Dynamic four-wheel aligner method.
Background technology
After vehicle uses some time, user has found that directional steering is heavy, shakes, sideslip, not just, non-homing or wheel
Tire uneven wear, wavy abrasion, bulk abrasion, when the irregular wears such as eccentric wear and user drive, vehicle sense is floated, jolts, is shaken
When phenomena such as pendulum occurs, it should just consider to carry out four-wheel aligner, see whether that deviation is too many, place under repair in time.Wherein, it eats
Tire, sideslip and steering wheel are not exactly the most common problem and the key of four-wheel aligner adjustment.
First, it includes two kinds of situations to eat tire problem：
1. front-wheel eats tire：When toe-in of front wheel not clock synchronization, it may appear that wheel toed-in（As shown in Figure 1, L1<L2）Or toed-out
Shape（As shown in Fig. 2, L1>L2）, as shown in shadow region in figure, in wheel on the outside of eight emery wheel tires（Eroded area is A1 and A2）,
On the inside of the outer eight emery wheel tire of wheel（Eroded area is A3 and A4）.Since slight interior eight can enable vehicle performance flexible, turn to lighter
Just, so the wheel setting of normal vehicle is interior eight formulas.
In terms of front-rear direction when wheel, tire is simultaneously non-perpendicular, but slightly topples over and "eight" shape opening is presented, referred to as negative outer
Incline（As shown in Figure 3）, and while opening in the opposite direction claim positive flare（As shown in Figure 4）.The former grinds on the inside of wheel, and the latter grinds outside wheel
Side needs if angle is excessive plus eccentric screw adjusts.Substantially, positive camber angle is set with preferable flexibility ratio, and negative outer hectare
The relatively stable rectilinear propagation of angle tool.
2. trailing wheel eats tire：Trailing wheel also has toe-in value and inclination value.Trailing wheels value is similar to front wheel alignment value, trailing wheel inclination angle
Value should be advisable in negative camber angle, preventing vehicle from floating, jolting, waving, break away.Trailing wheel toe-in mutually seemingly should with toe-in of front wheel
Eight formulas in relatively.
Furthermore the problem of sideslip, then it is to belong to wheel tyre pressure to need to distinguish, tire wear or the not positive situation of steering wheel,
It is adjusted again.
Four-wheel aligner is one of required action of auto repair maintenance.Carry out four-wheel aligner promptly and accurately, can
