Ok, so im a little different and want to try some different approaches to my trailer suspension. I thought I would throw this out for debate. Seems if I can tuck the shock up in the frame rail it should make for less chance for damage. I havnt modeled it on Solid works yet but wanted to see if it made since to the experts here. This is just a doodle not to scale or even close. There will be airbags and a detachable sway bar in the final product. Im just playing with the concept at this point.

I need your input ... Thanks in advance.:bounce2:

looks like the cantalever suspensions in the Monster trucks

Nice "out of the box" thinking. How about the space above the shock, won't you need clearance for the travel? Looks like it would might get in the way of the trailer box and/or fender?

I might have to lower the pivit point, or make it a wider frame rail? I think that I can work that out easy enough. That is the beauty of solid works. It allows you to cycle the assemblys for clearence and stress . Here are a few ideas I had for trailing arms. Since the time I drew this up Ive decided to go with a double plate for the spindel mount. That should do away with any flex, and it will also give me three good surfaces to weld on.

I see no problems with it . The only thing you'll need to look into is that the shock will work on the kind of angle. Most are made to be pretty close to a up/down mounting for the valving to work . Steering stabilizers would be good for this mounting setting though.

Good thought!!! Do they make different compression and rebound rate steering stablizers?
 
You might try either a gas charged shock like one you can charge yourself,or a steering stabilzer shock they are ment to lay horizontal.Fabtech make a gas charged steering stabilzer and so does Superlift give them a try.

I like that idea for a suspension but what about the weight.Will it be able to hold 500-1000lbs.You might need a coil over shock.

The plan is to haul a couple of bikes in this thing so it will have to haul at least 1200 to 1500 lbs of weight. Add a roof tent and it will most likley need to handle a bit more. I know guys that run bags on their rigs without coilovers and they do just fine with about that much weight on each corner. Time will tell! LOL Coil over steering stablizers??:clap: Thanks for the help.
 
Looking Good Bob!

Good call on the Horz valving question Todd!
 
:hmm:
Make it so the spindle can be bolted on like the fronts of a cruiser (ford,jeep gm etc) to be able to run large bearings and same bolt patten as the tow vehicle
 
The M151 is the Ford replacement for the military jeep. They were used in the Vietnam War. Sometimes they took the place of jeeps in war movies. Like the one John Wayne drives in "In Harm's Way" (which of course is an error).

M151 MUTT - Wikipedia, the free encyclopedia

Wikipedia has a brief MUTT writeup. The suspension I'm talking about is the M151A2, which corrected the rather squirrelly defects of the M151 and M151A1 suspensions.

Howdy! Most shocks do not know about gravity. They only know compression and extension. The valving operates on pressure from either side, but not from gravity. I have seen similar setups on open desert race trucks in the good old days. Some of them even had the shocks running side to side, between the frame rails. John

I am sure Im not blazing new ground here with this design. I am only thinking that something a little more unique might be the answer for me. And by original, I mean trailer wise.:cool: I dont want to have anybody worried about patent issues.

Howdy! What I meant was that it IS a workable system. I think it's a neat idea. By doing some geometry, you can get a shorter shock to make a lot longer travel by using an offset bellcrank. Shocks have different valving for compression versus extension, but steering stabilizers do not. Go for it! John

Thanks for the input John! I am going to press foward with this idea and see where it takes me. Thanks again for the suggestions. I have been playing with the trailing arm design abit and will post up some early designs.
