The speedometer is an important piece of equipment in every car that allows you to keep track of your speed. It is a device that informs the driver about the speed at which the vehicle is moving. The speedometer can be used in passenger cars as well as in trucks, motorcycles and other vehicles.

Types of speedometers

Speedometers can be divided into several types. One of the most commonly used are mechanical speedometers, which operate on the principle of cable gears or crank-disk gears. Cable gears are mechanical systems in which the gear transmits motion from the wheel to the gear input, which converts the speed into an indication. Crank-disc gears operate on the principle of gear transmission, in which the movement of the disc is transmitted to the wheel indicating the speed.

Another type of speedometer are electronic speedometers that use electronic pulses to measure speed. In this case, the speed signal is transmitted from the sensor located on the gearbox to the controller, which then converts the speed value into an indication.

Construction of the speedometer

The speedometer consists of several basic elements. The first of them is the gear, which is responsible for converting the speed into the indication. In the case of mechanical speedometers, this transmission consists of a crank and a gear train, while in electronic speedometers, an electronic gear is used.

Another element of the speedometer is a pointer that informs the driver about the current speed. This pointer is driven by the gear and moves along the scale of the speedometer.

The last important element of the speedometer is the dial on which the speed scale is placed. This dial can be made of different materials, such as plastic, glass or metal, depending on the model and type of speedometer.

A speedometer is an essential piece of equipment for every car that allows you to control your speed. There are several types of speedometers, including mechanical and electronic. A mechanical speedometer works on the principle of cable gears or crank disc gears, while an electronic speedometer uses electronic pulses to measure speed.
