  1. 1. 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

  3. 3. On the Mechanisms behind the Tribological Performance of Stellites

    Författare :Daniel H. E. Persson; Sture Hogmark; Staffan Jacobson; Mikael Olsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Stellite; Co-based; phase transformation; fcc; hcp; texture; alignment; low-friction; laser cladding; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This thesis reveals the tribological mechanisms behind the intrinsic low friction potential of the Co-based family of alloys called Stellites. Although being an established and important group of materials, a satisfactory explanation to why they exhibit low-friction properties under severe sliding conditions has not previously been found in the literature.
