Computational Modelling of the Automotive Gearbox Dynamics Using Multi-Body Approach
Suchý, Pavel ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The thesis deals with construction of a computational model of the manual automotive gearbox MQ281 in MSC ADAMS View software, on which several static and dynamic operating states of the gearbox are simulated. The input for the MBS model construction is the CAD assembly of the gearbox in necessary detail and parameters of all gears. The computational model uses a custom model of bearings and the engagement helical spur gears based on the transmission error. The outputs of the simulations are courses of forces and moments acting in bearings, gears and synchronizing clutches, courses of shafts deflection, courses of angular velocities of shafts and gears, frequency analysis of operating states.

Development of transmission
Kocman, František ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis is focused on current trends of passenger car transmissions. The goal was to compile an overview of individual concepts with regards to the current trends. For each concept, there is a description of its construction and principle. The practical part is focused on the calculation of the basic parameters of a dual clutch transmission.

Motor Vehicles Manual Gearboxes
Skula, Libor ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis deals with motor vehicles manual gearboxes. A computational design of a gearbox is explained here, specifically gear ratios and their graduation. Then, basic types of gearboxes are described and functional parts synchromesh, gearshift and control mechanism are given in detail. Finally double-flow gearboxes and their types are characterized.

Conception of ATV (all-terrain vehicles)
Dosedla, Milan ; Vančura, Jan (referee) ; Porteš, Petr (advisor)
This thesis is review article of the current design and construction setup of ATVs. In the individual chapters are analyzed function of structural units and their advantages and disadvantages for the application. Much attention is paid to the design and construction of the brakes and axles. Work based on the analysis 30 models of ATVs from different manufacturers. This thesis reports the specifications of selected models. In conclusion we discuss the appropriateness of design solutions for different types of ATVs such as utility or sport models.

Převodová ústrojí osobních automobilů a jejich užitné vlastnosti
Vedral, Jan
In the thesis, I focused on the design of transmissions for automobiles and bring a comprehensive overview of their current status, ie., They mention which type of transmission system currently used in automobiles, what are their properties and how they control then in selected types of transmission mechanisms describe their functional characteristics and determine which types of transmission equipment is best suited for transmitting torque and power across the range of gradation gears, using specific engine to the wheels of a car. This comparison will be used diagrams that I created for the selected gear. In this work i focus on five-speed and six-speed gear units with manual transmission shifting, but also automatic gear unit and transmission transmission with powershift.
