Talk:Rag joint

Patent
I am not sure if it is the same thing, but this might be worth citing in the article: http://v3.espacenet.com/publicationDetails/biblio?CC=GB&NR=497903&KC=&FT=E


 * It is the same thing. — Preceding unsigned comment added by 114.73.105.109 (talk) 12:36, 25 August 2011 (UTC)

Vague claims

 * An older vehicle with loose steering
 * older than when? or what?


 * this is unacceptable
 * according to who? where? In the US? In Nigeria?

Proposed merge from Giubo
According to this article rag joints are used on both steering linkages and drive shaft linkages. Seeing how giubos are just rag joints used on drive shaft linkages, I don't see how they aren't the same thing. As such, the giubo article should be merge here and a note made that sometimes when rag joints are used on drive shafts they are known as giubos. Moreover, giubo appears to be trademarked name.

 * They're used for the same purpose, but they're not the same thing. One is made of cloth or leather in a flat disk, the other is a rubber doughnut. As the giubos are thicker, they can transmit more power and have almost entirely replaced rag joints for power transmission in vehicles.
 * I'd support the merge, but it needs to have some expansion incorporated too, to explain the historical sequence. A simple paste would leave a very confused article. Andy Dingley (talk) 17:59, 14 June 2011 (UTC)


 * Andy, in my experience every "rag joint" on a steering linkage I've works on is rubber, so I lack to see the difference between a giubo and rag joint. Agreed there would be some cleanup to do if a merge occurs. Wizard191 (talk) 19:05, 14 June 2011 (UTC)


 * The difference is less about the materials, more about the shape. A "rag joint" uses a disk, so that it has lots of articulation but little material to transmit the torque. A giubo is a thick doughnut, with the bolts passing through tubes, not just short holes. You can't use a rag joint for power transmission on modern cars, either in the prop shaft or the half shafts - it would wind up under the torque. Even my Fiat Panda used a giubo for the rear driveshaft, not a rag joint (mind you, Italians took to using these things first, in the early '60s, hence the name). Giubo are also installed pre-loaded, so that they never go into tension - if they do, the glued joint soon breaks. They're installed with a big band clamp around them.
 * I haven't seen a rag joint in a steering linkage for years, don't think I've ever seen a rubber one here for articulation, although a few for vibration isolation. Practice these days is generally an all-metal coupling. I wouldn't be too surprised to see a rubber disk as a joint, but not a fat doughnut. Andy Dingley (talk) 19:20, 14 June 2011 (UTC)


 * My Mustangs use them: http://www.latemodelrestoration.com/item/DOR-31000/79-93-Mustang-Steering-Shaft-Rag-Joint. I'm also familiar with Giubos because my BMW has one. Other than size and metal sleeves in the through holes, they serve the same purpose utilizing the same principles, which is why I categorize them as the same thing.

 * "Rag joint" is a colloquial U.S. term for what is correctly a "Hardy coupling" in English. Look at the wiki source for the photo in the article for confirmation. The "Guibo" is the same principle (and merely the Italian name) so a merger and expansion under a more appropriate name of "Flexible coupling" or "Flexible joint" would be appropriate. Flexible couplings are used for power transmission in many industries apart from the automotive industry. And as for "guibos" dating from the 1960's, that's about 60 years late. — Preceding unsigned comment added by 114.73.105.109 (talk) 12:30, 25 August 2011 (UTC)


 * I'm inclined to merge these, but what should the resultant name be? Flexible coupling is too broad, there are a great many sort of those. Andy Dingley (talk) 16:26, 5 June 2013 (UTC)


 * I've always heard them called giubo joints. But ETKA calls them a "steering coupling" even on the propeller shaft, and BMW's catalogue calls them a u-joint. So i guess it depends on the use for what different manufacturers call it? If it's kept separate I'd put it under the name "Giubo Joint."  Otherwise if its going to be merged with something I'd suggest to add a section that includes several types of couplings such as u-joints, cv-joints, etc...  — Preceding unsigned comment added by 24.158.23.166 (talk) 19:22, 26 February 2014 (UTC)
