摘要： A vehicle transmission has first and second shafts rotatable in a housing, a spring applied, pressure released bake mechanism for preventing vehicle movement, and a torque disconnect mechanism for controlling transmission of torque from the first shaft to the second shaft. An interlock mechanism includes an opening formed in the housing through which an operator may access the torque disconnect mechanism, a fluid pressure supply passage for communicating pressurized fluid to the brake mechanism, a dump port formed in the housing in a wall of the opening, a pressure dump passage communicating the supply passage with the dump port, and a plug member mountable in the opening. The plug member closes the dump port and closes communication between the dump passage and the environment when the plug member is mounted in the opening The dump port and the dump passage are communicated with the environment, and the brake is spring applied when the plug member is removed from the opening.

摘要： A torque disconnect mechanism controls transmission of torque from a first shaft to a second shaft in a transmission. The mechanism includes a housing which rotatably supports the first and second shafts, and which has an opening formed therein. A coupling member is movable from an engaged position wherein the coupling member couples the first shaft with the second shaft to a disengaged position wherein the first and second shafts are uncoupled from each other. A plug member is mountable in the opening and is engagable with the coupling member. The plug member is movable from a first position holding the coupling member in its engaged position to a second position holding the coupling member in its disengaged position.
