Six-speed Transmission Baffle Assembly
A thermoplastic elastomer (TPE) single-piece, six-speed transmission baffle assembly, replacing the incumbent stamped steel with bonded rubber seal. Developed with the Ford Motor Company for use on its 2018 Ford Focus.
Material improvements to transmission baffle assembly components offer opportunities for weight reduction, cost reduction and improved fuel efficiency, as well as noise, vibration and harshness (NVH) improvements.
The part was produced using a one-step injection molding process, enabling integrated seal elements capable of sealing with a cast surface. Snap-fit assembly behavior allows the part to effectively seal five areas.
