BorgWarner says the first dual-clutch transmission (DCT) for Class 6 and 7 trucks in North America is powered by its DualTronic clutch module.
BorgWarner’s fuel-efficient technology helps Eaton’s new Procision 7-speed DCT improve fuel economy 8 to 10 percent compared with similarly equipped vehicles with torque converter automatic transmissions, the company says.
Designed to deliver the fuel efficiency of a manual gearbox combined with the convenience and smooth shifting of a fully automatic transmission, BorgWarner’s DualTronic clutch module features advanced high-energy wet friction materials for responsive shifting, dynamic performance and robust durability.
“Proven in the passenger car market, BorgWarner’s DualTronic clutch modules will now provide improved fuel economy and performance for the commercial vehicle market. These are important benefits for businesses that rely on trucks to deliver goods every day,” says Robin Kendrick, president and general manager, BorgWarner Transmission Systems. “We are pleased to contribute BorgWarner’s extensive expertise in dual-clutch technology and high-energy wet friction materials for Eaton’s first DCT for commercial trucks.”
BorgWarner worked closely with Eaton to jointly develop DCT technology specifically for commercial vehicles. This product features two wet clutches that engage the odd and even gears respectively, allowing shifts within fractions of a second with no perceived interruption of powerflow, the company says.
Engineered for the higher mileage and durability requirements of commercial vehicles, BorgWarner’s DualTronic clutch modules also feature hardened materials to reduce wear and an advanced design to meet Eaton’s tough weight and performance targets. High-energy wet friction materials with a specially developed groove design minimize spin losses and provide improved heat resistance, high torque capacity and reliable operation over the transmission’s lifetime, the company says.
