The four-wheel aligner plays a very important role in the normal driving of a car. Car owners must not ignore it. After the car has been driven for a period of time, due to various reasons, phenomena such as abnormal tire wear, accelerated wear of parts, heavy steering wheel, vehicle deviation, and increased fuel consumption will occur. These phenomena are all reasons for the decline in vehicle performance. To eliminate these phenomena and ensure the stability of the vehicle, an effective method is to do four-wheel alignment. It can not only ensure the normal driving of the car, but also prolong the service life of the tires and save fuel consumption at the same time.
Four-wheel alignment refers to the positioning angles of the suspension system of a vehicle when it leaves the factory. These positioning angles are preset according to design requirements to ensure the safety of vehicle driving. The above angles refer to the angles between the suspension system and various moving parts. Maintaining correct four-wheel alignment angles can ensure the straight-line driving performance, handling and steering system responsiveness of the vehicle, avoid improper stress on bearings and damage and loss of precision, and can also ensure that the tires are in close contact with the ground and reduce improper tire wear and ensure the stability of the car when turning.
The purpose of four-wheel alignment is to diagnose and treat the above-mentioned uncomfortable symptoms of the vehicle through positioning angle measurement. It is divided into front wheel alignment and rear wheel alignment. Front wheel alignment includes four contents: caster angle, kingpin inclination angle, front wheel camber angle and front wheel toe. Rear wheel alignment includes wheel camber angle and individual rear wheel toe. Under normal circumstances, after driving a new car for 3 months, four-wheel alignment should be done. After that, every 10,000 kilometers of driving, the tires should be rotated. If there is a collision, four-wheel alignment should be done in time.
The above has talked about the importance of four-wheel alignment of a car. Now let's talk about the issues that should be paid attention to when doing four-wheel alignment. When choosing a car maintenance shop, you must choose a professional car maintenance shop. Because technicians with both experience and technology combined with advanced four-wheel aligners can provide services for your beloved car. With the evolution of the suspension system from simple to complex, its structure is becoming more and more complex, and the corresponding requirements for four-wheel alignment angles are getting higher and higher. Therefore, there is a four-wheel aligner designated for a certain model. However, the four-wheel aligner is not an instrument used to adjust and change the positioning angle. It is only used to measure the positioning angle. Then, technicians use this as a reference and compare it with the angle set by the original factory to adjust and change the positioning angle to restore the original design angle.
In addition, the main factors affecting four-wheel alignment are: (1) Driving at high speed on an uneven road; (2) The front wheel is impacted by external forces, such as going up a sidewalk curb; (3) Often turning the steering wheel to the end in place; (4) Tire pressure exceeds the standard range. Therefore, when car owners maintain your beloved car, you should pay attention to the following points: (1) When passing through obstacles, try to drive slowly and detour; (2) The tire treads of the front wheels must be consistent to ensure driving performance and prevent phenomena such as insufficient adhesion, noise, sideslip, and uneven wear; (3) After renewing or repairing tires, tire dynamic balance test must be carried out.
