<p>The removable self-lubricating device for the coupling of semi-trailed vehicles is comprised of a self-lubricating plate (1) which takes place between the bearing plate (3) of the semi-trailed vehicle and the friction part of the saddle. According to an embodiment, said self-lubricating plate (1) is held in place against the bearing plate (3), before coupling, by pinching the base of the pivot (2) under the effect of the curvature due to the deformation under its own weight.</p> |
