Embodiment Construction

[0037] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0038] The invention has the function of simulating the rotation of the automobile wheel on the corner disc, and can read the actual corner disc of the wheel aligner through a high-precision encoder, and the size of the simulated wheel corner can be read directly, and the accuracy of the inspection device is higher than that of the wheel The detection accuracy of the corner disc of the wheel aligner can meet the requirements of the national quality supervision department and the manufacturer for rapid on-site verification of the quality of the corner disc of the wheel aligner.

[0039] The present invention adopts the pressure spring to quickly generate downward pressure when checking the corner disc of the four-wheel aligner, and guides it through the through hole of the sleeve, so that when the support moves downward, its active force acts vertically on the rota...

Abstract

The invention discloses a quick calibrating apparatus for a turning disc of an automobile wheel positioning instrument, aiming at solving the problem that the turning disc of the automobile wheel positioning instrument can not be rapidly and accurately calibrated. The quick calibrating apparatus for the turning disc of the automobile wheel positioning instrument comprises a compression bar (1), asleeve (2), a base (3), a pressure spring (4), a stud (5) provided with a hole, a support seat (6), a bearing seat (7), a rotating shaft (8), a pressure plate (9), an elastic rubber pad (10), an encoder (11), a locating bolt (12), a bearing end cover (13) and a bearing (14). The quick calibrating apparatus can be used for completing the quick calibration for turning disc of the automobile wheel positioning instrument.

Description

technical field [0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to a quick verification device for a corner disc of an automobile wheel aligner. 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] Wheel aligner is the most important testing equipment for checking wheel alignment. At present, there are more than 200,000 wheel aligners in the country, and they are increasing at an annual rate of 30%. Ensure the detection accuracy of the wheel aligner itself. [0004] The wheel aligner corner plate is the main accessory of the wheel aligner. [0005] The measurement of ...
