Gearbox with Gears Changing on Load
Formánek, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor work is focused on analysis of structural arrangements, technical and operating parameters of a gearbox with gear changing on the load. First part of this work is devoted to gears distribution, their gear change and the ways of gear change. The following part describes various structures of gearboxes, their principle and control. The summary evaluates advantages and disadvantages of the gearboxes and describes estimation of following development in this field.
Crankshaft mechanism of Stirling engine
Valčík, Martin ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This diploma thesis is focused on the design of the driving mechanism of Stirling engine, where was chosen modification of these engines with rhombic drive. Subsequently is constructed kinematical, dynamical and thermomechanical mathematical model. Finally, is going from these models for execution strength control and drawing documentation.
Hybrid vehicle propulsion
Sommer, Matěj ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This thesis sums up a comprehensive overview of all possible ways of hybrid propulsion and points out the andvatages and disadvantages of each of these designs with special attention to fuel cell vehicles. It includes a presentation of my own opinions regarding this issue and an estimation of future development of hybrid propulsion technologies and their place on the market with personal vehicles.
Ideal cycles of combustion engines
Kertész, Tibor ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The main subject of this bachelor´s thesis is to summarize basic theoretical knowledge of ideal thermodynamic cycles and to develop their mathematical models in Matlab to calculate and draw diagrams of each cycle. Based on the calculated values, it was possible to compare the cycles with each other.
Transmission of HPV
Martinát, Antonín ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This diploma thesis concerns the design proposal for a bicycle gearbox powered by human force. The first part summarizes the existing solutions. The second part includes the proposal of the new design, together with the calculation of the strength for selected parts. Attached are the drawings documenting the findings.
Renewal energy in HPV
Bittner, Ivo ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This thesis deals with comprehensive study and design of recovery system of a road vehicle powered by human power. It contains an overview of different types of heat recovery devices, their characteristics, advantages, disadvantages and applicability in the construction of such a vehicle.
Personal car differentals
Csémi, András ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor’s thesis deals with the topic of car differentials with special attention to self-locking differentials. The first part is dedicated to the description of the powertrain. Then the main part is about the differentials, their division, the description of the constructions and the principle of function, with a focus on self-locking types. The aim of the thesis was to create a summary of self-locking differentials.
Řehánek, Matěj ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This diploma thesis is focused on design proposal of bicycle frame, which is powered by human force and then strength analysis of designed frame. Vehicle is designed to city and relates to physically handicapped persons and elderly people. This thesis content comparison of different types of bicycles.
Human Powered Vehicle Differential
Andrlík, Ladislav ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The aim of this diploma thesis is the design of the differential of a road vehicle driven by a human force, intended for daily driving in the city with a focus on older users. The vehicle for which the differential is designed is strictly a pedal tricycle. The introduction of this thesis briefly outlines the history of pedal tricycles. The second chapter explains some technical terms relating to tricycles and bicycles in general. Further chapters of the research part describe the current structures of tricycles, the principle of a differential function in motor vehicles and design possibilities of the differential for pedal tricycles. The practical part of my work includes the design of a differential for pedal tricycle, the strength analysis of selected parts of the differential, drawings of the differential assembly, production drawings of selected parts and proposal of the torque transfer from pedals to the differential.
Testing of piston combustion engines
Humpolíček, František ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The aim of this thesis is to compile knowledge and provide a comprehensive overview of the testing of piston combustion engines, dynamometers and types of testing for engines designed for agricultural machinery. Types of various tests are described, dynamometers are categorized and the characteristics of individual components are studied. Different types of tests are also categorized and their principles summarized. Based upon these findings, the most suitable configurations are determined for a borrowed dynamometer to measure agricultural machinery. The borrowed dynamometer was used to conduct practical measurements of the external speed characteristics of combustion engines in agricultural machinery. It was experimentally determined that the duration of measurement is limited by the reduced efficiency of eddy current brakes due to increasing rotor temperature.
