ABSTRACT:
The invention provides for a trailer coupling which includes one or more torque elements having pads of elastic material interposed between an inner angular member and an outer angular member. The pads of the elastic material permit but resist relative vertical movement between the inner and the outer members. The inner and outer members are connected by linkages to attachment plates. The coupling can be attached to and between a draughting vehicle and a trailer to transmit traction force to the trailer. The resilient deformation of the pads of elastic material dampen relative vertical movement between the draughting vehicle and the trailer.
