Sport downhill cart for the disabled
Šantavý, Ivo ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor´s thesis deals with the development of a "Sport downhill cart for the disabled" prototype. This project was jointly inspired by Human Power Vehicles and by components from various industry sectors. After a description of the above mentioned vehicles, the work describes the successive development of the cart, including construction solution, and a component and frame modeling in the CAD system Autodesk Inventor. The total calculation of the entire "Sport downhill cart for the disabled" is presented in the conclusion.

Electric drives in commercial vehicles and buses
Bahenský, Štěpán ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor thesis focuses on electric and hybrid powertrains, which are used in utility vehicles and buses. According to this bachelor thesis is divided into two main parts. The first part deals with pure electric drives and its basic components. The subchapters describe various types of engines that are commonly used, but also the features and technologies of batteries. The second part deals with hybrid technologies, division according to the arrangement of components in vehicles, advantages and disadvantages of these solutions. Attention is also paid to the possibilities of battery systems. At the end of both parts, there are examples of commercial vehicles and buses with appropriate motorization, their comparison with competing models and a list of chosen technical parameters. The final chapter summarizes the current direction of the market and its further possible development in the future.

Car Front Axle Driveline Gearbox
Černuško, Lukáš ; Černý, Jiří (referee) ; Kaplan, Zdeněk (advisor)
Goal of the Master Thesis was to design conception of electric vehicle driveline, which is able of torque vectoring between each wheel independently and to design front axle gearbox. The aim was to use up the car on race track and to test dynamic properties of electric vehicle for follow-up development. Due to determined requirements and possible solutions the conception of driveline was designed and basic parameters were defined. The main part of the thesis contains a design of gearbox including strength calculation of gearing, the control of shafts to fatigue and elasticity limiting states, life of selected bearings. Gearbox case was subjected to FEM analysis. The last chapter uses simulation to gain vehicle acceleration. Designed electric driveline is applicable to other sport vehicles after some modifications.

Hydrogen and automobiles
Břoušek, Lukáš ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The purpose of this thesis is to demonstrate the possibilities of hydrogen-based gear in personal cars. The thesis also describes the hydrogen from the perspective of the characteristics, the form of production, conserving, distributing and its utilization. Furthermore, in more details are described and compared currently well-known hydrogen-based devices, for this purpose the complex analysis Well to Wheel will be used. Final part of this publication will be devoted to evaluation of this analysis and also the thesis will outline what are the probable trends of the hydrogen-based technologies.
