1. A torque transmitting mechanism for a transmission, the torque transmitting mechanism comprising:
a first shaft rotatably supported on a first end by a stationary housing of the transmission through a first bearing, and wherein the first shaft includes a plurality of splines and an annular ring disposed in a groove at an end of the plurality of splines; a second shaft having a first and a second end opposite the first end, the first end of the second shaft is rotatably supported by the stationary housing of the transmission through a second bearing, the second shaft is a sleeve shaft having a bore, the second end of the second shaft includes a dog tooth end, and the first shaft is disposed in the bore of and coaxially with the second shaft; a rotating piston rotatably connected to the first shaft through a ball spline connection, and wherein the rotating piston includes a dog tooth end; a stationary piston disposed in the stationary housing of the transmission, and wherein the stationary piston and the stationary housing form a hydraulic fluid piston apply chamber; a third bearing disposed between the rotating piston and the stationary piston; a biasing member disposed between the annular ring and the rotating piston to bias the rotating piston towards the stationary piston; a third shaft, and wherein the first shaft is an output shaft, the second shaft is a transfer shaft coaxial with and partially covering the output shaft, and the third shaft is coaxial with the output shaft and transfer shaft, is partially disposed in the output shaft, and is connected for common rotation with the output shaft through a ball spline connection; a transfer gear fixed for common rotation with the transfer shaft; and wherein the dog tooth end of the second shaft is axially aligned and configured to selectively engage with the dog tooth end of the rotating piston and the output shaft further includes a splined portion meshing with an output gear. |
