Five-cylinder diesel engine for commercial vehicles
Švarc, Marek ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this diploma thesis is the design of the configuration and the method of balancing the crank mechanism with the specified parameters. For a particular configuration, a crankshaft drawing is processed and a strength analysis, considering the crankshaft torsional vibrations is performed in Ansys FEM software. At the end of the thesis, an ideological design of the torsional vibration damper and its effect on the crankshaft stress in the Ansys FEM software is performed.

Study of vehicle torque vectoring
Hlaváč, Pavel ; Fojtášek, Jan (referee) ; Míša, Jiří (advisor)
This bachelor thesis deals with torque vectoring. This topic has become interesting in recent years, as there is a rapid development of electromobility. Torque vectoring system can be integrated into electric vehicles with ease because there can be two motors on one axle. In this thesis, various types of drives and drivetrains are described, differentials are also covered in detail. Vehicle dynamics is also described. After the vehicle dynamics, the very benefit of torque vectoring is discussed. Finally, sensors and programs that could be used to design and simulate the system are briefly mentioned.

Buggy Concept Design
Richter, Vojtěch ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
The aim of this bachelor thesis is to create instruction for the construction of a terrain buggy. It’s research of used technology, but there are also key components calculation included. The thesis is divided into five parts. In the first part, there is a research of the components of the racing vehicle and there are some equations for calculation of important parameters. Furthermore, there is layout and dimension of main components and the frame. In this part is also solved storage of the engine in the frame. The third part is devoted to the calculation of the necessary driving force of the vehicle and the parameters of the braking system. The following section discusses the concept of suspension and damping with respect with favourable kinematics of the system.

Driveline Design and Testing Methods
Poláček, Jan ; Straka, Tomáš (referee) ; Fojtášek, Jan (advisor)
This bachelor’s thesis deals with the methods of designing and testing of vehicle drivetrains. The first part of the thesis describes and explains the individual drivetrain components and their possible arrangements. Then, the test methods used in the development of vehicle drivetrains, which are increasingly demanded in terms of their efficiency and reliability, are explained. Therefore, this thesis summarizes the sophisticated simulation tools used in the design and development of vehicle drivetrains. In conclusion of thesis the importance of simulation and testing of drivetrain is considered.

Bike drivetrain
Daněk, Viktor ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This thesis focuses on the bicycle powertrain and its evolution. It describes the history of bicycles and gears. It provides an overview of the different gear train concepts. It includes an analysis of external drivetrains, hub gears, in-frame gears and other technologies used. It also focuses on the development of electric bicycles and electric drivetrains, including their classification by motor location on the bicycle and by the most common electric motor manufacturers. The thesis covers an analysis of gear shifting from a kinematic perspective and includes a computational simulation of the motion of a model of a shifter and its shift cable in Ansys software. The simulation brings useful insights for understanding the real operation of the shifter and the stresses on its gear cable when the chain is shifted between the pinions. The work also describes new or underused drive concepts and their characteristics. The different concepts are also evaluated in terms of their application to different types of wheels. The main result of the work is a complex description of the most used bicycle drive trains. The thesis also analyses the development of gear trains, electric drives and gear shifting.
