E-Moves From Dana
By Ian Cameron31 January 2019
Dana is introducing two new electric drivetrain solutions for off-highway vehicles, including the Spicer Electrified e-Axle and e-Gearbox. These technologies enable electrified propulsion within established vehicle architectures by leveraging the company’s portfolio of motors, inverters, and controls, said Dana.
The Spicer Electrified e-Axle combines Dana’s heavy axle design with a high-efficiency TM4 SUMO HP motor/generator and inverter combination for medium-sized mining trucks, medium-sized load haul dumpers, and large lift trucks.
Supplying 139 kW (189 horsepower) of continuous power and 193 kW (262 horsepower) at peak power, the TM4 motor/generator and inverter are joined at the center housing of the axle to provide needed torque and efficiency within the space typically allotted for an internal-combustion engine and transmission, the company said.
The Spicer Electrified e-Gearbox features a compact design that manages high input speeds and accommodates the installation of an electric motor. It offers an engineered interface for connecting cost-effective motors used in electrification with conventional Spicer hydrostatic transmissions.
Its plug-and-play design combines Dana-supplied TM4 and SME electric motors with Spicer hydrostatic transmissions for small- and medium-sized wheel loaders up to 10 tonnes (11 tons) and telehandlers with lift capacities up to 6.8 tonnes (15,000 lbs.). The e-Gearbox is will be available for customer testing in the second half of 2019, said Dana.
