Szkudlarek Z., Janas S.

Mechanik

2015

R. 88, nr 8-9

692--694

Przedstawiono innowacyjną konstrukcję napędu, opracowaną w Instytucie Techniki Górniczej KOMAG, w której zintegrowano przekładnię mechaniczną z kołem napędowym. Scharakteryzowano obecnie stosowane rozwiązania oraz innowacyjność proponowanej koncepcji pozwalającej lepiej wykorzystać parę cierną koło–szyna. Omówiono konstrukcję 3D zespołu napędowego oraz wstępne wyniki analizy numerycznej jego korpusu.

Presented is an innovative solution of the drive system as developed in KOMAG Institute of Mining Technology, which consists in mechanical transmission gear integrated with the drive wheel. Current solutions are described to expose innovativeness of the new concept, which should provide for more efficient use of the wheel/rail frictional pair. Discussed is the 3D model of the drive system and preliminary results of numerical analysis of its case body are presented.

Frictional couplings of wheel with a rail in a brake control system of rail vehicles

Purpose: Discussion on use of frictional coupling of wheel with a rail for detection of surface condition of track ways in coal mine undergrounds is the paper objective. Design/methodology/approach: The method for detection of surface condition of track ways is based on using of dedicated converter installed on the locomotive chassis with active part in a form of “tracking wheel” that moves on the rail surface together with the locomotive. The converter is equipped with a system for torque load and a sensor measuring its rotational speed. Change of track surface is determined by momentary changes in rotational speed of “tracking wheel” due to its slippage. Findings: The described method for detection of track ways surface condition enables to generate information signal which transferred to master braking control system of the locomotive eliminates excessive slippage during braking. Research limitations/implications: The presented results confirm rightness of accepted method for detection of track ways surface condition indicating for necessity of modification of developed test rig to get repeatable information about current track surface. Originality/value: The method for detection of track ways surface condition is the novelty approach to braking of rail locomotives used in the mining industry. It is also an alternative option to the present solutions based on known ABS (Anti-Lock Braking System) system used in automotive industry.
