Wheel alignment sometimes referred to as breaking, or tracking is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications. A wheel alignment is a form of car maintenance that involves adjusting the angles of a car’s wheels so that they’re at the correct angles as stated by an auto manufacturer. At the end of astandard wheel alignment, all four of a car’s wheels are guaranteed to be aligned properly.The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true. Alignment angles can also be altered beyond the maker's specifications to obtain a specific handling characteristic.
Is Wheel Alignment Necessary?
Four-wheel positioning refers to the positioning angle of the suspension system when the vehicle leaves the factory. These positioning factors are designed according to the design requirements. However, due to some reasons, some phenomena may lead to the Deterioration of vehicle performance, such as abnormal wear of the tires, accelerated wear of the parts, sinking of the steering wheel, deviation of the vehicle, and increased fuel consumption .
If the vehicle’s positioning angle is incorrect, deviations and sideslips may occur. In normal operation, the life of the tire may be shortened, and the misalignment of components will often lead to the loss of steering control. The results are unthinkable. Thus it is necessary to eliminate these situations and guarantee the stability of the vehicle. And the most effective method is do four-wheel positioning. The main purpose of a car alignment is to diagnose and treat the above-mentioned discomfort symptoms of the vehicle by the positioning angle measurement.
When Should you Align your Tires?
You’ll know that you need to have good wheel alignment done if:
* You get new tires.
* The wheels of the car wear unevenly.
* The wheels of your car wear out much faster than they should.
* Suspension parts that affect the tire angles are replaced or adjusted.
* Your steering wheel has to be crooked in order to keep your car in a straight line.
* Your car is constantly pulling to either the left or the right when you’re driving it.
* You’ve had a fender-bender or a hard impact with a curb or road debris.
* When you drive your car, it makes a lot of noise.
Regular checks are important because alignment issues aren’t always obvious. The wrong toe angle can go unnoticed, but it can lead to serious result. It’s neccessary for you to do four-wheel alignment annually or twice yearly if you often drive on rough roads.
The Basic Angles of Vehicle Wheel Alignment
The basic angles of four wheeler wheel alignment include: toe in angle, camber angle, kingpin caster angle, thrust angle, retraction angle, wheelbase, containment angle, kingpin inclination angle, steering angle, rolling radius, friction radius, body frame height, Ackerman angle, etc.
And the angles that we often need to adjust: toe in angle, camber angle, kingpin caster angle and thrust angle.
3D measurement technology of 3D wheel aligner - which based on car body, more precision and stable. Camera measurement system using two camera and work together with four target disks, which is a revolutionary measurement method. Target disk - there isn’t electronic components inner and efficiently to eliminate the equipment error which caused by circut. Calibration - only need once RCP calibration after installation, process simple and repeated calibration is unnecessary. Software system, simple operation, measurement can be finished in 2 minutes.
