How many collapsable items do I need?
corrado vr6 - 4/11/13 at 06:58 PM

Hi there, well the other day my Mk Indy with Mnr paddleshift kit failed IVA due to not have an upper collapsable item, does the IVA manual state how many items you need, as I've checked the manual myself and I couldn't find anywhere where it states one or two items needed

Here's the items I have not sure if any are classed as collapsable but if they are and the manual only states you need one item I may have to get in touch with my tester to see what he says








Thanks in advance as I know this has almost been done to death on here

The "collapse on the Sierra column is a) where the triangle bit slides into tjhe round bit( the other end of your first pic) and b) the corrugated/ribbed tube bit behind the wheel, so you may well vae 2 aleready.

Intersingly IIRC a member here that recently failed (xcant remember who) was told 2 U/j's with sufficient offeset wrer supffficient

Ah I see, I was told by Mnr that the 2nd pic was the collapsable part that suffices for them


ReMan - 4/11/13 at 07:27 PM

Sorry I got your pics confused,. You are correct. Your 1st pic is the slide. your 2nd pic is just the clamp, that is non-moving and your 3rd pic the rubber UJ as I understand is just for vibration and not a break point either

Sounds like I'm going to have to get a collapasable boss just a shame it'll space my steering wheel so far away from my paddleshift paddles


ReMan - 4/11/13 at 07:45 PM

Sorry you've lost me.
Which bitrs of the Sierra column DONT you have then?


corrado vr6 - 4/11/13 at 07:48 PM

Those pics are from my car so I have all those, however I got the impression you were saying These weren't sufficient, so which pic would be considered the collapsable item

Sorry I'm missing the convulated upper section I believe

No sorry, on the contrary, and I've searched an found ita was your your IVa fail thread I read!!! where Blake82 advises that there is "potentially" no requirement for a collapsible pice anyway. But if tyou have the sliding triangle, then that should be enough, I woukld have thought.?............


corrado vr6 - 4/11/13 at 08:26 PM

I did try and and argue with the tester that when I had spoken to Mnr I was informed that the sliding triangle piece would move down in the event of a collision however my tester wanted an upper collapsable section too, but I was hoping if the manual only stated one was necessary then I would argue a bit more that my car meets the requirements stated in the manual


ReMan - 4/11/13 at 08:37 PM

Well I've just read the IVA manual (I hadnt before) and as it reads to me, having ANY colliapsible part is good and adequate.
It certainly does not read that the wheel HAS TO collapse away from the driver IMHO

Well my column doesn't collapse, the inspector checked for a sliding bottom section OR two offset UJ's.

Cool, so from both replys it's looking like my tester either isn't upto date with the manual (he did have to refer back to it during the test) or he isn't following it, I'm not sure on my best cause of action should be wether to write an email/letter to the southampton test center explaining that after consulting the manual it would seem an upper section is not asked for


adithorp - 4/11/13 at 09:19 PM

The column has to protect you impact from both directions.

So the lower section must be either collapsible or have enough offset on the UJ's to absorb impact from the front, so the column won't come back and spear you. You have this.

In addition to this, in case you fly forward into the column, the top of the column/wheel must collapse. That requires either a breakable column mount, a collapsible top outer tube, a deformable wheel or a collapsible boss. The donor wheel or an aftermarket wheel boss usually cover this.


davidimurray - 4/11/13 at 10:05 PM

I don't think there is a requirement for the min number of collapsible elements, but what the manual judges against is:-

4. The vehicle and steering column assembly must be designed such that in the event of a frontal impact at 48km/h (30mph) the rearward horizontal displacement and vertical displacement of the top of the steering column and its shaft do not exceed 127mm. The vehicle should be assessed using the material in Annex 1

Sorry to hijack this thread but linked to the column... There is a UJ that clamps to the triangular section of the column. Does this solely rely on clamping force or it it pinned in some way?

Thanks

From memory it is not pinned


corrado vr6 - 5/11/13 at 08:23 AM

My picture 2 is pinned

Hi
We had the same problem.
Had this

Flappy modification

he wanted this

boss

so had to make these expensive paddle extensions
worked fine & passed IVA.





Took it all off after IVA.
To my mind it was an expensive overkill as we already had
2 collapsible sections.
sold the boss,
Could not sell the extensions as we made them for our specific paddle shift.

Mine isn't pinned, just clamped in place by the rivet one side and two bolts the other side. If it's pinned that would mean it cannot slide up the triangular section - see Figure 3 on P120 of the IVA manaual. It looks as though yours has been pinned and hence defeated the sliding part.


corrado vr6 - 5/11/13 at 10:05 AM

Apparently the pin is designed to snap according to Mnr

And paddle extensions sounds like a plan


adithorp - 5/11/13 at 10:16 AM

On the UJ to triangular clamp early ones had a roll pin on one edge that located in a holeon the UJ side and later ones don't. It's not needed.
