The present invention relates to a shift apparatus for a dual clutch transmission. The shift apparatus comprises a plurality of synchronizers (S1,S2,S3,S4) arranged around a first sub-shaft (23) or a second sub-shaft (24), such that the synchronizers (S1,S2,S3,S4) are interposed between slave gears (D1,D2,D3,D4,D5,D6,D7,DR) which are engaged with driving gears (G1,G2,G3,G4,G5,G6,G7) connected to a first input shaft (21) or to a second input shaft (22) connected to a first clutch (C1) and to a second clutch (C2) of a dual clutch (11); a plurality of shift forks (41,42,43,44) which is connected to the respective synchronizers (S1,S2,S3,S4), and which has respective follower pins (41c,42c,43c,44c); and a cam (50) which is connected to the follower pins (41c,42c,43c,44c) of the shift forks (41,42,43,44), and which has a cam groove (51) formed along an outer surface thereof. The cam (50) is connected to the follower pins (41c,42c,43c,44c) of the shift forks (41,42,43,44) in such a way that the follower pins (41c,42c,43c,44c) are arranged along the cam groove (51). The cam shifts the follower pins (41c,42c,43c,44c) to move the shift forks (41,42,43,44) and thus to enable the synchronizers (S1,S2,S3,S4) to be coupled to the slave gears (D1,D2,D3,D4,D5,D6,D7,DR). Thus, shifting control operations can be performed in an easy, smooth, and efficient manner, thereby providing vehicle occupants with comfort. |
