  1. 1. Prediction of life durability in friction for wet clutches of DCT gearboxes

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Lars-Johan Sandström; [2020]
    Nyckelord :wet clutch; DCT; Gearbox; Durability; Friction; Life; Dual Clutch Transmission;

    Sammanfattning : Many new cars are equipped with automatic transmissions. These gearboxes often have a dual clutch transmission (DCT) that has a built-in wet clutch. The lubricants used in these gearboxes is often very advanced because it must take care of two systems, the wet clutch and the gears. There is always a strive to make the drain intervals longer.

  3. 2. Verification of Powertrain Simulation Models Using Machine Learning Methods

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Khalid Pirgul; Jonathan Svensson; [2020]
    Nyckelord :;

    Sammanfattning : This thesis is providing an insight into the verification of a quasi-static simulation model based on the estimation of fuel consumption using machine learning methods. Traditional verification using real test data is not always available. LÄS MER

  4. 3. Drag Torque and Synchronization Modelling in a Dual Clutch Transmission

    Master-uppsats, Lunds universitet/Maskinelement

    Författare :Mikael Lund; [2018]
    Nyckelord :drag torque; synchronization; dual clutch transmission; Technology and Engineering;

    Sammanfattning : Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process.

  5. 4. CAE Tool for Evaluation of Park Lock Mechanism in a DCT Transmission

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Rasmus Andersson; [2017]
    Nyckelord :DCT; Dual clutch transmission; park lock; park lock mechanism; CAE tool; friction;

    Sammanfattning : A park lock mechanism is a device that is fitted to an automatic transmission on a vehicle. The mechanism lock up the transmission so that no rolling of the vehicle can be done when the vehicle is put in the park position. LÄS MER

  7. 5. Development and Analysis of Synchronization Process Control Algorithms in a Dual Clutch Transmission

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Andreas Gustavsson; [2009]
    Nyckelord :dct; dsg; amt; synch; synchronizer; detent; dogging; gear shift; synchronization;

    Sammanfattning : The Dual Clutch Transmission (DCT) is a relatively new kind of transmission which shows increased efficiency and comfort compared to manual transmissions. Its construction is much like two parallell manual transmissions, where the gearshifts are controlled automatically. LÄS MER
