於本實施例中該第一框高11與該第二框高21的比係為60：38，比值為1.58，即該第一框高11係為60mm、該第二框高21係為38mm，該第一框高11之尺寸較該第二框高21之尺寸大可使該自行車於高速騎乘時，該前輪框1具有較佳的破風能力（如圖6所示），以降低風阻，另外該前輪框1之框高較高可使重量較重以具有較高之轉動慣性，可使該自行車滑行時之減速效果較低，而該後輪框2之框高較低可使重量較輕以具有較低之轉動慣性，騎乘者踩踏時較省力，以容易驅動該自行車。In this embodiment, the ratio of the first frame height 11 to the second frame height 21 is 60:38, and the ratio is 1.58, that is, the first frame height 11 is 60 mm, and the second frame height 21 is 38 mm. The size of the first frame height 11 is larger than the size of the second frame height 21, so that the front wheel frame 1 has better wind breaking ability (as shown in FIG. 6) when the bicycle is riding at a high speed to reduce the wind resistance. In addition, the frame height of the front wheel frame 1 is relatively high to make the weight heavier to have a higher rotational inertia, so that the deceleration effect of the bicycle when sliding is lower, and the frame height of the rear wheel frame 2 is lower. Lighter to have lower rotational inertia, the rider is less labor-saving when pedaling, to easily drive the bicycle.
該前輪框1之該二第一側壁14的最遠軸向距離定義一第一框寬16，該後輪框2之該二第二側壁24的最遠軸向距離定義一第二框寬26，該第一框寬16與該第二框寬26的比係介於28：23至23：23之間。於本實施例中該第一框寬16與該第二框寬26的比係為25：23，即該第一框寬16係為25mm、該第二框寬26係為23mm，該第一框寬16之尺寸較大可具有較大之破風效果，可降低該車架9及該後輪框2之風阻。The farthest axial distance of the two first side walls 14 of the front wheel frame 1 defines a first frame width 16, and the farthest axial distance of the two second side walls 24 of the rear wheel frame 2 defines a second frame width 26 The ratio of the first frame width 16 to the second frame width 26 is between 28:23 and 23:23. In this embodiment, the ratio of the first frame width 16 to the second frame width 26 is 25:23, that is, the first frame width 16 is 25 mm, and the second frame width 26 is 23 mm. The larger the frame width 16 can have a larger wind breaking effect, and the wind resistance of the frame 9 and the rear wheel frame 2 can be reduced.
該前輪框1另設有複數輻條17，該第一內環壁12協向於徑向穿設有複數第一穿孔18，該前輪框1以徑向截面觀之，各該輻條17係斜向於該前輪框1之徑向方向且穿過一該第一穿孔18。該第一穿孔18之徑向尺寸係大於該輻條17之徑向尺寸，以避免該輻條17與該第一穿孔18之孔緣相摩擦而磨耗及發出噪音。The front wheel frame 1 is further provided with a plurality of spokes 17, and the first inner ring wall 12 is formed with a plurality of first through holes 18 in a radial direction. The front wheel frame 1 is viewed in a radial cross section, and each of the spokes 17 is inclined. In the radial direction of the front wheel frame 1 and through the first through hole 18 . The radial dimension of the first perforation 18 is greater than the radial dimension of the spoke 17 to prevent the spoke 17 from rubbing against the edge of the first perforation 18 to cause wear and noise.
其中該二第一側壁14之間另連接有一第一隔板19，該第一隔板19係位於該第一內環壁12與該第一外環壁13之間。各該輻條17之一端係組接於該第一隔板19與該第一外環壁13其中一者，於本實施例中各該輻條17係組接於該第一隔板19，相較於習知輪框之輻條係組接於內環壁，本案之該前輪框1之該等輻條17係組接於該第一隔板19可增加該前輪框1之轉動慣性。A first partition 19 is further connected between the two first side walls 14 , and the first partition 19 is located between the first inner ring wall 12 and the first outer ring wall 13 . One end of each of the spokes 17 is assembled to one of the first partition plate 19 and the first outer ring wall 13 . In this embodiment, each of the spokes 17 is assembled to the first partition plate 19 . The spokes of the conventional wheel frame are assembled to the inner ring wall. The spokes 17 of the front wheel frame 1 of the present invention are coupled to the first partition plate 19 to increase the rotational inertia of the front wheel frame 1.
較佳地，該第一置胎面15係供一第一輪胎3設置，該第一輪胎3之管徑尺寸係等於該第一框寬16之尺寸；該第二置胎面25係供一第二輪胎4設置，該第二輪胎4之管徑尺寸係等於該第二框寬26之尺寸。可避免空氣於反向於該自行車前進方向通過該第一輪胎3與該第二輪胎4時，空氣於該前輪框1及該後輪框2產生渦流而增加風阻。Preferably, the first tread surface 15 is provided for a first tire 3, the diameter of the first tire 3 is equal to the size of the first frame width 16; and the second tread surface 25 is for a second The tire 4 is disposed such that the diameter of the second tire 4 is equal to the size of the second frame width 26. It is avoided that air passes through the first tire 3 and the second tire 4 in a direction opposite to the forward direction of the bicycle, and air is vortexed in the front wheel frame 1 and the rear wheel frame 2 to increase the wind resistance.
另外，該第一內環壁12與該第二內環壁22其中至少一者係為U型板，於本實施例中該第一內環壁12與該第二內環壁22皆為U型板，可降低橫向該自行車移動方向之風阻。In addition, at least one of the first inner ring wall 12 and the second inner ring wall 22 is a U-shaped plate. In the embodiment, the first inner ring wall 12 and the second inner ring wall 22 are both U. The stencil can reduce the wind resistance in the direction of the bicycle.
本發明另提供一種自行車，其包括一如上所述的慣性輪組，該自行車另包括一車架9，該車架9包括一前叉管91及一後叉管92，該前輪框1係樞設於該前叉管91，該後輪框2係樞設於該後叉管92，因此該自行車於高速騎乘下可有效降低風阻，且騎乘者踩踏時較省力，以容易驅動該自行車。The present invention further provides a bicycle comprising an inertia wheel set as described above, the bicycle further comprising a frame 9, the frame 9 comprising a front fork tube 91 and a rear fork tube 92, the front wheel frame 1 being pivoted The rear fork tube 91 is disposed on the rear fork tube 92. Therefore, the bicycle can effectively reduce the wind resistance under high-speed riding, and the rider is less laborious when stepping on the bicycle to easily drive the bicycle. .
綜上，本發明之慣性輪組及包括該慣性輪組之自行車，該第一框高之尺寸較該第二框高之尺寸大可使該自行車於高速騎乘時，該前輪框具有較佳的破風能力，以降低該車架與該後輪框之風阻，而該後輪框之框高較低可使重量較輕以具有較低之轉動慣性，騎乘者踩踏時較省力，以容易驅動該自行車。In summary, the inertia wheel set of the present invention and the bicycle including the same, the first frame height is larger than the second frame, and the front wheel frame is better when the bicycle is riding at a high speed. The ability to break the wind to reduce the wind resistance of the frame and the rear wheel frame, and the frame height of the rear wheel frame is lower to make the weight lighter to have lower rotational inertia, and the rider is less laborious when stepping on, so that it is easy Drive the bike.
