CVTs to aid ‘greener’ motorsport

Toroidal traction drive specialist Torotrak and vehicle transmission design and manufacturing company Xtrac announced on June 5th 2007 that they have entered into a licence agreement to enable Xtrac to develop continuously variable transmissions for use in the new kinetic energy recovery systems (KERS) proposed for Formula One for 2009

. FIA president Max Mosley announced back in June 2006, that,”What we have in mind is this: that every car can be fitted with equipment, which must weigh no more than 20 kilos and will store energy when the car brakes and enable the energy to be used when the car accelerates again”. His justification was that, “We’d be doing research that relates to fuel efficiency and is thus directly relevant to road cars”. Attending a just held Motorsport Industry Association Media Trade Day at the Rockingham Motor Speedway we happened to see an example composite flywheel developed for energy storage system customers such as Pentadyne Power Corporation by Crompton Technology Group based in Banbury. Engineering Director Mike Dewhirst told us that his company had just received an order for 500 flywheel systems for use in uninterruptible power supplies. For F1, the proposed new regulations state: "5.2.3 The maximum power, in or out, of any KERS must not exceed 60kW. Energy released from the KERS may not exceed 400kJ in any one lap. Measurements will be taken at the connection to the rear wheel drive train." For more information: http://www.fia.com, http://www.ctgltd.co.ukhttp://www.torotrak.com http://www.xtrac.com
