Technical field
The utility model belongs to bicycle spoke, particularly relates 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 utility model 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 disclose a kind of high-strength wheel spoke.
The utility model 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 utility model 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.
The beneficial effects of the utility model 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 utility model obtains with mould punching method, and bar cap and each enlarged diameter portion are simultaneously shaping through two mold punching presses.The utility model has the outstanding advantages significantly improving spoke intensity.
