在一實施例中,該連接軸套32之外表面設有導軌結構323,且該離合器34係以一內套孔344套設於該連接軸套32的外表面,該內套孔344具有配合該連接軸套32外表面之導軌結構323的導槽結構3441。 In an embodiment, the outer surface of the connecting sleeve 32 is provided with a rail structure 323, and the clutch 34 is sleeved on the outer surface of the connecting sleeve 32. The inner sleeve hole 344 has a fit. The channel structure 3441 of the rail structure 323 connecting the outer surface of the sleeve 32.
在一實施例中,該離合器34表面具有一環向凸出的大徑,該大徑的外環面形成二錐面,該二錐面分別為該第一壓合面341及該第二壓合面342,當然,該二錐面可為平面或曲面(本實施例的錐面係為平面)。又,該第一接觸面33121、該第二接觸面3331、該第一壓合面341及一第二壓合面342係為高耐磨性、高摩擦系數之表面,以利頻繁的換檔動作下仍能維持一定的耐用性。 In one embodiment, the surface of the clutch 34 has a large diameter that protrudes in a ring shape, and the outer ring surface of the large diameter forms a biconical surface, and the biconical surface is the first pressing surface 341 and the second pressing Face 342, of course, the biconical surface can be a flat surface or a curved surface (the tapered surface of the embodiment is a flat surface). Moreover, the first contact surface 33121, the second contact surface 3331, the first pressing surface 341 and a second pressing surface 342 are surfaces with high wear resistance and high friction coefficient, so as to facilitate frequent shifting. A certain degree of durability can still be maintained under the action.
在一實施例中,在該扭力輸出軸上3341更包含一鍊輪50或一皮帶輪(未圖示)組設於其上,以利將本變速系統所輸出之二種不同的轉速(扭力),以鏈條或皮帶傳動至車輛後輪的減速齒輪(或差速器),而驅 動車輛。 In an embodiment, the torque output shaft 3341 further includes a sprocket 50 or a pulley (not shown) disposed thereon to facilitate the two different rotational speeds (torque) output by the shifting system. , driven by a chain or belt to the reduction gear (or differential) of the rear wheel of the vehicle Moving the vehicle.
