Hydraulic circle of undercarriage two-way vehicle
Rozumek, Jaroslav ; Tomeček, Pavel (referee) ; Škopán, Miroslav (advisor)
The aim of this diploma thesis is a concept of hydraulic (hydrostatic) circuit of rail – road vehicle drive for the drive on communication and railway. As my work is not related to a specific type of road vehicle dedicated to a drive on railway, my work is of strictly reference nature. On request I was provided by Bosh Rexroth s.r.o. with a hydraulic scheme of two-way undercarriage (see appendix), which is also a source material for the new concept. My work is focused on interests of SaZ s.r.o., which deals with the development and rebuilding of road vehicles into rail – road vehicles. The first phase is focused on the choice of the most convenient component of railway undercarriage in accord with the assignment. The second phase is oriented on the calculation of travel parameters, dimensioning of systems with concretization of typal mark of components. A part of the second phase is also a concept of hydraulic braking system of rail undercarriage. After that follows a complete evaluation, eventually an alternative solution of given problem.

Drive of control ring PVE Merkersbach
Skoupý, Jiří ; Veselý, Jindřich (referee) ; Kašpárek, Jaroslav (advisor)
This thesis is focused on determination of forces acting to regulation ring of water power plant Markersbach (Germany). Solution of the problem is realized for two variants of servomotors – with and without servomotors acting surfaces balancing. Next topics of this thesis are strenght calculation of piston rod and bottom of the servomotors. Minimalization of the size of servomotors plungers by change of regulation kinematics has been done and minimal pressure in the pressure tank is determined. At the conclusion of this thesis received results are mentioned and its interpretation has been done. This thesis is provided for company Litostroj Power, ČKD Blansko Engineering, a.s.
