Dana Incorporated has debuted a modular, high-efficiency, flexible two-speed electrified transmission for underground mining vehicles.
The new Spicer Electrified e-Powershift transmission offers functionality of power take-off (PTO) for an electrified mining machine, and within a compact package.
The dual-motor version of the e-Powershift transmission supports continuous power outputs up to 322 horsepower (240 kW), while the single-motor configuration is engineered for 161 horsepower (120 kW) of continuous output.
It is equipped with Dana TM4 high-voltage motors from 350 to 800 volts, which serves to improve efficiency, reduce total package size and provide redundancy where needed.
The e-Powershift transmission also offers efficient shifting through a patented wet clutch and synchronizer; the turnkey solution can be configured with four-wheel-drive disconnect and a PTO that eliminates the need for an additional motor and inverter.
“Its flexible, power-dense design makes it ideal for a wide range of applications, including small- to medium-sized loaders and trucks used in underground mining, as well as construction wheel loaders, large lift trucks, and terminal tractors,” Dana senior vice president, Off-Highway Drive and Motion Systems Jeroen Decleer said.
“The highly efficient dual-motor configuration shown at MINExpo delivers the optimal tractive effort in every duty cycle without torque interruption.”
The company is aiming to make the Spicer transmission available for prototype testing by OEMs by the end of this year.
Ohio-based Dana can be found in 33 countries on six continents.
