Abstract
Improved device for automatic steering of trailer wheel axles and semi-trailer characterized by comprising a closed hydraulic circuit, provided with as many hydraulic cylinders as wheel axles provide the trailer or semi-trailer, so that each of the pistons said hydraulic cylinders are hingedly mounted to a radial arm, integral with a drive part of the wheel axles, the cylinders being double acting, with the appropriate conduits between said cylinders, and when the steering wheel of the vehicle is driven by moving the wheels of steering to one or the other side, the point of unión between the tractor and the trailer or semi-trailer, called fifth wheel, has an eccentric bolt attached to the tractor, which carries with it the corresponding piston hydraulic cylinder, at which time runs through the pipes, the liquid that drives the other double-acting hydraulic cylinders coupled to the axles rear wheels, these being displaced in the appropriate directions to follow the curvature of the road, initiated by the steering wheels, the liquid lines between the cylinders comprising nitrogen pressure accumulators, which determine a constant pressure in the circuit.
