the cooling mechanism comprises a No. inner circular tube, a No. outer circular tube, a No. two inner circular tube and a No. two outer circular tube, the No. inner circular tube is positioned in a No. outer circular tube, the No. two inner circular tube is positioned in the No. two outer circular tube, the left end surface of the No. inner circular tube and the left end surface of the No. outer circular tube are respectively and fixedly connected to the right surface of the circular ring block in a sealing manner, the right end outer wall of the No. inner circular tube is rotatably connected to the left end inner wall of the No. two inner circular tube in a sealing manner, the right end surface of the No. outer circular tube is rotatably and fixedly connected to the left end inner wall of the No. two outer circular tube, and an annular cooling liquid is arranged in the annular cooling cavity, and the axis of the No. inner circular tube, the axis of the No. outer circular tube, the axis of the No. two inner circular tube and the axis of the No. two outer circular ring block fall on the axis of the No. two outer circular shaft;

the clutch disc (33) is positioned at the left of the circular ring block (41);

when braking is needed, the microcontroller respectively sends corresponding starting instructions to the magnet exciting coil and the air pump, the magnet exciting coil is electrified immediately, the air pump presses high-pressure air into the annular piston cavity, thereby enabling the thrust bearing in the circular piston cavity to move rightwards, the thrust bearing drives the clutch disc to move rightwards, the clutch disc drives the friction plate to move rightwards, the friction plate is connected on the circular block in a pressing contact way after moving rightwards, the circular block is driven by the rotating friction plate to rotate, after the transverse block and the circular block cut magnetic lines of force sent by the excitation coil on the stator, eddy currents are generated in the transverse block and the circular block, the eddy currents in the transverse block can generate torque for preventing the transverse block from rotating, the eddy currents in the circular block can also generate torque for preventing the circular block from rotating, the blocking torque is transmitted to the transmission shaft to form a braking torque blocking the rotation of the transmission shaft, so that the rotation speed of the transmission shaft is reduced;

the magnet exciting coil is arranged on the stator drum of the stator; the permanent magnet is arranged in a block groove on the transverse block of the rotor.
