如圖7至圖9所示,其係本發明的第五檔的動力傳送方向示意圖,該套筒本體161的調速凸緣162未抵靠於第四離合器42的各第四棘爪422,如圖8所示,該環齒輪41旋轉時的離心力讓各第四棘爪422的一端翹起,使得各第四棘爪422卡制於該輪轂11的輪轂內齒面113,該調速套筒組16的第一棘爪164卡制於該第一行星臂34的行星棘輪面341,且調整該定位彈簧36的緊縮程度,讓該滑塊本體173的複數個卡扣凸部175與該第一太陽齒輪32的第一卡扣孔321相互卡扣,動力由該鏈條帶動該鏈盤23轉動,如圖9所示,各第二棘爪212為單向棘爪式離合器,各第二棘爪212置於該鏈盤套筒211所設置的棘爪槽內,並連結件該鏈盤套筒211與該環齒輪41,當該鏈盤套筒211的轉速小於該環齒輪41,此時該單向棘輪面411會產生一力將各第二棘爪212壓回棘爪槽內,使得該鏈盤套筒211與該環齒輪41斷開,此特性稱為超速(Overrunning)特性,使各第二棘爪212脫離該單向棘輪面411而不產生卡制效果;As shown in FIG. 7 to FIG. 9 , which is a schematic diagram of the power transmission direction of the fifth gear of the present invention, the speed control flange 162 of the sleeve body 161 does not abut against each of the fourth pawls 422 of the fourth clutch 42 . As shown in FIG. 8 , the centrifugal force when the ring gear 41 rotates causes one end of each of the fourth pawls 422 to be tilted, so that the fourth pawls 422 are clamped to the hub inner tooth surface 113 of the hub 11 . The first pawl 164 of the cartridge set 16 is engaged with the planetary ratchet surface 341 of the first planetary arm 34, and the degree of tightening of the positioning spring 36 is adjusted to allow the plurality of snap projections 175 of the slider body 173 to The first snap holes 321 of the first sun gear 32 are mutually buckled, and the power is driven by the chain to rotate the chain plate 23. As shown in FIG. 9, each of the second pawls 212 is a one-way pawl clutch, and each second The pawl 212 is disposed in the pawl groove provided by the sprocket sleeve 211, and connects the sprocket sleeve 211 and the ring gear 41. When the rotation speed of the sprocket sleeve 211 is smaller than the ring gear 41, this The one-way ratchet surface 411 generates a force to press each of the second pawls 212 back into the pawl groove, so that the sprocket sleeve 211 is disconnected from the ring gear 41. Overspeed (overrunning) characteristic, each second one-way ratchet pawl 212 is separated from the surface 411 without generating a clamping effect;
相同的,因該輪轂11的角速度大於該第三行星臂37的角速度而產生超速特性,使該第三棘爪301脫離該輪轂棘輪面115而不產生卡制效果,則該動力經由該鏈盤23傳遞至該調速套筒組16,因該第一棘爪164卡制於該行星棘輪面341,使得該調速套筒組16帶動該第一行星臂34轉動,而該第一行星臂34經由各第一行星齒輪38裝設的各樞軸帶動該第二行星臂35轉動,因該滑塊本體173與該第一太陽齒輪32相互卡扣,則該複數個第一行星齒輪38可經由該同步內齒面413帶動該環齒輪41,因各第四棘爪422卡制於該輪轂11的輪轂內齒面113,則該環齒輪41藉由各第四棘爪422帶動該輪轂11,則最終動力由該環齒輪41經由該第四離合器42傳遞至該輪轂11而輸出。Similarly, since the angular velocity of the hub 11 is greater than the angular velocity of the third planetary arm 37 to generate an overspeed characteristic, the third pawl 301 is disengaged from the hub ratchet surface 115 without causing a clamping effect, and the power is transmitted through the sprocket. 23 is transmitted to the speed control sleeve set 16 , because the first pawl 164 is engaged with the planetary ratchet surface 341 , so that the speed control sleeve set 16 drives the first planetary arm 34 to rotate, and the first planetary arm 34. The pivots of the second planetary arms 35 are driven by the pivots of the first planetary gears 38. Since the slider body 173 and the first sun gear 32 are engaged with each other, the plurality of first planetary gears 38 can be The ring gear 41 is driven by the synchronous internal tooth surface 413. Since the fourth pawls 422 are engaged with the hub inner tooth surface 113 of the hub 11, the ring gear 41 drives the hub 11 by the fourth pawls 422. Then, the final power is transmitted from the ring gear 41 to the hub 11 via the fourth clutch 42 and is output.
如圖10所示,其係本發明的第四檔的動力傳動方向示意圖,此時,該套筒本體161的調速凸緣162未抵靠於第四離合器42的各第四棘爪422,伸張該定位彈簧36使得該第一太陽齒輪32及該第二太陽齒輪33向該輸入側111移動,使得該滑塊本體173的的複數個卡扣凸部175與該第二太陽齒輪33的第二卡扣孔331相互卡扣,並維持第五檔的該套筒本體161位置,如圖8所示,該環齒輪41旋轉時的離心力讓各第四棘爪422的一端翹起,使得各第四棘爪422卡制於該輪轂11的輪轂內齒面113,且該調速套筒組16的第一棘爪164卡制於該第一行星臂34的行星棘輪面341,動力由該鏈條帶動該鏈盤23轉動,如圖9所示,因該鏈盤套筒211的轉速小於該環齒輪41而同樣產生超速特形,使各第二棘爪212脫離該單向棘輪面411而不產生卡制效果,相同的,因該輪轂11的角速度大於該第三行星臂37的角速度而產生超速特性,使該第三棘爪301脫離該輪轂棘輪面115而不產生卡制效果;As shown in FIG. 10, it is a schematic diagram of the power transmission direction of the fourth gear of the present invention. At this time, the speed regulating flange 162 of the sleeve body 161 does not abut against the fourth pawls 422 of the fourth clutch 42. Extending the positioning spring 36 causes the first sun gear 32 and the second sun gear 33 to move toward the input side 111 such that the plurality of snap protrusions 175 of the slider body 173 and the second sun gear 33 The two latching holes 331 are mutually latched and maintain the position of the sleeve body 161 of the fifth gear. As shown in FIG. 8, the centrifugal force when the ring gear 41 rotates causes one end of each of the fourth pawls 422 to be tilted, so that each The fourth pawl 422 is engaged with the hub inner tooth surface 113 of the hub 11 , and the first pawl 164 of the speed control sleeve set 16 is engaged with the planetary ratchet surface 341 of the first planetary arm 34 . The chain drives the chain plate 23 to rotate. As shown in FIG. 9, the rotation speed of the chain sleeve 211 is smaller than that of the ring gear 41, and an overspeed feature is also generated, so that the second pawls 212 are disengaged from the one-way ratchet surface 411.
