How to Read the Odometer?
1 Answers
Cars have the following two types of odometer readings: 1. Pointer: This shows the actual mileage at the time of driving, indicating the speed per hundred kilometers. 2. Digital rolling: This displays the actual kilometers traveled. Rolling numbers can be further divided into changeable and unchangeable types. Changeable ones are typically four-digit, while unchangeable ones are six-digit or more. Below is relevant information: 1. The speedometer indicates the car's speed in km/h (kilometers per hour). The odometer actually consists of two meters: a speedometer and an odometer. The odometer is usually located directly in front of the driver's position. 2. Traditional speedometers are mechanical. A typical mechanical odometer is connected via a flexible shaft containing a steel cable. The other end of the flexible shaft connects to a gear in the transmission. The rotation of the gear drives the steel cable, which in turn rotates a magnet inside the odometer's housing. The housing is linked to the pointer, and a hairspring keeps the pointer at zero. The speed of the magnet's rotation affects the magnetic field strength, disrupting the balance and causing the pointer to move. This type of speedometer is simple and practical, widely used in both small and large vehicles. 3. Most modern cars use electronic sensor-based speedometers without flexible shafts. A common type obtains signals from a speed sensor on the transmission, using changes in pulse frequency to deflect the pointer or display digital numbers indicating the car's speed.
