The first rolling element 201 is disposed in the slot 2321. The outer diameter of the first rolling element 201 is smaller than the inner diameter of the slot 2321. The central hole of the first rolling element 201 is threaded through a transmission shaft 202, and the other side of the transmission shaft 202 is coupled to a first power output base 304. The first power take-off base 304 is a disk-shaped body having a one-way clutch structure, and is coaxially wound around the center shaft 25. The movable eccentric ring 2211 is disposed on the inner edge wall of the second rolling element 2011 in the inner hole of the multi-slot floating driving disk 232. Therefore, the slot 2321 of the multi-slot floating driving disk 232 is opposite to the first power output base 304. The drive shaft 202 and the first rolling element 201 are floatingly displaced to change the different eccentric radius actuations of the multi-slot floating drive disk 232. Please refer to the third drawing: a schematic cross-sectional view of a power transmission part of a shifting system, which is a schematic cross-sectional view of a one-way clutch structure according to a preferred embodiment of the present invention. The other side of the drive shaft 202 of the first rolling element 201 is inserted into the shaft hole 250 of the outer edge of the first power output base 304. A central shaft 25 of an electric motor is bored in the central bore of the electric motor 22 and the stepless shifting system 23.

The one-way clutch structure 500 includes a plurality of second shaped slots 4031, a fourth rolling element 510, a fourth elastic element 520, and a shaped housing 505. This is a conventional clutch structure and will not be described again. The purpose is to make the first power output base 304 only for one-way clutching turn. In order to facilitate assembly and enlarge the contact surface of the one-way clutch structure, a hollow sleeve 350 is inserted between the second one-way clutch structure 500 and the central shaft 25, and then the hollow sleeve 350 is inserted into the central shaft 25 and fixed. On the central axis 25. Of course, the second one-way clutch structure 500 can also be directly inserted into the central shaft 25, and the second one-way clutch structure 500 can be an equivalent of a one-way clutch function, such as a one-way bearing, a one-way ratchet, and an overrunning clutch mechanism.
藉由上述的結構。當電動機22的動力輸出部221輸出動力時，視動力輸出之實際欲帶動的外部荷重大小、扭力需求、速度快慢的條件，而造成多槽孔浮動帶動盤232中央孔中的活動偏心環2211因不同受力而相對於電動機22的動力輸出部221作上下浮動位移，改變多槽孔浮動帶動盤232的槽孔2321以不同半徑變化作偏心卡塞於第一動力輸出座304的傳動軸202所穿設的第一滾動元件201之外側，以單向繞行於動力輸出部221。活動偏心環2211受力大時，多槽孔浮動帶動盤232的偏心度較小，輸出扭力較大，速度較慢。受力較小時偏心度較大，輸出扭力較小，速度較快。而此時多槽孔浮動帶動盤232上下浮動的同時也以槽孔2321的內緣推壓著第一滾動元件201外側與第一動力輸出座304同時繞行於中心軸25的軸心線。藉由第一滾動元件201的傳動軸202同時帶動第一動力輸出座304以間歇擺線運動繞行於中心軸25的軸心線旋轉，亦藉由具 單向離合結構的第一動力輸出座304作為無段變速電動機的最終動力輸出源，來聯結於需要變速的各類電動機所應用的不同產品上，以改善慣用的傳統電動機只有單速運行的缺失。With the above structure. When the power output portion 221 of the motor 22 outputs power, depending on the actual load magnitude, the torque demand, and the speed of the actual power output, the movable eccentric ring 2211 in the central hole of the multi-slot floating drive disk 232 is caused by Differently, the upper and lower floating displacements of the power output portion 221 of the motor 22 are changed, and the slot 2321 of the multi-slot floating driving plate 232 is changed to be eccentrically locked to the transmission shaft 202 of the first power output base 304 with different radius changes. The outer side of the first rolling element 201 that is worn is bypassed to the power output portion 221 in one direction. When the movable eccentric ring 2211 is subjected to a large force, the eccentricity of the multi-slot floating driving disk 232 is small, the output torque is large, and the speed is slow. When the force is small, the eccentricity is large, the output torque is small, and the speed is fast. At this time, the multi-slot floating driving disk 232 floats up and down, and also pushes the outer edge of the first rolling element 201 and the first power output base 304 around the axis line of the central axis 25 at the same time as the inner edge of the slot 2321. The driving shaft 202 of the first rolling element 201 simultaneously drives the first power output base 304 to rotate around the axis of the central axis 25 by intermittent cycloidal motion, also by The first power take-off seat 304 of the one-way clutch structure is used as the final power output source of the stepless variable speed motor to be coupled to different products applied to various types of motors that require shifting, so as to improve the lack of single speed operation of the conventional conventional motor. .
上述較佳實施例只作為敘述本發明的作動原理，舉凡利用此原理作零件等同置換，皆不脫離本發明的範疇。如本發明所述的單向離合器可為單向棘輪、單向軸承、超越式離合器等效物。彈性元件可為彈簧、鋼片、橡膠、石油製品如PU等具彈性的等效物。滾動元件如自潤軸承、軸套、滾珠、滾柱等效物。The above-described preferred embodiments are merely illustrative of the principles of operation of the present invention, and the use of this principle for equivalent replacement of components does not depart from the scope of the present invention. The one-way clutch of the present invention may be a one-way ratchet, a one-way bearing, an overrunning clutch equivalent. The elastic element can be a resilient equivalent of a spring, steel sheet, rubber, petroleum product such as PU. Rolling elements such as self-lubricating bearings, bushings, balls, rollers are equivalent.
又依上述作動原理，活動偏心環2211受力大時，多槽孔浮動帶動盤232的偏心度較小，輸出扭力較大，受力較小偏心度較大，輸出扭力較小。理論上偏心度接近零時，扭力無限大，電動機22的輸出動力幾乎接近被強壓住，啟動效率極低，不符合實際用途，解決方式可以在第一彈性元件203上設一限縮結構204，如在第一彈性元件203中置放一軸柱或U型狀等效物，使多槽孔浮動帶動盤232的偏心度大於零，則電動機22的效率不致於太低。According to the above operation principle, when the movable eccentric ring 2211 is subjected to a large force, the eccentricity of the multi-slot floating driving disk 232 is small, the output torque is large, the force is small, the eccentricity is large, and the output torque is small. Theoretically, when the eccentricity is close to zero, the torque is infinite, the output power of the motor 22 is almost close to being strongly pressed, and the starting efficiency is extremely low, which is not in practical use. The solution can be provided with a limiting structure 204 on the first elastic member 203. If a shaft column or U-shaped equivalent is placed in the first elastic member 203 so that the eccentricity of the multi-slot floating driving disk 232 is greater than zero, the efficiency of the motor 22 is not too low.

為進一步提升產品的應用，前述無段變速系統23的單向第一動力輸出座304與欲帶動的第一動力輸出外環400之間設置一第一單向離合機構300，敬請參閱第三圖：變速系統動力輸出部剖面示意圖，其系在第一動力輸出座304與第一動力輸出外環 400之間設置一第一單向離合機構300。第一單向離合機構300包括一第一異形槽403、一第三滾動元件310、一第二彈性元件320。此亦為慣用的單向離合機構，其功能為使第一動力輸出外環400作單向離合旋轉，進而帶動聯結物或輪圈電動機的輪殼21作單向離合旋轉。In order to further enhance the application of the product, a first one-way clutch mechanism 300 is disposed between the one-way first power output base 304 of the stepless speed change system 23 and the first power output outer ring 400 to be driven, please refer to the third. Figure: Schematic diagram of the power output of the shifting system, which is attached to the first power take-off 304 and the first power output outer ring. A first one-way clutch mechanism 300 is disposed between the 400s. The first one-way clutch mechanism 300 includes a first profiled groove 403, a third rolling element 310, and a second elastic element 320. This is also a conventional one-way clutch mechanism, which functions to make the first power output outer ring 400 rotate in a one-way clutch, thereby driving the wheel housing 21 of the coupling or the rim motor to perform one-way clutch rotation.
再更進一步能讓聯結物或輪圈電動機可以輕易的讓第一動力輸出座304與第一動力輸出外環400的第一單向離合機構300脫離卡合，以方便無動力時的後退轉動。於第一單向離合結構300的第一異形槽403適當處插設一撥杆620，敬請同時參閱第五圖：系一撥杆結構剖面示意圖、第六A圖、第六B圖離合器脫離前、後結構剖面示意圖。第六A圖及第六B圖其系包括單向第一動力輸出座304、第一動力輸出外環400、第三滾動元件310及第二彈性元件320及撥杆620容置在單向第一動力輸出座304的第一異形槽403與第一動力輸出外環400之間。撥杆620固接在撥杆座610上，撥杆座610的中央孔中容置一第三單向離合機構600，固定在一中空軸套350上。插設在第一異形槽403中的撥杆620只能作單向旋轉而不能後退。撥杆620插設在第一異形槽403中，插置於第三滾動元件310之一側，當電動機22動力輸出而傳動單向第一動力輸出座304時，如箭頭方嚮往前轉動，推擠第三滾動元件 310往第一異形槽403狹窄處卡塞而同時帶動第一動力輸出外環400往前轉動。因單向第一動力輸出座304亦只作單向作動，只能往前轉動，但當第一動力輸出外環400受第一動力輸出座304帶動往前轉動，如果第一動力輸出外環400的往前轉動的速度快於單向動力輸出座的速度時，第三滾動元件310則被其帶動推往第一異形槽403較寬處，達成脫離效果。此為習知的單向離合機構作動原理。然而若第一動力輸出外環400想要後退時就非常困難，因被第三滾動元件310所卡塞住。此時的撥杆620就能發揮脫離的功能。撥杆620受第三單向離合機構600的單向限制只能往箭頭方向位移，亦即第一動力輸出座304旋轉時，會同時帶著撥杆620往箭頭方向旋轉。當電動機22停止動力輸出時，第一動力輸出座304亦在停止狀態，插設於第三滾動元件310一側的撥杆620亦為靜止狀態，此時若將第一動力輸出外環400以外力向箭頭反方向往後推動，此時的第三滾動元件310受第一動力輸出環400拖動而碰觸到不動的撥杆620而往第一異形槽403較寬闊的地方位移。如第六B圖的位移狀態而使第一動力輸出座304與第一動力輸出外環400完全脫離。此時第一動力輸出外環400就可如箭頭方向自由的後轉或前移而達到與單向第一動力輸出座304完全脫離的目的。例如在電動車要後退時輪殼21能與無段變速 的傳動系統如第一動力輸出外環400脫離而無阻力時，將非常的省力、省電的實用性。Further, the coupling or the rim motor can easily disengage the first power output base 304 from the first one-way clutch mechanism 300 of the first power output outer ring 400 to facilitate the reverse rotation when there is no power. A lever 620 is inserted into the first shaped slot 403 of the first one-way clutch structure 300. Please refer to the fifth figure at the same time: a schematic diagram of a lever structure, a sixth axle, and a sixth clutch Schematic diagram of the front and rear structural sections. 6A and 6B include a unidirectional first power output base 304, a first power output outer ring 400, a third rolling element 310 and a second elastic element 320, and a lever 620 housed in a one-way A first shaped slot 403 of a power take-off base 304 is coupled to the first power take-off outer ring 400. The lever 620 is fixed to the lever base 610. A third one-way clutch mechanism 600 is received in the central hole of the lever base 610 and fixed on a hollow sleeve 350. The lever 620 inserted in the first profiled slot 403 can only be rotated in one direction and cannot be retracted. The lever 620 is inserted into the first shaped slot 403 and inserted into one side of the third rolling element 310. When the motor 22 is powered and driven to drive the one-way first power output base 304, the arrow is turned forward and pushed. Squeezing the third rolling element 310 is jammed to the narrow portion of the first profiled groove 403 while driving the first power output outer ring 400 to rotate forward. Since the one-way first power output base 304 is only operated in one direction, it can only rotate forward, but when the first power output outer ring 400 is driven forward by the first power output seat 304, if the first power output outer ring When the forward rotation speed of the 400 is faster than the speed of the one-way power output seat, the third rolling element 310 is pushed by the third rolling element 310 to the wider portion of the first shaped groove 403 to achieve the disengaging effect. This is the principle of the conventional one-way clutch mechanism. However, it is very difficult if the first power output outer ring 400 wants to retreat because it is jammed by the third rolling element 310. At this time, the lever 620 can function as a disengagement. The lever 620 can only be displaced in the direction of the arrow by the one-way restriction of the third one-way clutch mechanism 600, that is, when the first power output base 304 rotates, the lever 620 is simultaneously rotated in the direction of the arrow. When the electric motor 22 stops the power output, the first power output base 304 is also in a stopped state, and the lever 620 inserted on the side of the third rolling element 310 is also in a stationary state. At this time, if the first power output is outside the outer ring 400 The force is pushed backward in the opposite direction of the arrow. At this time, the third rolling element 310 is dragged by the first power output ring 400 and touches the stationary lever 620 to be displaced to a wider position of the first shaped groove 403. The first power take-off base 304 is completely disengaged from the first power output outer ring 400 as in the displacement state of FIG. At this time, the first power output outer ring 400 can be completely detached from the one-way first power output base 304 by freely rotating or moving forward in the direction of the arrow. For example, when the electric vehicle is to be retracted, the wheel housing 21 can be shifted with no step. If the transmission system is detached from the first power output outer ring 400 without resistance, it will be very labor-saving and practical.
撥杆座610的撥杆620所插設的第一單向離合結構300形態很多，例如第七圖：棘輪式單向離合器脫離結構剖面示意圖。其系包括第二動力輸出座3041、棘爪槽660、棘爪640、第三彈性元件3201、中心軸孔251。此結構為習知單向器構造，卡扣狀態如卡扣處6601。撥杆座610的撥杆620插設在棘爪640的上端，棘爪640如撥動前狀態11，具單向功能的撥杆620不動，第二動力輸出外環4001往箭頭方向8推動時，棘爪640會受撥杆620的頂壓而向異形槽孔內凹方嚮往內縮並固定如內縮狀態12，此時第二動力輸出座3041與第二動力輸出外環4001則完全脫離狀態。單向功能的離合結構形態很多，如單向軸承、單向離合器、超越離合器等。舉凡零件的等同置換，目的相同皆為本發明的範疇。The first one-way clutch structure 300 inserted into the lever 620 of the lever base 610 has many forms, for example, the seventh figure: a cross-sectional view of the ratchet type one-way clutch disengagement structure. It includes a second power output base 3041, a pawl groove 660, a pawl 640, a third elastic element 3201, and a central shaft hole 251. This structure is a conventional one-way configuration, and the buckle state is such as the buckle 6601. The lever 620 of the lever base 610 is inserted at the upper end of the pawl 640. The pawl 640 is in the state 11 before the dialing, the lever 620 having the one-way function is not moved, and the second power output outer ring 4001 is pushed in the arrow direction 8. The pawl 640 is pressed by the lever 620 to be retracted toward the concave groove in the concave direction and fixed in the retracted state 12, and the second power output base 3041 and the second power output outer ring 4001 are completely separated from each other. status. The one-way function of the clutch structure is many, such as one-way bearing, one-way clutch, overrunning clutch and so on. The equivalent of all parts is the same as the scope of the invention.
