Description

Nylon rail wheel with conducting ring

Technical Field

The utility model relates to a railway auxiliary vehicle rail wheel technical field, concretely relates to take nylon rail wheel of conducting ring.

Background

The auxiliary vehicle of the railway is a vehicle for overhauling and maintaining the railway, the overhauling and maintaining of the railway is a special 'skylight', namely a term used in the construction of business lines in the railway, because the running diagram of a railway train is uninterrupted in 24 hours, along with the increase of the train density and the load capacity, the former way of maintaining the line between the running time of a front train and the running time of a subsequent train cannot meet the requirement of the safe running of the train, the time of dividing 90-180 minutes every day for line maintenance is fixed on the running diagram of the continuous train in 24 hours specified on the running organization of the train, the train is maintained without running (namely, the division of construction and transportation work), thus, the quality of the line is improved, the running safety of the train is ensured, unsafe factors caused by the construction to the running of the train are reduced, and thus, the space for not opening the train is provided in the running diagram of the train, the railway is called as a construction skylight, and the skylight time is gradually backwards station by station according to the running direction of the train, so that the train can run conveniently, and the phenomenon of running interruption of the national railway train can not be caused. However, the "sunroof" time is usually short, and in order to do more lives in the limited "sunroof" time, the auxiliary vehicle is generally light and small, and the auxiliary vehicle can be placed on the rail of the railway as soon as the "sunroof" is opened, and can be moved away from the rail of the railway as soon as the "sunroof" is finished, so that the time is utilized to the maximum.

This requires that the wheels of the auxiliary vehicles are very light and lightweight, and since the polymeric material has both relatively high strength and wear resistance and is lighter than the metallic material, many of the wheels of the conventional railway auxiliary vehicles are made of polymeric material, but the wheels used in the conventional railway tracks are not allowed to be made of insulating material, and one wheel must have a conductive function. When nearby railway locomotives pass through at high speed, strong induced electricity can be generated on the locomotive body instantaneously under the action of the magnetic field. The conductive wheels can lead the current into the ground, so that electric shock accidents of personnel on the rail car are avoided. In the past, conductive wheels are all made of metal and are heavier in weight, and later, the conductive wheels are developed by placing conductive rings into a mold and molding nylon by casting to enable the conductive rings to be embedded into nylon wheels to form the conductive nylon wheels; the conductive rubber has high cost and strict requirement on the external dimension and is difficult to process.
