Revolutionary "Active Wheel"

Revolutionary "Active Wheel" TIRES/WHEELS Miscellaneous 29-5-40 Michelin has another first-of-its-kind product that might have even more potential than the "Tweel." The Active Wheel is designed to eliminate brake systems, transmissions, differentials and even frame suspension. Company managing partner Edouard Michelin has been quoted as saying, "Why not use the space within the tire to put as many components as possible, including all suspension, and make it active with an electric motor that eliminates the need for a mechanical transmission." Use the space is just what the Michelin researchers did. Each Active Wheel contains a permanent magnet electric motor, a disc brake and an active suspension system. The electric motors provide both acceleration and braking. When braking, the wheel motor switches from user to generator mode, storing power for the next acceleration. The electronically controlled suspension allows the car to instantly adjust from luxury sedan smooth to sports car firm. So far the Active Wheels have been showcased in two prototype cars developed by Michelin. The Hy-Light is hydrogen fuel cell powered, while the Concept is a gas/electric hybrid. While Michelin says they have no intention of building cars, the revolutionary all-in-one wheel units could certainly change how car makers do business. "Active Wheels are at the prototype stage," says Lynn Mann, director of public relations, Michelin North America. "No costs have been identified yet. The next stage is to interest others in the technology." Contact: FARM SHOW Followup, Michelin Consumer Relations Dept., P.O.
