Transfer for four-wheel drive vehicle

A transfer for a four-wheel drive vehicle, comprising:

• an input shaft;
• a first output shaft disposed coaxially with respect to said input shaft;
• a ring gear which co-rotates with said input shaft;
• a first pinion meshed with said ring gear;
• a second pinion in mesh with said first pinion at all times;
• a carrier rotatably supporting said first and second pinions;
• a sun gear, which extends axially of said first output shaft, for having one end thereof selectively meshed with said first pinion or said second pinion by said sun gear being slid axially of said first output shaft in response to an applied operation;
• a brake capable of locking a second end of said sun gear when the first end of said sun gear is at a position where it will mesh with said first pinion;
• a driving gear for meshing with the second end of said sun gear when the first end of said sun gear is at a position where it will mesh with said second pinion;
• a sleeve mounted on said first output shaft so as to be capable of engaging with said first output shaft in a direction of rotation and of being shifted along said first output shaft axially thereof, said sleeve being shiftable so that said driving gear can be engaged with said first output shaft in the direction of rotation;
• a second output shaft disposed in parallel with said first output shaft;
• a driven gear, which is provided on said second output shaft so as to co-rotate therewith, for having power transmitted thereto from said driving gear.

• a sun gear, which is shifted axially of said first output shaft, for being selectively meshed with said first pinion or said second pinion;
• a locking/unlocking unit locking said sun gear against movement;
• a second output shaft, which is disposed in parallel with said first output shaft, for selectively transferring torque to said first output shaft or said sun gear,
• a driving gear disposed on said first output shaft rotatably in unison with or relative to said first output shaft, said driving shaft transmitting torque to said second output shaft;
• and
• synchronizing means for cousing said driving gear to co-rotate with said sun gear or said first output shaft.
