Dana expands electrification portfolio

Dana has expanded its Spicer Electrified e-Powertrain offerings to include a family of e-Transmissions for a variety of medium-duty electric-vehicle applications.

Spicer Electrified Zero-6 e-Transmissions are said to optimise operating range and vehicle performance for applications suited to a central drive e-Propulsion system with a conventional axle and driveshaft layout.

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 maximise shift smoothness and efficiency;
  • An optimised 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 e-Transmission series will be available in two models, the eS4700t (offering 4,700Nm of output torque) and the eS7900t (offering 7,900 Nm of output torque). The Zero-6 currently holds six patents for advanced design, including a shifting method and arrangement, exclusive lubrication methods, and a design for manufacturability. The new e-Transmission accommodates a range of medium-duty applications, such as straight trucks, walk-in vans, refuse trucks, utility trucks and platform trucks.
