Quick release steering wheels.
Gav - 6/5/06 at 07:28 PM

How are quick release steering wheels viewed in relation to sva? ok as long as the boss is collapsable?.

What ive done is machined a recess into a willwood quick release boss so that the sierra collapsable collumn thingy sits into it so the steering wheel is kept nice and steady and hopfully that will suffice as far as a collapseable boss is concered, or are their other issues with quick release systems?

You do not need a colapsable boss if there is a direction change in your steering colomn, such as 2 UJ's.

ISTR the SVA people dont like removeable steering wheels as they dont for a permanent part of the car. I stand to be corrected though, but I am sure someones mentioed it before...

When not stick with the sierra wheel until after sva?

The boss has a hex bar that you weld onto the column, would rather do it now than bugger about taking the column to bits later.
Also it looks a damn sight neater than the mouldy old sierra wheel!

Ariel Atoms have a removeable steering wheel as standard.
Just show the SVA man a picture

Yep, but don't you need the collapsable upper shaft (as per the SVA manual) to minimise driver to wheel impact ?

Thats what i was thinking, hence machining a groove for the sierra upper collapsable thingy to sit into, rather than having to make something crap from scratch

No, you just need a pad on the steering wheel.
What the sva is looking for is a frontal impact pushing the colomn into the driver.
Like I said.........if the column is in 2 pieces with angled UJ's so that the colomn will fold, then that is ok.
Alternatively a sliding colomn with a colapsable cage section between the bolted top section and the bulkhead.
The steering wheel should be designed to stay fixed in an accident, not wait for you to hit it to collapse it

OT a bit but does anyone know what type of quick release I would need to put on my mgb shaft and wheel. I want for both ease of getting in and out and to move the wheel a couple of inches closer to the driver.

Hi,

The way I read it wa to have both the dogleg and sliding shaft bit and then a colapsible section in front of the bracket that holds the upper column so if the driver impact the steering wheel, it has some give.

"The wheel and column assembly must be capable of controlling the rate of decelaration of the impacting body by the use of compressible material or deformarion".

Humm,
ive used the rubber cush donut at the rack end, but the column is still at an angle to it, perhps id be better replacing it with a UJ?

I've got 2 solid uj's, but the column is doglegged a bit.

Also got the standard Sierra sliding traingular bit, the compressible black bit and a collapsible boss.
