Course objectives supported by learning outcomes
Students acquaint with function and construction of propulsion and energy transmission systems of machines with combustion and electric motors, hydrodynamic aggregate, open and closed hydrostatic circuit and pneumatic drives. To obtain so knowledge and acquirements necessary for practical decision making with choice drive machines system and for functional design of these systems, leading to choice functionally and energic optimum component of catalogue specialized producers.
Learning outcomes
The student is able to make a comprehensive assessment of the machinery drive.
