Self-adaptive adjustment method for truck brake table and roller brake table for detection

Abstract

The invention relates to the field of vehicle detection devices, and particularly discloses a self-adaptive adjustment method for a truck brake table and a roller brake table for detection. The methodcomprises the steps that S1, a program is preset according to different vehicle types to determine the positions, needed by the corresponding vehicle types, of roller units on a roller brake table; S2, a subsystem I selects a preset program according to the vehicle model and transmits a signal to a subsystem II; S3, the subsystem II adjusts the position of the roller unit according to the signalof the subsystem I; S4, when detecting that a corresponding limiting switch is triggered, a subsystem III transmits a signal to the system II to enable a corresponding electromagnet to be powered off;S5, a coupling system detects electric signals of an electromagnet, an electromagnetic clutch and the limiting switch in real time and judges whether the roller unit is in place or not; and S6, the vehicle is placed on a brake table to be detected, and detected data are obtained. The method has the advantages that the position of the roller unit can be changed to adapt to different vehicle types,and the adaptability of the device is improved.

Description

technical field [0001] The invention relates to the field of vehicle detection devices, in particular to an adaptive adjustment method for a truck braking platform and a detection roller braking platform. Background technique [0002] According to the implementation regulations of China's Road Traffic Safety Law, trucks and large and medium-sized non-operating passenger vehicles shall be inspected once a year within 10 years, and once every 6 months if they exceed 10 years. Traffic accidents, so it is necessary to regularly detect the braking force of the car. During the inspection, it is necessary to use a brake table to detect the braking performance of the car and the condition of the vehicle wheels. The existing roller detection table has limited rollers, and It is a fixed setting. Because the wheel distribution and the distance between the wheels of different models are different, it is necessary to use the brake table to adapt to different models. It has achieved the p...

[0002] According to the implementation regulations of China's Road Traffic Safety Law, trucks and large and medium-sized non-operating passenger vehicles shall be inspected once a year within 10 years, and once every 6 months if they exceed 10 years. Traffic accidents, so it is necessary to regularly detect the braking force of the car. During the inspection, it is necessary to use a brake table to detect the braking performance of the car and the condition of the vehicle wheels. The existing roller detection table has limited rollers, and It is a fixed setting. Because the wheel distribution and the distance between the wheels of different models are different, it is necessary to use the brake table to adapt to different models. It has achieved the purpose of testing multiple models with one brake table. The current brake table cannot be used. The detection of various vehicle models requires multiple devices for detection, wasting resources
