Oerlikon Graziano will display new transmission products for hybrid and electric vehicles at the upcoming VDI Wissenforum in Germany. Products displayed at VDI include the 2SED, a dual-speed seamless-shifting transaxle that can be coupled with a transversal electric motor, for front or rear full electric axle, and the electric transmission multispeed 4SED, a new compact, lightweight transmission offering increased efficiency, smooth shifting and a scalable design, making it suitable for a wide range of vehicle types.
Oerlikon Graziano will also show a new 2 Speed Automated Manual Transmission. Developed in a EU-funded research project (FP7), called AVTR (Adaptable Voltage & Trasmission Ratio), it is a full electric transmission for AWD city cars or pure Electric Vehicles.
The 2 speed AMT offers different solutions for EV market. Used singularly it provides the advantages of multispeed transmissions to pure electric vehicles, while applied as two independent axles it makes the vehicle AWD and at the same time allows seamless shifting.
In addition, the company has created a hybrid transmission for supercars to combine the advantages of AMT solutions with those of the dual-clutch technology: OGeco. The new six-speed hybrid transmission offers performance, efficiency and cost reduction, it is lighter and more compact than traditional DCTs, with “torque infill” to reduce shift shock.
