6MT reverse gear latching mechanism and 6MT speed changer

The invention provides a 6MT reverse gear latching mechanism. The whole 6MT reverse gear latching mechanism is located in a speed changer. The reverse gear latching mechanism comprises a ratchet wheel and a pawl, the ratchet wheel is installed on a gear shifting shaft, the pawl can be occluded with the ratchet wheel, and the pawl is mounted on a 3/4 gear fork frame. When a gear shifting finger puts into a fourth gear, the gear shifting finger drives the ratchet wheel to rotate, the ratchet wheel blocks a gear shifting limiting pin, and thereby, the gear shifting finger can not further move to a gear shifting position of a reverse gear when located at a gear shifting position of a 5/6 gear. According to the 6MT reverse gear latching mechanism, the whole 6MT reverse gear latching mechanism is located in space defined by interlocking plates, and thereby, defects that gear shifting comforts are affected when traditional reverse gear latching mechanisms are designed on gear shifters are overcome; besides, the whol
