Structure and Use of the Measuring System for Research of Lubrication Device
Brhlík, Rostislav ; Omasta, Milan (referee) ; Nevrlý, Josef (advisor)
This work deals with an adaptation of the measuring system for the functional analysis of the lubricant divider. Within the new structural design, there were used manometers, flowmeters and dynamic scales to determine the properties of the lubrication system; data acquisition card and the appropriate software were designed too. The methodology of data measuring and analysis were also elaborated. The methodology is based on the experience from measuring, which was realized with the lubrication system OK - 02 from Tribotec Company. Finally, the cascade lubricant dividing system was designed. This is a newly designed flow divider with an innovative internal layout. The aim of the proposed measurement system is an optimization that will lead to effective dividing of lubricating mixture and applying the necessary amount of lubricant to wheel flange.

Design of Wheel Flange Lubrication Experimental Apparatus
Nepovím, Radovan ; Dzimko, Marián (referee) ; Hartl, Martin (advisor)
The diploma thesis deals with construction design and practical realisation of experimental apparatus for investigation of wheel flange track vehicle lubrication. Experimental apparatus in full-scale uses optical interferometry for investigation of lubrication behaviour in wheel flange contact. It is an innovative approach which has not been used for such experiments so far. The aim of the following measurement with this apparatus is to determine the minimal amount of ecological lubrication in wheel flange contact under certain conditions when there is no lubrication film interruption. The apparatus enables to measure real rail wear. This work contains the apparatus description for the study of wheel flange lubrication, wheel flange contact specifications, the description of its influence on wear and acoustic emission, and a detailed description of the experimental apparatus.

Experimental Study of Wheel Flange Lubrication
Frýza, Josef ; Dzimko, Marián (referee) ; Omasta, Milan (advisor)
This diploma thesis deals with the experimental study of the influence of operating conditions on the tribological aspects of the wheel flange and rail gauge contact. The wheel flange contact occurs when the vehicle moves on a curve track and it leads to severe up to catastrophic wear regime. For effective reduction of wear is important to apply a suitable amount of lubricant at appropriate intervals into the contact. The issue in this work comprehensively studies using of three laboratory apparatus and six methods that are theoretically and experimentally compared. Assessed are friction, wear, distribution and film thickness of lubricants for different contact conditions. The resulted amount of lubricant and interval of its application eliminates development of seizure at low consumption of lubricant. The understanding of mechanisms that occur in the wheel-rail contact not only helps to reduce operating costs and improved to energy efficiency of movement of vehicle on a track, but it is the basis for safe, reliable and ecological operation of rail transport.
