Verification device based on belt-driven four-wheel aligner

Abstract

The invention discloses a four-wheel aligner calibrating device based on belt drive. The four-wheel aligner calibrating device aims to solve the problem that quality arbitration cannot be carried out on a 3D four-wheel aligner. The four-wheel aligner calibrating device comprises a toe-in zero-point test frame, a front rack test portion, a rear rack test portion, a right belt drive device and a left belt drive device. The left belt drive device comprises a driving pulley, a front driven pulley, a front sensor clamping sleeve, a rear sensor clamping sleeve, a rear driven pulley and a belt. The outer end of the long ground foot wheel shaft of a front left combined supporting leg in the toe-in zero-point test frame is sleeved with and in key connection with the driving pulley, the left end of a front cross shaft in a left rack test portion is sleeved and locked with the right end of the front sensor clamping sleeve, the middle portion of the front sensor clamping sleeve is sleeved with the front driven pulley which is in key connection, the left end of a rear cross shaft in a left rack test portion is sleeved with the right end of the rear sensor clamping sleeve which is locked, the middle portion of the rear sensor clamping sleeve is sleeved with the rear driven pulley which is in key connection, and the belt is arranged in the pulley groove of the driving pulley, the pulley groove of the front driven pulley and the pulley groove of the rear driven pulley.

Description

Technical field [0001] The invention relates to an automobile testing equipment used in the automobile industry, and more specifically, it relates to a belt-driven four-wheel aligner verification device. Background technique [0002] Car handling stability and straight-line driving performance are guaranteed by the reasonable matching of car wheel positioning parameters. Any inaccuracy of the parameters will cause the car to lose handling stability and straight-line driving ability, accelerate tire wear, increase fuel consumption, and reduce safety. And other issues. [0003] The four-wheel alignment device is the most important testing equipment for testing wheel alignment parameters. At present, there are more than 30,000 four-wheel aligners in the country, and it is increasing at an annual rate of 30%. However, it is difficult to effectively test the performance of the four-wheel aligner in both its production process and its use process. Ensure the detection accuracy of the f...

Problems solved by technology

[0038] The technical problem to be solved by the present invention is to overcome the problem in the prior art that the quality inspection of the 3D four-wheel aligner widely used in the market cannot be realized, and to provide a device with the functions of simulating the synchronous rotation of automobile wheels and various positioning angles. Higher than the detection accuracy of the 3D four-wheel aligner, it can meet the requirements of the national quality supervision department and the manufacturer for the on-site rapid verification of the quality of the 3D four-wheel aligner. The verification device based on the belt-driven four-wheel aligner
