Race Cars Electric Drive
Nosek, Václav ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This bachelor thesis deals with the categories of motorsport vehicles powered by electric drive. In the theoretical part, a brief history of electric drive and the classification of the different types of electric vehicles are first mentioned. The main part then discusses the main categories of electric motorsport and several models, focusing on their technical specifications. The practical part of the thesis focuses on the comparison of concepts in the T1 racing category. The main emphasis here is on verifying the currently achievable capabilities of electric drive compared to other methods used in the racing environment of the category.

Design of plasma cutting machine
Vejrosta, Pavel ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
This bachelor´s thesis is focused on the design of plasma cutting machine. The work begins with an introduction to plasma itself, covering the theory related to topics important for understanding the issues of plasma cutting and the operation of plasma cutting machines. This section is followed by review and market research in field of plasma cutting machines. Furthermore, the thesis establishes specific requirements and characteristics that are necessary for the actual design of the machine. The next section proposes various solution concepts and selects the optimal variants of the main parts of the machine, including supporting structure, type of drive, linear guides, electric drive, plasma torch, power source, safety and other elements. The selected parts are verified using design calculations. The actual design of the machine and the drawing documentation are created in Solidworks 2023. The conclusion of the thesis presents the final design, proposes possible improvements, compares the results with the set goals, and gives a final evaluation of the designed plasma cutting machine.

Planetary Gearboxes in Passenger Cars Construction
Timko, Richard ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The bachelor's thesis focuses on the research collection of planetary transmissions used in passenger cars, based on their conceptual arrangement and drive type. A simple planetary gear set and the Ravigneaux with the Simpson compound planetary gear trains are kinematically described, aiming to establish their basic kinematic equations. Subsequently, specific examples of planetary gearboxes are selected and described for internal combustion engine, electric, and hybrid drives. Additionally, a complete kinematic and force analysis of the ZF 8HP automatic transmission is conducted.

Urban three-wheeled vehicle with electric drive
Černík, Adam ; Porteš, Petr (referee) ; Tobiáš, Martin (advisor)
This bachelor thesis deals with the conceptual design of the chassis of a three-wheeled. The total payload od the vehicle is 160 kg. At the beginning, the work deals with the search for different types of chassis in used three-wheeled vehicles. The advantages and disadvantages of various chassis concepts and the subsequent choice of one them are also summarized. Then the conceptual parameters of the vehicle are selected. At the end a 3D model is modelled in program Inventor, which corresponds to the selected conceptual parameters. This model is used to visualize the designed chassis of three-wheeled vehicle.
