Abstract

The invention provides a portable trailer pneumatic braking response time integrated measuring device which comprises a simulation brake trigger, a tractor pneumatic circuit simulating device and a data acquisition device. The simulation brake trigger comprises a manual-controlled mechanical valve body and an accessory, and is connected with a tractor pneumatic circuit simulating device; the tractor pneumatic circuit simulating device comprises a gas storage device, a pipeline damping adjusting device and a pipeline pressure collector; a part of the pipeline pressure collector is fixed on theupper part of the tractor pneumatic circuit simulating device and is connected with the air storage device, and the other part is connected with the brake air chamber of the tested trailer. The pipeline pressure collector is connected with the data collector through an analog input channel. The data collector is also connected to the upper computer. The invention is convenient to carry, high in integration, fast and accurate in data analysis and processing, greatly improves the working efficiency of the response time measurement of the trailer pneumatic braking system, and greatly enhances theconvenience of the test work.

Description

technical field [0001] The invention belongs to the technical field of vehicle detection, and in particular relates to a portable trailer air pressure brake response time integrated measurement device. Background technique [0002] Braking performance is an important indicator of the performance of the trailer, and the braking response time of the trailer represents the speed at which the trailer responds to the brake pedal operation of the tractor, which directly affects the braking distance of the trailer and the braking distance between the tractor and the trailer. coordination. The national mandatory standard GB12676-2014 "Technical Requirements and Test Methods for Brake Systems of Commercial Vehicles and Trailers" clearly stipulates the test methods and limit requirements for trailer brake response time. At present, the traditional test device uses a metal frame as the main pipe to connect the air tank and the simulated air circuit, connect it to the air brake pipelin...
