Study of torque vectoring clutch design
Cupák, Václav ; Porteš, Petr (referee) ; Fojtášek, Jan (advisor)
This work deals with the design of right and left torque vectoring control used in heavy commercial vehicle powertrains. The beginning of the work is focused on the description of the active differential system and on the clutches used in the automotive industry. Then the basic parameters of the experimental vehicle are defined and the choice of the clutch conception is made. Subsequently, calculations of geometric parameters of clutches and verification of their heat capacity is made. Conceptual design of the control mechanism is discussed in the last chapter. The aim of the work is the draft of the possible type of control mechanism for the given system with the possibility to use the information obtained for the further development of this system.

Piston Rings of Modern Petrol Engines
Cupák, Václav ; Maršálek, Ondřej (referee) ; Raffai, Peter (advisor)
This bachelor thesis deals with issues of piston rings used in modern petrol engines. The first part is focused on describing of functions and requirements with which piston rings must deal with. Next part is aimed on shapes of piston rings. Materials from which are piston rings made of are part of third chapter. For proper function, it is important to make some surface treatment. The last chapter contains surface treatment of piston rings.
