請參閱圖1、圖2及圖3，其分別為三陽工業股份有限公司所申請之台灣第103142830號「多模式無段變速機構」專利申請案之習知多模式無段變速機構之剖視圖、局部放大圖及四連桿機構之分解圖。該多模式無段變速機構係組裝於一機車上，包括有：一入力軸1、一驅動盤組2、一切換模組5以及二滾珠軸承58,59。驅動盤組2包括有：一驅動盤21、一滑動驅動盤22、一不動壓板23、一可動壓板25、複數擋止塊26、複數連桿27及複數驅動元件24。 Please refer to FIG. 1, FIG. 2 and FIG. 3, which are respectively a cross-sectional view and a partial view of a conventional multi-mode stepless shifting mechanism of the patent application No. 103142830 of the Taiwanese application filed by Sanyang Industrial Co., Ltd. Enlarged view and exploded view of the four-bar linkage mechanism. The multi-mode stepless shifting mechanism is assembled on a locomotive, and includes: an input shaft 1, a driving disc group 2, a switching module 5, and two ball bearings 58, 59. The drive plate set 2 includes a drive plate 21, a slide drive plate 22, a stationary platen 23, a movable platen 25, a plurality of stop blocks 26, a plurality of links 27, and a plurality of drive elements 24.
其驅動盤21以及不動壓板23係同軸固設於入力軸1上，滑動驅動盤22係位於驅動盤21與不動壓板23之間，並同軸滑設於入力軸1上，複數驅動元件24係設置於滑動驅動盤22與不動壓板23之間。其中，驅動元件24係為滾珠。當入力軸1旋轉時，可促使複數驅動元件24以其離心力而頂推滑動驅動盤22沿入力軸1作軸向滑動。 The driving plate 21 and the stationary pressing plate 23 are coaxially fixed on the input shaft 1 , and the sliding driving plate 22 is located between the driving plate 21 and the fixed pressing plate 23 , and is coaxially slidably disposed on the input shaft 1 , and the plurality of driving elements 24 are disposed. Between the sliding drive plate 22 and the stationary platen 23. Among them, the driving element 24 is a ball. When the input shaft 1 rotates, the plurality of driving elements 24 can be caused to push the sliding drive disk 22 to axially slide along the input shaft 1 by its centrifugal force.
此外，如圖1與圖3所式，不動壓板23設有六開孔231，可動壓板25具有六凸出銷251，可動壓板25設置於不動壓板23之外側，並同軸滑設於入力軸1上，可動壓板25之每一凸出銷251分別對應伸入不動壓板23之每一開孔231，且每一凸出銷251之前端連接一擋止塊26，複數驅動元件24係設置於滑動驅動盤22與複數擋止塊26之間，每一擋止塊26再藉由一連桿27與不動壓板23相連，且可動壓板25與切換模組5相連接，故切換模組5可控制可動壓板25之軸向移動，進而改變可動壓板25之軸向位置。 In addition, as shown in FIG. 1 and FIG. 3, the stationary platen 23 is provided with six openings 231, and the movable platen 25 has six protruding pins 251. The movable pressing plate 25 is disposed on the outer side of the stationary pressing plate 23, and is coaxially slidably disposed on the input shaft 1 Each of the protruding pins 251 of the movable platen 25 respectively extends into each of the openings 231 of the stationary platen 23, and a front end of each of the protruding pins 251 is connected to a blocking block 26, and the plurality of driving elements 24 are disposed on the sliding plate. Between the driving plate 22 and the plurality of blocking blocks 26, each blocking block 26 is connected to the fixed pressing plate 23 by a connecting rod 27, and the movable pressing plate 25 is connected with the switching module 5, so the switching module 5 can be controlled. The axial movement of the movable platen 25 changes the axial position of the movable platen 25.
其中，不動壓板23是由一不動壓板本體232及三個不動壓板肋塊233所構成。另，不動壓板23係具有六個開孔231，相對應地，可動壓板25具有六個凸出銷251，且連桿27、擋止塊26及驅動元件24之數量皆為六個。此外，其四連桿機構之動作原理為：擋止塊26之二端分別與可動壓板25之凸出銷251及連桿27樞設連接。另，連桿27之二端則分別與擋止塊26及不動壓板23樞設連接。因此，擋止塊26、連桿27、不動壓板23與可動壓板25相互樞設連接形成一四連桿機構，僅有可動壓板25可藉由切換模組5之控制而軸向滑動，進而可使擋止塊26與驅動元件24之接觸位置及角度可變的。 The stationary platen 23 is composed of a stationary platen body 232 and three fixed platen ribs 233. In addition, the stationary platen 23 has six openings 231. Correspondingly, the movable platen 25 has six protruding pins 251, and the number of the connecting rod 27, the stopping block 26 and the driving element 24 are six. In addition, the four-link mechanism operates on the principle that the two ends of the blocking block 26 are respectively pivotally connected to the protruding pin 251 and the connecting rod 27 of the movable platen 25. In addition, the two ends of the connecting rod 27 are respectively pivotally connected to the stopping block 26 and the stationary pressing plate 23. Therefore, the blocking block 26, the connecting rod 27, the stationary pressing plate 23 and the movable pressing plate 25 are pivotally connected to each other to form a four-bar linkage mechanism, and only the movable pressing plate 25 can be axially slid by the control of the switching module 5, thereby The position and angle of contact between the stop block 26 and the drive element 24 are variable.
如圖1所式，切換模組5包括有：一具有內螺牙511之被驅動齒輪51、一與被驅動齒輪51相嚙合之驅動齒輪52、一與驅動齒輪52相連接之馬達53，以及一具有一外螺牙541之套筒54，套筒54係與可動壓板25連結，二者可一起軸向滑動，且藉由外螺牙541使套筒54螺合於被驅動齒輪51之內螺牙511。 As shown in FIG. 1 , the switching module 5 includes: a driven gear 51 having an internal thread 511 , a driving gear 52 meshing with the driven gear 51 , and a motor 53 connected to the driving gear 52 , and A sleeve 54 having an outer thread 541, the sleeve 54 is coupled to the movable platen 25, the two of which are axially slidable together, and the sleeve 54 is screwed into the driven gear 51 by the external thread 541 Screw 511.
切換模組5之作動原理為：藉由馬達53帶動驅動齒輪52旋轉進而帶動被驅動齒輪51旋轉，被驅動齒輪51藉由內螺牙511螺合於套 筒54之外螺牙541，且被驅動齒輪51於軸向上為固定不動，當被驅動齒輪51旋轉時可藉由內螺牙511、外螺牙541之作用以驅動套筒54做軸向位移，故藉由套筒54之移動即可帶動可動壓板25於軸向上產生位移。 The operation principle of the switching module 5 is that the driving gear 52 is rotated by the motor 53 to drive the driven gear 51 to rotate, and the driven gear 51 is screwed to the sleeve by the internal thread 511. The outer portion of the cylinder 54 is screwed 541, and the driven gear 51 is fixed in the axial direction. When the driven gear 51 rotates, the inner thread 511 and the outer thread 541 act to drive the sleeve 54 to be axially displaced. Therefore, the movable platen 25 can be displaced in the axial direction by the movement of the sleeve 54.
此外，有一滾珠軸承58套設於可動壓板25之套設部252，並鄰接於套筒54之內環面，以使套筒54不與可動壓板25一起旋轉。另外，其入力軸1上套設一滾珠軸承59鄰接於被驅動齒輪51之內環面，可使被驅動齒輪51不與入力軸1一起旋轉。 Further, a ball bearing 58 is sleeved on the sleeve portion 252 of the movable platen 25 and abuts against the inner annular surface of the sleeve 54 so that the sleeve 54 does not rotate together with the movable platen 25. Further, a ball bearing 59 is fitted over the input shaft 1 to abut against the inner ring surface of the driven gear 51, so that the driven gear 51 does not rotate together with the input shaft 1.
由上說明，上述習知四連桿機構之可動壓板25上之複數凸出銷251需穿過不動壓板23上之複數開孔231，每一擋止塊26再藉由一連桿27與不動壓板23相連，整體四連桿機構形成多個滑動及轉動關節，如此將多個軸孔的互相滑動配合，需要求軸孔間的配合間隙、位置度、平行度，該等滑動及轉動關節之製造精度要求甚高。此外，若滑動及轉動關節配合間隙大，則將造成關節的磨損。另外，上述習知四連桿機構零件數目多，不僅增加成本，且造成組裝之不便，並非十分理想，尚有改善之空間。 As described above, the plurality of protruding pins 251 on the movable platen 25 of the conventional four-bar linkage mechanism are required to pass through the plurality of openings 231 on the movable platen 23, and each of the blocking blocks 26 is further moved by a connecting rod 27 The pressure plate 23 is connected, and the whole four-bar linkage mechanism forms a plurality of sliding and rotating joints. Therefore, the sliding fit of the plurality of shaft holes is required, and the matching clearance, the positional degree and the parallelism between the shaft holes are required, and the sliding and rotating joints are required. Manufacturing accuracy is very high. In addition, if the sliding and rotating joints have a large clearance, the joint will be worn. In addition, the above-mentioned conventional four-bar linkage mechanism has a large number of parts, which not only increases the cost, but also causes inconvenience in assembly, and is not ideal, and there is still room for improvement.
發明人緣因於此，本於積極發明創作之精神，亟思一種可以解決上述問題之「多模式無段變速機構」，幾經研究實驗終至完成本發明。 Because of this, the inventor of this invention, in the spirit of active invention and creation, considers a "multi-mode stepless shifting mechanism" that can solve the above problems, and has completed research and experiments to complete the present invention.

The present invention uses a rocker arm and a pushing mechanism to replace the above-mentioned conventional four-bar linkage mechanism, and the rocker arm and the non-moving pressure plate are pivotally coupled to form a rotating joint, and the pushing mechanism is topped. Pushing the rocker arm so that the rocker arm rotates around the rotating joint, and the pushing mechanism is further connected with the switching module to control the pushing mechanism The axial movement, which in turn changes the angle of the sliding surface of the drive element and the rocker arm, produces a plurality of shift modes.
為達成上述目的，本發明之多模式無段變速機構包括有：一入力軸、一推動機構、及一驅動盤組，驅動盤組包括有一驅動盤、一滑動驅動盤、一不動壓板以及複數驅動元件。其中，不動壓板設有複數開孔及複數搖臂，複數驅動元件位於複數搖臂與滑動驅動盤之間，推動機構設置於不動壓板之外側，並同軸滑設於該入力軸上，每一搖臂之一端與不動壓板樞接結合形成一旋轉關節，推動機構之一頂推部頂抵該搖臂，使該搖臂以該旋轉關節為中心旋轉，推動機構並與一切換模組相連接，以控制推動機構之軸向移動，進而改變該驅動元件與該搖臂之滑動面角度而可產生多種變速模式。藉此，本發明較習知之四連桿機構具有零件數目較少、可降低成本且利於組裝、結構緊湊可縮短入力軸長度與引擎寬度等優點。 To achieve the above object, the multi-mode stepless shifting mechanism of the present invention comprises: an input shaft, a pushing mechanism, and a driving disc set, the driving disc set including a driving disc, a sliding driving disc, a stationary pressing plate and a plurality of driving element. The movable platen is provided with a plurality of openings and a plurality of rocker arms, and the plurality of driving elements are located between the plurality of rocker arms and the sliding drive plate, and the pushing mechanism is disposed on the outer side of the movable platen, and is coaxially slidably disposed on the input shaft, each rocking One end of the arm is pivotally coupled with the non-moving pressure plate to form a rotating joint, and one of the pushing portions of the pushing mechanism abuts against the rocking arm, so that the rocking arm rotates around the rotating joint, and the pushing mechanism is connected with a switching module. A plurality of shift modes can be generated by controlling the axial movement of the push mechanism, thereby changing the angle of the sliding surface of the drive member and the rocker arm. Therefore, the conventional four-bar linkage mechanism of the present invention has the advantages of fewer parts, lowering cost, facilitating assembly, compact structure, and shortening the length of the input shaft and the width of the engine.
上述推動機構之頂推部可為一軸承之內環或外環，亦即可利用推動機構之軸承之內環直接頂推搖臂；或者，也可利用推動機構之軸承之外環直接頂推搖臂，使搖臂以其旋轉關節為中心旋轉，進而改變驅動元件與搖臂之滑動面角度，而產生多種變速模式。 The pushing portion of the pushing mechanism may be an inner ring or an outer ring of a bearing, or the inner ring of the bearing of the pushing mechanism may directly push the rocker arm; or, the outer ring of the bearing of the pushing mechanism may be directly pushed The rocker arm rotates the rocker arm around its rotating joint, thereby changing the angle of the sliding surface of the driving element and the rocker arm, and generating a plurality of shifting modes.

上述推動件與搖臂之接觸面可固設有一接觸件，用以避免變速機構作動時推動件之磨損。此外，推動件與接觸件之材質可不同，推動件可為金屬材質，而接觸件可為橡膠材質，因變速機構於作動時， 搖臂與接觸件會相對滑動而恐有磨耗，故以接觸件作為耗材，可方便更換並節省成本。 The contact surface of the pushing member and the rocker arm can be fixed with a contact member to avoid the wear of the pushing member when the shifting mechanism is actuated. In addition, the material of the pushing member and the contact member may be different, the pushing member may be made of metal, and the contact member may be made of rubber, because the shifting mechanism is actuated. The rocker arm and the contact member will slide relative to each other and may be worn. Therefore, the contact member is used as a consumable material, which can be easily replaced and cost-saving.
