When automobile needs auxiliary braking, electric-control system sends instruction, and the drive end of control drive mechanism 400 stretches out, band
Dynamic stator 300 moves to the direction close to rotor 100.When stator 300 enters the annular accommodating chamber 150 of the rotor 100,
The magnetic line of force caused by the rotor 100 of the outer circumference surface cutting rotation of stator 300, current vortex is formed in the induced inside of stator 300, by
Lenz's law knows that the magnetic field force caused by the induced-current on motion conduct always revolts the motion of conductor, so as to generate system
Dynamic effect.The length for entering the annular accommodating chamber 150 of rotor 100 with stator 300 becomes larger, stator 300 and rotor 100
Between active area continue to increase, braking torque also becomes larger, and also by small increase, resistance rotor 100 moves induced-current

Kinetic energy, play decelerating effect.The recirculated water that heat caused by stator 300 is water cooled in chamber 320 absorbs and taken away, and rotor 100 produces
Raw heat is taken away by the radiation tooth 122 being arranged in the outer circumference of the outer shroud 120 of rotor 100 by air.When automobile is not required to
When braking, electric-control system sends instruction, and the drive end of control drive mechanism 400 is retracted, and drives stator 300 to away from rotor
100 direction motion, until the stator 300 leaves the annular accommodating chamber 150 of the rotor 100 completely, there is no sensing
Electric current produces, and brake force disappears.By control drive mechanism 400 drive end it is flexible, to adjust moment of torsion increase and decrease, control braking
The size of power, and then rotating speed of transmission shaft is controlled, reach the purpose of deceleration.
Cartridge type liquid cooling permanent-magnetic retarder of the present invention, the big shortcoming of current vortex retarder power consumption is overcome, by high property
The Nd-Fe-B permanent magnet of energy provides magnetic field, it is not necessary to powers, saves power supply.Axial force can preferably be overcome using core structure,
And small volume, application are wider.Its use rotor be set in stator outside structure, by polylith permanent magnet be embedded in turn
Sub- inner side, avoids permanent magnet from being thrown out of, and feather key is set on the mandrel of the relatively small stator support of profile, on the inside of stator
Guide groove is set, and drive mechanism promotes stator movement, is moved axially when overcoming liquid cooling permanent-magnetic retarder braking in the prior art
The unbalanced defect of Stator forces, and need driving force it is smaller.The cartridge type liquid cooling permanent-magnetic retarder is in stator interior
