Car differentials
Sedláček, Petr ; Ramík, Pavel (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis deals with differentials with emphasis on self-locking differentials. The first part deals with the transmission system, followed by a part introducing the issue of differentials, their distribution and description of individual structures. At the end of the work we find the solutions of self-locking differentials with focus on Torsen type differentials. The aim of the work was to create a comprehensive overview of differential issues.
Topics of the first and last mile in urban transport
Večerka, Marek ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the issue of the first and last mile in urban transport. It generally defines the issues of the first and last mile and provides an overview of available solutions. At the same time, it briefly looks at the future in the form of autonomous management. The individual solutions are described and subsequently related to the continent of Europe. The next step is to map and analyse the available options in the Statutory City of Brno. The result of this work is an evaluation of current available solutions and a proposal for further solving the problem of the first and last mile.
Car gearboxes
Charvát, Adam ; Ramík, Pavel (referee) ; Kaplan, Zdeněk (advisor)
This bachelor's thesis is focused on the most common transmission types of passenger cars and their components with a focus on manual transmissions, automatic transmissions, dualclutch transmissions, continuously variable transmissions, and transmissions for electric and hybrid vehicles. The work deals with the construction, principle of operation and comparison of the properties of these devices. Thesis also contains a look at development trends of these transmissions.
Car differentials
Čapek, Štěpán ; Ramík, Pavel (referee) ; Kaplan, Zdeněk (advisor)
Technical solutions of car differentials. Description of the vehicle transmission system and types of differentials with their evaluation. Following active systems and active differentials with explanation of their function and summary of advantages and disadvantages of their application and use by individual car manufacturers.
Supercharging of spark ignition engines
Májek, Ondřej ; Ramík, Pavel (referee) ; Kaplan, Zdeněk (advisor)
The work presents basic terms, options and construction solutions of turbocharged petrol engines. This work also contains positives and negatives of each construction solution and my evaluation.
Stirling cycle
Veselý, Milan ; Ramík, Pavel (referee) ; Kaplan, Zdeněk (advisor)
This work was aimed to comparise of ideal traditional and alternative termodynamic cycles, calculations and determinativ of efficiency of these cycles, executions of p-V and T-S diagrams with a closer look at the Stirling cycle.
Axle design for autonomous electric minibus
Müller, Viktor ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
This thesis deals with an axle design for an autonomous minibus. The theoretical part is about axles then the next one goes over the given parameters. Following with a selection of suitable parts for use and designs of parts for production. This chapter is also about geometry and driving characteristics analyzation. The next chapters are devoted to the calculations of the loads on the lower arm, its design and static analysis. The last chapter combines all the parts together into a conceptual design.
Four Cylinder and Six Cylinder Engines for Agricultural Tractors
Potůček, Šimon ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis summarizes actual technologies and trends by tractor engines and mention product portfolio of the most important tractor engine’s manufacturers used in the Czech Republic.
Design of Driveline Placement System Units in Special Purpose Vehicle
Neuman, Ondřej ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This thesis is concerned with designing a powertrain mounting solution for high mobility off-road vehicle. It is created in collaboration with company Advanced Design Solution spol. s.r.o. The focus is to present a design process of a specific frame structure that supports the powertrain and isolates its vibrations. Majority of the thesis describes the use of finite element methods to assess static and cyclic loading of a welded structure. It also refers about selecting the correct vibration dumpers and covers manufacturing of the part.
Measuring the power of IC-engines
Adamec, Vojtěch ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with topic measuring the power and the torque of internal combustion engines on chassis dynamometer. The aim of the thesis was to show advantages and disadvantages of different types of dynamometers, to make review of standards for measuring power on chassis dynamometer, effect of atmospheric conditions, resistances and slippage. Thesis also describes evolution, different designs of chassis dynamometers, effect of roller diameter to rolling resistance and deformation of tire, suitable types of dynamometers for chassis dynamometer, equipment of testing room, modes of operating and differences between static and dynamic power testing. In the end I have made prediction of incoming development devices of this type with regard to evolution of intelligent chassis control systems and electric vehicles.
