Dana Incorporated recently announced an expansion of its Spicer Electrified e-Powertrain offerings to include a family of e-Transmissions for a wide variety of medium-duty electric-vehicle applications.
Dana says the technology will launch on a global electric-vehicle platform in early 2024.
Spicer Electrified Zero-6 e-Transmissions optimize operating range and vehicle performance for applications ideally suited to a central-drive e-Propulsion system with a conventional axle and driveshaft layout.
The company states that the new e-Transmissions have been engineered to provide the highest level of efficiency and performance with maximum startability, gradeability and road speed.
Other key features include:
- Dana high-efficiency motor and integrated inverter system, with silicon carbide technology and MOSFET power modules, providing peak performance and 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 smoothness and efficiency
- An optimized 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
- Dana OpenECU platform, leveraged across all Dana e-Propulsion technologies, to deliver next-generation 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
“Dana’s commitment to providing sustainable solutions for clean transportation is reinforced by the development of Zero-6 e-Transmissions,” said Ryan Laskey, senior vice president of Dana Commercial Vehicle Drive and Motion Systems. “This new technology is a significant step towards further electrifying the medium-duty commercial vehicle market, and we are proud to be at the forefront of this revolution.”
Accommodating a gross vehicle weight rating up to 59,500 pounds, the Zero-6 e-Transmission series will be available in two models: the eS4700t and the eS7900t, offering 4,700 and 7,900 Nm of output torque, respectively.
The company notes that the Zero-6 currently holds six patents for advanced design, including a unique shifting method and arrangement, exclusive lubrication methods, and a design for manufacturability. The new e-Transmission accommodates a diverse range of medium-duty applications, such as straight trucks, walk-in vans, refuse trucks, utility trucks, platform trucks, and more, the company adds.
