Lichfield-based Zytek is to supply 25 of its electrically operated gearshift system (EGS) for the next season of Japan’s major single-seater racing series, Formula Nippon.
EGS, which is to be fitted to all cars in the series, has already been used in all the cars in the A1GP series. It is also fitted on Zytek’s own LMP1 and LMP2 endurance racing sports cars and this season the system has been used in the three Acura teams racing in the American Le Mans Series.
According to Zytek, its EGS is lighter and more straightforward than alternative pneumatic or hydraulic systems and the all-electric operation offers engine downshift protection, reliability, simple integration and improved gearbox life. It can produce individual gearshifts in less than 40ms and up to five downshifts in less than one second.
The electric actuators are designed to move precisely, meaning there is very little wear on the gear selector mechanism and dog rings, extending gearbox life and improving reliability and shifting accuracy. The fully electric approach removes the need for a separate hydraulic or pneumatic system, reducing vehicle mass and complexity. Once fitted, Zytek claims the system is essentially maintenance-free and there is no potential for leakage of air or hydraulic fluid.
The EGS control unit includes built-in energy storage, which accumulates electrical energy from the vehicle alternator between gearshifts, so high power can be delivered rapidly for a fast shifting action.
Zytek developed all system components plus control and calibration software in-house.
