<p>The invention concerns a device for damping the yawing motions between a motor road vehicle and its trailer consisting of a damping curvilinear track (4) whereon acts a friction device (17) for example a pneumatic device mounted at the end of the towbar (2), the track (4) being for example articulated to a fixed part at the rear of the truck or sufficiently flexible to absorb roll and pitch. The friction device (13) consists of friction pads (21, 22) pressed against the track (4) by an actuator (27), for example a pneumatic actuator. The intensity of the traction force generated varies according to the trailer load and/or the vehicle speed to adjust automatically the damping of the yawing motions. Said adjustment is produced by the fact that the actuator (27) is automatically controlled by the pressure of the suspensions and/or the speed of the vehicle. The invention is of particular interest to manufacturers of trailers and hitches.</p> |
