I have a question for the engineer guys on here.

The standard rear suspension has the airbag positioned between the two bogie arms so there is equal loading on both tires.

For simple calculations, lets say the weight distribution is 4000lbs on the front wheels and 8,000 on the back. So thats 4,000 on each bogie, 2,000lbs per tire. I know the bogie arms are not equal, but for simple calculations, lets say they are.

What weight does the airbag actually see?

At first thought one would say 4,000 lbs (2,000 from each tire). But looking at it further, would it only be 2,000lbs??

Lets say the airbag was fixed at one end, then it is easy to see that the airbag would have 2,000lbs to carry, but isn't there also 2,000lbs against the fixed side? So what difference is there if its fixed to the frame, or fixed against the opposite bogie.

So I'm thinking the airbag needs to only carry 1/2 the weight the bogie actually carries. The 2,000lbs from the front bogie is transfered through the bogie arm to the airbag to the other bogie arm and against the back tire.

What say yea?
