Solution technology of manufacturing for part "disc of coupler"
Borek, Vít ; Osička, Karel (referee) ; Mouralová, Kateřina (advisor)
An introduction to main principles of coupling and description of basic types has been done. An analysis of the given component and a proposal for suitable intermediate was made. A selection of machines and tools for individual operations has been done. A proposition of technologic process and enumeration of machines times was proposed. Economic evaluation containing costs for tools, cooperation, workmen’s wages, intermediate and energy for operating machines has been calculated.

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.

Optimization of the existing construction of magnetorheological clutch
Bedřich, Miroslav ; Růžička, Bronislav (referee) ; Roupec, Jakub (advisor)
This work deals with the reconstruction of magnetorheological (MR) clutch. The extensive research on the use of magnetorheological technology in practice was developed in the first part. The function of MR dampers, MR brakes and MR clutches were described. Some parameters of MR clutches were listed and compared. The second part concentrates on construction modifications to improve some parameters of MR clutch. The experiments verifying improvement of operating parameters of MR clutch were carried out in the third part.

Stroke mechanism of crane trolley
Galas, Radovan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
Bachelor's thesis deals with design of stroke mechanism of crane trolley loads for the weights which do not exceed 5 000 kg. This thesis divided into written and practical sections. Written part deals with the calculation of the principal dimensions of lifting and stress control of cable reel. In this work there are also given reasons for choosing certain key parts of the lifting mechanism, such as: electric motor, gearbox, etc. Prior to the calculations in each chapter there is usually located a short introduction of the topic. The practical part contains a drawing of the complete lifting mechanism, cable reel assembly and two production drawings.

Conception of ATV (all-terrain vehicles)
Dosedla, Milan ; Vančura, Jan (referee) ; Porteš, Petr (advisor)
This thesis is review article of the current design and construction setup of ATVs. In the individual chapters are analyzed function of structural units and their advantages and disadvantages for the application. Much attention is paid to the design and construction of the brakes and axles. Work based on the analysis 30 models of ATVs from different manufacturers. This thesis reports the specifications of selected models. In conclusion we discuss the appropriateness of design solutions for different types of ATVs such as utility or sport models.

Passenger Cars Four Wheel Drive.
Hrádek, Zbyněk ; Rasch, František (referee) ; Blaťák, Ondřej (advisor)
The aim of my Bachelor´s project is to form the search describing individual drive concepts of the all cars´ wheels. It is focused especially on the construction, working principle and usability of the particular concepts. The beginning of the thesis is interested in the the history as well as the advantages and disadvantages of this engineering solution. In the following part the most used drive concepts are described. The end of the project covers the summary of the acquired information and the consideration of how the all wheels´ drive will be developed in the following years.
