In transport engineering, the transmission system is an essential part of a vehicle鈥檚 drivetrain, ensuring efficient transfer of engine torque to the driving wheels. This bachelor鈥檚 thesis presents the design of a four-wheel-drive (4WD) transmission system for a VW Golf 7 passenger car equipped with a 1.4 TSI engine developing a maximum torque of 250 Nm. The thesis analyzes the structural solutions of 2WD and 4WD transmission systems, their advantages, disadvantages, and suitability for different operating conditions. Based on the performed analysis, a 4WD transmission system was selected to improve vehicle traction, off-road capability, and driving stability. The practical part of the thesis includes the design of the gearbox and final drive, calculation of the main geometric parameters, and selection of gear modules, shaft diameters, and bearings. Strength and durability calculations of the gears, shafts, and bearings were also performed, including an evaluation of contact and bending fatigue loads as well as the influence of dynamic effects on the transmission components. During the design process, 34CrNiMo6 steel was selected for the gears to ensure sufficient fatigue resistance. The results showed that the designed transmission components meet the required strength and reliability criteria under most operating conditions. The selected gearbox center distance is 71 mm, the gear width is 36 mm, and the calculated gear ratios range from 3.76 in first gear to 0.79 in fifth gear. The designed transmission system satisfies the technical and operational requirements and can serve as a basis for further design development.

This Master's thesis investigates the monitoring of particulate matter emissions from M3 class vehicles operating under urban conditions and the dependence of these emissions on operational parameters. The relevance of the study is determined by increasing urbanization and growing traffic flows, which contribute to the deterioration of air quality and pose significant risks to public health and the environment. Particulate matter is considered one of the most hazardous components of air pollution; therefore, the reduction of its emissions has become an important objective of contemporary transport and environmental policy. The aim of the thesis is to evaluate the patterns of particulate matter emissions from M3 class vehicles under real operating conditions and to determine their dependence on vehicle mileage and vehicle configuration through experimental research and statistical modeling. During the study, particulate matter concentration measurements were carried out under different engine operating modes, while the influence of vehicle mileage and operating conditions on emissions was analyzed. Statistical analysis methods, including correlation and regression analysis, were applied to assess the obtained data. The results of the study make it possible to identify the main factors influencing particulate matter emissions within the urban transport system and to provide recommendations for improving the environmental performance of public transportation. The thesis has practical significance in the fields of transport engineering and environmental protection, as it contributes to the development of more efficient fleet management strategies and solutions aimed at reducing air pollution. The thesis consists of an introduction, a review of the scientific literature, a methodology of experimental research, a research and analysis section, conclusions, and a list of references. The thesis comprises 92 pages, 19 figures, 2 tables, and 51 references.

Electric drive systems are becoming increasingly relevant in the development of lightweight, economical and less polluting vehicles. This final thesis presents the design of an electric go-kart prototype by selecting the main electric drive and structural components and evaluating their suitability for the intended loads. The structural solutions of go-karts are analysed, and the electric motor, controller and battery pack are selected. Calculations are also performed for the frame, rear axle, motor bracket, battery mounting plate and the transmission ratio of the main drive. It was determined that the selected electric drive system does not exceed the specified limits of 60 V and 23 kW, while the stresses in the main structural elements do not exceed the allowable values of the selected materials. The selected main drive transmission ratio is 2.73, and the theoretical maximum speed of the go-kart is approximately 90.38 km/h. The designed electric go-kart prototype meets the required technical requirements and can be used as a basis for further improvement of the structure.
