One end of the clutch is connected to the crankshaft, and the other end is connected to the main reduction gear, which is transferred to the input shaft of the transmission after the reduction. In other words, after the clutch is separated, there will be no power transferred to the transmission, so that you can easily shift and start! The motorcycle mostly USES the wet multi - disc clutch, soaked in the oil!
There are four helical springs inside the clutch to provide the pressure force, under normal circumstances do not pinch the clutch, helical spring is responsible for pressing the friction plate to transfer power, pinch clutch is to overcome the spring force so that the friction plate is no longer mutual pressure state!
Inside the clutch there are two kinds of steel plate and friction plate, an outer edge has teeth, an inner edge has teeth, the iron plate rotates with the clutch shell, the inner ring output power, when pressed into a whole, separated will have sliding not to transfer power!
When kneading and clutch, pull the wire to pull the operating lever, this will turn the tension into thrust, push the clutch housing, the spring is compressed, there is a gap between the friction plate and the iron plate can be freely rotating, do not transfer the power, release the handle, the spring presses the friction plate and the iron plate to make it a whole drive power! If the clutch cable is adjusted too tight, too little free travel will cause the clutch to slip and burn the clutch!
