Design of transmission mechanism for Formula Student Dragon 7
Fanta, Tomáš ; Janoušek, Michal (referee) ; Svída, David (advisor)
This thesis examines the various types of transmissions which allow to seamlessly change gears without interrupting the transfer of a motor's power output. In particular, it elaborates on the advantages and disadvantages each design presents for a FormulaStudent/SAE vehicle. Furthermore, the thesis explores the selection of gear ratios and simulates acceleration parameters in order to achieve the best possible dynamic behavior. What is more, the thesis presents a concrete implementation of a transmission for the Husqvarna FE 501 motorcycle redesigned with the Zeroshift mechanism. It includes a fundamental change in the operation of the clutch as well as a gear stress analysis. Last but not least, the TU Brno Racing team incorporated the main conclusions of the thesis into the team's vehicle in order to improve the team's standings in international races.

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.

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

Hodnocení technických parametrů převodových ústrojí motorových vozidel
Tušer, Milan
The Bachelor thesis focuses on the current state of tractor transmission systems. The first term described is transmission gear. In another part, the tractor gears are divided. The following section is devoted to describing the remaining parts of the transmission system, which are clutches, distribution boxes, differentials. The last theoretical part is devoted to the synchronisation of gears and gear oils. The sections are described and supplemented with graphic images. The work also includes an analysis of the technical parameters of two selected gearboxes and an evaluation from several points of view.

Vliv konstrukce převodovky na ztráty u osobních automobilů
Rozlivka, Jakub
This diploma thesis deals with the influence of gearbox design on passive losses of passenger cars. First chapters are focused on theory of construction of transmission and determination of vehicle resistance opposing its movement. Experimental work concerns measurement on chassis dynamometer and brings comparison of obtained values. The last chapter analyzes financial issues of different design of gearboxes installed in identical cars.
