nige90 Posted July 23, 2007 Share Posted July 23, 2007 Was puzzling this with a mate over a cheeky pint at lunchtime, Why are propshafts still on UJ's and not CV joints ? I'm assuming there is a reason which some kind person/people will enlighten me to. Quote Link to comment Share on other sites More sharing options...
SHAVED_GORILLA Posted July 23, 2007 Share Posted July 23, 2007 The only reason I can assume is cost of a CV compared to a UJ. Andy Quote Link to comment Share on other sites More sharing options...
western Posted July 23, 2007 Share Posted July 23, 2007 & size of CV's/rubber gaiters that would be ripped off/open when off road. Quote Link to comment Share on other sites More sharing options...
Gromit Posted July 23, 2007 Share Posted July 23, 2007 if it was CVs it would all just work and provide no mechanical entertainment at all trying to sort out any nasty vibrations. Where's the fun in that? Quote Link to comment Share on other sites More sharing options...

bill van snorkle Posted July 23, 2007 Share Posted July 23, 2007 Birfield type cV joints have been used in some car applications where the operating angles are quite gentle, but apparently have a tendency to overheat in high angle applications at propshaft speeds that on a LandRover can be around 3 1/2 times faster than halfshaft speeds. Twin UJ (double Hooke) type cv joints are heavy and don't particularly like high angularity at high RPM either because the equalising ball and socket has to work hard under a poor lubrication environment.

Tonk Posted July 24, 2007 Share Posted July 24, 2007 What Bill says, they're good for about 3k revs AFAIK Quote Link to comment Share on other sites More sharing options...
