1. A regenerative braking power generation system for trailers, the regenerative braking power generation system comprising:
at least one axle fixed to a chassis of a trailer;
a wheel hub and a brake disc axially installed at an outer surface of the axle via a plurality of bearings so as to be passively rotated; and
a generator installed in a space portion concavely formed in one side surface of the brake disc, wherein the generator comprises:
a ring-shaped rotor fixed to an inner circumferential surface of the space portion of the brake disc in tight contact therewith, the rotor having a plurality of permanent magnets disposed thereon at equal intervals; and
a stator fixed to an outer circumferential surface of the axle corresponding to the rotor, the stator being constituted by a stator coil.
