Enhancement of trucking facilities for effective work under conditions of lack of roads, in a wide range of difficult road conditions and on highways

Function
Reliable and effective freight handling under conditions of lack of roads, in a wide range of difficult road conditions and on highways by one mean of transport.
Advantages
  • Pluggable semitrailer drive;
  • Index of adhesion weight 1, which provides high vehicle flotation;
  • High flotation, which makes possible heavy goods transference under difficult road conditions;
  • Recallability of drive shafts rotation, when drive of semitrailer’s wheels is unpowered, which reduces load upon transmission and provides fuel economy;
  • Reduction of dynamic loads in active semitrailer’s drive, when in motion with unpowered semitrailer’s wheels, which decrease working time of transmission;
  • Decrease of road train transmission efficiency, which leads to fuel economy;
  • Highlevelofmaintainability. As driving axle of semitrailer standard driving axle of tractive vehicle is used;
  • High reliability of semitrailer’s mechanical drive;
  • Adjustability of turning torque passing from engine to drive wheels of semitrailer, depending on road conditions of train’s movement, which allows to increase vehicle flotation .
Development stage
      Draft design, technical and economic assessment.
