Problems solved by technology

If the lubricating oil is insufficient, it will not be able to play its due role. If the lubricating oil is too much, it will accumulate and be squeezed onto the rail surface, which will easily cause the wheels of the locomotive to spin

Embodiment 1

[0053] In this embodiment, the priorities of the three control modes are test mode, manual mode, and automatic mode in sequence. Through reasonable setting of priorities, smooth switching of the three control modes is ensured without affecting the normal use of the rim lubrication system.

[0054] Such as figure 2 As shown, the control method of the automatic mode is:

[0055] S11: TCMS judges that the current train speed is higher than the rim lubrication low speed limit V (generally V=5km / h), and there is no request to close the automatic mode, WFL manual request or WFL test request, then execute step S12, otherwise reset the timer 2;

[0056] S12: After the timer 1 counts, if the sand spreading system is activated, then reset the timer 1, otherwise execute step S13; wherein, since the sand spreading system is used to realize sand spreading between the tram wheel and the track, increase two The adhesion between the two, and the rim lubrication system is to reduce the adhe...

Abstract

The invention discloses a method for controlling a rim lubrication system of a tramcar, which adopts a train control and management system (TCMS) to control a rim lubrication system (WFL) and is provided with three control modes including an automatic mode, a manual mode and a test mode. The train control and management system TCMS is connected with a human-computer interaction module HMI, and anoperation interface of a wheel flange lubrication system WFL is arranged on the human-computer interaction module HMI and used for inputting a corresponding instruction for controlling the wheel flange lubrication system WFL. The train control and management system TCMS selects a control method for executing an automatic mode, a manual mode or a test mode according to the detected train speed andan input corresponding instruction so as to correspondingly control the wheel flange lubrication system WFL. Three control modes are set for the rim lubrication system, reasonable control over the rimlubrication system can be achieved, excessive lubrication in a local rail area is avoided, and the lubrication efficiency and reliability of the rim lubrication system are improved.

Description

technical field [0001] The invention relates to a control method for a lubricating system of a wheel rim of a tram, and belongs to the technical field of a lubricating system for a wheel rim of a rail transit vehicle. Background technique [0002] When the train runs to a small curve section, severe friction and wear will occur between the wheel rim and the rail gauge angle. This wheel rim wear and rail side wear are one of the main damage types of the wheel and rail on the curve. It will increase the running resistance of the train and bring about problems such as noise pollution. [0003] The flange lubrication technology is an important means to slow down the wear of the flange rail side. Properly lubricating the wheel flange and gauge angle can improve the contact state of the wheel and rail, not only prolong the service life of the wheel and rail, but also reduce the derailment coefficient, benefit driving safety, reduce wheel-rail noise and have a certain energy-savin...
