Description
technical field
[0001] The invention belongs to the field of rail vehicle frame devices, in particular to a horizontal and vertical integrated non-dynamic frame device with a temperature-measurable axle box. Background technique
[0002] In the design of rail train bogies, it is not only necessary to comprehensively consider the structural strength and flexibility of the frame as the main body of the load, the effect of various auxiliary vibration damping components such as anti-snake shock absorbers, and the installation method of the braking mechanism. According to the requirements of different models, the structural form of the primary suspension is comprehensively designed according to the theoretical speed of the train, the load-bearing load, the minimum curvature of the curve and the road conditions such as wind, snow and flying rocks. Various design schemes based on the above-mentioned core ideas have been increasingly improved and complicated, which eventually led to...
