Developments of Car Drive Train
Mičola, Ivo ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis deals with research themed developements of car drive train with a view to transmissions of race vehicles. The begining of the thesis is focused on clutch systems, final drive housings, differentials and universal shafts followed by discussion of transmissions, their basic categorization and describtion of individual types. The main part of thesis deals with sequentional transmissions.

Electromechanical drive systems in machine tools
Knobloch, Josef ; Synek, Miloš (referee) ; Blecha, Petr (advisor)
This bachelor thesis deals with a description of electromechanical drive system components. The electromechanical system construct is defined in the introduction part. Motors, transmissions, shaft coupling types in use as well as the ball screw types in use are individually described in the next part of the thesis. Manufacturer representatives on Czech market are stated for each of the parts. An example of electromechanical drive system calculation is included in the last part of the thesis.

Software for Optimalization of Gear Speed
Pokorný, Pavel ; Beran, Martin (referee) ; Svída, David (advisor)
Rolling vehicle is being influenced both by driver and many other factors of physical nature. These factors affect the whole behavior of the car, its performance, fuel consumption etc. It is very reasonable to cope with these factors then. The main aim during vehicle evolution (both civil and racing ones) is to optimize the influence of all invisible enemies as much as possible. The aim of this work is a description of factors influencing the moving vehicle. Several practical examples are included. The theory of transmissions is fundamental to the programme for creating a saw-diagram and gear speed optimization. Finally a few analysis of the real vehicles and subsequent evaluation will be done. The output of the work is an overview of factors affecting the moving vehicle, the results of performed analysis and programme for optimization of gear speed.

Modern Tractor Transmissions
Bartošová, Daniela ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This Bachelor thesis concerns an overview of the modern trends in the area of tractors transmissions. It explains the reason why both the power shifts and the continuously variable transmissions. Further on, this thesis emphasizes the innovative elements of transmission concept at selected tractor manufacturers.

USB Printer Switch
Mrník, Martin ; Frýza, Tomáš (referee) ; Hermany, Jiří (advisor)
This work deals with USB bus specification, its advantages, disadvantages, and different possibilities of use. Readers offers a closer look at the processes invisible to user during startup, operation and management of the device, their meaning, structure and timing. The work also discusses the possibility of connecting more computers to a USB device through switch and is dedicated to design of such a switch.

Change in the durability of concrete made of recycled concrete by alternative addition of ceramic admixtures
Stavař, Tomáš ; Hoffmann, Oldřich (referee) ; Stehlík, Michal (advisor)
The master thesis dealing with problematic about durability of concrete, with use of recycled concrete and addition of silica additions. Predominant for resistance of concrete constructions is surface layer, through which aggressive gasses and liquids penetrate from surrounding environment. The most important indicator of concrete durability is ability of surface layer transmissions of aggressive substants. In experimental part will be defined the actual state of surface layer by normal testing methods. The transmissions of surface layer will be tested on concrete cubes. Tests for transmissions of air (method TORRENT), of water (method ISAT), of acid gases (dept of carbonation by quick test in 98% CO2) will be carried out and also strength tests. Assessment of positive or negative influence of additions and amount of cement on durability and mechanical properties of concrete will be discussed in conclusion.

Effect of engine load on the output parameters of the tractor kits
Paulmichl, Roman ; Svída, David (referee) ; Bauer, František (advisor)
The thesis deals with the current situation in the construction of tractors, particularly engines and accessories. The work includes a methodology for measuring tractor rigs in traffic as well as methodology for plough/plow kits measuring. The measured values were tabulated, graphically presented and analysed. The thesis provides an overview of the issue of the combustion engine load placed on the engine by working conditions in transport, during primary soil tillage with different modes of operation of the tractor set. The thesis aim is to find out the practical effect of the engine load on the monitored parameters and to indicate possibilities for achieving higher efficiency in tractor units with minimum fuel performance
