High-speed train carriage axle

Abstract

The invention relates to the technical field of train components, and concretely relates to a high-speed train carriage axle. The carriage axle comprises an axle body, a temperature control assembly,an electric air bag and a thermal induction color changing ring layer, a first circular groove penetrates through the shaft body in the central axis direction of the shaft body, a set of second circular grooves symmetrically penetrate through the shaft body with the central axis of the shaft body as the symmetry axis, the temperature control assembly comprises a driving assembly and a temperaturesensor, the driving assembly comprises cooling type semiconductor refrigerating devices and heating type semiconductor refrigerating devices which are the same in number, model and shape, electric airbags are arranged at the end portions of the two ends of the shaft body, the outer side wall of the shaft body is evenly coated with a plurality of thermochromic ring layers in the direction of the central axis of the shaft body, and each thermochromic ring layer comprises a group of thermochromic layer blocks of which the critical temperatures are gradually increased and the central angles are equal along the round edge direction. The problems of high detection difficulty, no dynamic temperature control capability and the like in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of train components, in particular to an axle of a high-speed railway carriage. Background technique [0002] High-speed trains often cause train damage, train failures, and even major train derailment accidents when they are serious due to the excessive temperature of the train axles during travel. Therefore, in order to avoid train accidents, a vehicle inspection and maintenance station will be set up along the railway line. A large number of railway workers use manual methods to detect the state of the train axle. The method requires a large number of railway workers to detect the state of the train axle, requires a large amount of manpower and material resources, and correspondingly increases the labor cost. [0003] In order to reduce labor costs, infrared detection is often used to measure the temperature of train axles at present, that is, infrared probes are installed at certain intervals along the ...

AI Technical Summary

Problems solved by technology

[0006] First, the detection difficulty is relatively high, because the detection personnel still need to read the detection value of the sensor through the corresponding electronic device, but cannot directly and quickly judge the temperature of the axle;

[0007] Second, it does not have the ability of dynamic temperature control, because it only has the ability to detect the temperature of the axle, but does not have the ability to effectively control the temperature of the axle
