Warning! It's my day off YAY and I'm thinking aloud. Excuse the edits while I figure stuff out.
I'm googling for photographs of wishbone suspension arrangements and am attempting to understand why some engineers have chosen to play about with the humble wishbone. Take two piece wishbones. As an example, here's the front suspension off of a Mallock. It appears to be that the diagonal / trailing tube can be adjusted for length in addition to the leading one. Is this to deliberately adjust castor? [EDIT] It's just occured to me, the threaded rose joint to adjust camber is on the chassis side and 'cos the diagonal tube pickup is not 90 degrees to the chassis ... bla trigonometry bla. Is then the intention to spread the forces applied to the suspension between two rose joints [assuming the thread is the weak point] instead of one? Doesn't this overcomplicate things? Has anyone heard of rose joints failing at the thread? Or am I still thinking along the wrong lines? [/EDIT]
How are the two parts held together. Is there a spherical bearing in there or merely a bush? I'm assuming a bush! While I'm at it, how do you hold spherical bearings in place? Circlips? In which case, how do manufacturers machine the groove inside the piece of steel?
Can I just recommend Bill's website. It's been in my favourites for a while; I think he reads Blat. The Mallock is his. He's made the 4AGE look a tempting alternative to a Zetec upgrade.
Isn't the rear suspension on this old Lotus 7 nice. In board brakes, too. I think there were some pics in Low Flying a while back. Can anyone shed any more light? That or a CSR? I know which I'd have !
