摘要

Improvements in coupling devices for semi-supported trailers that allow the tilting of the same, as a whole around the rear axle carrying these devices between the tractor and the semi-trailer at least two bars in the same vertical plane, one higher and compressed and lower and lower, being characterized because the lower bar stretched of the aforementioned coupling directly links the rear of the tractor to the trailer chassis, while the upper bar compressed is articulated, on the one hand on the tractor and, on the other hand on an arrow that can swing forward in relation to the chassis of said trailer.
