Yeah, with electric propulsion and fancy voltage and frequency control of AC induction motors the motor and controller effectively act as a CVT. Series hybrids have fixed gearing for the same reason.That being said I've been on a Scottish DMU that sounded like it had a two speed transmission. I believe it was a 150 series Metro-Cammel DMU Sprinter. Before that I didn't know that people put mechanical linkages between prime movers and axles on rail vehicles since steam pistons. |
