ABSTRACT:
A combination articulated vehicle damping system for absorbing the kinetic energy of the trail vehicle during a collision. Affixed to the trail vehicle is a damping material retainers that holds a damping material. The back of the damping material retainer engages the rear end of the damping material. A slider frame is slidably mounted in the damping material retainer and engages the forward end of the damping material. A shearable fastener prevents the slider frame from moving relative to the damping material retainer until subjected to a predetermined force. Secured to the slider frame is the connector for coupling the lead vehicle to the trail vehicle. Once the combination articulated vehicle is subjected to a predetermined force, the shearable fastener breaks allowing the slider frame to move and thereby deform the damping material. The deformation of the damping material absorbs the kinetic energy of the trail vehicle.
