cap direction.
Beneficial effect of the present invention and advantage are: this high-strength wheel spoke is while raising spoke neck, bending part tensile strength, taken into full account spoke in use the most obvious easy fracture of joint portion frictionally damage of bar bar and bending part practical problems and enlarged diameter portion is set in this joint portion, the setting of this enlarged diameter portion significantly improves the easy fracture phenomenon because this frictionally damage the most obviously causes.For № 14 common hard steel spoke, limit simulated experiment result is described, № 14 shank diameter 1.96mm, each enlarged diameter portion diameter 2.27mm (1.158 times), when pulling force reaches 3980N (kgf), the enlarged diameter portion of bar bar and bending part joint portion ruptures, its tension intensity of the spoke of same specification is obviously better than general hard steel spoke, and the limit simulated experiment result of other each specification common hard steel bicycle spoke and motor bike spoke is similar.The present invention obtains with mould punching method, and bar cap and each enlarged diameter portion are simultaneously shaping through two mold punching presses.The present invention has the outstanding advantages significantly improving spoke intensity.
