[0026] Working principle:

[0027] Assembly stage

[0028] By turning the threaded rod 803 on the centrifugal block 603, the threaded plate 803 pushes the blocking block 801 on the connecting block 802. The tail of the blocking block 801 will deflect on the centrifugal block 603, so that the distance between the outer wall of the blocking block 801 and the inner wall of the upper drum 1 is adjusted, and the upper drum 1 and the lower drum 2 are connected.

The bolts are used to pass through the threaded holes 10 on the upper drum 1 and the lower drum 2 to fix them to the motorcycle frame.

[0029] Work status

[0030] The external power of the motorcycle drives the drive shaft 5 to rotate, which in turn drives the turntable 601 to rotate. When the drive shaft 5 rotates to a speed greater than the specified value, the centrifugal block 603 generates centrifugal force at the first connecting cap 602. The turntable 601 throws the centrifugal block 603 out through the first connecting cap 602, thereby creating resistance between the blocking block 801 on the centrifugal block 603 and the upper drum 1. This causes the turntable 601 and the drive shaft 5 to rotate synchronously, but the resistance slows them down. The centrifugal block 603 will pull the tension spring 7 on the connecting block 802 to deform and extend. When the drive shaft 5 rotates to a speed less than the specified value, the tension spring 7 on the second connecting cap 9 pulls the centrifugal block 603 on the connecting block 802 to move and reset to its original position. This improves the performance of the device.
