Abstract:
1. A shift apparatus for a dual clutch transmission, the apparatus comprising: a plurality of shift lugs, each of which is connected to a shift fork to transmit straight movement force to the shift fork, and is configured to move between a shift stage position and a neutral state position, the shift lugs being arranged around a first axis, wherein each shift lug comprises two opposing flanges, each of which is tapered in a radial direction toward the first axis; and a shift operating module comprising a first shaft and a second shaft, the first shaft being configured to rotate about the first axis, the second shaft being configured to rotate along with the first shaft and move linearly along the first axis with respect to the first shaft such that the linear movement causes a first one of the shift lugs to move to the shift stage position and the rotation causes a second one of the shift lugs to move to the neutral state position, wherein the shift operating module comprises a shift release roller connected to the first shaft, the shift release roller being configured to rotate about a second axis perpendicular to the first axis, and the shift release roller being further configured to be inserted between the two opposing flanges of the second shift lug upon rotation of the first shaft such that the second shift lug moves to the neutral state position.
