上方兩個圓盤靠摩擦的方式輸入後，傳到一個差速器，再傳到傘齒輪最後是蝸桿組，由右上方的切換桿可以改變輸出軸的轉向。 Input from the top by two plate via then the input is transferred, where it is next transferred into a differential, to a bevel gear, and final into a set of worm gear. The direction of the output axis can be altered by the lever on the top right.
