Planetary Gearboxes in Both Passenger Cars and Trucks Construction
Novák, Petr ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The thesis deals with the use of planetary gears in automatic transmissions for cars and trucks. The transmission part consists of Simpson and Ravigneaux gears. Therefore, their kinematic analysis is performed here. A complete description of the automatic gearbox explains in detail the principle of the function of the gearbox as a whole. Furthermore, the work is divided into two parts - gearboxes for cars and trucks. A research is carried out, the main characteristics of the group are described and their representative is discussed in detail. In the last part the kinematic and force analysis of ZF - Ecomat 6HP 602 gearbox is carried out.

Innovation of built-up crankshaft for minibike engines
Doležal, Lukáš ; Mazůrek, Ivan (referee) ; Hanuš, Stanislav (advisor)
The present diploma thesis deals with innovation of built-up crankshaft of Blata minibikes. Minibike is the type of a small two-stroke motorcycle equipped with an internal combustion engine of the volume 40 or 50 cm3. The machine is designed for racing circuits; not only for young riders but also for seniors. The innovation is in the design and verification of pressed connections in the imposition of major pins in the arms of the crankshaft. Pressed connections are designed on the basis of the analysis of force interaction on the crankshaft at maximum revolutions. The proposed solutions are verified by FEM calculations. Based on the results, the best option is selected. For the selected option, the impact of force interaction at maximum machine performance is studied. Finally, on the basis of these facts, designing, technological and economic analysis of feasibility of new production technology is carried out.

Structural design of the SOU Orbiter rack stacker
Těšický, Petr ; Molinari, Petr (referee) ; Škopán, Miroslav (advisor)
This thesis deals with rack stackers transporting pallets in rack channels. The goal is to make a competitive construction design of the given rack stacker. The thesis describes the principle of stacker function and the technical parameters of similar rack stackers. Subsequently, the structural design of the rack stacker, force analysis, kinematic analysis of the lifting mechanism and strength control of selected structural nodes are carried out. The drawing documentation is also a part of this diploma thesis.
