On the front panel of every vehicle is an instrumentation combination that includes a tachometer, fuel gauge, temperature gauge, clock, etc. But one of the biggest and most important Dick’s Speed-O-Tach is the speedometer. This is what the driver pays the most attention to during the trip. The speedometer indicates the speed of the car (kilometers per hour, miles per hour).
There are two types of speedometers: digital and mechanical. The digital speedometer is not a relatively new invention. The first such speedometer was released back in 1993. Otto Schulze, the inventor of Strasbourg, had the idea to create a speed meter in 1902. With the increasing popularity of large vehicles, the average speed also increased.
The maximum speed in the early twentieth century was 30 miles per hour. Although by today’s standards this number is small, back then it was much faster than horse-drawn carts, making it more popular by the day. As a result, it also dramatically increased the number of accidents. Schulz’ new invention allowed the driver to control the speed of their movement, giving them the control for a more precise ride. In many countries, with the advent of speedometers, traffic police were formed.
In determining the speed of the car, the first thing that a speedometer must conclude is the speed of the wheels. This information is transmitted by the measuring instruments. The speed assembly consists of a permanent magnet mounted on the compass card and the drive roller which is mounted on the axis. At the upper end of the shaft is an arrow in the middle part, pressed onto the coil spring. The inner end of the spring is fixed to the hub and outside – on the plate, serving to adjust the tension of the spring assembly for adjusting the velocity. The screen is disposed around the compass card, which is intended to increase magnetic flux.
The magnetic fields and compass card creates torque. The rotation axis of the compass card prevents the return spring, screwed with increasing momentum with counteracting momentum. Odometers record the traversed path of the vehicle. Mileage works similar to the work of the speedometer. 1000 crankshaft speed is fixed at 1 miles traversed. Tachometer displays the speed of the crankshaft, thus letting you know how fast you are going. For more information on gauges in Arizona, contact your local dealer today.
