Matt Vandart Posted December 13, 2010 Report Share Posted December 13, 2010 I read in a topic on OTN that kings have 24 engagements more. I am not disputing this fact in any way shape or form. What I would like to know is how they actually work. I was under the impression that they work in a completely different way to 'normal' hubs and freewheels, and that action was of a fast thread pulling a drive ring onto a driven ring. Is this correct? Would that not mean that there is no 'real' number of engagements but the drive is pretty much instantaneous? Can the gap between the drive ring and the driven ring be adjusted to make it smaller and thus more instantaneous or bigger and thus less instantaneous? Have I got this completely wrong or dreamed it or made it up? Thanks in advance of your wonderfully decriptive answers. Quote Link to comment Share on other sites More sharing options...
Phatmike Posted December 13, 2010 Report Share Posted December 13, 2010 You've got it right, although the drive ring and driven ring have teeth on them - 72 in fact. In this video you can see the drive ring going on first, then the driven ring (with the male spline, which intersects with the female spline on the inside of the hub body). http://chrisking.com/files/tech_movies/hshell_r_assy.mov Then the drive shell going in, the splines on that twist the drive ring into the driven ring, engaging it. http://chrisking.com/files/tech_movies/hub_r_fin_assy.mov Quote Link to comment Share on other sites More sharing options...

Shaun H Posted December 14, 2010 Report Share Posted December 14, 2010 Would that not mean that there is no 'real' number of engagements but the drive is pretty much instantaneous? Can the gap between the drive ring and the driven ring be adjusted to make it smaller and thus more instantaneous or bigger and thus less instantaneous? There is no gap between the drive and driven rings, their teeth are constantly in contact. The rasping/buzzing sound of a King wheel spinning are the teeth on the rings riding over eachother under pressure from the drive spring. As Mike said there's 72 teeth in each ring giving 72 engagement points over a full rotation of the drive shell, the only way to get more would be to increase the number of these teeth.
