Title: DISC WITH INSERTABLE PINS AND METHOD OF MANUFACTURE FOR SAME
Abstract:
A disc for controlling tilt angle for a plurality of axles in a ball planetary continuously variable transmission (CVT) is provided. A disc body is formed and pins are inserted to create slots. Each slot can be configured for contact with one end of an axle of a traction planet. The pins may be made from a different material or otherwise have different characteristics or properties than the disc body, allowing greater availability of materials that can be selected for forming the slots. The pins can be simple (such as a straight, cylindrical shape) or complex (including a complex curve of different diameters, multiple surfaces, and the like. A manufacturing process for a disc may include forming a disc body using a first process and then adding or removing material using a second process, then inserting pins into the disc body.
