Product Features

All of IEdrives heavy duty transmissions for electric and hybrid electric trucks and buses have the same following features.

• Modular design, available in 2, 3, 4 and 5 speed configurations
• Planetary gear drive sets offering:
• Very high power transmission efficiency - greater than 95% at all operating points
  • Regenerative braking capability at all speeds
  • 10,000 rpm input speed
  • 1800 lbf-ft {2440 N-m} input torque rating
  • Very compact, light weight design
• Very heavy duty input and output shafts
  • standard 1.5 inch diameter, fully heated
• Standardized driveshaft connection
  
  • Compact flange yoke adaptor for 1610, 1550 or 1480 U-joint
  • Robust 8 bolt attachment
  • All other U-joints can be accommodated
• All parasitic losses are minimized by:
  • No pressurized lubrication required, (1-2 kW losses avoided)
  • No torque converter required, (3-15kW losses avoided)
  • Direct hard coupling of transmission to motor
• Highly compact installation and mounting to traction motor
  • All transmissions offer a female splined input ring
  • All can be made to accept most motor output splined shafts directly – 1.5” diameter or smaller<
  • No motor to transmission shaft coupler is required
  • Mounting plate can be less than 1 inch (25 mm) for most motors depending upon motor shaft dimensions
• Gear selection is electrically controlled
• Choice of three different shifters; all shifters offer very low energy consumption
