The invention discloses a power generation device for recovering braking kinetic energy of a rail wagon. The power generation device is arranged on a truck bogie, wherein the bogie comprises wheels, an axle body, a brake beam, a brake lever and a brake pull rod; a permanent magnet rotating along with the axle is fixedly arranged on the axle body, and an induction coil moving along with the brake beam and used for power generation is fixedly arranged at the position, corresponding to the permanent magnet, of the brake beam; the induction coil is arranged above or below the horizontal plane where the permanent magnet on the axle is located, and non-contact approaching of the induction coil and the permanent magnet is achieved. According to the device, during braking, the kinetic energy dissipated by an existing railway wagon can be converted into electric energy to be stored and utilized, so that the energy converted into heat energy to be dissipated is reduced in the braking process, the pressure and friction force needed between wheels and brake shoes are reduced, abrasion between the wheels and the brake shoes can be reduced through the consumed kinetic energy, and the service life is prolonged. The reasonable spatial layout enables the structure to be more reasonable and safer.
