Learning outcomes
|
Get students basic information about theory and construction of brake systems of rail vehicles. The sections are divided into parts of force behavior by braking, pneumatic and mechanic part of brake, construction and characteristic of each brake types and design of brake for concrete vehicle.
Student is able to consider the suitability of brake system for concrete rail vehicle from the point of view of vehicle parameters (weight, speed) and able to design the brake system according to requirements too.
