Abstract:
A case cover assembly to which a sheave for a continuously variable transmission is mountable for rotation about an axis is configured to provide fluid communication between the sheave and a pressurized fluid source. The case cover assembly includes a conduit defining a first segment of a passageway for providing fluid communication between the pressurized fluid source and the sheave. An inner annular surface and an outer annular surface define an annular second segment of the passageway. A chamber at least partially formed by a case cover member defines a third segment of the passageway. The third segment is positioned with respect to the second segment such that fluid flows radially inward toward the axis from the second segment. The radial inflow provides improved pressure transference and packaging compared to the prior art.

Abstract:
A case cover for a continuously variable transmission includes a wall having a plurality of fastening elements thereon and at which a sheave assembly is rotatably mountable. The wall forms at least a portion of a cavity for containing at least a portion of the sheave assembly. Two surfaces define a slot that is configured to position and positively locate a portion of the bearing retainer to result in coarse alignment of bearing retainer fastening elements with the case cover fastening elements. The bearing retainer fastening elements are preferably protruding nuts, and the case cover fastening elements are preferably tapered holes configured to further align the nuts for engagement with threaded fasteners.
