Top upright joint on a rocking arm suspension.
Hey Up
I've been designing a top rocking arm front suspension and I had been intending to use the old Transit draglink end.
I've been having doubts because of the extra load imposed transfering the spring/damper loads through the joint.
Do you chaps think that a switch to a bolt on type joint which can be backed up with a plate is necessary?
All comments welcomed
Cheers
Chris

I have a vague memory of this conversation from a long time ago. Consensus then was it wasn't up to the job. Personally i haven't a clue

Hi reaserch on the raw striker setup would be a good start.
But the trouble is that no one as yet has managed to get this setup to work properly and last any real lenght of time without issues arrising. Inc
raw.

Wasnt this a big topic on one of the cobra forums a while back, i seem to remember the bmw based cobra having the drag links or similar and getting a
right slating.
Although this car was linked to limelight/filby so it was never going to get good praise but thats another story.

The stryker uses a Metro ball joint and seems pretty well set up to me - have a look at the times recorded by Strykers when competing against other
cars with similar engines in hillclimbs and sprints and they have to be good.
I'm using the Transit link unless someone convinces me otherwise!

A proper ball joint is required ideally one designed for push in loads --- Maxi, Mini spring to mind.
With this setup you might want to consider a different method of camber adjustment.

I would have thought that the threaded portion of the transit draglink end would be an ideal site for fatigue cracking as it is subjected to repeated
and large amounts of bending force.
So not only not ideal but an accident waiting to happen IMHO

what about something like the joints dax use on the top wishbone? can't remember whether it's on the tojeiro or the rush
the bolts are perpendicular to the balljoint taper, so you can adjust camber with shims.
there may be nothing suitable in such a format, but just thought i'd throw it in.

Thanks for the replies chaps.
It was the sideways stress on the threaded part that worried me.
I have a contact at Dax, I'll give him a ring.
Re camber alteration would slotted holes with some sort of locking device do this?

I've just rooted out this picture from stoneleigh.
This set-up looks pretty good, anyone any idea where that joint is from?

That's a dax top joint - not sure what it's from but they'll be able to tell you. I'm using maxi joints on my setup.

Yeah I know, it's from the Tojerio, camber compensation set up.
Just don't know where the BJ is from!

The Tojero (Cobra) uses Jag IRS & IFS.
Obviously the top wishbone is fabricated for the camber compensation set up, but
the rest are probably Jag parts.

If it's a Jag part it should be pretty rebust

Apart from the strength of the threaded part of the drag link, the other reason not to use it is that the ball joint is spring loaded in order to
eliminate any play as it wears. By putting loads verticaly into the balljoint, the spring will be compressed and you will end up with a floppy ball
joint.

David Manners for me when asking for Jag bits
linky thing
They list a lower ball joint on the front suspension as CAC9937, its £20.56 with VAT. Although its years since I had a jag it does look familiar.

Are they spring loaded Mike? Bottom ball joints on metro etc are but these are top joints and are track rod ( drag link) ends which don't
usually have springs. Has anyone destroyed one so we can check inside?

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

1960s-90s Jag XJ6 -- part -- not designed for spring loads
Triumphs and SAAB 99 also use something similar.
The SAAB one is designed for push in balljoint loads as is the Triumph Dolomite one.
