Transmission gear shifting structure assembly

The invention discloses a transmission gear shifting structure assembly which comprises a gear shifting shaft and a gear shifting board used for driving a shifting fork. The gear shifting shaft circumferentially drives the gear shifting board to swing around the gear shifting shaft. By the adoption of the gear shifting structure that the gear shifting shaft directly drives the gear shifting board and drives the shifting fork, the structures of a gear shifting drum and the like which are commonly used in the prior art are omitted, case manufacture tends to be simplified, the whole structure is simple and compact, the requirement for manufacturing accuracy is not high, the whole structure of a gear shifting mechanism is simplified, the whole structure of a transmission is simple, the weight is reduced, and energy conservation and consumption reduction are facilitated.
