bill van snorkle Posted September 18, 2013 Share Posted September 18, 2013 Radius arms, with the front eye cut off and the bushing hole sleeved down to take rear trailing arm chassis bushings can be used, but their weight is a bit of overkill for a 3 link setup, because the links are not subject to the same bending forces as radius arms when braking or under power. Although I have sleeved my lower front links, made from trailing arms, for extra insurance, I never did bend the originals, but that may have been due to the extra ground clearance from the portals and larger tyres.

o_teunico Posted September 18, 2013 Author Share Posted September 18, 2013 with the front eye cut off and the bushing hole sleeved down to take rear trailing arm chassis bushings can be used That idea appeals me more. I wouldn´t worry about some extra kg if that is gonna give me peace of mind. In fact QT make their (lower) 3rd link in radious arm fashion.

In fact QT make their (lower) 3rd link in radious arm fashion. I'm really not too keen on that lower 3rd link design. Being a ground clearance enthusiast, it looks all wrong to me. I acknowledge that it does effectively protect the vulnerable steering track rod, but there has to be a better way. Not sure about the geometric dynamic behaviour of that design either. There was a 3 link thread on the LandRover forum on Pirate awhile back, and the broadly similar Safari Guard system came across as the least appealing solution to gaining improved articulation.

discomikey Posted September 18, 2013 Share Posted September 18, 2013 have you thought about using the same sort of a frame principal, but incorporating it into the radius arms? kind of 4 link system? it would need some form of cleverness at the axle end in order to allow rotation in the articulation direction while restraining fore and aft rotation. bushes would limit articulation way more than the standard setup i fear just my 2p Quote Link to comment Share on other sites More sharing options...
bill van snorkle Posted September 19, 2013 Share Posted September 19, 2013 That's what Michele and I have. How does yours perform on and offroad ? I will try to find the thread discussion on Pirate, because I can't recall the actual detail of the criticisms of the SG unit. Quote Link to comment Share on other sites More sharing options...
o_teunico Posted September 19, 2013 Author Share Posted September 19, 2013 Triangulated 4link will have the same bump steer problem as the A frame. How Auverland and URO solved it is a real mistery for me. Quote Link to comment Share on other sites More sharing options...
discomikey Posted September 19, 2013 Share Posted September 19, 2013 bump steer would still be an issue but maybe could be minimised by making the drag link "over center" as the suspension travels through its arc Quote Link to comment Share on other sites More sharing options...

discomark10 Posted September 20, 2013 Share Posted September 20, 2013 What about 1 link? seems to be a good solution from what I read, not sure what the disavantages are to be honest. Quote Link to comment Share on other sites More sharing options...

So I am presuming that that, coupled with soft springs, is what has made for a lot of body roll when tipping it into corners. With attention and smooth acceleration, through the bend, the forces can be balanced out. I intend to try different spring rates though to see if the ride can be improved. Off road I really like it. The body roll does seem like its a bit much on side slopes - but other than that the balance front to back seems good. I drive as gently as possible, with open diffs and standard drive train and I find it remarkable how giving it time it will settle itself and find some grip. On rocks it feel like it gently fidgets itself into a position where it will drive. So as a bit of an ignoramus - I like it ! Quote Link to comment Share on other sites More sharing options...
bill van snorkle Posted September 20, 2013 Share Posted September 20, 2013 Thanks for the reply Anderzander. The search function on Pirate didn't work for me the other day, and now I don't seem to be able to log on anymore. I'll try again a bit later once my patience returns.

o_teunico Posted September 20, 2013 Author Share Posted September 20, 2013 What about 1 link? I really like the 1ink, but I think that a 3 link made using the standard radius arms will be easier to make road legal. Quote Link to comment Share on other sites More sharing options...
o_teunico Posted September 20, 2013 Author Share Posted September 20, 2013 Forgot to measure distance between radious arms and trailing arms´ mounts on chassis, but should be about 100cm (40") if the wheelbase has to be 100". Measured it today: 94 cm. A cranked upper link (made out of an old radious arm) could be fitted from diff to gearbox crossmember, but I don´t see any other place suitable without fouling engine or box. Space will be tight, as engine mount, oil filter and clutch slave cylinder. Another option: fit 3rd (centered) link facing forward. Quote Link to comment Share on other sites More sharing options...
discomark10 Posted September 21, 2013 Share Posted September 21, 2013 Front link will just invite axle rotation (pinion angle) and you will need allot of chassis over the front axle (overhang). Quote Link to comment Share on other sites More sharing options...
