Abstract
Stemming from predictions made for transmission adoption and sub-system volumes up to 2020 for the EU market, a concept study and recommendations are presented for a 6-speed 200Nm powershift transmission covering the following:
- Specific new features for low cost and high efficiency applied to a DCT,
- Novel, direct acting electromagnetic linear actuators for modulation of clutches and shift rails,
- Mechanical multiplexing to allow control of both clutches and shift rails using two linear actuators only.
