    Abstract : 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. READ MORE

  5. 13. A Comparative Investigation of Gear Performance BetweenWrought and Sintered Powder Metallurgical Steel : Utilizing In-situ Surface Profile Measurements to Investigate theInitiation and Evolution of Micropitting and Pitting Damage

    Author : Edwin Bergstedt; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear testing; Micropitting; Pitting; Efficiency; Surface transformation; Kugghjulstestning; Micropitting; Pitting; Effektivitetsmätning; Yttransformationer; Machine Design; Maskinkonstruktion;

    Abstract : Vehicle electrification is a strong trend that introduces new challenges, such as increased input speed of the transmission and increased power density. Alsothe noise emittance of the gearbox is of increasing importance, as the sound of the gearbox is no longer masked by the internal combustion engine. READ MORE

  6. 14. Influence of running-in on gear efficiency

    Author : Sören Sjöberg; Ulf Olofsson; Björklund Stefan; Lehtovaara Arto; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; gear manufacturing; running-in; efficiency; friction; surface topography; Machine Design; Maskinkonstruktion;

    Abstract : The general trend in gear industry is an increased focus on gear transmission efficiency. This thesis focuses on the understanding of how different gear manufacturing methods – particularly the contribution of the running-in process – affect the surface characteristics and friction response, with the purpose of increasing gearbox efficiency.

  7. 15. Gear Shifting with Retained Power Transfer

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

    Abstract : 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. READ MORE
