Method for identifying tire profile of deviation angle of axel arranging and device thereof

Abstract

The invention belongs to performance inspection equipment of automobile headlights, relates to a method for identifying tire profile of deviation angle of axel arranging and a device thereof. In the method, a laser distance meter is used for scanning a tire to obtain profile curve of the tire and calculate the deviation angle of an automobile to be inspected. The device mainly comprises double guide rails (A), a base assembly (B), a stroke device (C) and the laser distance meter (D); wherein, the base assembly (B) is fixedly connected with the stroke device (C) to form an integral part; the base assembly (B) is mounted on the double guild rails (A) via a foundation wheel (11); a drive wheel of the foundation wheel (11) is driven by a drive mechanism; the laser distance meter (D) is mounted on the stroke device (C) and driven by a motor to move linearly; the start / end scanning points of the laser distance meter (D) is accurately positioned through a wire sensor. The invention aims at inspecting the included angle between automobile rear axle axis and light meter guild rail when the automobile is inspected to revise the inspection result of headlights.

Description

technical field [0001] The invention belongs to performance testing equipment for automobile headlights, and relates to a method and device for identifying the tire profile of the deflection angle of the axles, which overcomes the inaccurate measurement results caused by the technical situation of detecting headlights based on the axis of the vehicle body on the current automobile inspection line. exact question. The deflection angle of the driving direction is measured by the device, and then the detection result of the headlight is corrected. Background technique [0002] When driving at night, the technical condition of the headlights is very important to driving safety. In the new GB7258-2004 standard, it is proposed to use the vehicle alignment device to align the detected motor vehicle with the headlight detector according to the specified distance when testing with the headlight detector. The proposal of this standard also confirmed that in the detection of headligh...
