Proposal of driveline of prototype for Shell Eco-marathon
Skácelík, Radek ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
In the bachelor thesis, the drivetrain design of the racing car is solved and described. The competition rules are summarized in the introduction. Then the driving resistances and drivetrain design variants are evaluated, which main objective is to achieve low fuel consumption. The solution is focused on the concept of a planetary gear-shifting hub, in combination with the synchronous belt drive. The Honda GX25 engine with a centrifugal clutch and the driven wheel dimension of 20” is used to drive the design. The design solution is shown at the assembly drawing.

The Present State and Development Trends of Passenger Cars Gearbox Design.
Chuchma, Ondřej ; Rasch, František (referee) ; Blaťák, Ondřej (advisor)
The bachelor thesis includes complex information about nowdays gearbox, which are used for automobile. In general it describes constructional ordering and principles of function of gearbox. The next part provides the information about individual kinds of gearbox and compares their properties and parameter. The most extensive part is engaged in dual clutch gearbox as the most developing kind of transmission of automobile. In the end author deals with the most probable future development in branch of gearbox for segment of automobile.

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.
