  1. 1. Optimal Predictive Control of Wheel Loader Transmissions

    Författare :Tomas Nilsson; Jan Åslund; Lars Nielsen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The transmissions of present heavy wheel loaders are in general based on torque converters. The characteristics of this component suits these machines, especially in that it enables thrust from zero vehicle speed without risk of stalling the engine, without active control. LÄS MER

  3. 2. Automation of Wheel-Loaders

    Författare :Siddharth Dadhich; Ulf Bodin; Fredrik Sandin; Ulf Andersson; Jerker Delsing; Juha Röning; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Automation and tele-remote operation of mobile earth moving machines is desired for safety and productivity reasons. With tele-operation and automation, operators can avoid harsh ergonomic conditions and hazardous environments with poor air quality, and the productivity can in principle be improved by saving the time required to commute to and from work areas.

  4. 3. Suspension design for off-road construction machines

    Författare :Adam Rehnberg; Lars Drugge; Annika Stensson Trigell; David Crolla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction machine; engineering vehicle; earth mover; wheel loader; vehicle dynamics; vehicle engineering; whole body vibrations; off-road vehicle; anläggningsmaskin; entreprenadmaskin; hjullastare; fordonsdynamik; fordonsteknik; helkroppsvibrationer; terrängfordon; Vehicle engineering; Farkostteknik;

    Sammanfattning : Construction machines, also referred to as engineering vehicles or earth movers, are used in a variety of tasks related to infrastructure development and material handling. While modern construction machines represent a high level of sophistication in several areas, their suspension systems are generally rudimentary or even nonexistent. LÄS MER

  5. 4. Optimal Engine Operation in a Multi-Mode CVT Wheel Loader

    Författare :Tomas Nilsson; Jan Åslund; Lars Nielsen; Anders Fröberg; Lars Johanneson Mårdh; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Throughout the vehicular industry there is a drive for increased fuel efficiency. This is the case also for heavy equipment like wheel loaders. The operation of such machines is characterized by its highly transient nature, the episodes of high tractive effort at low speed and that power is used by both the transmission and the working hydraulics.

  7. 5. Vehicle dynamic analysis of wheel loaders with suspended axles

    Författare :Adam Rehnberg; Annika Stensson Trigell; Lars Drugge; Peter Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hjullastare; arbetsmaskin; fordonsdynamik; fordonsteknik; Vehicle engineering; Farkostteknik;

    Sammanfattning : The wheel loader is a type of engineering vehicle used primarily to move crude material over shorter distances. As the vehicle is designed without wheel suspension, wheel loader drivers are exposed to high levels of whole body vibration which influences ride comfort negatively. LÄS MER
