Návrh pomocného hydraulického obvodu důlní lokomotivy

Abstract

The topic of the bachelor thesis is the design of an additional hydraulic circuit for the mining locomotive. The theoretical part focuses on a literature review on hydrogenerators for frequency-controlled drives, discussing the elements and systems of frequency-controlled drives. Components for frequency-controlled drives and their control by specific systems are analyzed. The practical part further deals with the calculation of parameters of orbit hydraulic motors under specific working conditions. Another section includes the design of the hydraulic circuit itself and the specification of components forming this circuit, which will be used for braking and providing traction to the locomotive wheels. The entire description and operation of the circuit are addressed in the concluding part of the practical section.
