Description
Technical field the present invention relates to the verifying attachment of automotive inspection equipment, particularly relates to the verifying attachment of four-wheel position finder precision.
Technical background vehicle handling stability and roadholding are that the reasonable coupling by the automotive wheel positional parameter guarantees, any one misalignment of parameter just can cause automobile loss of control stability and the straight line property exercised, accelerate tire wear, degradation problem under the economy.
Four-wheel position finder is the most important checkout equipment of check wheel alignment.The recoverable amount of present national four-wheel position finder reaches more than 8000, and the speed with annual 30% is increasing progressively, no matter yet be its production run or its use, all can not effectively check at present the performance of four-wheel position finder, can't guarantee the accuracy of detection of four-wheel position finder itself.
Four-wheel position finder has multinomial function, as detecting camber angle, toe-in, kingpin castor angle, kingpin inclination and wheel steering locking angle, wrapping angle etc.Four-wheel position finder can be realized by different detection methods and sensor the detection of above-mentioned parameter, because kingpin castor angle and kingpin inclination can not directly be measured by the sensor of four-wheel position finder, but measure indirectly by corresponding mathematical model, so, it is just difficult unusually that different four-wheel position finder accuracy of detection are tested, at present, the verifying attachment that four-wheel position finder manufacturer uses only can be tested to the accuracy of detection that four-wheel position finder is measured camber angle and toe-in angle, and can not test to the precision that four-wheel position finder detects kingpin castor angle and kingpin inclination etc.
At present, the verifying attachment that does not also have a science completely examines the precision of four-wheel position finder itself.
Summary of the invention the objective of the invention is to solve existing verifying attachment and only can test to the accuracy of detection that four-wheel position finder is measured camber angle and toe-in angle, and can not detect the problem that the precision of kingpin castor angle and kingpin inclination etc. is tested to four-wheel position finder, a kind of four-wheel position finder verifying attachment that can completely examine the four-wheel position finder accuracy of detection is provided.
Above-mentioned purpose of the present invention is to realize like this, accompanying drawings is as follows: the four-wheel position finder verifying attachment is by camber and prenex adjusting mechanism, the Kingpin inclination adjusting mechanism, reverse caster adjusting mechanism and panoramic table adjusting mechanism are formed, camber and prenex adjusting mechanism, Kingpin inclination adjusting mechanism and reverse caster adjusting mechanism adopt the arc calibration and the vernier of three groups of correspondences respectively, kingpin inclination calibration 12 is fixed on the bracing frame 26 by its support bar, Kingpin inclination angular vernier 15 is hinged on the support bar of kingpin inclination calibration 12 by the rotating shaft on its support bar 25, kingpin castor angle is calibrated on the 18 vertical support bars that are fixed on Kingpin inclination angular vernier 15, reverse caster angular vernier 17 is contained on the stub axle 22, stub axle 22 is hinged on the support bar of Kingpin inclination angular vernier 15 by hinge 24, be sleeved on sleeve 23 on the stub axle 22 and connecting firmly the revolving shaft 5 of disk 1, disk 1 is hinged by hinge 3 with disk back up pad 2 lower ends in camber and the prenex adjusting mechanism, the upper end is equipped with camber respectively, prenex calibration and vernier 10,11, disk supporting plate 2 is contained on the revolving shaft 5 by the lock plate 6 of band gap, on revolving shaft 5, hang with the folding flap 30 that turns to, its lower end is the blade fin 29 that is contained in calibration panoramic table 27 gathering sills 28, kingpin inclination calibration and vernier 12,15, kingpin castor angle calibration and vernier 18,17, and camber, prenex calibration and vernier 10, can be in harmonious proportion locking between 11, its center of curvature is respectively by each axis of rotation 25,24,3.
The present invention designs by following know-why:
1) simulation camber angle principle: adjust caster, make the revolving shaft 5 of disk be in level, turn flare and prenex adjustment screw 8, then disk 1 promptly can change with respect to the angle of disk supporting plate 2, and the variable angle size is read by prenex calibration of the wheel introversion on disk 1 and the disk supporting plate 2 and vernier 10,11.
2) simulate the toeing-in principle: disk is revolved to turn 90 degrees by latch mechanism lock, realize the adjustment of toe-in according to the method for adjusting camber angle.
3) simulation kingpin inclination principle: kingpin inclination calibration 12 maintains static, and Kingpin inclination angular vernier 15 can rotate around the z direction of principal axis in the xy plane, and vernier and calibration relatively rotate angle and illustrate by scale.
4) simulation kingpin castor angle principle: kingpin castor angle calibration 18 maintains static on the z direction of principal axis, and reverse caster angular vernier 17 can rotate around the x direction of principal axis in the yz plane, and vernier and calibration relatively rotate angle and illustrate by scale.
5) demarcate kingpin castor angle and leaning angle principle: panoramic table 27 can be in the xz plane arbitrary angle rotary (in the angle of regulation), stir to turn to flap 30 and then stir other mechanism by the chute above it during rotation and turn an angle, final exercises when realizing that simulation wheel kingpin castor angle and leaning angle detect.
The present invention has the function of the various orientation angles of simulation wheel, the big I of its simulation wheel orientation angle is directly read, the precision of verifying attachment is higher than the accuracy of detection of four-wheel position finder itself, satisfies the quality arbitration to four-wheel position finder of manufacturer and national quality superintendent office.
