Synchromesh automatic transmission

摘要

A synchromesh automatic transmission includes a lug lock portion which is engaged with a shift lug separately from a shift finger and enables a shift fork to be controlled so as to be located at a neutral position, a shift selector mechanism which achieves a target shift stage by engaging the shift finger with the shift lug of the shift fork corresponding to the target shift stage and displacing this shift fork in a shift direction, and an interlock mechanism which controls a shift fork that is different from the target shift stage so as to be located at a neutral position by displacing the lug lock portion following movement of the shift finger in a selection direction and engaging this lug lock portion with the shift lug of the shift fork that is different from the target shift stage.
