Embodiment Construction
[0020] The present invention provides a method for strengthening the structural strength of the spokes of bicycles and motorcycles. The method adopts mechanical processing to improve the structural strength of the neck 3 and the bending part 2 of the spoke 1 body; The spokes after the inventive method processing are compared and explained:
[0021] Taking the spoke body 1 made of stainless steel SS 304 by conventional technology as an example, the shear stress is about 60kgf / mm 2 , pulling force about 110kgf / mm 2 , therefore, if the wire diameter of the spoke is 2.0mm, then:
[0022] 1. The maximum tensile force that the spokes can withstand is
[0023] 110kgf / mm 2 ·[(2.0 / 2) 2 ·π]mm 2 =345kgf
[0024] 2. The maximum shear force that the spokes can withstand is (the actual spokes are not cut vertically, the section is approximately equal to 4.5~5.0)
[0025] 60kgf / mm 2 ·[4.5~5.0]mm 2 =270~300kgf
[0026] From the above calculation results, it can be seen that although...
