Problems solved by technology

On the one hand, lubricating oil is required for the metal side bearing plate. The lubricating oil is imported special lubricating oil, which is expensive and not conducive to reducing consumption. Moreover, the amount of lubricating oil added is difficult to match the required friction coefficient.
At the same time, oil is used as a lubricant, which can easily make the friction coefficient between materials fluctuate greatly and be unstable, which brings hidden dangers to the safety of the locomotive.

Abstract

The invention relates to a self-lubricating non-metallic side bearing plate prepared from a material for the self-lubricating non-metallic side bearing plate. The self-lubricating non-metallic side bearing plate comprises a plate main body, and a mosaic block, wherein the plate main body is formed by the material for the self-lubricating non-metallic side bearing plate; the mosaic block is formed by teflon materials, and is embedded on the upper surface of the plate main body. By adopting the side bearing plate provided by the invention, an appropriate turning resistance moment is formed between a bogie and a car body, so that a shaking snake-shaped motion of the bogie and the car body caused by an oil-lubricating metal side bearing plate is effectively restrained; a side rolling vibration of the car body is restrained; the stationarity and the stability of a dynamic track stabilizer when running at a high speed are improved; the curve passage capacity is not affected; the mechanical requirements of bearing are also met.

Description

technical field [0001] The invention relates to a side bearing plate, more specifically, to a self-lubricating non-metallic side bearing plate and its material and production process. Background technique [0002] A side bearing plate is arranged between the bogie and the carriage of the railway freight car or road maintenance engineering vehicle, and the side bearing plate is in direct contact with the carriage. When the train turns, the side bearing pan moves along with the bogie, and the carriage will move to the other side of the train due to inertia, so there needs to be a suitable turning resistance distance between the bogie and the car body, and the turning resistance distance is too large , easily cause the train to roll over. If the slewing resistance distance is too small, the lateral force on the contact surface will increase, which will increase the lateral acceleration of the bogie and cause the vehicle to shake its head and snake. The main factor affecting ...
