What Happened to Torque Tubes? The Enclosed Driveshaft System Early Cars Once Depended On

#MechanicalEngineering #AutomotiveHistory #ForgottenTechnology What happened to torque tubes, the enclosed driveshaft system that millions of early American cars once depended on? From the Ford Model T to classic Buicks and Chevrolets, this forgotten mechanical technology helped transmit power, control rear axle movement, and deliver a smoother ride. So why did automakers eventually abandon it? Discover how the torque tube drive worked, from its enclosed driveshaft and universal joint to the rigid housing that transferred driving forces through the vehicle. Explore how Henry Ford helped popularize the system, why Buick relied on it for ride comfort, and how it became a defining feature of early automotive engineering. Learn why increasing highway speeds, added weight, drivetrain vibrations, maintenance challenges, and the rise of the Hotchkiss drive eventually pushed torque tubes out of mainstream American cars. We'll also explore how this seemingly forgotten technology found new applications in performance cars, including Porsche, Corvette, and Aston Martin.
