o_teunico Posted March 5, 2013 Share Posted March 5, 2013 Have seen this in one of the cars from Tornado Motorport... ...and I was guessing if this kind of arrangement could be used as an option instead of traditional portal axles. They seem light and could be made 100% Rover with diffs, shafts, hubs, etc. from scrap/secondhand parts from L322 Rangies, Disco 3/4 or RRS. Parts from a 500HP RR in a Tdi Disco 1 will certainly become bombproof. Quote Link to comment Share on other sites More sharing options...
simonr Posted March 5, 2013 Share Posted March 5, 2013 It's a good idea - similar in many ways to the 'dijon' suspension used on Rover P6's Si Quote Link to comment Share on other sites More sharing options...

steve b Posted March 5, 2013 Share Posted March 5, 2013 We make those rear x-members for Tornado , CNC HD plasma and a couple of press ops , the axle layout is a good solution for underaxle clearance and also lighter than the rover axle assy cheers Steveb Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted March 5, 2013 Share Posted March 5, 2013 You can already by an axle in the us that works off the same principle. Quite clever, but what I don't like is even more parts to fail/ wear out. But then again compared to portals it's no worse as the portals have so many extra seals bearings and gears.

ian_s Posted March 5, 2013 Share Posted March 5, 2013 looking at the photo, it's basically a diff from and independent suspension setup, welded into a frame to make a solid axle, using 4 cv joints? i can see it working well at the rear, but at the front the outer CV joint may restrict the amount of lock possible Quote Link to comment Share on other sites More sharing options...

I have to admit, I like it a lot!!! looking at the photo, it's basically a diff from and independent suspension setup, welded into a frame to make a solid axle, using 4 cv joints? i can see it working well at the rear, but at the front the outer CV joint may restrict the amount of lock possible True But do they have an offering for the front at all? If so it would be nice to see it!!! Quote Link to comment Share on other sites More sharing options...
dirtyninety Posted March 5, 2013 Share Posted March 5, 2013 Its Matt Lee, owner of Matt Lee MACH 5's that build these axles. I think there is only one in existence on the back of his Tornado. Tornado Motorsport is owned by his cousin, Dave Billings. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted March 5, 2013 Share Posted March 5, 2013 as the portals have so many extra seals bearings and gears. Portals don't have that much extra than a regular axle... really just an extra stub axle with a gear & bearings on it. I've never found myself thinking "oh damn all these extra complications" when working on my portals. Quote Link to comment Share on other sites More sharing options...
elbekko Posted March 5, 2013 Share Posted March 5, 2013 The front hubs make you think "why do we need 3 guys for this" though Quote Link to comment Share on other sites More sharing options...
greenstream Posted March 5, 2013 Share Posted March 5, 2013 The car in the photo is 2-wheeldrive. Made with a special "bolt-on" arrangement at the front, no beam but indy. All in all a rahter nice car, with some great details. Morten Quote Link to comment Share on other sites More sharing options...

I've never found myself thinking "oh damn all these extra complications" when working on my portals. Me neither per se.. But I must admit that after having messed with any other axle out there, when I get to my stock Series axle I laugh at how easy it is to service. And no matter how you put it, one more bearing = one more thing to service. On regards to the axle shown, I've seen plenty people do the similar to the IFS on Pajero. Basically making a cradle to fix everything, and then make links and suspension. I nice way to get a solid axle with the benefits of independent but without the offroad disadvantages Quote Link to comment Share on other sites More sharing options...

Soren Frimodt Posted March 5, 2013 Share Posted March 5, 2013 Looks pretty cool I must say! Could be fun building a 2wd offroader, just afraid I won't have anywhere fun to use it here in Denmark though.. Quote Link to comment Share on other sites More sharing options...
Cynic-al Posted March 5, 2013 Share Posted March 5, 2013 Saw this on a buggy someone made but they kept the independent suspension for smoothing the bumps at speed and had them connected like a beam axle for greater flex. They used shogun parts as apparently they are relatively cheap, strong and available with factory fit lockers. Quote Link to comment Share on other sites More sharing options...

o_teunico Posted March 6, 2013 Author Share Posted March 6, 2013 Si, it´s maybe time of developing the x-portal axle with those parts from the twisting Vitara buggy. Quote Link to comment Share on other sites More sharing options...
bill van snorkle Posted March 6, 2013 Share Posted March 6, 2013 Have seen this in one of the cars from Tornado Motorport... ...and I was guessing if this kind of arrangement could be used as an option instead of traditional portal axles. Still a couple of disadvantages compared to portals. 1/ no gear reduction to reduce the strain on the diffs. 2/ whilst clearance under differential is improved by about 3'', the clearance under axle tubes isn't. 3/ This design is more suited to axles with centred differentials. On vehicles such as LandRovers with offcentre differentials, the halfshaft CV/U joints would be operating at a constant severe angle, particularly the very short right hand front. I prefer oil lubricated CV's and hub bearings.This design would require both being grease lubed. Unimog portals may be difficult to work on and maintain ,with their enormous press fit tolerances, but Volvo, Maxidrive, and my own full floater portals are a piece of cake.

o_teunico Posted March 6, 2013 Author Share Posted March 6, 2013 Hummers are independent+portal. Also have CTIS and double beadlocks. Early ones are more than 20 years old now. If the parts could be cheaply sourced and posted from US... This pic is from pirate4x4. Uses Hummer parts, but they have left halfshafts laying horizontaly. With halfshafts in "suspension drop" position it could be a super-portal with maybe +8" extra clearance. Only problem in Europe will be sourcing tyres for Hummer´s 16.5" rim.

Soren Frimodt Posted March 6, 2013 Share Posted March 6, 2013 Yes but you really don't need anymore lift than Volvo's and Mog's offer, because with stock soft RRC springs allround to keep the cog low, the lowest point suddently becomes transfer box, exhaust, handbrake etc.. And if you should desire more lift what about some portals off of an Ursus tractor? Bevel drive and very high! We have a Toyota hybrid running these in Denmark Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted March 6, 2013 Share Posted March 6, 2013 The question is; what does it gain you? Is it cheaper, simpler, stronger, more reliable...? I don't know if it would be any better to have some custom-made thing like that using bits of Hummers and whatever under my truck instead of the Volvos.

o_teunico Posted March 6, 2013 Author Share Posted March 6, 2013 My brain is building an image of a Hummer-Jaguar XJS Dana 60 axle under a Landy. Mmmmmmmmmmm... This picture from a Hummer hub has been taken from pirate4x4. Mog 404 parts seem beefer... http://www.pirate4x4.com/forum/mercedes/116600-hybrid-hummer-axles-versus-mog-hybrid-axles.html Quote Link to comment Share on other sites More sharing options...
o_teunico Posted March 6, 2013 Author Share Posted March 6, 2013 Now can´t take the Hummer hub image out of my head! Maybe the hub could be converted to Rover wheel stud pattern, in a similar way as was made in the Spidetrax 90 from pirate4x4. Anothe advantage of the Hummer design is that brakes are out of the harms way in the diff, and not in the hub. Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted March 6, 2013 Share Posted March 6, 2013 Correct me if I'm wrong, but is there not a mount in both ends (top and bottom) of that Hummer portal box for suspension links? If so then where's the portal effect? Quote Link to comment Share on other sites More sharing options...
