The four-wheel aligner is used to test the wheel alignment parameters of the car, and compares with the original design parameters, and guides the user to adjust the wheel alignment parameters accordingly so that they meet the original design requirements and have achieved the ideal vehicle driving performance That is to say, the steering is light, the driving is stable and reliable, and the partial wear of the tire is reduced. It can measure and adjust the main four-wheel alignment parameters of the car, including camber, caster, caster, toe-in, and camber (SAI).
There are several types of four-wheel locator, such as front beam ruler, optical level locator, pull line locator, CCD locator, laser locator, and 3D image locator. Among them, 3D, CCD and laser products are the three mainstream products on the market. 3D products are the most advanced four-wheel positioning on the market. The advanced measurement methods and measurement time are only one-fifth of traditional positioning instruments. They have gradually entered the mature stage.
By communication method: wired communication, infrared wireless communication, RF wireless communication 433mhz, Bluetooth wireless communication, ZigBee wireless communication;
According to the measurement method: pull-wire angular displacement sensor + gravity hammer type inclinometer, pull-wire angular displacement sensor + electronic tilt sensor, laser and photoelectric receiving board + electronic tilt sensor, infrared and PSD + electronic tilt sensor, infrared and CCD + electronic Tilt sensor, infrared and CMOS image sensor, 3D technology (using area array CCD).
There are already 3D four-wheel aligners on the market, and intelligent four-wheel aligners developed by Wanlikai Technology, which are automatically selected by the environment without interference from the environment. Ordinary 3D measurement, intelligent pass-through, and non-contact measurement will be the development trend of four-wheel alignment. In the future, the measurement of four-wheel alignment will be simpler, faster and more accurate. Basic Information
l increase driving safety; l reduce tire wear; l Keep the steering wheel straight when driving straight, and keep driving straight; l The steering wheel is automatically corrected after turning; l Increase driving control; l reduce combustion consumption; l Reduce the wear of suspension parts.
