Fairings Over Tractor's Tandem Save Fuel for Tanker Fleet

FlowBelow Aero devices control air flow and boost economy by 3%, says Indian River Transport.

Wheel covers and fairings between and behind the tractor tandem's wheels reduce turbulance and save fuel.

September 9, 2015

Stainless steel tanker trailers look smooth enough to easily slip through the air, but they have characteristics that cause drag. One fleet has turned to an aero system for the tractor tandems to help smooth the air flow over the trailer.

Replacing Rivets with Adhesives Yields Smoother Sides That Could Save Fuel

Computational fluid analysis interpreted air flow over the trailer panels’ surfaces, finding some drag produced by rivet heads.

As trailer aerodynamics improve, the small amount caused by air flow over sidewall surfaces will become more important. Art via Lord Corp.

August 26, 2015

Lord Corp., which makes bonding adhesives, has done research that indicates eliminating rivets from a trailer’s walls might cut aerodynamic drag by about 1%.

Using Archimedes’ Lever Principle to Help Propel a Tractor-Trailer

Multiplying the tractor's pulling force could reduce required input and save 80% in fuel, this concept's inventor believes.

1. Floating kingpin  2. Linkage arm  3. Carrier bearing assembly  4. Front and rear levers  5. Trailer chassis 6. Tire-wheel assembly  7. Landing gear  8. Suspension  9. Axle  10. Input pivot (top of lever) 11. Fulcrum pivot at axle12. Output pivot at bracket mount

September 19, 2014

Archimedes, the scholar and mathematician of antiquity, was quoted as saying, “Give me a place to stand and a large enough lever, and I will move the earth.” That’s debatable, but some pretty big and heavy things can be nudged into motion with a lever – and trailers are among them, says an inventor in Ohio. Tom Berg has the story in his Trailer Talk blog.

Integrated Approach Tractor-Trailer Saves Fuel in KW's T680 Advantage Package

The Utility side skirts reduce the amount of wind that gets under the trailer, causing drag, and the TrailerTail reduces drag at the trailer's rear.

March 22, 2013

Kenworth designers have turned to the trailer part of their T680 Advantage rig, integrating the smoothly styled tractor's aerodynamics into the lines of a 53-foot Utility van. The tractor has mechanical and electrical equipment meant to save fuel, but reducing air drag across the entire vehicle is almost as important, they said.
