gps speedometer for motorcycle
The lower end of the speedometer pointer is fixed with the metal cover and connected with a hairspring, which can make the pointer swing stably and reset in time.
When the motorcycle is running, the front wheel drives the speedometer gear to rotate, which is transmitted to the magnet on the instrument drive shaft through the flexible shaft to rotate;
At this time, the magnetic line of force between the magnet and the metal cover is cut, causing the coil to generate induced current and form a magnetic field. The magnetic field interacts with the magnetic field of the magnet.
Function to turn the metal cover. The rotation of the metal cover is damped by the hairspring. When the torque of the metal cover is equal to the damping torque of the hairspring, the speedometer pointer indicates at a certain position a numerical value to indicate the driving speed.
The higher the vehicle speed, the faster the magnet rotates, the stronger the torque generated, and the greater the angle at which the metal cover drives the speedometer finger to swing.
When the vehicle speed slows down, the speed of the magnet decreases, the induced magnetic field generated in the coil weakens, and the torque decreases. Under the action of the hairspring, the speedometer pointer the swing angle also decreases.If the motorcycle stops, the magnet also stops rotating, the induced magnetic field in the coil disappears, and the speedometer pointer returns to its original position driven by the hairspring.The counter is composed of three pairs of worm gear pairs and counter drums.
Why we need to choose the speedometer with the GPS for motorcycle?
Its because in this way, the motorcycle is equipped with a GPS locator, which can be used for positioning and tracking in case of theft. It is difficult to recover after theft by simply installing an anti-theft device. After the installation of GPS locator is stolen, there is a great chance to find your car again.
