FIELD: transport engineering. ^ SUBSTANCE: invention relates to design of trailers and coupler gears. Proposed device contains arch-shaped damping pad to take action of friction device, for instance, pneumatic type, installed on end of draft pole. Damping pad is connected, for instance, by hinge joint with fixed or sufficiently resilient rear part of prime mover to kill transverse and longitudinal angular vibrations. Friction device contains friction shoes pressed to damping pad by pneumatic drive. Pressure force, thus created, changes depending on load of trailer and/or speed of prime mover automatically adapting to damping of hunting. ^ EFFECT: provision of change of operation of drive depending on pressure in suspension and/or speed of prime mover. ^ 20 cl, 6 dwg |
