Dana Inc. announced a new line of electric transmissions from its Spicer Electrified line, for a wide variety of electric trucks and vans. Dana says the new line of Zero-6 transmissions will launch in early 2024.
Accommodating a gross vehicle weight rating up to 59,500 lbs., 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.
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 highlighted by the company 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 Dana’s Graziano clutch design, to maximize shift smoothness and efficiency;
- An optimized three-speed system with Ravigneaux gearing designed to integrate Dana motor technology; and
- Dana OpenECU platform, which offers 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.
