The axial distance (LM) of the follower jaw (56, 58) is at least twice the axial distance (LF) of the selector pin (48, 50), so that the selector shaft (42) can be moved back into a neutral position (N) when changing from a starting gear to a target gear whilst the starting gear is still engaged. The selector device for engaging and disengaging the gears comprises a rotatable and axially movable selector shaft extending parallel to the transmission shafts and provided with a number of radially protruding selector pins. The selector device also includes a number of selector parts which can be axially slid or pivoted in order to engage or disengage the gears, each of these parts including a follower jaw for receiving a selector pin in order for the part to move with the pin in the axial direction. An Independent claim is also included for a shift method for this transmission, comprising the shifting of the selector shaft into a neutral position without disengaging the starting gear, rotating the shaft until its position corresponds to that of a selector part associated with the target gear and shifting the shaft so that the starting gear is disengaged and the target gear is engaged. |
