dislocation does it help !!!!!!

[Porny]

Forgive me I've being stupid here, but the whole idea of fitting a cone is to GUIDE THE SPRING back into position after you have caused it pop out of it's mounting.

The fitting of the cone cannot affect your ability to get more "droop". Fitting them to my Discovery would be *pointless* as I still have my anti-roll bars - and hence, my suspension won't drop away *unless* both rear wheels are hanging over nothing...and then I am at the mercy of my brake lines!

Very true....

Droop is also affected by the travel of the shock absorbers, and the point at which the rear radius arms, and rear A-frame bind (i.e. reach limit of movement on bushes and joint) but (as already mentioned) with a dislocated spring there is no downward force acting on the wheel, thus the wheel will not provide any traction.
So extra droop, IMHO, is pointless.

This is one possible way around it http://www.red-ibex.com/rear_suspension.htm ... even so I doubt the down force applied to the wheel will be enough to get traction.

I am of the firm belief that if my springs are in position, I am exterting downforce onto my axles .... if they were not in place....I'd be looking "cool" - but skipping my wheels along achieving nothing and going nowhere... think about it - we don't rock crawl here - in mud the thing we lose is TRACTION ..... and fitting cones to get more traction is like trying to use a fireguard made of chocolote.....

Each to his own but in my opinion this cone thing is not being explained in it's full context and I'm probably not capable of exlaining the full merits of a suspension system that has cones as 'part' of it's setup. In either case I don't think anyone should simple disregard someone elses opinion.

I believe the original point of Ians conversation was "do you get more traction from a wheel thats allowed to touch the ground or from a wheel thats hanging in the air?"...I think this is the fundemental point that those who are pro cones are trying to make. Surely a wheel that touches the ground must have more traction than a wheel that doesn't. Whether it actually makes a difference is yet to be proven. How you allow this wheel to touch the ground is what we are all argueing about.

A cone on it's own, probably won't make enough difference but most who fit cones also make other modifications to allow more articulation, which should make the difference on the right terrain !!

I'd also like to put my money on the fact that the 'boghill of impossiblity' will not conclude whether cones are the deciding factor.

See, told you I couldn't explain it clearly :-(

[Thrasher]

Mace,

Here's my take - no-one elses :-)

When one wheel is floating in the air - and you have no lockers - it is spinning freely and no power (well not much) is going to the wheel *with* traction.

If you then drop the spinning wheel down onto the ground by moving forward/backward with the wheels *with traction*, with SUFFICIENT downforce, it will grab (hopefully not too much power is being applied!) and gain traction.

If you wait for the wheel to eventually hit the ground using either gravity or some magic force, downforce will be minimum, and the simple fact it is spinning will make it "bounce" back up in accordance with physics (equal and opposite reaction and all that). Can't see how much traction would be gained from this "skittering" approach.

In the US special "shocks" (more like hydraulic rams IMHO!) are used with remote tanks which provide the required downforce to push the wheel/axle down onto the ground - these are low speed manouvers and are not generally mud based.

Having watched a vehicle with all the toys (extreme) fitted tackle a cross axle (apart from the awful sound of it pinging and clanging back into place) - it performed no better then the Series 2 on leafs that followed it (which was a damn site quiter and did not attempt to roll on it's axis!)

*adendum!

Remember the locker is there to enable the wheel *with* traction to do it's job. Similarly the new whizz bang traction enhancement systems on the RR, D3 and Sport do a similar thing, by braking the spinning wheel and allowing the wheels ON the ground, with traction to do their stuff :-)

[Mace]

Thrasher, I cannot argue with anything you've said which is why i believe trying to cross the boghill won't prove a thing. But simply (not your words) disregarding cones as a waste of time is incorrect. They do have their merits when used as part of a suspension set up.

[Thrasher]

I didn't say they were a waste of time :-)

I said : "Forgive me I've being stupid here, but the whole idea of fitting a cone is to GUIDE THE SPRING back into position after you have caused it pop out of it's mounting."

The best test would be to get 1 of each vehicle to drive over a cross axle that would stop a vehicle without a centre difflock - then drive each over and see how they react. The newer vehicles will do the cross axle in different way to the older ones - by merit of their monocoque design....

[Mace]

as I said Neil...not your words :-)

[muddyweb]

Forget the cones...  as I have said before, they make no difference to the suspension travel.  

The question was "Does dislocation help ?",  and that is a wholly more complex discussion.

[Thrasher]

I think I've made my opinion of dislocating suspension known.

Although, to be fair, if your garage was at the top of an RTI Ramp it might be worth it   :(vamp):

[datalas]

well,  as was painfully pointed out to me, the silly things are "relocation" cones not "dislocation" cones,  make that simple change in name and things become clearer :)

As for the concept of dislocating suspension, well most of the places you run out of traction in this country are because of being up to your diffpan in clag of (in most ARC events) a lack of turning circle, how having it's bottom fall off going over bumps in these cases would help is open for discussion.

If you're rock crawling, or doing something equally peculiar then a forced articulation system can probably help, but I've seen around about *no* cases in this country where it would assist, especially not in traditional trials.    Learning the inside and out of the vehicle, and (if ruling permits) investing in a set of lockers would seem a better option to me.

sort of what i suggested but everyone is taking it in dfferent ways  :? and was only ment to be a bit of general banter, but may be getting a litle out of hand  :lol:

All boils down to “each to their own”, everyone comes up with that soon as the spring dislocates traction is lost. But when fitting the cones I can get an easy a 2+ inch gap before tyre starts to lift off floor (not got any shock drop adaptors yet). Up till the point when shock stops and starts lifting the axle the tyre is still compressed a little so meaning force is still applied (maybe mine is just the odd one out).

I know people keep saying it doesn’t help through deep mud, but I never said it would. If I could afford to blow £1000+ on front and rear lockers I would. but for the limited use they would get I don’t see the point, as for spending £30 to get that little bit of help on crossing the odd obstacle it’s more realistic for what I want, it boils down to each to their own again.

Take it nobody noticed how the vehicle with spring relocators seem to out perform the fixed ones in getting up the ramp at Gaydon !!!! so somehow they are able to keep traction longer thus getting further up the ramp, maybe they believe in the FORCE and they will themselves up there   :roll: .

So basically you want to do mud runs you maybe need big grippy tyres and a lot of right foot  :twisted: .

Or if you want to do technical bits like climbs and obstacles maybe suspension mods might help. (I know your all gunna say I can get up any hill with my V8 and foot to the floor but not everyone’s the same!!!!!! And why should we be!!!!)

[Thrasher]

My V8 climbs hill with gentle throttle application - it's the torque that helps, not the heavy foot and spinning wheels. Also, the LSD's help too.

Oh....and CLEARANCE UNDER THE DIFFS :-)

[muddyweb]

I've been staying out of this, had this discussion far too many times...  but a couple of observations....

The guy in the picture below did very well up the ramp... he's on leaf springs ;-)

I don't believe that just by adding something to give you more droop travel will imrpove your vehicle's ability in a real-world situation.  I would suspect than many of the vehicles on the ramp with location cones also have long-travel springs and other suspension modifications... so don't assume that just allowing your springs away from the chassis is going to make things better.... don't forget that doing so also brings with it a number of additional problems.

If you are interested in driving up metal ramps on tarmac, then many of these systems are very good... but when all is said an done, there is no substitute for choosing the right line and driving it properly  ;-)

its a 110 - so its gonna get at least 20" further than a 90!   :shock:

I think that Eeyore may have a rear locker.

as you say each to their own - most people are not seeing the merits of them but go buy them as you clearly want to, then every time you get stuck we will take the mick!!!  (in a nice way)
   :D


make that 2 sets , andy needs some as well  :D  

[Thrasher]

I love my Tru-tracs :-)

Only need one mate, got one fitted already, tother one I broke. Thats why Tim helped me at Whaddon and you helped me at Sibbertoft, coz me springs they were a poppin.

Dave, you have my permission to take the mick as often as you like too. As long as you all get value for money on the entertainment front, i don't care. I don't take life too seriously.

Hoorah for Mud-Club  :(biggrin):

not may off-roaders can't take a litle joke, as wouldn't make sense driving in to a mud hole knowing your not going to get out and making a fool of yourselves, or buying a V8 that hate water with typical english weater  :lol:  :lol:

[Thrasher]

Hehe,

Just ask yourself why so many classic British sportscars have to no roof! Odd  ... very odd given our climate ;-)

[Wanderer]

The best thing I ever did on Snorkly was to fit relocation cones.

It saved Neil having to keep getting his hi lift off his motor to put my springs back in at Tixover :)

Ed

[Eeyore]

Just to add a tuppence:
My views on dislocation are equally well known and far too anorak for words! Suffice to say I've met a lot of vehicle designers and engineers in my time.

Flower, sadly, doesn't have a locker (yet.....) but will happily pop springs all day if pushed. I'm easy with this as the very hard springing (she has been known to carry big loads a very long way) limits the compression upwards, so I compensate by dangling further. Works for me.

Interestingly, the other 110 pictured earlier has no dampers (go check if you don't beleive me) - these will limit droop. You'll also not know that the spring is his case is fastened at the top and dislocates from the bottom.

cheers

Personally I look at them as being an easier way of relocating things when they do get out of shape.

My main worry would be leaving a site with a spring that has been out and had then reseated wrongly sitting on the edge of the spring seat. Then travelling at any speed on the motorway going home and the spring suddenly deciding to jump back into its proper location and having an adverse momentary effect on the vehicles handling.

So the question should really be. Should the suspension be allowed to "dislocate" in the first place.
It's nearly as bad as Should I vote Labour Conservative or LibDem?

Monster Raving Loony Party for me!

A bit of a tip that helped me though is to situate the spring in such a way that the rounded part of the spring makes the first contact with the seat as it will rub and guide itself back in whereas the flat part of the spring will catch and not reseat even with the cones fitted.

Sorry to be a spoil sport but thats a coil sprung series 2
like i said, sorry :oops:

[muddyweb]

Fair enough, but I maintain my opinion that you are better off driving well to get past an obstacle than hoping an unseated axle will help.

The other thing is that if you look at the piccy, he has a rear wheel off the ground and the front end has both wheels planted.  Not sure if there is a locker at work there or not, but there wouldn't *need* to be.

There are heaps of things going on as the suspension of a vehicle works, and I stand by my view that the RTi test is pretty meaningless outside its own results.  

You can design a vehicle to do well on the ramp, but that won't necessarily make it good off-road, and as I have said before, dislocation brings with it as many problems as it claims to solve.

[Xtremeteam]

dunno who said it but the first pic does hav shockies fitted to the motor,just not in the usual place 8)  go force n look my son u shall see they are mounted inwardly

[davidlandy]

its official - relocation/dislocation cones do not work

I hereby formally announce this topic exhausted and the thread finished.

Thank you

so ypu both got stuck then?? :lol:
