Abstract
A torque transmitting device for transmitting torque between a first and second members includes an annular piston that defines an axis and an apply plate translatable along the axis between an unengaged position and an engaged position. The apply plate has a first end disposed radially inward of a second end and is in contact with the piston. An apply disc is rotationally coupled to the first member and is translatable between unengaged and engaged positions. The apply disc is disposed radially outward of the piston. A backing disc is rotationally and axially fixed to the first member and disposed radially outward of the piston. A friction plate is disposed between the apply disc and the backing disc. The friction plate has a first end disposed radially inward of a second end and is rotationally coupled to the second member. The friction plate is disposed radially outward of the piston.
