Oerlikon Graziano, a brand of Oerlikon Drive Systems Segment, presented a selection of its most recent high technology transmissions and drivelines at the CTI Symposium in Suzhou. Technical highlights included 4SED, the company´s 4-speed twin-motor seamless shift electric transmission and the AVTR, the new 2-speed Automated Manual Transmission (AMT) full electric for AWD city cars or pure electric vehicles (EVs). The 4SED uses two traction motors in a compact powertrain which provides four speeds to allow running closer to peak efficiency - approximately 90 per cent. The result is an overall efficiency improvement of up to 15 per cent, which translates into increased range or improved performance for the vehicle. The transmission´s unique configuration uses two input shafts, each driven by its own electric motor.
