Abstract
An outer race assembly for a continuously variable transmission includes a hydraulic cavity housing, a first radially outer race structure spaced along an axis from a second radially outer race structure to form a radially outer race, and planetary members in rolling contact with the radially outer race. The first radially outer race structure includes nesting engagement with the hydraulic cavity housing, and a hydraulic cavity sealed between the hydraulic cavity housing and the first radially outer race structure to control axial movement of the first radially outer race structure.
