Description
本發明有關一種自行車，更特別係，有關一種可使兩側輪轂齒輪以每分鐘相同旋轉來同時旋轉的輪轂，使得左與右踏板可持續驅動之自行車，其中，一踏板軸係分成右與左部件。 The present invention relates to a bicycle, and more particularly to a bicycle that can rotate both side hub gears at the same time per minute for the same rotation, so that the left and right pedals can be continuously driven, wherein a pedal shaft is divided into right and left. component.
請即參考圖1，一自行車通常包括一使用鏈條的動力傳輸單元(100)。自行車騎士轉動踏板時，一踏板齒輪的旋轉力可透過鏈條傳輸給後輪的一輪轂齒輪，且前輪會連同後輪旋轉，使自行車向前推進。 Referring now to Figure 1, a bicycle typically includes a power transmission unit (100) that uses a chain. When the bicycle rider turns the pedal, the rotational force of a pedal gear can be transmitted to the hub gear of the rear wheel through the chain, and the front wheel rotates together with the rear wheel to advance the bicycle.
動力傳輸單元(100)現將參考圖2描述。動力傳輸單元(100)包括一整合踏板組(113)，其中，相對踏板(112)耦合至一單踏板軸(111)；一踏板齒輪(114)，其連接至踏板軸(111)；一輪轂(120)，一後輪軸經由其穿過，且連接後輪的輪輻，一輪轂齒輪(130)，其耦合至輪轂(120)；及一鏈條(140)，用於動力傳輸。同樣地，一典型自行車包括在相對側配置的兩踏板，且直接連接至一單踏板軸(111)。 The power transfer unit (100) will now be described with reference to FIG. 2. The power transmission unit (100) includes an integrated pedal set (113), wherein the opposite pedal (112) is coupled to a single pedal shaft (111); a pedal gear (114) coupled to the pedal shaft (111); a hub (120), through which a rear axle passes and connects the spokes of the rear wheel, a hub gear (130) coupled to the hub (120), and a chain (140) for power transmission. Similarly, a typical bicycle includes two pedals disposed on opposite sides and is directly coupled to a single pedal shaft (111).
圖3示意說明一傳統自行車的組裝輪轂(120)，圖4為輪轂(120)的分解透視圖，且圖5為輪轂(120)的詳細分解透視圖。 3 is a schematic exploded perspective view of a conventional bicycle, FIG. 4 is an exploded perspective view of the hub (120), and FIG. 5 is a detailed exploded perspective view of the hub (120).
請即參考圖3與4，輪轂(120)通常包括：一輪轂殼體(122)，其中，連接一後輪的輪輻，且一輪轂固定軸(121)經由其穿過；一棘輪(130)，其轉緊固定至輪轂殼體(122)的一側；及一錐形螺帽(124)，其固定輪轂殼體(122)至輪轂固定軸(121)。 Referring to Figures 3 and 4, the hub (120) generally includes a hub housing (122) in which a spoke of a rear wheel is coupled and a hub securing shaft (121) is passed therethrough; a ratchet (130) It is fastened to one side of the hub housing (122); and a conical nut (124) that secures the hub housing (122) to the hub securing shaft (121).
此外，棘輪(130)包括：一桿輪(131)，其外周圍有一桿(132)；一鏈輪(133)，其具有在內周圍形成的一稈齒輪(133a)，並咬合桿(132)作單向傳輸動力；及一鏈齒(133b)，其在外周圍形成並咬合鏈條；及一輪罩(134)，其在極輪(131)安裝在鏈輪(133)後會固定桿輪(131)與鏈輪(133)。 Further, the ratchet (130) includes: a rod wheel (131) having a rod (132) at its outer periphery; a sprocket (133) having a stalk gear (133a) formed at the inner periphery and engaging the rod (132) a unidirectional transmission power; and a sprocket (133b) that forms and engages the chain around the outer circumference; and a wheel cover (134) that secures the rod wheel after the pole wheel (131) is mounted on the sprocket (133) ( 131) with the sprocket (133).
此一傳統自行車時常會發生脫離齒輪或斷鏈現像，因此在鏈條傳輸旋轉力過程會發生故障、與能量損失。 This conventional bicycle often happens to be out of gear or broken chain, so that failure and energy loss occur in the transmission of the rotational force of the chain.
由於踏板齒輪配置在自行車的一側，所以傳統自行車在一踏板齒輪與一輪轂齒輪間存在一較長的動力傳輸路徑。因此，在旋轉力傳輸通過鏈條時，能量損失會發生。 Since the pedal gear is disposed on one side of the bicycle, the conventional bicycle has a long power transmission path between a pedal gear and a hub gear. Therefore, energy loss occurs when the rotational force is transmitted through the chain.
此外，鏈條時常與齒輪或切削分離，因此時常發生故障。 In addition, the chain is often separated from the gear or the cutting, so that malfunctions often occur.
而且，由於一對踏板耦合至一單踏板齒輪，所以一踏板軸必須配置在後輪的半徑內。 Moreover, since a pair of pedals are coupled to a single pedal gear, a pedal shaft must be disposed within the radius of the rear wheel.
本發明針對解決相關技術的問題，且本發明的一態樣是要提供自行車具有輪轂以使相對側的輪轂齒輪能每分鐘相同旋轉來同時轉動，因此可使用分成右與左部件之一踏板軸以持續驅動右與左踏板。 The present invention is directed to solving the problems of the related art, and an aspect of the present invention is to provide a bicycle having a hub such that the hub gears on the opposite side can rotate simultaneously at the same time every minute, so that the pedal shaft divided into one of the right and left members can be used. To continuously drive the right and left pedals.
根據本發明之一態樣，一自行車包括：一輪轂，可在自行車的兩側傳輸動力，其中，該輪轂包括一旋轉軸，該旋轉軸包括至少一桿(配置在外周圍)與一對輪轂齒輪(其耦合至或整個在兩側形成)；及一輪轂殼體，旋轉軸會經由其通 過，且連接一後輪的輪輻。該輪轂殼體包括一稈齒輪，其係在內周圍形成，並咬合該桿以動力傳輸，使得該對輪轂齒輪能每分鐘相同旋轉來同時轉動。 According to one aspect of the present invention, a bicycle includes: a hub for transmitting power on both sides of the bicycle, wherein the hub includes a rotating shaft including at least one rod (disposed around the outer circumference) and a pair of hub gears (which is coupled to or formed entirely on both sides); and a hub housing through which the rotating shaft passes Pass and connect the spokes of a rear wheel. The hub housing includes a stalk gear that is formed around the interior and that engages the rod for power transmission such that the pair of hub gears can rotate simultaneously at the same time every minute.
該自行車可包括：一對踏板齒輪，其配置在一車骨架的兩側；一對踏板，其耦合至該等踏板齒輪；及一對動力傳輸單元，分別傳輸該等踏板齒輪的旋轉力至輪轂齒輪。 The bicycle may include: a pair of pedal gears disposed on both sides of a frame; a pair of pedals coupled to the pedal gears; and a pair of power transmission units respectively transmitting rotational forces of the pedal gears to the hub gear.
該動力傳輸單元可包括至少一惰齒輪，其配置在該踏板齒輪與該輪轂齒輪之間。 The power transmission unit may include at least one idle gear disposed between the pedal gear and the hub gear.
該動力傳輸單元可包括一鏈條。 The power transmission unit can include a chain.
該踏板軸可配置在後輪的半徑內。 The pedal shaft can be disposed within the radius of the rear wheel.
根據本發明的示範性具體實施例，自行車包括在一後輪相對側的踏板齒輪與輪轂齒輪，且藉由轉動齒輪來驅動。 In accordance with an exemplary embodiment of the present invention, a bicycle includes a pedal gear and a hub gear on opposite sides of a rear wheel and is driven by a rotating gear.
因此，一踏板軸分成右與左部件，且配置靠近後輪，藉此改善動力傳輸效能。 Therefore, a pedal shaft is divided into right and left members, and is disposed close to the rear wheel, thereby improving power transmission performance.
特別係，由於在自行車相對側的輪轂齒輪是以每分鐘相同旋轉來同時轉動，所以即使踏板齒輪分別提供在右與左側，右與左踏板仍可持續驅動。 In particular, since the hub gears on the opposite sides of the bicycle are simultaneously rotated with the same rotation per minute, the right and left pedals can be continuously driven even if the pedal gears are provided on the right and left sides, respectively.
此外，該自行車的長度比傳統自行車更短，因此減輕重量，藉此使維護與運輸更方便。 In addition, the bicycle is shorter in length than conventional bicycles, thus reducing weight, thereby making maintenance and transportation more convenient.
現將參考附圖詳細描述本發明的示範性具體實施例。應明白，下列具體實施例只是說明，而不是以任何方式對本發明構成限制。 Exemplary embodiments of the present invention will now be described in detail with reference to the drawings. It is to be understood that the following specific examples are merely illustrative and are not intended to limit the invention.
請即參考圖6至8，根據本發明之示範性具體實施例的自行車包括一前輪、一後輪、一車骨架、一座墊、及一動力傳輸單元(1)。 6 to 8, a bicycle according to an exemplary embodiment of the present invention includes a front wheel, a rear wheel, a car skeleton, a mat, and a power transmission unit (1).
動力傳輸單元(1)包括一踏板組(10)，該踏板組包括：一對踏板(12)，分別提供給後輪的右與左側；及一對踏板齒輪(20)，其轉耦合至一踏板軸(11)；一對輪轂齒輪(30)，其固定至後輪的一中心軸(輪轂固定軸)(61)；及一對惰齒輪(40)，其每一惰齒輪配置在踏板齒輪(20)與輪轂齒輪(30)之間，使得踏板齒輪(20)與輪轂齒輪(30)可在相同方向轉動。 The power transmission unit (1) includes a pedal group (10) including: a pair of pedals (12) respectively provided to the right and left sides of the rear wheel; and a pair of pedal gears (20) coupled to one of the pedal gears a pedal shaft (11); a pair of hub gears (30) fixed to a central shaft (hub fixed shaft) (61) of the rear wheel; and a pair of idle gears (40) each of which is disposed on the pedal gear (20) Between the hub gear (30), the pedal gear (20) and the hub gear (30) are rotatable in the same direction.
惰齒輪(40)之每一者是在齒輪牙的相對側上的側壁形成。惰齒輪(40)會咬合在側壁中的對應踏板齒輪(20)、或對應輪轂齒輪(30)。側壁係提供來避免踏板齒輪(20)、惰齒輪(40)、與輪轂齒輪(30)彼此失去咬合，藉此確保其間穩定咬合。或者，雖然未在圖顯示，但側壁是在踏板齒輪與輪轂齒輪的齒輪牙的相對側上形成，而不是在惰齒輪形成，藉此提供相同的效果。 Each of the idler gears (40) is formed on a side wall on the opposite side of the gear teeth. The idler gear (40) will engage a corresponding pedal gear (20) in the side wall, or a corresponding hub gear (30). The sidewalls are provided to prevent the pedal gear (20), the idler gear (40), and the hub gear (30) from losing each other, thereby ensuring a stable engagement therebetween. Alternatively, although not shown in the figures, the side walls are formed on the opposite sides of the gear teeth of the pedal gear and the hub gear, rather than being formed in the idler gear, thereby providing the same effect.
惰齒輪(40)之每一者係固定在車骨架的中心。 Each of the idler gears (40) is fixed to the center of the vehicle frame.
隨著此構造，當推動踏板12之一時，對應的踏板齒輪(20)會轉動，且踏板齒輪(20)的旋轉力會經由惰齒輪(40)與輪轂齒輪(30)傳輸給後輪，藉此轉動後輪。 With this configuration, when one of the pedals 12 is pushed, the corresponding pedal gear (20) will rotate, and the rotational force of the pedal gear (20) will be transmitted to the rear wheel via the idler gear (40) and the hub gear (30). This turns the rear wheel.
明確地係，在此具體實施例中，踏板軸(11)(在踏板齒輪的中心)安裝在後輪的半徑內。通常知道，踏板軸(11)較靠近配置在後輪的中心，更快回應改善動力傳輸效能。根據本發明，由於踏板軸(11)分成右與左部件，所以踏板軸(11)可安裝較靠近後輪的中心。因此，動力傳輸距離會明顯減少，藉此減少動力損失。 Specifically, in this particular embodiment, the pedal shaft (11) (at the center of the pedal gear) is mounted within the radius of the rear wheel. It is generally known that the pedal shaft (11) is placed closer to the center of the rear wheel for faster response to improved power transmission performance. According to the present invention, since the pedal shaft (11) is divided into right and left members, the pedal shaft (11) can be mounted closer to the center of the rear wheel. Therefore, the power transmission distance is significantly reduced, thereby reducing power loss.
根據此具體實施例，推動右與左踏板(12)時，旋轉力會 傳輸至分別配置在自行車相對側的輪轂齒輪(30)。因此，為了要移動根據此具體實施例的自行車，對於輪轂使後輪轉動就很重要，而允許在自行車相對側的踏板(12)轉動產生的旋轉力互補工作，但不是彼此碰撞。特別係，由於輪轂齒輪(30)分別提供給後輪的左與右側，所以輪轂構造允許輪轂齒輪(30)以每分鐘相同旋轉來轉動。當兩輪轂齒輪(30)的每分鐘旋轉彼此不符時，右與左踏板(12)不會持續交替推動。例如，輪轂係構造成，當推動左踏板(12)時，允許左與右輪轂齒輪(30)以每分鐘相同旋轉來同時轉動。 According to this embodiment, when the right and left pedals (12) are pushed, the rotational force will It is transmitted to the hub gear (30) which is respectively disposed on the opposite side of the bicycle. Therefore, in order to move the bicycle according to this embodiment, it is important for the hub to rotate the rear wheel, while the rotational forces generated by the rotation of the pedals (12) on the opposite side of the bicycle are allowed to work complementarily, but not against each other. In particular, since the hub gears (30) are provided to the left and right sides of the rear wheels, respectively, the hub configuration allows the hub gears (30) to rotate with the same rotation per minute. When the rotations of the two hub gears (30) do not match each other, the right and left pedals (12) do not continue to alternately push. For example, the hub is configured to allow the left and right hub gears (30) to rotate simultaneously with the same rotation per minute when pushing the left pedal (12).
圖9為示意說明根據本發明之具體實施例的一組裝輪轂(60)；圖10為輪轂(60)的分解透視圖；及圖11為輪轂(60)的詳細分解透視圖。請即參考圖9至11，根據具體實施例的輪轂(60)包括一輪轂固定軸(61)、一輪轂殼體(63)、與一旋轉軸(62)。 Figure 9 is an exploded perspective view schematically illustrating an assembly hub (60) in accordance with an embodiment of the present invention; Figure 10 is an exploded perspective view of the hub (60); and Figure 11 is a detailed exploded perspective view of the hub (60). Referring now to Figures 9 through 11, a hub (60) according to a particular embodiment includes a hub securing shaft (61), a hub housing (63), and a rotating shaft (62).
輪轂殼體(63)包括：邊緣(63b)，其在相對側形成且連接至後輪的輪輻(50)；及一稈齒輪(63a)，其係在內周圍上形成。 The hub housing (63) includes an edge (63b) formed on the opposite side and coupled to the spokes (50) of the rear wheel; and a stalk gear (63a) formed on the inner periphery.
旋轉軸(62)係貫穿輪轂殼體(63)，且包括在外周圍提供的至少一桿(62c)。明確地係，該桿(62c)係配置在旋轉軸(62)的外周圍上形成的座槽(62b)中，且由一圓線彈簧(62d)彈性支撐從槽凸出。該桿(62c)係咬合稈齒輪(63a)以在一方向轉動該輪轂殼體(63)。 The rotating shaft (62) extends through the hub housing (63) and includes at least one rod (62c) provided at the outer periphery. Specifically, the rod (62c) is disposed in a seat groove (62b) formed on the outer periphery of the rotating shaft (62), and is elastically supported by a round wire spring (62d) to protrude from the groove. The rod (62c) is a bite stalk gear (63a) that rotates the hub shell (63) in one direction.
旋轉軸(62)包括在相對側形成的邊緣(62a)，每一邊緣係轉緊至每一輪轂齒輪(30)。因此，在後輪兩側的輪轂齒輪(30)可彼此同步轉動。此外，該對輪轂齒輪(30)可與旋轉軸(62)的相對側整個形成。 The rotating shaft (62) includes edges (62a) formed on opposite sides, each edge being fastened to each hub gear (30). Therefore, the hub gears (30) on both sides of the rear wheel can rotate in synchronization with each other. Further, the pair of hub gears (30) may be integrally formed with the opposite side of the rotating shaft (62).
當組裝旋轉軸(62)在輪轂殼體(63)時，邊緣(62a)之一係與旋轉軸(62)分開，且另一邊緣係耦合至其，藉此更容易透 過輪轂殼體(63)組裝旋轉軸(62)。 When the rotating shaft (62) is assembled in the hub shell (63), one of the edges (62a) is separated from the rotating shaft (62), and the other edge is coupled thereto, thereby making it easier to see through The rotating shaft (62) is assembled through the hub housing (63).
此外，固定在自行車骨架的輪轂固定軸(61)係插入旋轉軸(62)，且輪轂(60)更包括一錐形螺帽(64)，以固定旋轉軸(62)至輪轂固定軸(61)。 Further, a hub fixing shaft (61) fixed to the bicycle frame is inserted into the rotating shaft (62), and the hub (60) further includes a tapered nut (64) for fixing the rotating shaft (62) to the hub fixing shaft (61). ).
為了促進旋轉，軸承(B)提供在旋轉軸(62)與輪轂殼體(63)之間、及在旋轉軸(62)與錐形螺帽(64)之間。 To facilitate rotation, the bearing (B) is provided between the rotating shaft (62) and the hub housing (63), and between the rotating shaft (62) and the tapered nut (64).
請即參考圖11，為了驅動輪轂殼體(63)，耦合在輪轂齒輪(30)的旋轉軸(62)係配置在輪轂殼體(63)與輪轂固定軸(61)之間；如此，兩輪轂齒輪(30)能以每分鐘相同旋轉來同時轉動。因此，自行車右與左側的踏板齒輪亦以每分鐘相同旋轉來轉動，且在相對側的踏板(12)彼此以180度配置，藉此使自行車騎士推動踏板。 Referring to FIG. 11, in order to drive the hub housing (63), a rotating shaft (62) coupled to the hub gear (30) is disposed between the hub housing (63) and the hub fixing shaft (61); thus, two The hub gear (30) can rotate simultaneously with the same rotation per minute. Therefore, the pedal gears of the right and left sides of the bicycle are also rotated at the same rotation every minute, and the pedals (12) on the opposite sides are arranged at 180 degrees to each other, thereby causing the bicycle rider to push the pedal.
同樣地，當使用個別配置在自行車右與左側沒有鏈條的齒輪來驅動自行車時，根據本發明之具體實施例的自行車可使用較少數目齒輪作為動力傳輸效能。此外，自行車包括動力傳輸單元(1)，其具輪轂(60)，構造上能以每分鐘相同旋轉，使配置在自行車兩側的齒論轉動以驅動自行車。 Likewise, bicycles in accordance with embodiments of the present invention may use a smaller number of gears as power transmission performance when using a gear that is individually configured with no chains on the right and left sides of the bicycle to drive the bicycle. In addition, the bicycle includes a power transmission unit (1) having a hub (60) configured to rotate at the same time per minute to rotate the teeth disposed on both sides of the bicycle to drive the bicycle.
或者，複數個惰齒輪可提供。即是，奇數惰齒輪可提供，使得踏板齒輪與輪轂齒輪能以相同方向轉動。或者，偶數惰齒輪可提供，使得踏板齒輪與輪轂齒輪能以相對方向轉動，且後輪然後透過傳輸與踏板齒輪相同方向轉動。 Alternatively, a plurality of idler gears are available. That is, an odd number of idler gears can be provided so that the pedal gear and the hub gear can rotate in the same direction. Alternatively, an even number of idler gears may be provided such that the pedal and hub gears are rotatable in opposite directions and the rear wheels are then transmitted in the same direction as the pedal gears.
圖12示意說明根據本發明之另一具體實施例的自行車。相較於圖7所示的具體實施例，鏈條(70)提供作為動力傳輸單元，而不是圖7的惰齒輪(40)。根據本發明，由於踏板軸(11)分成配置在相對側的兩部件，所以踏板軸(11)可安裝較靠近後輪的中心，使得可使用較短的鏈條。 Figure 12 illustrates schematically a bicycle in accordance with another embodiment of the present invention. In contrast to the particular embodiment illustrated in Figure 7, the chain (70) is provided as a power transmission unit rather than the idler gear (40) of Figure 7. According to the present invention, since the pedal shaft (11) is divided into two members disposed on the opposite sides, the pedal shaft (11) can be mounted closer to the center of the rear wheel so that a shorter chain can be used.
