Post subject:  Collapsable Steering Column

Hi Everyone,

I am currently building a Mini Swift GTi, (Clubman), and I had the first visit from Troy Brodie of "Fink Engineering and Vehicle Certification". He was happy with everything that had been done. He informed me that I would have to put a Collapsible Steering Column in the car.

Has anyone got information on who can help with this? I have been thinking since I got to have a collapsible column I might go with an electric steering. I seen these on ebay UK, but I can't tell if they are collapsible. Does anyone have any info them or maybe someone building them in Australia?

The car probably already has a column that complies to the ADR.
Check the compliance plate for ADR10.

The steering column I have does not comply.

I wonder why not? It is a Clubman isn't it?
All Australian built Minis after 1 Jan 1971 were all built to meet ADR10a for Steering columns.

It is not the actually the that collapses on a Mini. It is the way it is mounted that pivots the solid column away from the driver in an accident.

Take a look at https://infrastructure.gov.au/roads/mot ... df/10A.pdf

I suspect that the early 70's minis were able to comply with ADR10 due to the upright angle of the column meaning that during the test the steering wheel may have been pushed towards the windscreen without exceeding the test limit.

The test may have not been that difficult to comply with.
22 feet per second is only 15mph or 24kph, a 75-80 pound body block mass is only 34-36kg... so we are sort of simulating a 35 kilogram person hitting the steering wheel in a 24kph front end accident with no seat belt.

If my suspicion is correct... fitting a column drop bracket would be a problem on '71 and later cars!

Tim.

Out of interest, some photos of the Clubman crash testing are here - viewtopic.php?f=2&t=85906

They made a lot of changes to the dash structure, pedal box and column mounts to make it work properly but yes, that is how it works.
Some engineers get fooled because the column doesn't telescope like most other vehicles but it doesn't actually need to.

If the OP really wants an electric power steering unit talk to "Convertible Mini" here, he has done this to a couple of cars.

That was likely the case for the 73 and later cars that needed to comply with ADR 10b where the test detail was tightened up and the test speed doubled to a minimum of 48kph. The photos in Winabbey's linked thread would have likely been the later ADR 10b testing.

As well as hearing of later columns being adapted, I believe a lot of racers were using a pair of off-set uni's to create a collapsible lower section. I am not aware of any engineer involvement in any though or whether similar has been used on the street.

Using an OEM collapsible 'system' will likely be significantly cheaper for the engineer to sign off on, even with the EPAS adapted.

if upgrading your engine to anything fairly new you SHOULD CONSIDER A collapsible steering column to suit. Some adapt an existing column - i have opted for Alien retro columns in Vic to make a new custom unit. Hopefully this means that future mini conversions have a design on hand to use IF YOU ARE OPTING FOR THAT

I think your ginger beer might be setting a precedent here (possibly a "dangerous" precedent)...there are many conversions on the road where a collapsible steering column wasn't a "requirement" :?

I think they use Holden barina colomns.
