Description
Technical Field
The invention relates to the technical field of automobile detection, in particular to a contact type dynamic surface measurement four-wheel aligner.
Background
The aligner is a device for checking and adjusting toe-in camber of a wheel in order to ensure smoothness and operational stability during vehicle driving.
The existing four-wheel aligner is divided into two categories according to the measuring principle and the measuring object.
The current four-wheel aligner for a repair shop or a 4S shop belongs to the type of the chuck type four-wheel aligner which takes a hub as a measurement object statically. The principle is as follows: the static measurement point or the measurement of the position of the wheel hub during the moving process of pushing the automobile to move back and forth by 15-20 cm is taken as the wheel position, the wheel hub does not represent the wheel, the tire and the wheel hub are assembled to be called as the wheel, therefore, the position finder measures that the middle target is not the target of the wheel, the contact between the wheel and the ground during the running of the automobile is the final target, and the advantages and the disadvantages of the position finder are that: its advantage is low cost (tens to hundreds of thousands). The device is suitable for finding faults when the tires of the vehicle are abnormally worn or the vehicle deviates. The method has the defects that manual operations such as manual chuck installation on the hub of four wheels, leveling, focusing, front and rear cart pushing and the like are needed for detection, the chuck is not installed in place, the machining precision of the hub is affected, the measurement result is influenced, the repeatability is poor, the static positioning of the hub is not the dynamic positioning of the wheel, and dynamic deflection compensation of wheel rotation and correction of steering wheel deflection angle are not needed. The inspection and adjustment time is different from 20 minutes to one hour, the aligner of the static point measurement hub cannot inspect the rotation of the wheel, namely the dynamic positioning of the vehicle during running, the repeatability is poor, the dynamic deflection compensation of the rotation of the wheel is not realized, and the deflection angle of a steering wheel is corrected, so the inspection requirement of a car factory is not met, the beat is slow, and the bottleneck of offline inspection flow of the car factory is formed, and the four-wheel alignment is not suitable for offline inspection of a production factory.
The other type is a non-contact dynamic laser four-wheel aligner which dynamically takes a tire end face (target is a wheel) as a measuring object, and the principle is that the measurement is carried out when the wheel rotates: equivalent to measuring the true dynamic positioning of the wheels while the vehicle is running. His advantages and disadvantages: the method has the advantages that the positioning instruments truly reflect the dynamic positioning of the vehicle during running, can compensate the deflection of the wheels, correct the deflection angle of the steering wheel, automatically finish the inspection without manually installing a chuck, have the beat of not more than two minutes per vehicle, are the ultimate target object wheels, and are suitable for offline inspection and adjustment of an automobile factory. The defects are high price, 400-500 in case of one table is monopolized abroad, the maintenance cost is high, the charging is carried out when the maintenance is safe, the accessories are expensive, and the user often exclamates that the user cannot start to bite the teeth.
In order to solve the urgent need of customers, a contact type dynamic surface measurement four-wheel aligner is innovatively designed, the contact type dynamic surface measurement four-wheel aligner is used for measuring dynamic surface measurement of a vehicle running simulation platform, wherein a wheel is equivalent to a dynamic toe-in angle and a camber angle when a vehicle runs on a road, a laser measurement assembly of a non-contact type laser four-wheel aligner with high price is replaced by a contact type dynamic surface measurement four-wheel aligner with three rollers contacting with a tire end surface, the problem that an automobile factory with medium and small capacity cannot bear high purchase price of the non-contact type dynamic four-wheel aligner is solved, the aligner of the other extreme repair factory takes a wheel hub as a measurement object, the static toe-in camber of the measurement wheel hub is taken as the static alignment of the wheel, the key indexes that the dynamic alignment of the vehicle during running is not available, and the yaw compensation and the correction of a steering wheel are, the defects of the measurement principle and the slow beat are not suitable for the offline inspection of the production. The contact type dynamic four-wheel aligner inherits the advantages of the dynamic measurement principle of the non-contact type four-wheel aligner, overcomes the defect of high price of a laser measurement assembly, and essentially greatly surpasses a chuck aligner for static point measurement, so that the blank of a middle-grade through type dynamic four-wheel aligner is filled up, the contact type dynamic surface measurement four-wheel aligner can meet the detection and adjustment requirements of a car factory, the beat, the measurement principle and the functions are completely the same as those of the non-contact type four-wheel aligner, and the contact type dynamic four-wheel aligner can be switched to the non-contact type four-wheel aligner according to the requirements of.
