When the rotating cockpit or the motor tries to rotate, it will cause the upper and lower disks to form a small angle misalignment. At this time, the attraction between the magnets will be at Tangentially generates a torque that prevents the dislocation of the upper and lower disks. When this torque is large enough, we can use it to achieve the purpose of locking the upper and lower disks and achieve synchronous rotation. At this time, the upper and lower disks are equivalent to the function of a magnetic clutch, linking the motor and the slewing bearing, thereby linking the rotating cockpit and the motor. Then at this time, the motor starts to drive the rotating cockpit to rotate, which is the adjustment function; when the motor is locked, the upper frame will also be locked, which is the locking function.

2. Non-contact magnetic speed limit function:

When the car body slides freely on the track and the chassis slides freely along the track, the rotating cockpit will rotate 360° freely relative to the chassis due to inertia, but in order to ensure the comfort of passengers, the maximum speed of rotation must be controlled, which used to be Using purely mechanical brakes to limit the speed has problems of maintenance and wear. And this device is a kind of non-contact damping mechanism, when the car body slides freely, the magnetic disk is in disengagement state. Due to the linkage between the rotating cockpit and the rotating shaft gear 10, the rotating cockpit will drive the upper disk to rotate, but the annular damping plate 9 does not move, and the two groups of magnets on the upper disk form vertical magnetic lines of force in the space of the annular damping plate 9. When the disk and the ring-shaped damping plate 9 rotate relatively, the ring-shaped damping plate 9 cuts the magnetic force line in this magnetic field, and an eddy current is generated in the ring-shaped damping plate 9. Due to the principle of electromagnetic induction, an electromagnetic damping will be generated between the ring-shaped damping plate 9 and the upper disk. Torque, to prevent the relative rotation of the annular damping plate 9 and the upper disk, and the greater the relative rotational speed, the greater the damping torque. The above is the case where the disk is disengaged. In fact, since the damping disk is always in the magnetic field of the upper disk, magnetic damping exists at any time.
