1 The Structure and Working Principle of Meter

[1]Speedometer

Speedometer is to indicate the running speed of motorcycle and the total mileage.It is driven by front wheel.
The rev of front wheel is sent to speedometer through gearshift system and soft axle,which makes magnetic
cylinder rotate.Coil cuts magnetic wire,which makes whirlpool and magnetic field to cooperate with the magnetic
field of magnetic cylinder,makes whirlpool disc get a torque,overcomes a resistance and drives the finger to rotate.
The higher the speed is,the stronger the magnetic field of whirlpool disc is.The torque is bigger,so the angle
of finger swing augments and it can reach the higher mark on board.Meanwhile,the rotating main axle drives
counter through whirlpool lever.Therefore,the total mileage of motorcycle is indicated by the counter.
speedometer once a year.Add luboil to where it needs.
