Inner sleeve 9 is connected.
When this speed changer is coupled, coupling principle is exactly Faraday's electromagnetic induction law, i.e., when conductor disc and permanent magnetism
There are during speed discrepancy between body disc, the magnetic line of force of the copper ring cutting permanent magnet of conductor plate inlaid senses so as to produce induced field
Attraction and repulsive force are produced between magnetic field and the permanent magnetic field of permanent magnet, both make a concerted effort be tangentially on power, it is pushed away
Dynamic permanent magnetism body disc rotates, so as to be coupled.With reference to the accompanying drawings 1, its coupling process is：The power of prime mover passes through plum coupling
