Abstract

Hollow, pneumatic impact bodies are located on the axle supports, inboard of the wheels. They are gripped for and aft by profiled jaws with the front and rear jaws directly connected to the front and rear bumpers via horizontal shafts. The inside jaws of the front and rear axles are joined by a middle shaft to form a continuous frame from bumper to bumper. Pneumatic/hydraulic dampers are fitted to the shafts. The system absorbs large impacts and reduces the need for impact absorbing front and rear body sections. The pressure inside the impact bodies can be regulated to suit the vehicle weight and speed.
