Design of Vehicle Sequential Gearbox
Šardický, Jakub ; Smolka, Josef (referee) ; Hejtmánek, Petr (advisor)
The thesis deals with the search of the current sequential gearboxes and the structural shift of the Škoda Felicia 1.6 MPI synchronous transmission to the manual sequential gearbox. Based on the assignment, the schematic reconstruction principle is included. This principle i s then elaborated into a detailed design and the thesis focuses on strength analysis of newly created parts of reconstruction, optimization of these parts and control of their fatigue life. The thesis ends with the theoretical continuation of mechanical conversion to a fully electronic sequential gearbox.

Assembling the Technological Process for a Part of the Gearbox
Hoffmann, Jiří ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The aim of my bachelor´s thesis is to create a technological process for manufacturing a gear housing component.. The chief output of my work is developing a technological process with the selection of appropriate tools for machining the casting. The thesis also deals with generating NC program, techno - economic comparisons, the design of worholding devices and recommends solutions of other identified issues.

Continual helicoidal mixer
Pelka, Tomáš ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma project works out and is focused on the continual mixing process of the particular matters. The project is divided into following chapters. Chapter 1 includes mixing theory and information of the experimental work of the particular matters for blade using. In chapter 2 there is Evaluation and calculation of the technical parameters for the mixer. Chapter 3 deals with the engine proposal and chapter 4 includes calculation and design work of the gear transmission. Chapter 5 includes the stress analysis of the shaft and blade with the I-deas software. In attachment there are also the mixer arrangement drawing and detailed drawings of the key parts and groups for the mixer.

Modernizing of Dynamometer for Passenger Vehicle
Meduna, Martin ; Blaťák, Ondřej (referee) ; Svída, David (advisor)
The basic aim of this thesis is to design optimisation of the brake bench in question. For this kind of optimisation, it was necessary to ascertain which failings the current brake bench exhibited. After ascertaining such failings, design of modification to this brake bench must be performed. In terms of this thesis, it was ascertained that the brake bench has insufficient brake power. Based on this finding, two alternatives for modifications have been selected. The first is replacement of the dynamometer and the second is insertion of a gear box into the brake bench. Rigidity analysis was performed on the gear casing.

Comfort and Safety
Zuber, Zalán ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
The purpose of my thesis was to present the system of safety vehicles new solution and to value their role. My thesis summarize the most important results from this sector, presents the system of the control in the vehicles and the colonies of vehicles in different levels, used senzors and anomalies. Next to the technical problems it mentions the problem with law and moral problems. Fully deals with Predictive Safety Systems.

Crane Stroke Mechanism
Vydra, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of crane stroke mechanism with lifting capacity of 12 500 kg. At the beginning is research of different design solutions, their comparison and finally selection of the most suitable conception. Before calculation part of each unit is short theoretical part, which brings basic information about issue, whose result in choice of product from catalogues. On the grounds of calculations, firstly hoist parts are chosen, such as rope, pulleys, rope drum and main units of crane mechanism – electric motor, gear box and brake with coupling. Final part deals with strength calculations of rope drum and drum shaft and design of his bearing housing. The practical part of the work are assembly drawings of crane stroke mechanism and rope drum weldment.
