converter input shaft rotates When, converter input shaft can drive sun gear to rotate；Sun gear, which rotates, drives drive shaft turns；Drive shaft turns are limited by moment of torsion Device processed drives support thread spindle to rotate；Since thread bush by two guide blocks and two guide grooves is fitted to fixed installation shell It is interior；Thread bush passes through thread fitting with support thread spindle；So support thread spindle rotates and thread bush can be moved along guide groove； When the rotation for supporting thread spindle make it that thread bush is moved towards the first triggering support ring, in moving process, when installed in spiral shell When the annulus that rubs on line set is contacted with the first triggering support ring, friction annulus will extrude the first triggering support ring and cause first Triggering support ring remains static；I.e. three support shafts remain static；Sun gear, which rotates, at this time will drive three Star wheels index；Three star wheels index drive ring gear against rotation；Ring gear against rotation by the second gear ring connection ring and second surmount from Clutch drives output
