Abstract

Disclosed is a gear-driven assembly of transmission gear shifting. The gear-driven assembly comprises: a plurality of driven bevel gears engaging with the driving bevel gears of the gear- driving assembly, respectively; a driven shaft formed with at least one slit in an outer peripheral surface thereof in a longitudinal direction thereof, and having at least one ratchet installation section along an extension line of the slit; a sliding member inserted into the slit to slide to the ratchet installation section in a longitudinal direction of the ratchet installation section; and a plurality of ratchets installed between the ratchet installation section of the driven shaft and a coupling groove of the driven bevel gear such that the ratchets have elastic restoring force, in which the ratchets entirely or partially engage with the coupling groove by performing rotation as the ratchets make contact with the sliding member. Further, each driven bevel gear is coupled with the driven shaft and is formed with the coupling groove in an inner peripheral surface thereof.

Description

technical field [0001] The invention relates to a gear driven assembly of a transmission gear shifting device. More particularly, the present invention relates to a gear driven assembly of a transmission gear shifting device comprising a gear drive assembly having a plurality of driving bevel gears arranged concentrically with different numbers of teeth, and having a plurality of driven A driven bevel gear is mounted at the driven shaft so that the driven bevel gear engages the drive bevel gear in a gear follower assembly. Background technique [0002] Generally, a transportation device such as a bicycle moves using a driving force transmitted through its pedals. The driving force using the pedals is transmitted to the rear wheel through the chain. However, in such a bicycle having the above structure, the chain is repeatedly released during power transmission, so that power transmission efficiency may deteriorate, and thus, the chain may be separated from the bicycle. ...
