Abstract
Description
本發明係有關於一種自行車的技術領域,尤指一種皮帶用之後花鼓結構。 The invention relates to the technical field of a bicycle, in particular to a rear hub structure for a belt.
一般自行車的皮帶用之花鼓係包含一本體、一齒環、一塔基以及一皮帶輪的組合。其中該塔基的一端配置有複數棘齒元件。該齒環安裝於該本體一端內部。該塔基的一端安裝於該本體一端且該棘齒元件嚙合該齒環。如此該塔基轉動,可利用該棘齒元件帶動該齒環與該本體的組合產生轉動。 Generally, the hub system for the belt of the bicycle includes a body, a gear ring, a freewheel base and a combination of a pulley. One end of the tower base is provided with a plurality of ratchet elements. The gear ring is installed inside one end of the body. One end of the freewheel base is mounted on one end of the body and the ratchet element engages the toothed ring. In this way, the freewheel base rotates, and the ratchet element can be used to drive the combination of the toothed ring and the main body to rotate.
傳統的結構形式係塔基藉外表面的凹凸肋條與該皮帶輪軸向穿孔內壁面的凹凸肋條互相嵌合連接。由於塔基為金屬材質,皮帶輪為塑膠材質,故彼此的硬度不同。在傳遞扭矩的期間,該皮帶輪與該塔基的嵌合位置容易因材質硬度不同而產生磨損,如此一來,磨損的皮帶輪與塔基的嚙合度降低,致使皮帶輪會相對該塔基產生鬆動狀,進而在傳遞扭矩過程,會造成扭矩的傳遞不穩定及傳遞不及時的缺點,以及該輪轂整體受力不均的缺點。 The traditional structural form is that the freewheel body is connected with each other by means of the concave-convex rib on the outer surface and the concave-convex rib on the axially perforated inner wall surface of the pulley. Since the freewheel is made of metal and the pulley is made of plastic, the hardness of each is different. During the torque transmission period, the fitting position of the pulley and the freewheel body is easily worn due to the different hardness of the material. As a result, the meshing degree of the worn pulley and the freewheel body is reduced, so that the pulley will be loose relative to the freewheel body. , and then in the process of torque transmission, it will cause the shortcomings of unstable torque transmission and untimely transmission, as well as the disadvantage of uneven stress on the wheel as a whole.
本發明的目的在於提供一種皮帶用之後花鼓結構,其採用一皮帶輪配置在一本體一端的形式,使該皮帶輪所提供的驅動力,直接傳遞至該棘輪 機構,進而帶動該本體轉動,使該輪轂轉動時具有較均勻的受力效果,以及轉動時具有較佳的穩定性,藉此解決傳統輪轂整體受力不均的缺點。 The purpose of the present invention is to provide a rear hub structure for a belt, which adopts the form that a pulley is arranged at one end of the main body, so that the driving force provided by the pulley is directly transmitted to the ratchet.
