Patent ID: 8858389

Claim:
A transmission comprising: a transmission housing having a valve body portion and a substantially planar surface that defines an opening; a variator assembly disposed adjacent to the valve body portion of the transmission housing, the variator assembly comprising: a first support member; a second support member; an input shaft disposed substantially perpendicular to the substantially planar surface of the transmission housing, wherein the input shaft defines an axis of rotation and extends axially through the opening defined by the planar surface of the transmission housing; an input disc rotationally coupled with the input shaft and coaxial with the axis of rotation; an output disc opposing the input disc and coaxial with the axis of rotation; a roller disposed between the input disc and the output disc to provide a speed ratio between the input disc and the output disc; a trunnion having a first end and a second end, wherein the trunnion rotatably supports the roller, the first end is pivotally supported by the first support member, the second end is pivotally supported by the second support member, and the trunnion further defines a pin bore offset from an axis of rotation of the trunnion; and a piston that defines a central bore and a pin, and wherein the pin of the piston is disposed in the pin bore of the trunnion; and a torque converter including a turbine that is directly rotationally coupled with the input shaft of the variator assembly; a housing support member including a substantially planar surface, wherein the housing support member is attached to the transmission housing and the substantially planar surface opposes the substantially planar surface of the transmission housing; and wherein the first and second support members of the variator assembly are fixedly attached to the housing support member and the valve body portion of the transmission housing further includes a plurality of piston pockets.
