Oerlikon Graziano's 4SED, multi speed transmission
Oerlikon Graziano is still looking for OEMs who would be willing to use something more than a single-speed transmission in electric cars, but besides the first batch of Tesla Roadster, nobody seems interested in multi-speed transmission for series production electric vehicles.
At the VDI Wissenforum in Germany, Oerlikon Graziano will present three models for EVs:
- the 2SED, a dual-speed seamless-shifting transaxle that can be coupled with a transversal electric motor, for front or rear full electric axle
- the electric transmission multispeed 4SED, a new compact, lightweight transmission that boasts increased efficiency, seamlessly smooth shifting and a scalable design, making it suitable for a wide range of vehicle types
- the 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
Paolo Mantelli, Head of Performance Automotive Oerlikon Graziano stated:
“Our new transmission concepts will advance the development of electric vehicles, they are the most suitable for a modern full electric or even hybrid vehicle, allowing the best sizing of the electric motor and usage of batteries’ power."
Oerlikon Graziano made us laugh a little bit because on the right side of its press release it asked us whether we knew that their single-speed gearbox was used in THINK City, "a mass-production urban electric vehicle". Well, it's 2014 and most of our readers already forgot THINK, a company which went bankrupt together with battery supplier Ener1/EnerDel. Maybe Oerlikon Graziano should find a better example?
