  1. 1. Transient vibrations from dry clutch operation in heavy-duty truck powertrains : Modelling, simulation and validation

    Författare :Jakob Sjöstrand; Leif Kari; Ines Lopez Arteaga; Per Erik Austrell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dry clutch system; Engagement; Disengagement; Dry-friction; LuGre friction model; Heavy-truck powertrain; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : For internal combustion engines used in heavy-duty vehicles, increased engine efficiency and consequently reduced CO2 emissions can be obtained if the engine speed can be kept within an optimal speed range. This requires swift and frequent gear shifts where the dry friction clutch is utilized. LÄS MER

  3. 2. Dry Clutch Modeling, Estimation, and Control

    Författare :Andreas Myklebust; Lars Eriksson; Joško Deur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Increasing demands on comfort, performance, and fuel efficiency in vehicles lead to more complex transmission solutions. One such solution is the Automated Manual Transmission (AMT). It works just like an ordinary manual transmission but the clutch and the gear selection are computer controlled. LÄS MER

  4. 3. Gear Shifting with Retained Power Transfer

    Författare :Bengt J H Jacobson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The most essential property of a powershifting transmission is that power can be transferred even during a gear shift. Automatic transmissions in vehicles are a common application. The gearbox is shifted by simultaneous engaging and disengaging of clutches, connected to a gear train. LÄS MER
