Firmly convex block pulls back octagon cylinder, moves backward octagon cylinder along small-size shaft, and drive limited block along limit
Slot moves backward, and when octagon cylinder is separated with octagon circular groove, pushes wheel hub to the right, drives wheel hub by main shaft and connects
Set moves right, and stretches to connecting shaft left end inside connector sleeve, so that small-size rack is meshed with gear, continuation is pushed to the right
Wheel hub makes connector sleeve that miniature gear be driven to move right, so that miniature gear is meshed with small-size rack, miniature gear is driven to turn
Dynamic, miniature gear rotation drives octagon cylinder and baffle rotation, is affixed when connecting shaft left end is moved to main shaft right side
When conjunction, stop pushing wheel hub, and decontrol octagon cylinder, in the case where spring two restores the elastic force effect of deformation, octagon cylindrical band
Dynamic limited block moves forward, so that octagon cylinder front end is moved to inside octagon circular groove, then small-size shaft cannot occur to turn
It is dynamic, realize the positioning of connecting shaft.
7. a kind of permanent magnet synchronous motor mounting structure of electric vehicle hub according to claim 5, it is characterised in that：It is described
Connector sleeve inner annular side front end and rear end offer locating slot, and connecting shaft annular side front end and rear end are equal
It is fixed with positioning convex strip, the positioning convex strip is mounted on inside locating slot, in use, passes through locating slot and positioning convex strip
Contraposition be attached the connection of axis and connector sleeve, improve engage accuracy of the miniature gear with small-size rack, and running
It avoids connecting shaft from relatively rotating with connector sleeve in the process, improves stability.
