Transmission specialist Oerlikon Graziano SpA presented more detail on its prototype eDCT dual-clutch-type transmission for electric vehicles (earlier post ) at the first CTI Symposium China, in Shanghai. The clutch-less and synchronizer-less eDCT uses the principles of dual clutch transmissions (DCTs) to provide seamless shifting and up to a 15% improvement in vehicle efficiency. The four-speed transmission uses two input shafts, each driven by its own electric motor—i.e., the concept is similar to that of a DCT but uses two motors in place of the twin clutches. One motor drives a shaft that carries first and third gears, the other drives a shaft carrying second and fourth. This allows pre-selection of the next gear before...
