Design Solutions of Recent Road Motorcycles above 500ccm
Vaculík, František ; Beran, Martin (referee) ; Ramík, Pavel (advisor)
Subject of this project is current knowledge summary in construction of road motorcycles with displacement above 500 ccm. Project is divided to particular construction units as an engine, transmission system, frame and wheels suspension, brake system, electrical equipment and other components. In each unit is an analyse of possible technical solutions, their advantages, disadvantages and materials used in production. In the conclusion of the project is comparison of three different motorcycles manufacturers and their technical solutions.

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.

The utilization of the individual gears for tractors higher power series
DRAHOŠ, Pavel
The aim of the bachelor thesis was to monitor the operation of two tractors with different transmission variants with a shift under full load and the group lifting under load, in terms of used gear at different working deployment (stubble, plowing, sowing). First, the literature review describes the historical development, construction and activity currently used tractor transmissions. The following is a description of the methodology of measurement and evaluation, bringing used calculation formula. Custom measurements were performed on tractors John Deere 7810 with transmission Powershift 19/7 and AutoQuad 20/20 and proved that in practise there are only using a few of the many gears installed. For a simple design optimization gears are used total tables extended with graphs for individual transmissions. Based on the measurement and after the data analysis is presented the proposal of transmission with 10 forward gears and 2 reverse gears with a fully stamped gears under load. Current manufactures and the market, however, now offer tractors with mechanical transmissions increasing amount of gears than in the past. Increasingly, the trend is promoting the installation of transmisson with the fluent change of transmission ratio to the current use of advanced contemporary electronic transmission control and engine tractor.
