Abstract
A variator assembly for a transmission includes an input shaft, an input disc, an output disc, a roller, a trunnion, a piston, and a connection member. The input shaft defines an axis of rotation and the input disc is rotationally coupled to the input shaft and coaxial with the axis of rotation. The roller is disposed between the input disc and the output disc to provide a speed ratio between the input disc and the output disc. The trunnion is connected to the roller and includes a connecting feature. The piston defines a central bore. The connection member has a head portion, a shaft portion, and a connecting portion, where the connecting portion is connected to the connecting feature of the trunnion, the head portion abuts the piston, and the shaft portion is disposed in the central bore of the piston.
