Independent Suspension for a Trailer

grabcad

This is some independant suspension I have modelled for a trailer, such as an off-road camper trailer, caravan, or other such item.I have designed it to use standard off the shelf Ford Stub Axles, common in Australia (Maybe not elsewhere in the world)The design could be enhanced by Limit Straps, or other such items, or the inclusion of Airbag Suspension instead of Coil Springs.I have noted as well as of late that these types of suspension systems are becoming more popular on Military Trailers, so maybe that's another application for this file if you are designing your own Military Trailer.I designed this with the help of some documents from Huntsman Products, however the dimensions provided were essentially mounting dimensions, so I had to make the rest of it work with what I had from memory from there.I have included the Fusion file for those that wish to edit the file as well, you can see my whole workflow and make your adjustments from there.To be honest, part of my motivation for designing this was because I needed it for a project, and none of the suspension manufacturers I contacted had any CAD models for me to fit this into, so I couldn't check the fitment visually other than off dimensions, and I am a visual person.The other reason is that unfortunately, no one on GrabCad has any models either, which was unfortunate, so I had to go do the work myself, which is fine, if not a bit tedious.However, now that it is done, please feel free to use this to check your own designs, I haven't added any linkages between parts so if you try and move them, they will fly off out of alignment, so make sure you do that first.
