  1. 1. Continuously Variable Split-Power Transmissions with Several Modes

    Författare :Per Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuously variable transmission; variator; speed ratio range; ratio coverage; traction drive; mode shift; CVT; planetary gear; power split; IVT; infinitely variable transmission; epicyclic gear train; hydrostatic variator;

    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

  7. 5. Optimal Engine Operation in a Multi-Mode CVT Wheel Loader

    Författare :Tomas Nilsson; Jan Åslund; Lars Nielsen; Anders Fröberg; Lars Johanneson Mårdh; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Throughout the vehicular industry there is a drive for increased fuel efficiency. This is the case also for heavy equipment like wheel loaders. The operation of such machines is characterized by its highly transient nature, the episodes of high tractive effort at low speed and that power is used by both the transmission and the working hydraulics.
