Make up two separation and reunion mechanical transmission of built -in clutch mechanism

The utility model provides a make up the mechanical transmission of built -in double clutch mechanism, including one -level driving gear, secondary drive gear, motor, one -level driving gear, secondary drive gear's side is furnished with with the gear integratively by the pressure disk to set up the initiative pressure disk on corresponding gear shaft, operating mechanism arranges at the hollow shaft intraductally. The utility model discloses a make up the mechanical transmission of built -in double clutch mechanism, the variable speed delivery vehicle (vehicle, aircraft, boats and ships) and other energy -saving and speed -regulating that are applicable to more gears equip, simple structure, and the part number is few, through disposing a plurality of the same variable speed units, many grades variable speed demand, not high to the requirement of machining precision, manufacturing cost is the half of pair separation and reunion derailleurs at present. Because adopt servo motor to work as required, its transmission efficiency improves more than 10% than current two separation and reunion derailleurs.
