Fully computerized locator of trailer and measurement method thereof

Abstract

The invention relates to a fully computerized locator of a trailer and a measurement method thereof. The locator comprises a spindle nose 1, a spindle nose 2 and a traction pin centering measuring device. The measurement method requires that a camber angle alpha=(A-B)*C is measured, then distance s=vt is measured, and in addition, lateral displacement L=(E-F)*G is also measured. According to the locator and the method, the detection and adjustment process of the trailer is clearer, the equipment operation is simpler and more convenient, the fact that the trailer location is not the problem that the length is simply measured can be intuitively reflected, the working efficiency of trailer detection and adjustment is further increased, and the labor strength of handlers is reduced.

Description

technical field [0001] The invention relates to a full computer locator for a trailer and a measuring method thereof. In particular, it relates to an ultrasonic full computer locator for a trailer and a measuring method thereof. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal or vertical forces to the tractor. It is mainly used to transport large and difficult to disassemble large parts goods. Compared with "single-body" cars, semi-trailers can better improve the comprehensive economic benefits of road transportation. [0003] Since the semi-trailer is a relatively special vehicle, the parallelism of the axle and the distance error from the center of the traction pin to the axle end directly affect the driving safety of the semi-trailer, and also directly affect the wear degree of the semi-trailer tire...

AI Technical Summary

Problems solved by technology

[0005] At present, the semi-trailer inspection products produced by domestic manufacturers mainly use laser range finders for distance measurement. And the lower position will cause inconvenient observation and thus cause man-made measurement errors, and because the scale line on the scale is thinner, it is slower to find the alignment, so the overall work efficiency is lower

In addition, as a non-standard dot, the laser point cannot completely guarantee that the scale line is on the center of the light spot when it hits the scale line, which will also cause measurement errors

[0006] On the other hand, the semi-trailer positioning products produced by domestic manufacturers generally ignore the detection of rim deformation and axle deformation, that is, the influence of rim out-of-round and camber angle changes on tire abnormal wear; international advanced detection Although the influence of these factors has been considered in the technology, the detection benchmark is mainly the large frame of the vehicle, not the traction pin, which is the key connection point between the trailer and the tractor. There is a certain deviation in the selection of the benchmark, and the main The mechanical structure is used for adjustment, so there are disadvantages of low precision and low work efficiency
