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.

    本发明提出了一种挂车无级混合励磁缓速器,具体涉及一种车辆非接触式辅助制动技术领域,包括外定子、永磁体、缓速器转子、定子铁心、磁轭、励磁绕组、伺服电机和喷油嘴;所述缓速器转子包括转子盘和转子套;所述永磁体表贴于转子套外表面;所述转子铁心安装在缓速器转子内部;所述励磁绕组缠绕在定子铁心上,转盘与转子套之间留有间隙,供励磁绕组外接接线柱。本发明的优点在于,所述缓速器可以通过制动踏板实现双重无级制动,即增加了制动力矩,也提高了制动力矩的控制精度;所述缓速器采用水冷加油冷的散热方式,散热效果好。
