Multifunctional intelligent detection and diagnosis integrated equipment for automobile chassis

Abstract

The invention discloses multifunctional intelligent detection and diagnosis integrated equipment for an automobile chassis. The multifunctional intelligent detection and diagnosis integrated equipment comprises the following contents: A, determining whether wheels reach or leave a detection position by adopting a weight identification method; B, adopting a method of automatically moving and correcting an automobile body at a low speed without a method of driving and correcting; C, adopting a separated remote control pedal switch for brake detection; D, adopting a device and a method for quickly stopping the wheels from laterally impacting the stand column back and forth; E, detecting parking braking force through a low-speed indirect detection method for measuring deceleration; and F, obtaining the braking coordination time and confirming whether the braking is emergency braking or point braking according to the braking deceleration curve change characteristics. The cost performance advantage is large, the detection workshop and the occupied area of an automobile detection enterprise are reduced in a multiplied mode, land resources are saved, a large amount of investment is saved, the detection charge can be reduced, the occupied area of automobile detection is small, and the vehicle owner can handle the vehicle inspection service more conveniently.

Description

technical field [0001] The invention relates to automobile chassis testing equipment, in particular to a counterforce type roller brake inspection platform, an axle load meter, a speedometer inspection platform, an inertia type roller brake inspection platform and a special remote control pedal switch for automobile braking. Background technique [0002] The current professional automobile inspection line usually has three types of inspection equipment: the reaction force roller brake inspection table (hereinafter referred to as the reaction table), the axle load meter and the speedometer inspection table. Among them, the reaction force table is used to test the wheels of the car The maximum braking force of the vehicle, and then judge whether the braking force is up to the standard according to the load of each axle; the axle load meter is used to weigh the load of each axle of the car, and provides data matching for the reaction table; the speedometer inspection table is us...

AI Technical Summary

Problems solved by technology

Since the inertial table came out in the 1960s, it has not been popularized due to many problems that restrict its use. The main problems are: ①, high-speed detection will generate serious noise; ②, the wheel is easy to sideways on the high-speed rotating drum ③, there is no remote pedal switch suitable for brake detection; ④, on-site safety issues for high-speed detection

[0005] 3. The professional automobile inspection line has computers to control each inspection equipment, instrument and inspection process, realizing digital display and automatic inspection of a single process, but so far there is no concept of intelligent inspection. Due to backward inspection technology and few inspection contents, The above-mentioned three types of equipment do not exceed four testing items in total, and are far from being a reference for the basic technical performance of the automobile chassis, let alone a diagnostic basis for analyzing and judging chassis technical faults

In addition, automobile chassis diagnosis is a matter of the automobile maintenance industry, and has never been related to the automobile inspection industry. The current technical level of automobile chassis diagnosis lags behind engine diagnosis, and it is still necessary to rely on traditional diagnostic instruments and people's technical experience to carry out different inspections on the chassis. Disintegration inspection, analysis and judgment, the whole process is manually operated, and the diagnosis conclusion is determined by the person, that is, it varies from person to person, so the diagnosis accuracy is poor and the work efficiency is very low
