   Mar 23, 2023 · How speedometers work—a closer look. When the engine turns over, the driveshaft turns to make the wheels spin round. The speedometer cable, powered by the driveshaft, turns as well. The cable spins a magnet around at the same speed inside the speed cup. The magnet rotates continually in the same direction (in this case, counter-clockwise).

   A virtual speedometer is a computer-generated tool that displays the current speed of a vehicle or object. The virtual speedometer typically calculates the object's speed based on the distance it travels over time. Such speedometers are programmed using programming languages such as HTML, CSS, and Javascript.

   The mechanical speedometer features a pointer that shows the vehicle's speed. As the car wheels rotate, the pointer moves across the range of speeds. How does a mechanical speedometer work? The pointer moves because of the electromagnetism produced by the shaft and cable that are connected to the spinning wheels.

   speedometer, instrument that indicates the speed of a vehicle, usually combined with a device known as an odometer that records the distance traveled. British inventor Charles Babbage invented an early type of speedometer made for locomotives, though Croation inventor Josip Belušić is credited with inventing the electric speedometer in 1888.

   Jerky operation of the speedometer pointer is a fairly certain indication that the cable needs lubricating, although a damaged cable may produce the same symptom. To lubricate, it is necessary to remove the cable complete with tube, which is usually secured by .1 knurled screw cap, bolt or circlip at both the gearbox and the back of the speedometer.

   How does a speedometer pointer work?

   • At a given speed, the pointer will remain motionless and point to the appropriate number on the speedometer's dial. The return spring is calibrated such that a given revolution speed of the cable corresponds to a specific speed indication on the speedometer.

   How do mechanical speedometers measure the speed of a car?

   • Mechanical speedometers measure the speed of a car by being linked mechanically with the gearbox output shaft . Since this shaft lies 'downstream' of the gear box, the speed with which it rotates is independent of gear changes and so gives a true measure of the road speed. Gearbox output shaft.

   How does a speedometer cable work?

   • While this happens, the speedometer cable is also turning because it is powered by the driveshaft. The cable forces the magnet to also spin around the speed cup at the same speed. It rotates in the same direction continually. This magnet produces eddy currents, which forces the cup to rotate while attempting to catch up.

   Can a speedometer tell you your actual speed?

   • Only a speedometer can tell you your actual speed at any given moment. What we're talking about here is average speed; what you need to know as a motorist is your instantaneous speed: the speed you're going at any given moment. Figuring that out is a lot harder than you think.
