The invention provides a trailer stepless hybrid excitation retarder, and particularly relates to the technical field of vehicle non-contact auxiliary braking, the trailer stepless hybrid excitation retarder comprises an outer stator, a permanent magnet, a retarder rotor, a stator iron core, a magnet yoke, an excitation winding, a servo motor and an oil nozzle; the retarder rotor comprises a rotor disc and a rotor sleeve; the permanent magnet body is attached to the outer surface of the rotor sleeve; the rotor iron core is installed in the retarder rotor. The excitation winding is wound on the stator iron core, and a gap is reserved between the rotating disc and the rotor sleeve so that the excitation winding can be externally connected with a binding post. The retarder has the advantages that the retarder can realize double stepless braking through the brake pedal, so that the braking torque is increased, and the control precision of the braking torque is also improved; the retarder adopts a water-cooling and oil-cooling heat dissipation mode, and the heat dissipation effect is good.
