1. Continuously Variable Split-Power Transmissions with Several Modes
Sammanfattning : A continuously variable transmission (CVT) of split-power design consists of a variator and an arrangement of planetary gears. A black box model describing such transmissions is presented. The model can be used for synthesis as well as loss-free analysis of split-power CVT concepts in general. LÄS MER
2. Modelling of continuously variable split-power transmissions with several modes
Sammanfattning : .... LÄS MER
3. Driving technology and development : Usability studies of gear shifters with variations in pattern, stability and design
Sammanfattning : Over the last few decades, the development of technology used in cars has moved forward at a very intensive pace. The focus has started to shift from the technology to the human as a user. LÄS MER
4. Gear engagement control for transmissions in hybrid electric vehicles
Sammanfattning : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. LÄS MER
5. On synchronization of heavy truck transmissions
Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. LÄS MER
