Of the car changing a wheel to fixed position is to point to turn to a wheel, turn to the axis before the section is mixed 3 person between the setup that has proper opposite place, call front-wheel drive fixed position again. Front-wheel drive fixed position includes advocate annul tilting back ward, advocate sell extroversion of batter, front-wheel drive and front-wheel drive toe-int 4 content, its action is the linear travel that maintains car stability and change direction light, after assuring to change direction, change direction annulus can answer automatically, reduce a car to be mixed in the tire in travel those who turn to parts wear away.
Turn to a wheel to locate the drill to the car charges a sex the influence is great. General car go is fair after course of development, appear likely sideslip, shake, steering wheel frame-up, tire slants grind wait for a circumstance, this kind of circumstance is a car commonly is four-wheel fixed position produced change, among them the change that the commonnest is toe-int. The action of toe-int is the front-wheel drive that eliminates front-wheel drive extroversion to cause outward scram trend, reduce tire to wear away. The symptom with the most apparent car after so toe-int is changed is tire slants grind. Bringing about toe-int to alter main reason commonly is to turn to ball head to wear away Song Kuang.
Advocate annul batter and advocate sell tilting back ward to have make change direction annulus answer automatically, carry car the action of linear travel, their distinction is advocate sell tilting back ward time action and speed are concerned, and advocate sell batter time action has nothing to do with speed almost. Accordingly, the car is when high speed travel of tilting back ward time effect is big, and basically lean when low speed travel answer since batter action. In addition, when linear travel, change direction annulus now and then when be pounded and producing deflexion, basically also lean advocate annul answer since batter action. So, when yours car happening changes direction to be answered not heavily, automatically when waiting for breakdown, it is these two parameter produced change commonly. The main reason that causes change of these two parameter is suspension is out of shape, each are decreased brace up decrease brace up glue covers Song Kuang; Glue of the pedestal on loose free from worries of head of pull rod ball, vibrating absorber covers damage or be out of shape etc.
The action of front-wheel drive extroversion is the security that enhances front-wheel drive job is mixed change direction operate light sex, the car when it produces change will be automatic sideslip. Some people change one's costume or dress his car, the wheel is become outside character 8, this kind of circumstance belongs to a wheel to lose extroversion. The main effect that such changing one's costume or dress is a car linear when high speed travel stability is better, won't easily sideslip, suit to quicken contest point-blank particularly so. But after this kind changes his costume or dress, change direction unusually heavy, everyman cannot control.
For the model that introduces independent suspension or rear wheel drive to rear wheel, the fixed position of rear wheel also is very important. Nevertheless the fixed position of rear wheel basically is rear wheel toe-int and horn of rear wheel extroversion, it can increase the lateral stability of the car, reduce tire wear away; There still is part of a thrust for car of the drive after be opposite, its action is to make sure the driving force of the car agrees with travel direction from beginning to end, avoid transverse drive a car. Usually thrust horn is 0, when system of suspension of two rear wheel is abhorrent, the thrust horn of the car can produce change.
So, of the car four-wheel the important parameter that fixed position is travel system, its correct, decided the travel security of the car and stability directly. If sideslip happens in car travel, hit direction to be answered not automatically annulus, overweight or steering wheel is float quiver, around tire odd side slants grind, the spare parts of car bridge and suspension once was torn open to install, or when the car creates the situation such as the injury of chassis and suspension because of the accident, we should be done in time four-wheel fixed position, adjust wheel parameter, charge a sex in order to maintain the drill with good car. And change tire, filling embryo commonly to wait, do not involve wheel fixed position, need not adjust so.
