Calibrating apparatus for portable vehicle four-wheel position finder rotation angle disk

Abstract

The present invention discloses a calibrating device of the portable vehicle four-wheel position finer corner disk. The aim of the invention is to provide a special device for execute whole calibration to the four-wheel position finder corner disk of the vehicle and fill up the vacancy of the equipment in this aspect. The calibrating device is composed of a base supporting part (1), a column rotating axis part (2), a four-bar mechanism part (3) and a pressing measuring part (4). The column rotating part (2) is perpendicularly installed on the base (5) in the base supporting part (1) with the mode of rotating relative to the base supporting part (1), the four-bar mechanism part can be installed on the upper end of the column (8) in the column rotating axis part (2) with the mode up-and-down rotating relative to the column rotating axis part (2), the pressing measuring part (4) is fixed on the plane of the longitudinal oscillating arm (19) of the four-bar mechanism part (3), and the revolving axis of the pressing measuring part (4) is parallel with the revolving axis of the rotating axis part (2) after installation. The calibrating device has the advantages of low cost, high precision, strong adaptability and convenient using.

Description

technical field [0001] The present invention relates to a test device for automobile testing equipment applied in the field of automobile industry, more specifically, it relates to a test device for a portable four-wheel aligner corner disc Background technique [0002] The car's handling stability and straight-line driving performance are guaranteed by the reasonable matching of the car's wheel alignment parameters. Any misalignment of the parameters will cause the car to lose its handling stability and straight-line driving ability, accelerate tire wear, increase fuel consumption, and reduce safety And other issues. [0003] The four-wheel aligner is the most important testing equipment for checking wheel alignment. At present, there are more than 30,000 four-wheel aligners in the country, and they are increasing at a rate of 30% per year. However, no matter whether it is the production process or its use, the performance of the four-wheel aligner cannot be effectively te...

AI Technical Summary

Problems solved by technology

The detection of the above parameters by the four-wheel aligner can be realized by different detection methods and sensors, because the caster angle and the inclination angle of the kingpin cannot be directly measured by the sensor of the four-wheel aligner, but indirectly measured by the corresponding mathematical model , so it is extremely difficult to test the detection accuracy of different four-wheel aligners

[0007] At present, there is no special device for comprehensive verification of the corner disc of the automobile four-wheel aligner.
