The speedometer is one of the most important pieces of equipment in any car. Its primary task is to measure the speed of the vehicle. The speedometer is an extremely important element that allows you to control your speed and ensures safety on the road.
Types of speedometers in cars
A speedometer is a mechanical, electronic or hybrid device. Depending on the type, several types of speedometers can be distinguished. The most popular are mechanical, electromechanical and electronic speedometers.
A mechanical speedometer consists of two main parts: a gear train and a speed indicator. The gear train is connected to the gearbox shaft and rotates with it. The speed indicator, in turn, is connected to the transmission and moves along the scale located on the dial of the speedometer. An electromechanical speedometer works in a similar way, except that the gear train is replaced with a sensor that sends a signal to the speed indicator.
The electronic speedometer is more complicated, but also more precise. In this case, the speed signal is generated by a sensor located on the drive shaft. This signal is then sent to the controller, which calculates the speed and displays it on the LCD screen.
It is worth noting that the speedometer is not the only tool for measuring speed. Some cars also use GPS navigation systems that offer precise speed measurement.
To sum up, the speedometer is an extremely important element of every car’s equipment, which ensures safety on the road. Depending on the type, speedometers may have a different structure and principle of operation, but their basic task remains the same – measuring the speed of the vehicle.
