| Motorcycle Meter works: Motorcycle instrumentation including odometer and speedometer . Odometer by a drive shaft under the flexible shaft of the front wheel is connected to a set of drive gears , a round permanent magnet fixed to the driving shaft and the drive shaft rotate together as a group of one of the metal coil cap on the outer periphery of the magnet between them is not in contact with each other , there is a certain gap . The lower end of the speedometer pointer fixed together with metal cover and is connected with a gossamer , gossamer makes pointer swing smooth and timely reset. When the motorcycle driving , the front wheel speedometer drive gear, shaft passing through the magnet to the drive shaft rotation of the instrument , this time, the magnet and the magnetic field lines between the metal cover is cut , the coil generates a magnetic field induced current . The magnetic interaction between the magnetic field of the permanent magnet , the metal cover rotating . By rotation of the metal cover of the damping spring , when the metal cover and the spring torque is equal to the damping torque , speedometer pointer indicating a certain value , and to indicate that the traveling speed . The higher the speed , the faster the rotation of the permanent magnet , the stronger the torque generated by the metal cover to drive the speedometer needle swing angle greater . When the vehicle slows down , the permanent magnet speed decreases , the induced magnetic field generated in the coil weakening , the torque becomes small, the action of springs , the speedometer needle swing angle becomes small . If the motorcycle is stopped , it stopped rotating permanent magnet , coil induced magnetic field disappears , the speedometer pointer gossamer driven back into place . Counter consists of three pairs Worm and counter drum composition . The end of the worm gear driven rotary shaft rotation , when the rotating shaft 1000 rpm, the revolution of the end of the worm gear , worm gear at the end face at the end of the dial with convex jaw , the end of each revolution of the worm wheel , the toggle engraved 0-9 of counter rotating drum 1/ 10 weeks . Register drum and motorcycle gear ratio between : wheel travel one kilometer , the right of the counter drum turning 10 last cell scale grid . At this point, the second from right to left turning a lattice grid scale . Means that the vehicle 1 km . When traveling 10 kilometers , the counter on the second drum drum drum through the embossed toggle third scale from 0 to 1 , which means that the vehicle traveled 10 km , the first drum per revolution , dial moving the second drum rotation a grid ; second drum rotation one week , toggle third drum rotation of a cell, until traveling 99,999 km . When this number is exceeded , the drum and all go to 0, reading again from scratch , so recycling. Source: Motorcycle Meter Network News Source: Motorcycle Meter |
