A TRAILER FOR TOWING AFTER A TOWING VEHICLE, A SYSTEM COMPRISING A TRAILER AND A TOWING VEHICLE, AND A METHOD OF STEERING A TRAILER AROUND A TURNING POINT

摘要

The invention relates to trailer (1) for towing after a towing after a towin g 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 th e 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 whe el 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) durin g 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 mean s (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 sa id 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).
