A66 caravan smash 601

Well if it does and I dont see why it would in any major way then the cars damping will begin to help remove it! Thats a good thing. Plus if you loaded the van up a little nose heavy you wouldnt have an occilating van anyway...

It does that as well as increasing stability. My automotive dyno trailer weighed rather more than a caravan and went many countries and roads. No wear problems in many years.

A van at static or slow speed balancing behind the wheels will swing further with each swing. A van balancing exactly on the wheels will be neutral. Meaning that it has no tendency to increase its swing or decrease it. (ignoring aerodynamics for now) A van balancing in front of the wheels naturally dampens down the swing until it goes away every time its induced.

But other things effect this stability. The fact that there is a square van in crosswinds means stability is worse as speed increases. To compensate for this some extra noseweight (move c of g forwards further still) is the simplest way. When the load on the towbar becomes too high then you quite simply need a smaller lighter van or a stronger to vehicle that can take the weight it has to do for stability. Hence the truck with a strong tractor unit, trailer wheels at the rear to keep c of g in front of the rear wheels.

You didnt have to. Its just c of g effect. Theoretical. The correct balance point is one that gives you stability at your chosen top speed while not going overboard on the tow bar-rear suspension. But if it snakes you do need more noseweight! If your car towing system cannot stand that you need a different one, or keep the unstable configuration.

Go shove a few bags of cement in the rear of your van, or move the axle forwards (almost the same thing as far as the forces are concerned) and your van will snake at very low speeds and get progressively worse with each swing.

Then move them under the front seats and try again. You should be able to do 70 or more without problem. I did this when going to south of spain. No caravan but moved two 1100cc bikes to the front. Total straight line stability. Try it before you tell me I am wrong.

"LINKS" are not proof of anything. Ask a caravan or trailer designer. Or anyone with a basic understanding of the dynamics involved. Some people will never "get it" others can see this easily.

Yawn...

It will make any caravan tow straight at motorway speeds and thats what this is about.

Only adding mbutt from the rear of the van to the front. + There will be no occilation to try and damp! Its much the same as the infamous "tank slapper" that motorcycles were famous for in the 60s 70s and 80s. One day after fitting various styles and types of steering dampers for 30 years the realised that you didnt need one if you sorted out the reason for it occilating in the first place! Now even faster bikes do not come with steering dampers any longer.
