Load transferring shaft on control arm - material?

[johnd100]

Hi,

My suspension uses two link shafts to transfer the movement from the control arm to the shock absorber via a cam link.

I am looking to manufacture some of these link shafts and was debating the best material to use. I assume the main loads are going to be bending loads and to this end I was thinking something along the lines of rolled 4130 bar. I'm pretty sure the OEM manufacturer won't tell me what they use so would be interested in anyone's feedback.

I've attached a basic diagram of the arrangement. Two round shafts that taper to locate with a threaded end to lock in place.

Many thanks

John

can you post a picture of the current setup instead?

Hi,

Ill endeavour to get a couple of pics up. Basically they are two swivel joints that use a supported shaft with a ball joint type end. They are non serviceable but I am now thinking of modifying the housings to use the existing shafts and make an adjustable servicable joint rather than use new shafts.
