BorgWarner has released further information on its clutch modules supplied to Hyundai, for its eight-speed automatic front-wheel drive transmission. Engineered to optimize efficiency and reduce drag, BorgWarner’s new clutch module helps the eight-speed transmission improve fuel economy 7.3% compared with the existing six-speed automatic transmission. The transmission debuted on the 2016 Kia K7 (known as the Cadenza in the United States) and Hyundai Aslan sedans, built for markets around the world.
“BorgWarner is pleased to expand our transmission business with Hyundai from friction packs and one-way clutch assemblies for the 6-speed transmission to our advanced clutch modules for Hyundai’s new fuel-efficient 8-speed transmission,” said Robin Kendrick, president and general manager, BorgWarner Transmission Systems. “For over 20 years, BorgWarner has demonstrated its ability to deliver innovative and reliable components to Hyundai and Kia with local production and support.”
Reducing the overall length and weight of the transmission helps improve fuel economy. BorgWarner’s innovative new clutch module features two clutch packs combined into one space-saving housing. To meet the specifications for the transmission’s compact layout, the clutch module shares splines with another clutch to reduce space. Nested pistons made from low-weight aluminum also reduce the overall length and weight of the module. In addition, multi-segment wet friction plates employ full-depth intricate groove designs to improve shift feel and reduce drag 20% compared with conventional multi-segment plates.
