Integrated Electric Drives

IEdrives automated manual transmissions (AMT) and fixed ratio gearboxes are specifically designed for direct coupling to electric motors used to power commercial vehicles.  Our high rpm capable gearing technology has over 30 years of development meeting the severe demands of NASCAR’s 600kW, 10,000 rpm continuous engines.

We also understand ‘High Torque’ through our many years of transmitting the extreme torque output from 1,500kW dragster engines to the differential.  All of our multi-speed and fixed ratio gearboxes offer very rugged and compact designs that will fit very well between frame rails.  Placing the motor/gearbox between the frame rails, close to the differential, opens up valuable real estate in the traditional engine compartment for batteries or other sensitive power electronics.

Our Severe Duty 2-speed is in serial production, delivering both 110km/h (70mph) and 14,420Nm (10,630lb-ft) of continuous torque into the driveshaft of 34,500kg (76,000lb) GVWR refuse trucks.  

Our Heavy Duty 2-speed and 1-speed gear boxes have been designed to meet the reliability and service life standards typical for heavy duty vocational trucks and buses operating in the USA.  

Our Lighter Duty 2-speed brings 200kW continuous power output and a tight, compact design for those vehicles that are 16,000lb (7,000kg) or lighter.  An option e-parking brake is available.
