Description

雙軸離合變速裝置
一種雙軸離合變速裝置，尤指一種利用雙軸結構，而達到體積縮減之變速系統。
變速機構係為電動車輛/傳統車輛(以下以車輛通稱)之不可缺少的構件，變速機構係為車輛行進時，提供不同的轉速或扭矩的要求。
上述之轉速、扭矩的轉換係透過多個齒輪所達到。故現有的變速機構內部具有多個齒輪組合。然而該齒輪組合使得現有的齒輪箱的體積過大，由於體積較大的變速機構係使得車輛於設計時，往往需要考量需有較大空間以容置現有的變速機構，因此造成車輛於設計上的難度。
另外，現有的傳動系統，其驅動與傳動係各自獨立，所以具有總體積大、功率密度低的缺點。
雖有部分廠商欲利用離合器，以縮減變速機構的體積，但其縮減量有限，故如何縮減現有的變速機構之體積就有可改善的空間。
本發明係一種雙軸離合變速裝置，其包含有：一驅動單元；一輸入軸，其係耦接該驅動單元，該輸入軸具有一輸入齒輪；一輸出軸，其一端係穿過該輸入軸與該驅動單元，該輸出軸的另一端具有至少一奇數輸出齒輪與至少一偶數輸出齒輪；一殼體，其具有一殼體齒輪； 至少一奇數離合單元，其係設於該殼體的內部，該奇數離合單元具有一奇數離合軸與一奇數離合齒輪；以及至少一偶數離合單元，其係設於該殼體的內部，該偶數合單元具有一偶數離合軸與一偶數離合齒輪；其中，該偶數離合軸的一端係穿過於該殼體，並且突出於該殼體的外部，該偶數離合齒輪係設於該偶數離合軸突出於殼體的一端，該偶數離合齒輪係嚙合該偶數輸出齒輪；該奇數離合軸的一端係穿過該偶數離合軸，且突出於該偶數離合軸的外部，該奇數離合齒輪係設於該奇數離合軸突出於該偶數離合軸的一端，該奇數離合齒輪係嚙合該奇數輸出齒輪。
