double UJ'd propshafts

TDi90:
recently seen these? whats the difference to a normal one UJ'd propshaft? how does it aid it?

smo:
I presume you mean a double cardon prop...essentially 2 uj's mounted back to back at one end (it more complicated than that as its self supporting!) to allow much greater angles of use wihtout binding.

Standard on disco II''s and aftermarket fittet to many a defender etc when fitted wiht a large lift as they can handle the odd drive angles created.

clbarclay:
As smo says, except its cardon joint, a double cardon joint would be the equiverlant of 4 UJs or a cardon joint at each end of the propshaft.

The important difereance is that in a cardon joint the spiders are linked together so that they are at exactly the same angle all the time. Just using 2 normal UJs at one end of a prop shaft does not work.

The advantages of cardon joints over convetional UJs are reduce vibrations and because the angle is shared between 2 joints the propshaft can work at a greater angle.


Search for 'cardon' using the mud club search (top middle of the page) there is already a wealth of information on this site alone.

You *can* put two ujs together and it can work really well, assuming you're wanting to produce a mechanical hybrid between a bass drum and a skipping rope :D
