The invention relates to trailer (1) for towing after a towing after a towing vehicle, said trailer (1) comprising a frame (3) configured for carrying a load and having a front end with a coupling (5) configured for connecting the trailer (1) to the towing vehicle and allowing that the trailer (1) and the towing vehicle are able to assume mutually angular positions during turning about a turning point O; and a rear end. The trailer also has a separate wheel frame (8) that is connected to the frame (3) by means (10) that allow a relative turning of the frame in relation to the wheel frame (8) during turning of the trailer about the turning point, said wheel frame (8) comprising oppositely arranged wheels (4) that support the trailer (1) during the towing and that are arranged at a distance from each other close to a respective longitudinally extending side of the frame (3); and actuator means (15) for producing said relative turning of the frame (3). The invention is characterized in that the connecting means (10) also allow a controlled transversal movement of the frame (3) in a direction towards or away from said turning point (O) simultaneously with said relative turning of the frame (3); and that the trailer (1) comprises actuator means (15) for producing said transversal movement of the frame (3).
L'invention concerne une remorque (1) pour véhicule tractant une remorque, qui comprend un châssis (3) capable de supporter une charge et comportant une extrémité avant à organe de couplage (5) pour le couplage de la remorque (1) au véhicule tracteur, permettant différentes positions angulaires mutuelles inhérentes à la conduite d'un virage autour d'un point de virage O. La remorque comprend aussi une extrémité arrière. Par ailleurs, elle comporte un cadre pour roues (8) relié au châssis (3) au moyen d'un organe de connexion (10) permettant au châssis d'accomplir une rotation relative par rapport au cadre pour roues (8) durant le virage de la remorque autour du point de virage. Le cadre pour roues (8) comprend des roues opposées (4) qui soutiennent la remorque (1) lorsque celle-ci est tractée et qui sont espacées mutuellement en étant situées à proximité d'un côté longitudinal du châssis. Enfin, la remorque comporte un actionneur (15) qui engage la rotation relative du châssis (3). L'organe de connexion (10) permet un mouvement transversal contrôlé du châssis (3) dans une direction de rapprochement ou d'éloignement par rapport au point de virage (O), simultanément avec la rotation relative du châssis (3). Enfin, l'actionneur (15) de la remorque (1) permet d'engager le mouvement transversal du châssis (3).
