LINEAR GEAR SHIFT MECHANISM

摘要

A linear gear shift mechanism includes a support rotator; transmission balls movably disposed at the support rotator and each provided with a cylindrical recess along radial direction thereof; driving posts with inward ends movably disposed in the cylindrical recesses along the radial direction of the support rotator; a gear shift unit movably connected to outward ends of the driving posts to drive the driving posts to rotate from the radial direction of the support rotator to but not reach the axial direction of the support rotator; an axial power input rotator having an inward-tilted power input annular surface; and an axial power output rotator having an inward-tilted power output annular surface, wherein the axial power input rotator and axial power output rotator flank and movably clamp the transmission balls between the inward-tilted power input annular surface, inward-tilted power output annular surface and outer circumferential surface of the support rotator.

1. A linear gear shift mechanism, comprising:
a support rotator; a plurality of transmission balls spaced apart from each other and movably disposed on an outer circumferential surface of the support rotator, with a cylindrical recess disposed on each said transmission ball along a radial direction thereof; a plurality of driving posts with inward ends movably disposed in the cylindrical recesses along a radial direction of the support rotator; a gear shift unit movably connected to outward ends of the driving posts and adapted to drive the driving posts to rotate from the radial direction of the support rotator to but not reach an axial direction of the support rotator; an axial power input rotator having an inward-tilted power input annular surface; and an axial power output rotator having an inward-tilted power output annular surface, wherein the axial power input rotator and the axial power output rotator are disposed on two opposite sides of the transmission balls to movably clamp the transmission balls between the inward-tilted power input annular surface, the inward-tilted power output annular surface and the outer circumferential surface of the support rotator.
