how convert mechanical speedometer to gps
Find the odometer sensor plug on the clutch housing of the car. The position is different. Some are on the odometer sensor plug of the gearbox or transmission shaft, and then gently pull it out by hand. Then insert the output plug of the meter walker into the signal socket in the unplugged sensor plug. Just adjust the small adjusting button on the meter walker to adjust the car's speed to the desired speed. The speedometer indicates the speed of the car in km/h (km/h). The car odometer actually consists of two meters, one is the speedometer, the other is the odometer. The car odometer is generally in front of the driving position.
The traditional speedometer is mechanical. A typical mechanical odometer is connected to a flexible shaft. There is a steel cable inside the flexible shaft. The other end of the flexible shaft is connected to a gear of the transmission. The gear rotation drives the wire rope to rotate. The wire rope drives a magnet in the cover ring of the odometer to rotate. The cover ring is connected with the pointer and the pointer is placed at the zero position through the hairspring. The speed of the rotation of the magnet causes the change of the magnetic line of force, and the balance is broken. The pointer is driven. The speedometer is simple and practical, and is widely used in large and small cars.
Most cars use speedometers with electronic sensors without flexible shafts. One common method is to obtain signals from the speed sensor on the transmission and deflect the pointer or display the number to indicate the speed of the car through the change of pulse frequency. The car odometer also includes two LCD digital display windows connected to the same signal source to accumulate the current mileage and total mileage respectively. This mileage usually has four digits for short-term counting, which can be cleared; The total mileage has six digits and cannot be cleared. The mileage accumulated by the electronic odometer is stored in the nonvolatile memory, and the data can also be saved in the state of no power.
How to adjust the four-wheel alignment of the car
1. The so-called four-wheel positioning refers to measuring and correcting the positioning angle related to the four wheels by taking the average advancing direction of the following wheels as the positioning reference; Make the chassis parts and tires maintain proper geometric relationship when the vehicle is running, enable the driver to drive his car correctly and comfortably, and extend the service life of tires and chassis related parts.
How to slow down the speed of vehicular gps:
1. If you mean the speed of the vehicle in the GPS information, it is very difficult and the speed is very accurate. If it refers to the frequency of uploading gps information to the control platform, this can be set on the gps device.
