Eaton announce gearbox for electric trucks
THE rise of electric trucks continue unabated in the U.S.
After Mack and BYD last month announced their plan to use electric-turbine and full-electric trucks and the Nikola 1 truck inspired over 7 000 depositors to part with $1 500 (R21 800) each, clutch maker Eaton last week announced will make a gearbox specifically for electric trucks.
Eaton said it is involved in a production programme with Pi Innovo and UQM Technologies to make a twospeed gear transmission, which will link to UQM’s PowerPhase HD220/ HD250 motor and inverter system to create a full electric drivetrain system called the “UQM PowerPhaseDT”.
Eaton stated its two-speed transmission will provide a greater speed and torque range from what would normally be possible in a direct drive system, allowing a smaller electric motor to drive large vehicles.
The smaller drivetrain will also allow for better packaging, efficiency, greater payload capacity and lower cost when compared with direct drive or single speed drivetrain strategies.
The trio plan to start production early next year.
Future truck transmissions will become as small as this, from the half-a-ton casings of today (below).
