The invention discloses a trailer power taking device, and belongs to the technical field of train power supply. The device comprises a friction wheel generator and an elastic supporting mechanism, wherein the friction wheel generator comprises a rotor part and a stator part; the rotor part comprises a friction rubber ring, a barrel-shaped shell, a disc-type rotor cover and a permanent magnet, the stator part comprises a stator shaft, a stator iron core and a coil winding, the stator part is sleeved in the barrel-shaped shell, and two ends of the stator shaft penetrate through the barrel-shaped shell and the rotor cover to be fixedly connected with the elastic supporting mechanism. The elastic supporting mechanism is used for providing spring supporting force for the friction wheel generator to press the trailer hub. Power is taken through friction force, the structural characteristics of the trailer hub are not changed, safe operation of a trailer is guaranteed, and the trailer hub is safe and convenient to repair and maintain.
