Gap Connector Idea for CMVs
Based on Articulated Bus Design

Vicki has long had an idea for a "gap connector" to close the gap between truck and trailer similar to that which is used on articulated buses. So, as of February 17, 2015, she is putting her idea out in public.

If you look on Wikipedia for "articulated bus", you will see images of buses made with "two rigid sections linked by a pivoting joint." When you look at the photos like the one shown here, you will see that the pivoting joint of the bus is covered with a flexible device. This device reminds Vicki of a Slinky® or a bendable straw.

When the bus turns, the device flexes to accommodate the movement. Vicki has been unable to find the name of this device. However, one of our readers is likely to know it or be able to find this information.

Why can't truck manufacturers come up with a gap connector like this to use between tractors and dry van trailers?

Any device for closing the gap between truck and trailer would have to be easy to move so that truckers who do drops and hooks could easily attach it between the truck and trailer. It is possible that an extra connection device would need to be put on the fronts of trailers.

For extra challenge, those who haul refrigerated vans would need to have a way to vent their refrigeration units.

OK, Vicki's idea is now public. Now, let's see what happens in the marketplace...

(Note: An alternative spelling might be "gap connecter" -- ending with "er" instead of "or" -- although the idea for this device has no bearing on any product or service by a similar name.)

Money saving tip: It is well known that in order to increase a truck's fuel economy, air resistance or drag needs to be reduced or eliminated from around the vehicle. One of the most difficult places to reduce drag has been between the tractor and trailer.

So that articulation can occur, there is only so much shortening of the distance that can take place between the back of the tractor and the front of the trailer.

Items that create a vortex of air have been able to reduce drag in this area of the truck to a certain extent, as have trailer nose cones.

Another potential positive that could result from having a gap connector installed is less opportunity for theft of load locks from behind tractors.
