One end of the clutch is connected to the crankshaft and the other end to the main reduction gear, which is then transferred to the input shaft of the transmission. This means that after the clutch disengages, no power will be transferred to the transmission, so that the gear can be shifted and started easily! Most of the motorcycle is a wet multi - plate clutch, soaking in the oil!
There are four helical springs in the clutch to provide the compression force. Under normal circumstances, the helical spring is responsible for the compression of the friction disc to transfer power. The clutch clutch is to overcome the spring's elasticity so that the friction discs are no longer in a state of mutual compression!
Inside the clutch there are two kinds of steel plate and friction plate, one of the outer edge has teeth, one of the inner edge has teeth, the iron plate follows the clutch shell to rotate together, the inner ring output power, when the pressure becomes a whole, after the separation there will be sliding not transfer power!
When pinch clutch, the pull line pulls the operating lever, which will turn the tension into thrust and push the clutch shell. The spring is compressed. The gap between the friction plate and the iron plate can rotate freely without transferring power. If the clutch cable is adjusted too tight, the free stroke is too small and will cause the clutch to slip and burn the clutch!
