Self-moving car for the moving of trailer machines and of static machines or the like

A self-moving car for moving static machines or the like, the self-moving car comprising:

• a main chassis;
• wheels engaged with said main chassis, the wheels having an axis of rotation;
• a generating and feeding unit, apt to deliver an energy required to produce a movement of said car on the ground, and to operate said car;
• and
• movable coupling means for coupling said car with a machine to be towed;
• said car further comprising an apparatus for an articulated connection of said movable coupling means to said main chassis, the apparatus comprising a pin hinged to said main chassis at a height of the main chassis substantially corresponding to the axis of rotation of said wheels, said pin comprising:
• a first bottom end for connecting said pin to actuating means for bilaterally rotating said pin about an axis of rotation of said pin, substantially perpendicular to the axis of rotation of said wheels, the actuating means configured so that to a rotation of said pin on the axis of rotation of the pin corresponds a proportional variation of tilt of said movable coupling means with respect to the ground plane;
• and
• a second top end for a rotating coupling of said pin to said movable coupling means;
• said car further comprising independent driving means, each of said driving means suitable for driving a respective wheel, the driving means configured so that to a differential rotation of said wheels on said driving means corresponds a proportional rotation of said movable coupling means relative to said main chassis, about a substantially longitudinal axis of the pin.
