Wheel flange lubrication control method based on position information

Abstract

The invention discloses a wheel flange lubrication control method based on position information. The wheel flange lubrication control method based on the position information comprises the steps of subway vehicle running path presetting; trackside signal equipment laying, vehicle running position confirming, curved turning judging and wheel flange jet lubrication, wherein the wheel flange jet lubrication comprises a wheel flange lubrication system activation step, a flat road lubrication jet step and a curve lubrication jet step. When a wheel flange lubrication system is determined as an activated state and a vehicle is positioned in a curve turning position, a vehicle control system VCU transmits a jet instruction to the wheel flange lubrication system; after receiving the jet instruction, the wheel flange lubrication system carries out wheel flange jet lubrication according to the curve jet requirement; and the jet amount in the curve jet requirement is larger than that in the flat road jet requirement. The wheel flange lubrication control method based on the position information has the advantages that the desired jet position can be accurately positioned, system delay is reduced, the false jet frequency is reduced, the wheel flange wear is obviously reduced, the use time of a wheel is prolonged, the wheeltrack noise is reduced, the running resistance is reduced, the running cost is obviously saved and the social benefit is increased.

Description

technical field [0001] The invention relates to the control field of a wet wheel rim lubrication system for urban rail transit vehicles, in particular to a method for controlling wheel rim lubrication based on position information. Background technique [0002] Since 1863, when the first subway recognized in the world was put into operation, urban rail transit in the form of steel wheels and rails has occupied a dominant position. The problem of rail side wear, especially in the case of lines with more curves, the wear of the rim is more serious. In order to solve and alleviate the wear problem of steel wheels and rails, rim lubrication technology has emerged as the times require. At present, there are mainly two rim lubrication methods, one is called dry rim lubrication, and the other is wet rim lubrication. [0003] The lubricating block for dry wheel rim lubrication keeps in contact with the wheel rim at all times, and it is always in a state of friction during the opera...

Problems solved by technology

[0005] However, the injection control of traditional wet rim lubrication usually uses the control method of fixed distance, fixed time and curve (inclination angle) to spray lubricating oil, which is prone to the problem of wrong injection, and cannot fully realize the precise positioning at the required line location. Injection, therefore, while a large amount of lubricating oil is consumed, the wear of the wheel flange is still relatively serious
