  1. 1. Dynamic Torque Modeling of a Wet Lamella Clutch Pack

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Jacob Wallersköld; Johan Appelros; [2021]
    Nyckelord :wet lamella clutch; friction modeling; torque modeling; torque accuracy; force measurements; system identification; grey-box modeling; Technology and Engineering;

    Sammanfattning : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. LÄS MER

  3. 2. Modelling and filtering of wheel speed signals to determine driveline behavior in an all-wheel drive vehicle

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Jakob Wilson; David Bäcklund; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In vehicles there are many issues involving the safety and performance. The safety issues are often regulated by governments, whereas the performance by the customer. One solution to both these issues is to take use of an all-wheel drive system, where a coupling engages and disengages driving axles when needed. LÄS MER

  4. 3. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Balaji Srinivasan Venkatesan; [2020]
    Nyckelord :1-D simulation; System simulation; ROMAX Energy; LMS AMESim; Power loss; Hypoid gear; Power Transfer Unit; Efficiency and Drag Loss Tests; 1-D simulering; systemsimulering; ROMAX Energy; LMS AMESim; effektförlust; hypoidväxel; kraftöverföringsenhet; effektivitet och dragförlusttester;

    Sammanfattning : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.

  5. 4. Dynamic Analysis of an Automotive Power Transfer unit : Towards prediction of TE and housing vibrations

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Nikhil Maharshi Kosaraju; [2019]
    Nyckelord :Power transfer unit PTU ; Multi-Body Simulation MBS ; Transmission Error; Gear NoiseVibration; Modal Analysis; Vinkelväxlen PTU ; Multi-Body Simulering MBS ; transmissionsfel TE ; Växelljud och vibrationer; Modal analys;

    Sammanfattning : This work describes the use of Multi-Body Simulation (MBS) to create a virtual prototype of a geared drive called Power transfer unit (PTU). PTU is a subsystem of the all-wheel drive driveline responsible for transfer of power between front and rear axles in an Automobile. LÄS MER

  7. 5. Evaluations of Vibrations in a Wet Clutch

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

    Författare :David Sandlund; Oskar Wintercorn; [2019]
    Nyckelord :Haldex; BorgWarner; Friction; Vibrations; Wet Clutch; Tribology; 4wd; four wheel drive; all wheel drive; awd;

    Sammanfattning : BorgWarner Powerdrive Systems is constantly developing the performance of wet clutches used in passenger car all-wheel drive systems. The Haldex limited slip coupling, LSC, is the trade name of the all-wheel drive system sold and developed by BorgWarner Powerdrive Systems. LÄS MER
