摘　　要：该型号永磁缓速器是通过一个气隙调节机构,实现了制动力矩的无级调节,设计思路来源于某型号车辆主离合器的分离装置。在车辆行驶过程中,转子磁盘随传动轴一起转动,在初始位置时,定子盘距离转子盘较远,不产生制动力矩,使用缓速器制动时,转动旋转拨叉,带动两个活动盘转动一定的角度,转动过程中弹子槽由深变浅,产生一个推力矩,推动活动盘即定子盘向转子磁盘接近,开始切割磁力线,进一步产生了制动力矩。The permanent magnet retarder realizes stepless adjustment of braking torque through an air gap adjusting mechanism.The design idea comes from the separation device of the main clutch of a certain vehicle.In the process of vehicle,the rotor disk with the drive shaft rotation,when the initial position,the stator rotor disc plate distance for away,do not produce braking torque,brake using retarder,turn the rotating fork,driven plate of a certain rotary Angle of two activities,in the process of turning billiard slot from deep to shallow,generate a driving torque,promote activities offer the stator to the rotor disk is close to,Starting to cut the magnetic field lines,further creating a braking torque.
