Centrifugal motor brake for pneumatic compactor
Vít, Jakub ; Kamarýt, Martin (referee) ; Škopán, Miroslav (advisor)
The aim of my thesis is the design of centrifugal brakes to prevent twisting of the combustion engine with pneumatic compactor. In the first part of my thesis I deal with existing and similar systems that prevent over speeding. In the second part I deal with the design of its own centrifugal brake. This includes basic functional, strength, thermal calculation, design of components and fabrication drawings according to the assignment.

Brakes and retarders of commercial vehicles
Kalnický, Jakub ; Zháňal, Lubor (referee) ; Fojtášek, Jan (advisor)
This bachelor's thesis is specialized search dealing with brakes of commercial vehicles. The work is divided into six main parts. The first part deals with genesis of brakes. The second part informs about fundamental terminology and definition of braking. The third part deals with distribution of braking systems by their purpose. Contents of fourth and fifth parts are friction brakes and retarders. The last part is dedicated to development trends of brakes.

Braking retarders for heavy commercial vehicles
Breckl, Lukáš ; Hejtmánek, Petr (referee) ; Fojtášek, Jan (advisor)
This thesis deals with the issue of retarders for trucks and buses. It concentrates on the fundamentals of their function and their construction. The thesis is divided into five main chapters. The first chapter describes braking power necessary to slow down the vehicle. The second chapter focuses on the main characteristics of retarders. The third chapter contains a description of their basic types. The fourth chapter compares these separate types. The concluding chapter of this thesis is dedicated to development trends. The thesis has a research character and does not contain new construction proposals.

Optimization Of Selected Proposed ČSN Elements For Road Design
Moravec, Karel ; Čepil, Jiří (referee) ; Radimský, Michal (advisor)
Subject of the work is comparison between the selected Czech standards elements for the road design and the standards in selected EU Member States. Based on the comparison and in agreement with the supervisor is designed to optimize the control elements of pitch towards sustainable transport safety. The work addresses the longitudinal gradients of motorways, expressways and other roads directionally divided according to standard ČSN 73 6101.

Design of control circuit for towing dynamometer
Rýznar, Jan ; Němec, Zdeněk (referee) ; Cejpek, Zdeněk (advisor)
This bachelor’s thesis is focused on design of a control circuit for a towing dynamometer. In the introductory part of the thesis is a detailed description of the towing dynamometer, including its main parts, which are necessary for proper operation. The next chapter is devoted to creating a dynamic model of an existing prototype using Simscape. Furthermore, based on the conditions from the dynamic model, a control circuit is designed, which is introduced in the form of a program into the control unit of the towing dynamometer. Based on the measured data from the transient responses, the function of the controller is gradually tuned to a satisfactory result. Finally, the function of the control circuit is evaluated and then measures to improve the stability, quality and accuracy of control are proposed.
