Abstract
一種後花轂組合,包括有花轂、直拉輻條(pulling spokes)以及彎折輻條(static spoke),主要由花轂提供直拉輻條與彎折輻條搭配安裝下,直拉輻條其固定於花轂的水平位置較彎折輻條固定花轂的水平位置更靠近花轂的中間位置,因此在花轂轉動時,直拉輻條的垂直分力大於水平分力,如此提昇了直拉輻條的張力,更藉由彎折輻條的水平方向分力大於直拉輻條的水平分力,如此彎折輻條提供了花轂橫向剛性,據以達成本創作提高扭轉與橫向剛性效用。 A rear flower hub combination includes a flower hub, a pull spokes and a static spoke, which are mainly provided by a flower hub providing a straight pull spoke and a bent spoke, and the straight pull spoke is fixed to the flower The horizontal position of the hub is closer to the middle position of the hub than the horizontal position of the fixed spoke fixing hub, so that the vertical component of the straight pull spoke is greater than the horizontal component when the hub is rotated, thus increasing the tension of the straight pull spoke, Moreover, the horizontal component of the bent spoke is greater than the horizontal component of the straight pull spoke, and thus the bent spoke provides the lateral rigidity of the hub, thereby achieving the present invention to improve the torsion and lateral rigidity.
Description
關於自行車用的後花轂,特別的是同時採用了直拉輻條與彎折輻條,以致花轂運轉時與習知產品相較之下,具有提高扭轉與橫向剛性者。 Regarding the rear flower hub for bicycles, in particular, the straight pull spokes and the bent spokes are used at the same time, so that the flower hub operates with improved torsion and lateral rigidity as compared with conventional products.
自行車的行進順暢與否,輪組是佔據相當大的關鍵因素。輪組之所以能順利轉動完全仰賴花轂與車架間的配合,特別的是輪組的轉動,是依靠連接在輪圈與花轂之間的輻條來驅動。所以透過人力持續性踩踏大盤上的踏板,而大盤同步驅動鏈條,讓鏈條拉動位於花轂一側的飛輪,藉以連動花轂持續轉動,也因輻條拉動輪圈,所以花轂與輻條之間的配合則攸關於輪組的扭轉剛性。優良的扭轉剛性可以克服自行車其輪組在彎道與崎嶇路面的受力變化。 Whether the bicycle travels smoothly or not, the wheel set is a key factor that occupies a considerable amount. The reason why the wheel can rotate smoothly depends entirely on the cooperation between the hub and the frame, in particular, the rotation of the wheel set is driven by the spokes connected between the wheel and the hub. Therefore, the manpower continuously tramples the pedal on the large plate, and the large disk synchronously drives the chain, so that the chain pulls the flywheel on the side of the flower hub, so that the flower hub continuously rotates, and the spoke pulls the rim, so the flower hub and the spoke are The fit is about the torsional rigidity of the wheel set. Excellent torsional rigidity can overcome the force variation of the bicycle's wheel set on curved and rugged roads.
目前常見的花轂編織輻條的型態大致上有輻射式或交叉式。所謂輻條採用輻射式排列方式是指輻條以花轂為中心呈輻射狀排列連接輪圈,且輻條呈等角度間隔排列。輻條交叉式是指相鄰的輻條交叉排列連接於輪圈與花轂,又交叉式排列的輻條又可因後輪驅動側位置來排列不同交叉型態。現今已知一種新型 態的自行車花轂如台灣新型專利號第M517688號,其可以提供直頭輻條、彎頭輻條兩種型式混合使用的自行車花轂。然而,此專利案除了在轂盤輻射排列多個條狀之直頭接合孔,更進一步在第二實施例與第三實施設置多個長條狀直頭側向孔係沿著轂盤,此種設計嚴重破壞了轂盤的結構強度;再者,直頭輻條與轂盤的組裝時,必須先從轂盤外側狹小內凹空間的環槽中尋找直頭接合孔位置,才能讓直頭輻條的桿身部穿設直頭接合孔,因此,此種型態在組裝上相當麻煩與不便,換言之,此種花轂結構對於業者來說相當不利於大量生產之安裝需求。 At present, the types of flower hub woven spokes are generally radiant or cross-type. The so-called spokes adopting the radiant arrangement means that the spokes are arranged in a radial arrangement around the flower hub, and the spokes are arranged at equal angular intervals. The spoke cross type means that adjacent spokes are arranged in a crosswise manner and connected to the rim and the flower hub, and the cross-arranged spokes can also arrange different cross patterns according to the position of the rear wheel drive side. A new type is known today. The bicycle hub of the state, such as Taiwan's new patent No. M517688, can provide a bicycle hub with a combination of straight spokes and elbow spokes. However, in this patent, in addition to radiating a plurality of strip-shaped straight engaging holes in the hub, it is further provided in the second embodiment and the third embodiment that a plurality of elongated straight lateral holes are arranged along the hub, The design seriously damages the structural strength of the hub; in addition, when assembling the straight spokes and the hub, it is necessary to find the position of the straight engaging hole from the ring groove of the narrow concave space on the outer side of the hub, so that the straight spokes can be made. The shaft portion is provided with a straight engaging hole, and therefore, this type is quite troublesome and inconvenient to assemble. In other words, such a flower hub structure is quite disadvantageous for the installation of mass production.

本創作採用在花盤12內表面121凸設的內凸塊123,並以內凸塊123的直拉孔125提供直拉輻條2穿設固定,如此能克服習知技術(台灣新型專利號第M517688號)其轂盤有剖設數個輻射排列之條狀直頭接合孔有破壞結構強度缺陷。而且在花盤12的內表面121凸設的內凸塊123更具有提供直拉輻條2易於穿設固定之效用,不會受到花轂1其他部位的視線或安裝時遮蔽、阻擾,藉以克服習知技術(台灣新型專利號第M517688號)須從轂盤外側狹小內凹空間的環槽中尋找直頭接合孔位置穿設直頭輻條不便利之處。 The present invention adopts an inner protrusion 123 protruding from the inner surface 121 of the disk 12, and provides a straight pull spoke 2 through the straight pull hole 125 of the inner protrusion 123, so that the conventional technology can be overcome (Taiwan New Patent No. M517688) No.) The hub has a strip of straight-shaped joint holes arranged in a plurality of radiation arrangements to have structural strength defects. Moreover, the inner protrusion 123 protruding from the inner surface 121 of the flower disk 12 has the utility of providing the straight pull spoke 2 to be easily worn and fixed, and is not obscured or blocked by the line of sight of other parts of the flower hub 1 or installed, thereby overcoming The conventional technology (Taiwan New Patent No. M517688) is inconvenient to find a straight spoke in the ring groove of the narrow concave space on the outer side of the hub.
請參閱第五圖所示,本創作花轂1提供直拉輻條2與 彎折輻條3搭配安裝下,直拉輻條2其固定花轂1的水平位置較彎折輻條3固定花轂1的水平位置更靠近花轂1的中間段11的中間位置,因此在花轂1轉動時,直拉輻條2的y方向的分力大於x方向的分力,如此提昇了直拉輻條2的張力,而藉由彎折輻條3的x方向分力大於直拉輻條2的x方向分力,如此彎折輻條3提供了花轂1橫向剛性,據以達成本創作所稱提高扭轉與橫向剛性效用。 Please refer to the fifth figure, the creation flower hub 1 provides straight pull spokes 2 and When the bending spokes 3 are mounted together, the horizontal position of the fixed flower hub 1 of the straight pull spokes 2 is closer to the middle position of the intermediate portion 11 of the flower hub 1 than the horizontal position of the fixed spokes 3 of the bending spokes 3, thus the flower hub 1 When rotating, the component force in the y direction of the straight pull spoke 2 is greater than the component force in the x direction, thus increasing the tension of the straight pull spoke 2, and the x-direction component of the bent spoke 3 is greater than the x direction of the straight pull spoke 2 The force component, such a curved spoke 3, provides the lateral rigidity of the flower hub 1, thereby achieving the effect of improving the torsional and lateral rigidity as claimed in the present invention.
除此之外,本創作可以透過調整中間段11的軸向尺寸、花盤12的厚度、內凸塊123距離花盤12的尺寸等方式,改變直拉孔125與彎折孔126相對中間段11中心位置,藉以調整後花轂的受力(扭轉與橫向剛性)。 In addition, the present invention can change the axial direction of the intermediate section 11, the thickness of the faceplate 12, the size of the inner protrusion 123 from the face of the faceplate 12, etc., and change the middle section of the straight pull hole 125 and the bend hole 126. 11 center position, in order to adjust the force of the flower hub (twist and lateral rigidity).
特別的是,碟剎輪組採用直拉式輻條時會因剎車時,其反向作用力(static spoke)會產生彎折(因為剎車力道遠大於驅動力道)。但一般框剎沒有此問題,因為框剎是針對輪框兩側進行剎車作用,所以框剎承受不到刹車反向作用力(static spoke)的力,但碟剎輪組就會。因此本案後花轂組合其正向作用力(pulling spoke)採用直拉輻條2,反向作用力(static spoke)採用彎折輻條3就可以避免應用於碟剎輪組剎車時所產生的輻條彎折現象。 In particular, when a disc brake wheel set uses a straight-pull type spoke, its static spoke will bend due to braking (because the braking force is much larger than the driving force). However, the general frame brake does not have this problem, because the frame brake is used for braking on both sides of the wheel frame, so the frame brake can not withstand the force of the static spoke, but the disc brake wheel set will. Therefore, in the case of the rear hub of the case, the pull spoke adopts the straight pull spoke 2, and the static spoke uses the bent spoke 3 to avoid the spoke bend generated when the disc brake wheel brake is applied. Folding phenomenon.
請配合參閱第六圖所示,圖中定義該花轂1以中間段11為軸心的正向轉動方向(如圖中箭頭所示)為前進方向,又該內凸塊123朝向前進方向轉動時,先由該直拉輻條2的頭端轉為桿身朝向前進方向,而該彎折輻條3則由桿身轉為頭端朝向前進方向。 Please refer to the sixth figure. The figure defines the forward rotation direction of the hub 1 with the middle section 11 as the axis (as indicated by the arrow in the figure) as the forward direction, and the inner protrusion 123 rotates toward the forward direction. At the same time, the head end of the straight pull spoke 2 is first turned to the forward direction, and the bent spoke 3 is turned from the shaft to the head end toward the forward direction.
值得一提的是,該複數內凸塊123係位於該內表面121靠近周緣位置,該複數內凸塊123與該中間段11之間形成有一環形空間127,又該環形空間127與該間隔空間124相連通。 It is to be noted that the plurality of inner bumps 123 are located near the peripheral edge of the inner surface 121, and an annular space 127 is formed between the plurality of inner bumps 123 and the intermediate portion 11, and the annular space 127 and the space are 124 is connected.
本創作尚具有另一實施例,並請配合參閱第七圖所示,該花盤12設有貫穿內表面121與外表面122之複數輔助孔128,又該複數輔助孔128係用以供複數彎折輻條3穿設,該複數輔助孔128係間隔環列於該花盤12並位於該複數直拉孔125與該複數內凸塊123排列之間。如此配合下直拉輻條2與彎折輻條3呈分等距排列於花盤12上。 The present invention has another embodiment, and as shown in the seventh figure, the disk 12 is provided with a plurality of auxiliary holes 128 extending through the inner surface 121 and the outer surface 122, and the plurality of auxiliary holes 128 are used for plural The bending spokes 3 are disposed, and the plurality of auxiliary holes 128 are spaced apart from the disk 12 and disposed between the plurality of straight holes 125 and the plurality of inner protrusions 123. In this way, the straight pull spokes 2 and the bent spokes 3 are arranged equidistantly on the face plate 12.
