Description

無段變速環座驅動機構
本發明係提供一種無段變速環座驅動機構，尤指一種摩擦損耗低且變速效率高的無段變速環座驅動機構。
為使交通工具可調整速度或降低油耗，因此目前的交通工具皆設置有排檔機構。一般的排檔機構主要係藉由齒輪組，或藉由齒輪組與油道，或藉由滑輪組與皮帶，或藉由變速桿偏轉變速球體。其中，在藉由變速桿偏轉變速球體的排檔機構中，由於其驅動變速的機構的摩擦損耗多，因此，如何發明出一種無段變速環座驅動機構，以使其可降低摩擦損耗移以提高變速效率，將是本發明所欲積極揭露之處。
有鑑於上述習知技術之缺憾，發明人有感其未臻於完善，遂竭其心智悉心研究克服，進而研發出一種無段變速環座驅動機構，以期達到摩擦損耗低且變速效率高的目的。
本發明係提供一種無段變速環座驅動機構，其包含：一圓柱座體，其具有一圓環形槽，該圓環形槽具有一圓環形底壁及二圓環形側壁，該圓環形底壁具有複數軸向導引孔，該等軸向導引孔分別用以容置一無段變速桿；複數滾輪，其樞設於該圓環形底壁及該等圓環形側壁以部分露出於該圓環形槽內；以及一無段變速圓環體，其活動容置於該圓環形槽，該無段變速圓環體的內圓環形面接觸該圓環形底壁的該等滾輪，該無段變速圓環體的二側圓環形面分別接觸該等圓環形側壁的該等滾輪，該無段變速圓環體具有複數斜向導引孔，該無段變速圓環體繞該圓柱座體轉動時，該等斜向導引孔分別用以導引該無段變速桿沿該圓柱座體的軸向移動。
上述的無段變速環座驅動機構中，該圓柱座體具有相互連接的二半圓柱座體，該等半圓柱座體分別具有一半圓環形底壁、複數半軸向導引孔及該圓環形側壁。
上述的無段變速環座驅動機構中，更包含一驅動源以驅動該無段變速圓環體繞該圓柱座體轉動。
上述的無段變速環座驅動機構中，該無段變速圓環體的外圓環形面上設置有至少一圓弧形驅動齒條，該圓弧形驅動齒條沿該無段變速圓環體的轉動方向設置，該驅動源具有至少一驅動齒輪以嚙合於該圓弧形驅動齒條。
藉此，本發明的無段變速環座驅動機構的摩擦損耗低且變速效率高。
為充分瞭解本發明之目的、特徵及功效，茲藉由下述具體之實施例，並配合所附之圖式，對本發明做一詳細說明，說明如後：
請參考圖1至圖6，如圖所示，本發明係提供一種無段變速環座驅動機構，其包含一圓柱座體1、複數滾輪2及一無段變速圓環體3。其中，該圓柱座體1的圓形周界處具有一圓環形槽12，該圓環形槽12具有一圓環形底壁13及二圓環形側壁14，該等圓環形側壁14位於該圓環形底壁13的二側且由該圓環形底壁13沿該圓柱座體1的徑向向外延伸，該圓環形底壁13具有複數軸向導引孔15，該等軸向導引孔15以相同間隔平行排列於該圓環形底壁13，各該軸向導引孔15沿該圓柱座體1的軸向呈狹長形且其徑向截面呈十字形，該等軸向導引孔15分別用以容置十字形的一無段變速桿4，各該無段變速桿4樞接一無段變速球體5；該等滾輪2樞設於該圓環形底壁13及該等圓環形側壁14，且各該滾輪2的一部分露出於該圓環形槽12內，該等滾輪2以相同間隔排列於該圓環形底壁13，該等滾輪2以相同間隔排列於各該圓環形側壁14；該無段變速圓環體3活動容置於該圓環形槽12，該無段變速圓環體3的內圓環形面31接觸該圓環形底壁13的該等滾輪2，該無段變速圓環體3的二側圓環形面32分別接觸該等圓環形側壁14的該等滾輪2，該無段變速圓環體3具有複數斜向導引孔33，該等斜向導引孔33以相同間隔平行排列於該無段變速圓環體3，各該斜向導引孔33傾斜於該無段變速圓環體3的轉動軸心且呈狹長形，該無段變速圓環體3繞該圓柱座體1轉動時，該等斜向導引孔33分別用以導引該無段變速桿4沿該圓柱座體1的軸向移動，並偏轉該無段變速球體5以進行無段變速。
如上所述，請參考圖1、圖3及圖6，如圖所示，當該無段變速圓環體3逆時針轉動時，各該無段變速桿4由於各該軸向導引孔15及各該斜向導引孔33的導引而會向右移動並向右偏轉各該無段變速球體5；當該無段變速圓環體3順時針轉動時，各該無段變速桿4由於各該軸向導引孔15及各該斜向導引孔33的導引而會向左移動並向左偏轉各該無段變速球體5。另外，由於該無段變速圓環體3是藉由該等滾輪2繞該圓柱座體1轉動，因此該無段變速圓環體3與該圓柱座體1之間僅具有滾動摩擦，摩擦損耗小，變速效率高。
請參考圖1及圖2，如圖所示，上述的無段變速環座驅動機構中，該圓柱座體1可具有相互連接的二半圓柱座體11，該等半圓柱座體11分別具有一半圓環形底壁131、複數半軸向導引孔151、複數半容置孔161及該圓環形側壁14，二半圓環形底壁131可相互連接形成該圓環形底壁13，二半軸向導引孔151可相互連接形成該軸向導引孔15以容置該無段變速桿4，二半容置孔161可相互連接形成一容置孔16以容置該無段變速球體5。藉此，當該無段變速圓環體3與該圓柱座體1組接時，該等半圓柱座體11可先套入該無段變速圓環體3內再相互連接形成該圓柱座體1，以使該無段變速圓環體3便於與該圓柱座體1組接。
請參考圖1至圖6，如圖所示，上述的無段變速環座驅動機構中，更可包含一驅動源6以驅動該無段變速圓環體3繞該圓柱座體1轉動。另外，該無段變速圓環體3的外圓環形面35上可設置有至少一圓弧形驅動齒條34，該圓弧形驅動齒條34沿該無段變速圓環體3的轉動方向設置，該驅動源6可具有一伺服馬達(圖未示)及至少一驅動齒輪61以嚙合於該圓弧形驅動齒條34。藉此，本發明的無段變速環座驅動機構可藉由該伺服馬達帶動該驅動齒輪61及該圓弧形驅動齒條34以驅動該無段變速圓環體3繞該圓柱座體1轉動。
本發明在上文中已以較佳實施例揭露，然熟習本項技術者應理解的是，該實施例僅用於描繪本發明，而不應解讀為限制本發明之範圍。應注意的是，舉凡與該實施例等效之變化與置換，均應設為涵蓋於本發明之範疇內。因此，本發明之保護範圍當以申請專利範圍所界定者為準。
