2013-12-11 13:00:41 - Oerlikon Graziano reveals details of innovative new transmission at CTI Symposium Berlin
Rivoli, Italy 11 December 2013 – High-performance transmission specialist Oerlikon Graziano, brand of Oerlikon Drive Systems Segment, unveiled details of its new hybrid, six-speed AMT at the CTI Symposium Berlin. The OGeco transmission will be more cost effective, lighter and efficient than DCT alternatives, and utilise torque infill to provide seamless shift benefits.
“The OGeco concept has been designed to provide torque infill from an electric motor during gear changes, providing the refinement of a DCT,” says Roberto Gay, Oerlikon Graziano Head of Automotive Transmission Design, who is presented a technical paper alongside Marco Fracchia, Technical Specialist for VOCIS Ltd, which is responsible for the OGeco control unit. “Increased low speed comfort does not compromise the rapid shift time and
responsiveness during spirited driving, thanks to a two-speed electric motor transmission solution enabled by a twin-shaft AMT layout. Smooth shifting at low to medium vehicle performance matches current DCT expectations, and the transition to high-performance is enabled by significant torque infill to reduce shift shock.
“The hybrid unit is designed for high performance vehicles with transaxle transmission configuration, suitable for front- and rear-wheel drive application, and we believe the OGeco concept is central to the continued evolution of performance transmissions,” continues Gay. “This technology is able to provide an innovative breakthrough for the automotive industry as manufacturers seek reduced fuel consumption and improved CO2 emissions.”
The OGeco unit will be ready for trial in a front-engined, rear-wheel drive high-performance demonstrator vehicle in early 2014. The production vehicle has been equipped with an OGeco prototype transmission, electric motor and ancillaries by Vocis, and demonstrates the packaging benefits by fitting into the space previously taken by a seven-speed DCT. Reduced weight, improved efficiency and fuel economy are further benefits of the transmission.
Depending on customer requirements, OGeco can support different drivetrain layouts to provide a range extender drive for plug-in hybrid vehicles, torque infill, electric boost and KERS performance benefits thanks to the unit’s 120kW, 200Nm output. Regeneration of the electric motor is also possible from the car’s internal combustion engine thanks to an innovative and flexible management system.
