The current after China's auto market is more confusing, real to the enemy accessories, maintenance or quality assurance is a common phenomenon, I believe these are the car owners know, and even some owners have suffered, but could do nothing, after all cars routine repair and parts replacement requires a certain expertise, ordinary car owners is difficult to understand the mystery. In order to avoid as much as possible allows you to cut corners, we deliberately correct procedure and method of operation of a vehicle wheel alignment explain explanation today.

What is wheel alignment

Each of four tires of a car, a steering mechanism mounted between the front and rear axles and having a certain relative position, the relative position of the vehicle manufacturers to the standard value is set. After a long daily driving time, the value of the standard factory settings may change, which we need to be corrected by the wheel alignment.

Wheel alignment, as the name suggests is the car's rear wheel alignment and positioning. Wherein the front wheel comprises positioning the caster angle, kingpin angle, camber and wheel toe four content; comprising positioning wheel camber and wheel toe individually. Here we carry out analysis of various angles of the front wheel alignment. (Typically positioned mainly in a vehicle tire wheel, the rear wheel is positioned less than normal, and after some overhang structure does not have to adjust the conditions, such as non-adjustable torsion beam rear suspension.)

Kingpin, in fact, no longer exists in many independent suspension on the vehicle, but the positioning has been used in the wheel of this word, but the kingpin is substantially representative of the steering wheel when the steering rotational center.

Caster angle

I.e., the upper end of the kingpin slightly backward tilt angle formed by the perpendicular wheel center. Its main role is to increase straight running stability of the vehicle and the rear of the front wheel steering can be self-aligning. The larger the angle of the caster angle, the better the running stability of the vehicle, the direction of aligning more obvious, but the steering wheel from the more laborious, but the current technology to assist steering by a depot in caster angle designed to be more large, without effort will turn the steering wheel.

Kingpin inclination

I.e., the upper end of the kingpin slightly inward tilt angle with the vertical center of the front wheel is formed. Like the rear caster, the caster to the same vehicle running stability and aligning forces designed.

Camber

I.e. camber angle formed outwardly perpendicular with the ground. It may be a case where the vehicle load, the tire contacts the ground at a better angle, the tire ground contact area greater call. Out inclination to spend big or too small may have resulted in bias tire wear, we called "bite-child" phenomenon is the camber angle and the size.

Toe

I.e. lateral spacing parallel to the front end of the two rear tires is smaller than the spacing. The above-mentioned outer wheels cause the wheel is poured flared state, will affect the parallel rolling wheels, and the role of the toe is offset by the disadvantages caused by the wheel camber.

Wheel alignment Under what circumstances

From the above article on analysis of wheel alignment, wheel alignment, we can understand the vehicle driving stability, steering back positive, and the ground angle of the tire and the ground area plays a big role. But with the everyday use of the vehicle, the relative positions of the four tires (standard value) go awry, but this time we need in a timely manner to a vehicle wheel alignment. According to the manufacturer's recommendations, with twenty thousand km per vehicle will be a wheel alignment, in order to prevent the deviation of wheel alignment values ??cause uneven wear of the tire and the vehicle running situation of instability occur.

Of course, if the vehicle deviation phenomenon occurs, there eating tire tire phenomenon, after repair or replacement chassis and suspension components, wheel alignment should be timely, in order to eliminate the influence of deviation value of the vehicle wheel alignment and tire caused.
