摘要： A fifth wheel suspension assembly for damping movement between a towed vehicle and a towing vehicle is provided. The suspension assembly includes two rods on which a fifth wheel base is mounted. The fifth wheel base moves along the two rods in a direction of the longitudinal axis of the towing vehicle. The fifth wheel base defines two bores through which the rods extend. These bores also define fluid chambers disposed about the rods. Pistons are disposed about the rods within the fluid chambers and serve to dampen oscillatory movements of the towed vehicle relative to the towing vehicle. Springs disposed about the rods on either side of the base further dampen pitch motions imparted to the towing vehicle by the towed vehicle.
