Embodiment

[0029] Referring to Fig. 1, detection device of the present invention comprises signal detection system A, electrical control system B, mechanical system C and microcomputer processor D, and its concrete composition and effect are as follows:

[0030] (1) Signal detection system

[0031] Including the stroke signal of the hydraulic cylinder measured by the displacement sensor and the air pressure signal measured by the high-precision pressure sensor, the signal detection system consists of a PCL-818 data collector with A / D function, a PCLD-8115 signal conversion terminal board, a displacement sensor, two pressure sensors. Specific working process:

[0032] ①. The displacement sensor converts the engineering displacement into the corresponding analog current; the pressure sensor converts the engineering air pressure into the corresponding analog current.

[0033] ②. The PCLD-8115 signal conversion terminal board completes the signal conversion and connection between the displ...

Description

technical field [0001] The invention relates to the detection technology of the buffering and damping springs of the bogies of railway passenger transport vehicles, in particular to an air spring detection device for express passenger cars and its technology. Background technique [0002] With the rapid development of passenger car bogie technology in my country in recent years and the introduction of a large number of foreign advanced high-tech passenger car vehicles, the number and types of air springs are increasing. Performance, safety, and comfort play an important role. Whether the quality of the air spring can be tested comprehensively and accurately will directly affect the driving safety of the vehicle. Because the air spring has high requirements on wind pressure and air tightness, the air tightness detection and judgment of the air spring in the prior art lacks integrity, and the method of relying on the manual observation of the pressure gauge lacks accuracy; in a...
