6. A Closer Look at the “D” Connection

7. NZR Patented D-Train Hitching System View from the Top Down – The “Rigid” Connection • Tractor has just backed into the kingpin of the trailer and by nudging forward has already exposed the “B-Train” for connection to the second trailer ( a single axle trailer and an “A-Train converter dolly connection is optional) • Have ignored the landing gear for simplicity of demonstration • The tractor-facing end of the trailer bogie is equipped with a unique after-frame pocket assembly which has entrance guides on each side. The after-frame of the tractor will typically tuck inside the trailer D-Train pocket about 11 – 12 inches. This depth is managed by allowing the fifth wheel to be pushed or pulled to complete a proper connection.

26. Tractor-Trailer “GAP” The D-Train Configuration Reduces “Drag”, Which Reduces Fuel Consumption A D-Train configuration closes the tractor trailer “gap” to as little as 6 inches. Total baseline drag in crosswinds for a T-T combination approximates a CD of 0.75. Closing the “Gap” from an average of 4.5 feet to just 6 inches, results in 44% (2/4.5 - note adjustment for addition of 2 feet between lead and pup units) reduction in drag derived from these connections or CD measure reduction of .066 (44% x .15) – overall an 8.8% (.066/.75) reduction in total rig drag. At 60 mph that yields fuel savings of 4.4% (8.8%/2% see table) and the higher the speed the greater the savings Source: SAE International Aerodynamic Drag Reduction Studies, 2003

27. Tractor-Trailer “GAP” The D-Train Configuration Reduces Fuel Consumption NOTE that with integrated fairings design, it is possible to eliminate all effects of tractor-trailer gap – fairings could completely encase the head of the trailer since it is rigidly attached to the tractor Total baseline drag in crosswinds for a T-T combination approximates a CD of 0.75. Closing the “Gap” from an average of 4.5 feet to just 6 inches, results in 44% (2/4.5 - note adjustment for addition of 2 feet between lead and pup units) reduction in drag derived from these connections or CD measure reduction of .066 (44% x .15) – overall an 8.8% (.066/.75) reduction in total rig drag.

29. Ontario LCV Limits Maximum Box Length 65’ 7” Max 16’ 5” Maximum Combination Length 82’ • Ontario and the rest of the provinces limit the combined trailer length to 65’ 7 “ for B and C-Train combinations ( 60.7 feet for A-Train combinations) • In the USA it varies by state, for example, Oregon limits doubles trailer lengths to 60’ in general and 68 feet on designated highways. South Dakota, on the other hand, permits trailer combinations as long as 81.5 feet for a 2 trailer rig. • Some pertinent points for Ontario: • Trailer box lengths for the D-Train – These two units ought not be built in equal sizes (ie., each say 31.5 or 30). Doing so would not enhance their combined ability to handle more whole skids, assumed for the most part to equal 4x4 in dimension. A solution is to build one unit say 28.5 and the second unit 35. With a 2 foot allowance for “gap” that creates a combined length of 65.5. This combined capacity can load 60 skids per layer versus 52 in a 53 foot semi-trailer, a 15.4% improvement in skid loads per trip. • Optimizing to the regulated combined box length results in there being 16’ 3” feet left for a tractor unit to be hooked rigidly to the lead trailer unit. A day cab unit would require only about 9’10” to 10’. At 16’ 5” there is sufficient space to support all forms of sleepers for TL linehaul work.
