1. An articulated vehicle having a plurality of modules interconnected with one another in an articulated manner, said articulated vehicle comprising:

  • a leading module (1) having a leading end, a trailing end and a front steering set of wheels (12), a rear module (3) having a leading end, a trailing end and a rear set of follower wheels (13), and at least one intermediate module (2) having a leading end and a trailing end and being located between said leading module (11) and said rear module (3);

    wherein each pair of two adjacent modules is interconnected by a composite articulated connection (4,

         5); and

    each said composite articulated connection (4,

         5) comprises;

    at least one movable articulation support (6,

         7) which is supported by an axle (10,

         11), said movable articulation support is connected to a leading one of said pair of adjacent modules by a front connection articulation (14) and a trailing one of said pair of adjacent modules by a rear connection articulation (16) having three degrees of freedom, said front connection articulation (14) is connected at a median position to the trailing end of said leading one of said pair of adjacent modules, and said rear connection articulation (16) is connected at a median position to the leading end of said trailing one of said pair of adjacent modules;

    an oblique articulated connection (8,

         9) extends obliquely with respect to a longitudinal axis of said articulated vehicle when said pair of adjacent modules are aligned with one another, said oblique articulated connection (8,

         9) has a leading end and a trailing end, said oblique articulated connection leading end is connected at position that is offset from the median position of the trailing end of said leading one of said pair of adjacent modules, and said oblique articulated connection trailing end is connected to the leading end of said trailing one of said pair of adjacent modules at a position diagonal opposite offset with respect to said connected position of said oblique articulated connection leading end; and

    a double articulated connection (15) is formed by a connection between said rear connection articulation (16) and a top articulation (17) which has limited movement, and said front connection articulation (14) and said top articulation (17) are interconnected with one another by structure of said moveable articulation support (6,

         7).
