Cable winch
Kudláček, Miroslav ; Kašpárek, Jaroslav (referee) ; Malášek, Jiří (advisor)
The goal of my bachelor´ s thesis is to find a construction solution for a cable winch for a safe take-off of model gliders of a wingspan of maximum 5 m, a weight of 5kg and with a maximum take-off speed of 17 m.s-1. The thesis includes a project of a winding drum, including a control calculation, alternatives, the choice of a drive unit and a ductile element and a project of a frame.

The redesign of the compressor for electromotor driving
Mikulka, Vít ; Venclík, Jiří (referee) ; Mazůrek, Ivan (advisor)
This bachelor thesis deals with redesign of the compressor for electromotor driving. First part focuses on the principle of compressors, their development and division. The next part describes a compressor MK 100 produced by Benda kompresory Ltd. company. The technical solution of its redesign for 2,2kW electromotor propulsion with maintaining a rotation speed mode of original Honda engine is explained in the last part. This compressor should be used in its redesign version at FME BUT in Brno.

Design of electric tackle
Bádr, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
Purposes work was create technical documentation to an electrically driven tackle with actuated by hand undercarriage. Was booked up fundamental parameters like bearing, stroke and hoisting speed. First was effected calculation of load on pinion necks and an idle pulley. Subsequently was effected calculation for right election of a rope, an idle pulley, a rope drum and bearings for the rope drum. Up this calculation followed calculation for a right election of an electric motor and a shaft clutch. The documentation was complemented with pictures and tablets, that are seted near single decisive knots of the tackle. To the documentation was creationed how a suggested arrangement drawing so single subassemblies drawings.

Sacristian bell operation control by programmable logic controller
Křížek, Ladislav ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
The bell is described, its parts and constructive suppositions for the right function in this work, sacristian bell operation control with hand-working and with the rotating electromotor. Programmable logic controller machine SIEMENS Simatic S7-200 CPU 221 is also described, which is the part of ringing machine in Bukovinka’s church. This ringing machine and especially the mode of both bells have specific defect. According to owner´s wishes and instructions were two variants prepared for this ringing machine to improve the working of couple bells. One of these variants was tested and just tuned at the ringing machine. This one variant follows the owner´s wish, works in Bukovinka´s church till now.

Konstrukce elektrického motocyklu
Dobeš, Jan
In diploma thesis Construction of electric motorcycles I deal with issue of electric motorcycles, their types, constructions, advantages and their use. One part includes description of tractions and transmissions. Next part describes batteries, which are necessary in electric vehicles. The aim of this work is to compare different solutions of vehicle constructions. Experiment is about two constructions of quad. This quad used combustion engine and was modified to electric power. Electric quad was tested on power testing stand. Experimental quad constructions which were used were compared and evaluated. Experiment included test of stamina of fully charged battery.

Alternativní pohony motorových vozidel
Puchnar, Lukáš
This Bachelor thesis focuses on the possibilities of using alternative fuels to operate the vehicle. In the first chapters, there is a review of fossil fuels used, its properties and monitored emission parameters. The following section is devoted to gas fuels, problems associated with the storage in the vehicle and engine modifications. Further are descri-bed biofuels, its production and application in combustion engines. Subsequently the electric vehicles is briefly described, current state and performance characteristics of this type of vehicles. The distribution of hybrid vehicle propulsion systems follows. The final section focuses on the economic comparison of selected alternative drives, its af-fordability and costs of operation.
