Abstract: The present invention relates to a power generation system for a transportation vehicle. The power generation system includes an axle, a brake disc having a space in a center, a brake pad for applying braking force to the brake disc, a rotor installed on an inner surface of the space to face the axle and having a plurality of permanent magnets, a stator installed on an outer surface of the axle to face the rotor and having a coil, and a dust shield installed in a path between the brake pad and the rotor to shield dust from the brake pad. The present invention not only greatly increases the space utilization of a transportation vehicle, but also eliminates the need for separate wiring work to supply power from another vehicle.
