Abstract

A planetary gearset is provided in a transmission for a vehicle. The planetary gearset includes a carrier that rotates about the axis. Tone wheels can be used as part of a speed-sensing mechanism in which the tone wheel includes surface features on an outside surface, and a speed sensor senses the surface features as they rotate about the axis and past the speed sensor. The tone wheel is connected to the carrier via a press-fit or interference-fit. To do so, the tone wheel includes legs or flanges that extend inward from an inner surface of the tone wheel. The legs or flanges flex as the tone wheel is pressed onto the carrier. The legs or flanges securely attach the tone wheel to the carrier.
