Analysis of technical-economic parameters of the tractor kits in transport
Krátký, Martin ; Slimařík, Dušan (referee) ; Bauer, František (advisor)
This thesis deals with the use of the tractor in agricultural transport. The first part describes the current status in construction of tractor engines, transmissions and chassis that are used in tractors suitable for transport. The theoretical section includes an overview of the legislative requirements that must be followed for the tractor kits in transport on the road. The main objective of this thesis was to evaluate a measuring of fuel consumption and efficiency of the tractor JCB Fastrac 185-65 with two flatbed trailers. For this purpose was created the methodics off terrain measurement, which were carried out for different operation modes of the engine. The results were tabular and graphical processing including determining the accuracy of the method by calculating the relative error of measurement. For comparison a theoretical calculation of the consumed fuel was made. The aim of the measurements was to demonstrate fuel-saving during operation engine in the economic field and get an overview about fuel consumption and efficiency kits.

Vliv huštění pneumatik na výstupní parametry traktorové soupravy
Dvořáček, Vojtěch
The thesis dealswith tractortires. It shows the different types of tires used in agricultural machinery. This work also includes field laboratory measurements. Theme asurement examines the dependence of the tire pressure on the output parameters of the tractor set. The examined output parameters were operational and efficient performance and operational and efficient fuel consumption. The controlled variable in the set was the tire pressure in the tractor. Values were recorded for the different tire pressure values. The measurement results are graphically represented and commented on.

Ekonomika provozu traktorových souprav v zemědělském popdniku LEDEKO Letovice
Kolářová, Jana
This diploma thesis deals with the economy of the tractor sets of the tractor CASE IH Magnum 280 and the tractor CASE IHPuma 230 CVX EP. The economy is considered with the selected agricultural machines operating by the processes of ploughing and stubble- tillage. The ploughing was done with with the six-and seven- blade plough Kverneland PG 100. The stubble-tillage was done with the disc stubble- plough Diskomat 6. The technical parametres of the tractor engines were taken from DLG- Top Agrar Test Heft Nr. 11/2003 and from CNH CASE PUMA 230 CVX/ DLG 2010-268. The diploma thesis contains energy and efficiency parametres of the tractor sets. The results are based on the one-year observations. The obtained parametres are elaborated in the forms of tables and graphs. The measured figures were used to present the technical - economic analysis.

Vliv stavebně technického řešení komunikace na bezpečnost silničního provozu
Fasora, Radek
Fasora, R., Influence of building technical solutions of roads for the safety of these roads. Diploma thesis. Brno: Mendel University in Brno, 2014. Thesis describes the conditions of using the traffic roads. It is concered with towed curves for validation of driving through the curves. Precisely it is aiming to proposing and creating templates of the towed curves for tractor sets.
