3d four-wheel aligner verification device and its synchronous drag frame device

Abstract

The invention discloses a 3D four-wheel localizer verification device and a synchronous dragging frame device thereof. The synchronous dragging frame device comprises a synchronous dragging frame and a synchronous frame limiting device, wherein the synchronous dragging frame comprises a cross rod, longitudinal rods and sensor jacket devices. The 3D four-wheel localizer verification device comprises a toe-in zero test frame, a front rack test portion, a rear rack test portion and the synchronous dragging frame, wherein the front rack test portion and the rear rack test portion are arranged on the toe-in zero test frame, and the synchronous dragging frame is respectively connected with a transverse shaft in the front rack test portion and a transverse shaft of the rear rack test portion in a locking mode through the four sensor jacket devices. Simultaneous rotation of four sensors is achieved, the actual work process that a 3D four-wheel localizer verifies the angle of wheels of an automobile is completely simulated, and 3D four-wheel localizer verification is achieved.

Description

technical field [0001] The invention belongs to the field of automobile testing equipment, in particular to a 3D four-wheel aligner verification device and a synchronous drag frame device thereof. 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 the wheel alignment parameters. At present, there are more than 30,000 four-wheel aligners in the country, and they are increasing at an annual rate of 30%. Ensure the detection accuracy of the four-wheel aligner itself.
