Engines for Le Mans Series
Herman, Pavel ; Blaťák, Ondřej (referee) ; Svída, David (advisor)
This bachelor´s thesis deals with the overview of development the drive units, which are used by racing cars of Le Mans endurance series, mainly the race 24 hours of Le Mans. In the first part is outlined the general characteristic the series and the race 24 hours of Le Mans itself. There are briefly described the instructions and the most important technological limitations, observed by designers. The second part contains an owerview of racing cars engines, which are interesting from the historical point of view either by their construction or by achieved success. The last part is devoted to the constructional comparison of drive units of present participants the Le Mans series, their description and the important technical specifications.

Travelling Crab
Šponar, Pavel ; Kašpárek, Jaroslav (referee) ; Malášek, Jiří (advisor)
Bachelor thesis deals with a project of the travelling mechanism of the travelling crab (electric motor and gear-box) and check calculation for starting. The aim of this work is to design a travelling wheel with save, therefore it is necessary to design the suitable normalized components. The solidity calculations of the travelling wheel, the bearing and shaft ( static and dynamin straining).

Gravital conveyor for transport
Fatka, Milan ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The aim was to propose a conveying gravity path for the transport of steel casting in the context of inter-transfer service. The conveyor is dealt with valid norms with regard to simplicity of design, production and assembly (disassembly) with broad use of standardized parts. It was also seen to be done to take advantage of the proposal in solution of similar specification.

Control Systems of Gears Changing on Load in Tractors Gearboxes
Holub, Přemysl ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is interested in the overview of tractor’s gearboxes, which are changing on load. There are reasons, why it has to be costructed and there are requirements for it. There are also described PowerShifts, which allow us gear changing on load. After basic description of concrete gearbox, there is always some example of using in current tractors. In period named Mechanical gearboxes, wchich are changing partly on load there is more space for Zetor tractors and its gearboxes. In one of the last period there is important part about continuously variable transmissions where the driving speed is regulated steplessly. These gearboxes are considered to be modern technology of transfer engine torque.
