| Abstract | Automotive drivetrains are complex mechanical systems that generate a wide range of noise & vibration. Automakers are continuously working to improve or suppress the noise & vibration in order to meet the needs of the market for a quiet and comfortable car. JTEKT has developed & produced a small isolator which attaches to a roller thrust bearing for controlling the noise produced by the bearing or transmitted through it by the drivetrain. The developed product reduces noise on average by 10 dB and minimized the potential of increased weight. This report presents a revolutionary product which reduces application noise and vibration by the addition of an isolator to a conventional bearing. |
