BorgWarner has announced that it has extended its cooperation with HYCET Transmission Technology by supplying supply triple-clutch P2 drive module and hydraulic control unit to Great Wall's Haval and WEY brands.
The company supports the world's first 9-speed P2 9HDCT hybrid transmission for HYCET 'I-Era 2.0' powertrain that features nine gears and a parking lock function for greater vehicle efficiency and performance.
The triple-clutch P2 hybrid drive module and hydraulic control unit will have mass-produced by the end of January 2022.
BorgWarner's on-axis P2 drive module, which matches HYCET, delivers cost-effective hybridisation through its compatibility with existing vehicle platforms, with the electric motor placed directly between the internal combustion engine and the transmission.
The P2 solution has a compact axial and improved performance and can integrate up to three clutches, including a disconnecting clutch, the company said. In addition, it allows the system to decouple from the engine for pure electric driving, enabling the vehicle always to provide adequate power performance when the engine is not working or in inefficient areas.
The control unit for HYCET adopts a next-generation low-leakage design to improve the hydraulic system's efficiency further. In addition, the latest solenoid valve is also designed for optimised clutch and shifting characteristics, resulting in better system efficiency and performance.
The on-axis P2 drive module can be installed directly into the drive shaft for easy integration. The compact design with up to three nested clutches minimises overall length, enabling OEMs to integrate it with various engines and vehicle platforms, including high voltage PHEV, high voltage HEV and 48V systems. The triple-clutch P2 module integrates the disconnecting clutch, the drive motor and the cooling system and features a high-performance, low-noise stator delivering 95% peak efficiency.
The S-wind wire-forming process helps the motor produce high power and torque densities in an extremely compact package.
Dr Volker Weng, President & General Manager, BorgWarner DriveTrain Systems, said, 'Our customised triple-clutch P2 module can meet the requirements for HYCET's 9-speed 9HDCT hybrid powertrain and is especially suitable for P2 hybrids that are expected to become the mainstream of hybrid architectures.'
