Patent ID: 8434607

Claim:
A torque transmitting device for selectively transmitting torque between a first member and a second member, the torque transmitting device comprising: an annular piston that defines an axis; an apply plate translatable along the axis between an unengaged position and an engaged position, the apply plate having a first end and a second end, wherein the first end is disposed radially inward of the second end and the first end is disposed in radial alignment with the second end, and wherein the first end is in contact with the piston; an apply disc rotationally coupled to the first member, wherein the apply disc is translatable between an unengaged position and an engaged position along the axis, and wherein the apply disc is disposed radially outward of the piston; a backing disc rotationally and axially fixed to the first member and disposed radially outward of the piston; and a friction plate disposed between the apply disc and the backing disc, the friction plate having a first end and a second end, wherein the first end is disposed radially inward of the second end, wherein the first end is rotationally coupled to the second member, and wherein the friction plate is disposed radially outward of the piston, wherein the torque transmitting device is engaged when the piston is pressurized and translates the apply plate, the second end of the apply plate contacts the apply disc, and the friction plate is compressed between the apply disc and the backing disc, thereby rotationally coupling the apply disc and backing disc with the friction plate.
