The through-type 4-wheel alignment plays a very important role in the normal driving of the vehicle. Many car owners should not underestimate it. After the vehicle has been running for a certain period of time, due to various reasons, abnormal wear of tires, accelerated wear of parts, heavy steering wheels, vehicle deviation, increased fuel consumption, etc. will occur. These conditions are the reasons for the reduction of vehicle performance. To solve these conditions and ensure the stability of the vehicle, the more reasonable way is to do 4-wheel alignment, which can not only ensure the normal driving of the vehicle, but also increase the service life of the tires and reduce fuel consumption.
4-wheel alignment refers to the positioning angle of the suspension system of the vehicle when it leaves the factory. These positioning angles are set in advance according to the design standards to ensure the safety factor of the vehicle. The above angles refer to the angles between the suspension system and various active parts. Maintaining the correct 4-wheel alignment angles can ensure the straightness, maneuverability and recovery of the transmission system of the vehicle, prevent the rolling bearing from being damaged and losing precision due to improper bearing force, and ensure that the tires are closely connected with the ground, reduce improper tire wear, and ensure the stability of the vehicle when turning.
The purpose of the through-type 4-wheel alignment instrument is to use the alignment angle to measure and detect the above discomfort symptoms of the vehicle and give control. It is divided into front wheel alignment and rear wheel alignment. The front wheel alignment includes the kingpin caster angle, kingpin inclination angle, front wheel camber angle and front wheel toe. The rear wheel alignment includes the wheel camber angle and rear wheel toe. Under normal circumstances, a new car should be aligned after 3 months of driving. After that, the tires should be replaced every 10,000 kilometers. If there is a collision, the 4-wheel alignment should be done in time.
The above mentioned the necessity of vehicle 4 wheel alignment. Now let's talk about the issues that need to be paid attention to when doing 4 wheel alignment. When choosing a car maintenance shop, you must choose a professional one. Only technicians with practical experience and technology can provide the best service for your car with advanced 4 wheel alignment instruments. With the evolution of the suspension system from simple to complex, its structure is becoming more and more complicated, and the corresponding standards for 4 wheel alignment angles are getting higher and higher. Therefore, 4 wheel alignment instruments specified for certain types of models have appeared. The 4 wheel alignment instrument is not an instrument for adjusting and changing the alignment angle. It is only used to measure the alignment angle. Then, the technician uses this as a reference, compares it with the angle set by the original factory, and adjusts and changes the alignment angle to restore it to the original design angle.
