Technical field

The present embodiments relate to Transit Equipment lubrication technical field more particularly to a kind of train wheel rim solid lubrications Control system.

Background technique

In modern railway transportation transport field, wheel-rail friction and lubrication are related to traffic safety, haulage capacity consumption, wheel The problems such as the abrasion of rail material and maintenance cost, therefore the great attention by each rail traffic relevant enterprise department.In order to Rail traffic high speed, heavy duty, the needs transported safely are preferably adapted to, wheel-rail lubricating mode is each relevant industries researcher's Development is continuously updated under joint efforts.Early in carrying out rail lubrication on track circuit in the 1960s, beginning to appear in Measure, lubricating oil on curve foreign stock rail is coated by hand by trackwalker.Although oiling quality is not satisfactory, to extension steel Rail and wheel still play the role of sizable service life.The wheel-rail lubricating mode master method to be used in China is to adopt Take HB type or HLP type series rim lubricating device.However, either HB type or HLP type rim lubricating device is oil liquid formula Lubrication reduces the abrasion between wheel track by forming oil film in the oil spout of wheel rim root.This method is born high in wheel rim root When load and high temperature, liquid oil film can be destroyed, to lose lubricating ability.In addition, often being sprayed in practice The problems such as oil nozzle plug, Injection Control box failure, flange lubricator not oil spout is caused, or grease is sprayed on wheel tread, Decline wheel rail adhesion coefficient, there is lead to problems such as train wheel dally and the pollution of EEF bogie and route.

To solve the above-mentioned problems, it is thus proposed that the scheme of wheel flange lubricating, but current city are carried out using solid lubrication block It is maximum value that field, which takes the prepared control system of this scheme not account for train coefficient of frictional resistance in curve location, (need to control at this time carry out emphasis lubrication), coefficient of friction is smaller when train linear running (does not need control at this time and carries out emphasis Lubrication) the characteristics of, but be lubricated always on a train line, unnecessary waste of material can be lost in this way.
