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.

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.

Conceptual design of high performance glider with electric propulsion (in complience with EASA CS-22)
Hlůšek, Josef ; Sklenář, Filip (referee) ; Hlinka, Jiří (advisor)
This master's thesis is focused on conceptual design of glider with electric propulsion system following the CS-22 regulation. Statistical analysis of the glider with an auxiliary electric engine has been carried out in order to determine basic design parameters for conceptual design. Based on analytical drag polar, the flight performance parameters are calculated, in particular flight range and influence of the solar panels on the flight range. This thesis also includes preliminary design solution of accumulator placement within the wing.

Design of all-terrain vehicle
Brostíková, Amálie ; Karásek, David (referee) ; Rubínová, Dana (advisor)
This diploma thesis deals with design Quads. Specifically, a type of terrain utility quad, often referred to as the ATV. To drive the machine uses two electric motors. The ultimate designer's proposal responds to the significant social trends that support the economy and ecological design. These parameters together with the yield of the machines are non-traditional solutions to this type of field machinery.
