Description
本發明提供一種後花轂棘輪筒結構改良，其是與車輪的輪轂結構有關。 The present invention provides a rear structural ratchet ratchet structure improvement that is related to the hub structure of the wheel.
一般的後花轂10之結構組態如圖1所示，主要包含一花轂殼11組配一棘輪組12及一心軸13，該棘輪組12包含一棘輪筒121與一固定螺栓122，該棘輪筒121透過該固定螺栓122固定於該花轂殼11上，其中，該棘輪筒121的一端具有一裝配口123，該棘輪桶121內面接鄰該裝配口123處成形一擋階124；而該固定螺栓122的一端成形一凸環125，另一端成形一外螺紋部126，且該固定螺栓122上更由設置該凸環125的一端設置複數開縫127，據此，該固定螺栓122設置凸環125的一端由該裝配口123穿入該棘輪筒121內，該固定螺栓122穿入該棘輪筒121的過程中，各該開縫127受該裝配口123的迫抵而使該固定螺栓122產生些許變形量而能順利通過該棘輪筒121的裝配口123，該固定螺栓122通過該棘輪筒121的裝配口123後，該固定螺栓122失去該裝配口123迫抵的力量而能復位並限卡於該擋階124，據此使該固定螺栓122定位於該棘輪筒121上；而該棘輪筒121與該固定螺栓122組配後，該棘輪組12再透過該固定螺栓122的外螺紋部126鎖結於該花轂殼11，且該心軸13亦穿過該棘 輪組12及該花轂殼11鎖設定位，完成後花轂的組裝；由上述可知，該棘輪組12的棘輪筒121必須透過該固定螺栓122以固定於該花轂殼11上，而該固定螺栓122的凸環125、外螺紋部126及開縫127均攸關裝配時之順暢與否、裝配難易度以及裝配後之定位確實性，只要該固定螺栓122上的凸環125、外螺紋部126或該開縫127的尺寸產生誤差，就很有可能產生裝配困難或定位不確實之狀況；故生產該固定螺栓122的尺寸精度要求極高，然而，該固定螺栓122的生產方式主要是先透過模造方式成形主體，接著再二次加工成形該外螺紋部126、該些開縫127或該凸環125，在大量模造成形主體的過程中產生尺寸的累積誤差將造成尺寸精度難以掌控之缺陷；而二次加工成形該外螺紋部126、該些開縫127或該凸環125亦有一定的精度要求而需配合特殊刀具或加工流程，如此又造成加工難度高、費時及生產成本高之缺失；有鑑於此，本發明人潛心研究並更深入構思，歷經多次研發試作後，終於發明出一種後花轂棘輪筒結構改良。 The structure of the rear flower hub 10 is as shown in FIG. 1 , which mainly includes a hub shell 11 and a ratchet set 12 and a spindle 13 . The ratchet set 12 includes a ratchet cylinder 121 and a fixing bolt 122 . The ratchet cylinder 121 is fixed to the hub shell 11 through the fixing bolts 122. The ratchet cylinder 121 has a mounting opening 123 at one end thereof, and a step 124 is formed on the inner surface of the ratchet barrel 121 adjacent to the mounting opening 123; One end of the fixing bolt 122 is formed with a convex ring 125, and the other end is formed with an external thread portion 126. The fixing bolt 122 is further provided with a plurality of slits 127 at one end of the fixing bolt 125. Accordingly, the fixing bolt 122 is disposed. One end of the protruding ring 125 is inserted into the ratchet cylinder 121 through the mounting opening 123. During the process of the fixing bolt 122 penetrating the ratchet cylinder 121, each of the slits 127 is pressed by the mounting opening 123 to fix the fixing bolt. 122, a slight deformation amount can be smoothly passed through the assembly opening 123 of the ratchet cylinder 121. After the fixing bolt 122 passes through the assembly opening 123 of the ratchet cylinder 121, the fixing bolt 122 loses the force of the assembly opening 123 and can be reset and Limiting the card to the step 124, thereby fixing the fixing bolt 122 Positioned on the ratchet cylinder 121; after the ratchet cylinder 121 is assembled with the fixing bolt 122, the ratchet set 12 is further locked to the hub shell 11 through the external thread portion 126 of the fixing bolt 122, and the spindle 13 also passes through the spine The wheel set 12 and the hub shell 11 are locked in position, and the assembly of the flower hub is completed. As can be seen from the above, the ratchet cylinder 121 of the ratchet set 12 must be fixed to the hub shell 11 through the fixing bolt 122. The convex ring 125, the external thread portion 126 and the slit 127 of the fixing bolt 122 are all smooth in assembly, ease of assembly, and positioning accuracy after assembly, as long as the convex ring 125 and the external thread on the fixing bolt 122 are provided. The size of the portion 126 or the slit 127 is in an error, which is likely to cause difficulty in assembly or inaccurate positioning; therefore, the dimensional accuracy of the production of the fixing bolt 122 is extremely high, however, the production method of the fixing bolt 122 is mainly Firstly, the main body is formed by molding, and then the externally threaded portion 126, the slits 127 or the convex ring 125 are formed by secondary processing, and the cumulative error of the size during the process of forming a large number of molds causes the dimensional precision to be difficult to control. Defects; and the secondary machining forming of the external thread portion 126, the slits 127 or the convex ring 125 also have certain precision requirements and need to be matched with special tools or machining processes, which makes the processing difficult and expensive. The high production cost and the deletion; In view of this, the present inventors have intensive studies and deeper concept, after the test for multiple development, and finally invented an improved bicycle hub ratchet tubular structure latter.

以上為本發明後花轂棘輪筒結構改良之結構組態及特徵，本發明主要透過該環墊件50及該端塞60將該鎖定件40結合於該筒體30，該筒體30再透過該鎖定件40的該外螺紋部42結合於該花轂殼20，因此該鎖定件40 與筒體30的結合穩定性係直接攸關整體花轂的結構穩定性，而由於本發明之鎖定件40又是透過該環墊件50與該端塞60與該筒體30結合，該環墊件50提供些微形變能力以穿套該鎖定件40並限止於筒體30內，該端塞60則再提供另一層的迫抵限止並同時達到防塵效果，而該鎖定件40本身則能與花轂殼20的內螺紋部211結合；透過該鎖定件40與該環墊件50、端塞60的配合提供結合之訴求，如此，攸關鎖定件40與筒體30結合穩定性之尺寸精度要求分散於環墊件50與該端塞60，鎖定件40本身則只需注意與內螺紋部211配合之外螺紋部42的精度要求，該環墊件50、該端塞60與該鎖定件40均只需著重於其本身訴求的尺寸要求，各構件可分別製造、生產，並分別著重於其所需精度要求，據以降低各構件分別的製造難度，進而提高生產效率；同時，由於該環墊件50是確保該鎖定件40限止於筒體30內的重要部件，該環墊件50的結構需求是著重於具有些微形變之能力，也因如此，由於該環墊件50是透過些許形變能力而限止於該筒體30內，該環墊件50的尺寸精度是位於一個區間內而非一個單一尺寸精度，只要在該環墊件50的形變範圍尺寸區間內可限止於該筒體30內即可順利完成組裝，因此該環墊件50的尺寸容許量較大，而能降低生產難度，提高生產效率；再者，由於該鎖定件40是配合該環墊件50與該端塞60結合於該筒體30，使用一段時間後如果有上揭構件的損壞時，可單獨更換損壞之構件，而不需更換上揭所有構件，據此則又能降低保養維護之使用成本，提高附加價值。 The above is a structural configuration and a feature of the improved ratchet hub structure of the present invention. The present invention mainly couples the locking member 40 to the cylinder 30 through the ring pad 50 and the end plug 60, and the cylinder 30 is re-transmitted. The external thread portion 42 of the locking member 40 is coupled to the hub shell 20, so the locking member 40 The combined stability with the barrel 30 directly relates to the structural stability of the integral hub, and since the locking member 40 of the present invention is coupled to the barrel 30 through the ring member 50 and the end plug 60, the ring The pad member 50 provides some micro-deformation ability to pass through the locking member 40 and is limited to the inside of the barrel 30. The end plug 60 provides another layer of impingement limit and at the same time achieves a dustproof effect, and the locking member 40 itself can The internal thread portion 211 of the hub shell 20 is coupled; the cooperation of the locking member 40 with the ring cushion member 50 and the end plug 60 provides a combination of the requirements, so that the dimensional accuracy of the joint locking member 40 and the barrel 30 is stable. It is required to be dispersed in the ring cushion member 50 and the end plug 60. The locking member 40 itself only needs to pay attention to the precision requirement of the threaded portion 42 in cooperation with the internal thread portion 211, the ring cushion member 50, the end plug 60 and the locking member. 40 only need to focus on the size requirements of its own requirements, each component can be separately manufactured and produced, and each focus on its required precision requirements, so as to reduce the manufacturing difficulty of each component, thereby improving production efficiency; The cushion member 50 ensures that the locking member 40 is limited to the cylinder The important component of the ring member 50, the structural requirement of the ring cushion member 50 is to focus on the ability to have some micro-deformation, and as such, since the ring-pad member 50 is limited to the inside of the barrel 30 by a slight deformation capability, the ring pad The dimensional accuracy of the member 50 is within a range rather than a single dimensional accuracy, so that the assembly can be smoothly completed within the range of the deformation range of the ring cushion member 50, so that the cushion member 50 can be successfully assembled. The size tolerance is large, and the production difficulty is reduced, and the production efficiency is improved. Moreover, since the locking member 40 is engaged with the ring pad 50 and the end plug 60 is coupled to the barrel 30, if there is a period of use, When the component is damaged, the damaged component can be replaced separately without replacing all the components, thereby reducing the maintenance cost and increasing the added value.
