Description
Technical field
The present invention relates to four-wheel aligner technical field, especially relate to a kind of 3D four-wheel aligner method of testing.The invention still further relates to a kind of 3D four-wheel aligner tester.
Background technology
The steered wheel of car, the installation between steering knuckle and front axle three have certain relative position, and this installation with certain relative position is called steered wheel location, also claims front alignment.Front alignment comprises reverse caster (angle), Kingpin inclination (angle), front wheel camber (angle) and toe-in of front wheel four contents.This is for two steering front wheels, concerning two trailing wheels, there is the relative position installed between rear axle too, claims trailing wheel location.Trailing wheel location comprises camber (angle) and trailing wheel is prenex one by one.Four-wheel aligner is in general in such front alignment and trailing wheel location.When vehicle uses for a long time, user finds that directional steering is heavy, shakes, sideslip, not just, non-homing or the irregular wear such as tire uneven wear, wavy wearing and tearing, block wearing and tearing, eccentric wear, and user is when driving, car sense is floating, jolt, the phenomenon such as to wave when occurring, just should consider to check wheel locator value, look at whether deviation is too many, places under repair in time.
Concretely, front alignment comprises kingpin castor angle, kingpin inclination, front-wheel camber and toe-in of front wheel four contents.Trailing wheel location comprises camber angle and trailing wheel is prenex one by one.That is: wheel from the side, pivot stud (rotation center during wheel steering) is toppled over backward, is called kingpin castor angle.After kingpin castor angle is set, produce distance between the earth point of king pin axis and the floor projection point of wheel center and (be called mechanical trail, identical with the sweptback principle of front fork beam of bicycle), the earth point of wheel is made to be positioned at the rear end of pivot stud extended line, wheel is just pulled rearward by the resistance to rolling in traveling, makes the direction nature of wheel towards travel direction.Set very large kingpin castor angle and can improve linear driving performance, mechanical trail also increases simultaneously.Mechanical trail is excessive, steering wheel can be made heavy, and aggravate pitching of wheel due to road agitation.Viewed from car fore-and-aft direction during tire, tilt inside the axial vehicle body of stub, this angle is called kingpin inclination.When wheel turns round centered by stub, the minimum point of wheel will be absorbed in below road surface, but in fact wheel lower limb can not be absorbed in below road surface, but steered wheel is upwards lifted a corresponding height together with whole automotive front, the gravity of such automobile itself has the effect making steered wheel be returned to original centre position, and thus bearing circle resets easily.In addition, kingpin inclination also makes main pin axis and road surface intersection point reduce to the distance of central plane of wheel and ground intersection, thus reduce driver when turning to and add power on the steering wheel, make handling maneuver light, also can reduce the impulsive force passed to from deflecting roller bearing circle simultaneously.But kingpin inclination is also unsuitable excessive, otherwise accelerates the wearing and tearing of tire.Viewed from fore-and-aft direction during wheel, tire is not at right angle setting, but topples over a little and present "eight" shape and open, and is called inward camber, and claims positive flare when opening in the opposite direction.Use the period of great prosperity of diagonal-ply tire, tilt to contact to earth owing to making tire and be convenient to the operation of bearing circle, so camber angle is established larger.Camber angle generally sets very little by automobile, close to vertical.Automobile dress is constantly popularized with flat radial, due to the characteristic (tyre tread rigidity is large, cover tire face width) of radial, if setting high camber angle can make tire grind partially, reduces Tire Friction.Also due to the continuous use of assisted power steering system, camber angle is also made constantly to reduce.However, set a little camber angle and can apply suitable horizontal thrust to the wheel bearing on axletree.Toes turned inward, the meaning of so-called " pigeon-toed ", refers to left and right front-wheel respectively to interior.This structure object is adopted to be that the wheel that the above-mentioned front-wheel camber of correction causes laterally rotates.As previously mentioned, owing to there being flare, steering wheel operation becomes easy.On the other hand, due to the tilting of wheels, left and right front-wheel laterally rotates respectively, and in order to revise this problem, if left and right two-wheeled is with inside angle, then positive and negative is zero, and left and right two-wheeled can keep straightaway, reduces tire wear.Four kinds of above-mentioned locator values are all the indexs of front alignment.Trailing wheel locator value is worth similar to front alignment, but the trailing wheel of most of car location is non-adjustable.
At present, common on market four-wheel position finder has prenex chi and optics level orientator, bracing wire orientator, CCD orientator, laser orientation instru-ment, the dynamic four-wheel position finder of computer (weighbridge formula) and 3D image orientator etc. several.Wherein, common 3D image orientator operation convenience in also there are some defects, so also there is a certain distance than the dynamic four-wheel position finder of computer in popularity.
