Description
本發明涉及一種自行車變速裝置，尤指一種自行車八速內變速器。 The invention relates to a bicycle shifting device, in particular to a bicycle eight-speed internal transmission.
自行車的變速器依組成機構與裝設方式的差異，主要可區分為外變速器與內變速器，兩者皆是設置於自行車後輪輪轂處，外變速器係設置於輪轂外，而內變速器則是設置於輪轂內，一般的內變速器通常係以行星齒輪系做為變速機構主體，動力的部份由鏈輪輸入，並藉由切換不同的構件、改變轉速與扭矩後，將動力由輪轂輸出至後輪，以達到多段變速的目的。 The bicycle transmission can be mainly divided into an external transmission and an internal transmission according to the difference between the constituent mechanism and the installation mode, both of which are disposed at the rear wheel hub of the bicycle, the outer transmission is disposed outside the hub, and the internal transmission is disposed at In the hub, the general internal transmission usually uses the planetary gear train as the main body of the shifting mechanism. The power part is input by the sprocket. After switching the different components and changing the speed and torque, the power is output from the hub to the rear wheel. In order to achieve the purpose of multi-speed shifting.
現有的內變速器多利用平移式的控制件進行調速，利用軸向位置的變化驅動不同位置的行星齒輪，以完成多段檔位的調整、達到切換不同變速檔位的目的。 The existing internal transmission uses the translating control unit to adjust the speed, and uses the change of the axial position to drive the planetary gears at different positions to complete the adjustment of the multi-stage gear position and achieve the purpose of switching different shift gear positions.
然而，現有的自行車內變速器也因此需要較大的軸向空間以便行程進行，故輪轂需較大體積才可提供較大的內部空間予內變速器裝設，與目前自行車產業所要求的輕量化要求不符，所述缺失實有改善之必要。 However, the existing bicycle internal transmission also requires a large axial space for the stroke to be carried out, so that the hub needs a large volume to provide a large internal space for the internal transmission installation, and the lightweight requirements required by the current bicycle industry. Inconsistent, the lack of improvement is necessary.
