ABSTRACT:
A self-moving car (1) for the moving of trailer machines (100), comprising a main chassis (2); wheels (4′, 4″) engaged with the chassis (2); a generating and feeding unit (5) and movable means (20) for coupling the car (1) with a trailer machine (100) to be towed; the car (1) further comprising an apparatus (80) for the articulated connection to the chassis (2) of the movable coupling means (20), comprising a pin (8) hinged to the chassis (2), the pin (8) having a first bottom end (9) connecting to actuating means (11) for the bilateral rotation (beta) of the pin (8), so that to the rotation of the pin (8) there corresponds a proportional variation of tilt of said movable coupling means (20) with respect to the ground plane; and a second top end (10) for the rotating coupling to the movable coupling means (20); the car (1) further comprising independent driving means, so that to a differential rotation of the wheels (4′, 4″) there corresponds a proportional rotation (&ggr;) of the movable coupling means (20) relative to the chassis (2), about a substantially longitudinal axis (C-C) of the pin (8).
