Dana recently announced an expansion of its Spicer Electrified e-Powertrain offerings to include an offering of e-Transmissions for a variety of medium-duty EV applications. The technology will launch on a global electric vehicle platform in early 2024, Dana says.
Spicer Electrified Zero-6 e-Transmissions are suited ideally for central drive e-Propulsion system with a conventional axle and driveshaft layout. The powertrain is said to accommodate a diverse range of medium-duty applications, such as straight trucks, walk-in vans, refuse trucks, utility trucks, platform trucks, and more.
Dana said that the new e-Transmissions have been engineered to provide the highest level of efficiency and performance with maximum startability, gradeability, and road speed.
The company says that other features include:
- Dana motor and integrated inverter system, with silicon carbide technology and MOSFET power modules, providing simplified installation in the vehicle through the elimination of high-voltage phase cables;
- An electromechanical actuation system, with patented Dana Graziano clutch design, to maximize shift efficiency;
- A three-speed system with Ravigneaux gearing designed to seamlessly integrate Dana motor technology, offering maximum power density and productivity without compromise across a wide range of vehicles; and
- Dana OpenECU platform, leveraged across all Dana e-Propulsion technologies, to deliver control software, functional safety readiness up to ASIL C, and compliance with the latest vehicle cybersecurity engineering standard ISO/SAE 21434 and the UNR 155/156 regulations.
Accommodating a gross vehicle weight rating up to 59,500 lbs., the Zero-6 eTransmission series will be available in two models, the eS4700t and the eS7900t, offering 4,700 and 7,900 Nm of output torque, the company notes.
