Bogie and railway wagon with axle temperature detection and monitoring function

Abstract

The invention provides a bogie with a bearing temperature detecting and monitoring function and a railway wagon. The bogie comprises an axle and a bearing temperature monitoring device which is used for monitoring the temperature of a bearing, wherein an adapter is installed on the axle, the bearing is arranged between the adapter and the axle, a side frame is installed on the adapter in a snapping mode, a position where the side frame is snapped in the adapter is padded with an axle box rubber cushion, the bearing temperature monitoring device comprises a temperature sensing contact, the temperature sensing contact is electrically connected with a metal conduction hose, and the temperature sensing contact is arranged close to the bearing. The bearing temperature monitoring device collects temperature signals of the bearing which is arranged on the axle in real time and transmits the temperature signals to a control system of a railway vehicle and / or a dispatching center through a corresponding circuit, so that workers can know the temperature of the bearing in real time and judge whether the temperature reaches or is close to a warning temperature of a hot box or severed axle fault according to the temperature, if the temperature reaches or is close to the warning temperature, the front-station stopping or emergency stopping treatment is performed correspondingly, and hot box and severed axle faults caused by continuous increase of the temperature are avoided.

Description

technical field [0001] The invention relates to rail transit vehicle technology, in particular to a bogie and a railway freight car with axle temperature detection and monitoring functions. Background technique [0002] Increasing the axle load to increase the load is the development trend of the world's railway wagons. In recent years, my country's railway wagons have continuously increased their running speed under the premise of adapting to the overall speed increase of passenger cars. At the same time, the axle load has also been continuously increased to improve the transport capacity and meet the requirements of the rapid development of the national economy. Except for some high-speed trains running on passenger-dedicated lines in our country, the rest of the railway lines are mixed passenger and freight. Therefore, with the increase of speed and the continuous increase of axle load, the safety performance requirements for the operation of railway freight cars are gett...

AI Technical Summary

Problems solved by technology

At present, my country's railway freight cars can only monitor the bearing temperature through the axle temperature detection system at the station and the monitoring point, which makes the monitoring of the axle temperature not real-time and continuous. If the railway freight car runs between the two monitoring points, When the axle temperature rises abnormally, neither the driver of the railway freight car nor the railway dispatcher can know the abnormal temperature of the axle, and it is impossible to stop the front station or emergency stop accordingly. Then, as the railway freight car continues to run, the axle The temperature will rise further, and after the shaft temperature reaches a certain range, there will be hot shaft and shaft cutting faults
